Alpha-ketoglutarate (AKG) has emerged as a promising molecule in the longevity and wellness space. But what exactly is AKG, and how does Calcium Alpha-Ketoglutarate (Ca-AKG) differ from it? This article will break down the science behind AKG, its role in aging, and why the calcium-bound form (Ca-AKG) may be the preferred choice for biohackers, aging adults, and anyone interested in anti-aging. We’ll explore their differences in bioavailability, delve into the cellular mechanisms (like NAD⁺, mitochondria, and longevity pathways) impacted by AKG, and review up-to-date research.
What is AKG (Alpha-Ketoglutarate)?
Alpha-Ketoglutarate (AKG) is a naturally occurring molecule central to metabolism. It’s a key intermediate in the Krebs cycle (citric acid cycle), which is the process cells use to generate energy (ATP) from food. AKG also plays a role in amino acid metabolism and nitrogen balance, acting as a hub in various cellular pathways. In simple terms, think of AKG as a fuel metabolite that helps your mitochondria (the cell’s power plants) produce energy efficiently.
- AKG in the Body: Our bodies produce AKG during energy metabolism. It serves as a building block for other molecules and as a fuel for cellular respiration. AKG is also a signaling molecule – for example, it’s a required cofactor for certain enzymes that regulate gene expression (like DNA/histone demethylases). This means AKG can influence epigenetic marks and cell function, beyond just energy production.
- Relevance to Aging: AKG levels tend to decline with age. In fact, human plasma AKG levels drop roughly tenfold between age 40 and 80. Lower AKG may contribute to age-related metabolic slowdown and decreased cellular repair. Research suggests maintaining higher AKG levels (through diet or supplementation) could support more youthful metabolism. For example, preserving AKG via caloric restriction was linked to better brain function in aged rats, and supplemental AKG improved blood vessel health in old mice. The natural decline of AKG with aging is one reason it’s gaining attention in longevity science.
What is Ca-AKG (Calcium Alpha-Ketoglutarate)?
Calcium AKG (Ca-AKG) is simply AKG that has been bound to a calcium molecule. This forms a salt (calcium alpha-ketoglutarate), which is the form used in most anti-aging supplements. The addition of calcium dramatically affects how the compound behaves as a supplement:
- Stability: Pure AKG is an acid (alpha-ketoglutaric acid) which is unstable on its own and can degrade quickly. By binding it to calcium, the molecule becomes more stable and suitable for consumption. This calcium salt form increases the shelf-life and prevents AKG from breaking down before it can be absorbed.
- Bioavailability and Absorption: Perhaps the biggest difference is that Ca-AKG is absorbed much better than free AKG. Studies have shown that when taking plain AKG by itself, up to 80% of it may not get absorbed – the majority is metabolized by gut tissues or excreted before reaching circulation. In contrast, the calcium-bound AKG survives digestion more effectively. The calcium helps shuttle AKG through the gut and into the bloodstream, improving its bioavailability. Additionally, calcium AKG is absorbed more slowly and steadily, which means a more prolonged effect as the AKG is released over time. Essentially, Ca-AKG acts like a time-release version of AKG, leading to sustained levels in the body.
- Effectiveness: Because of the above factors, Ca-AKG is generally considered the more effective form for supplementation. You get more AKG delivered to your cells. This is why nearly all the anti-aging research in animals (and the current human trials) use Ca-AKG rather than regular AKG. In fact, Ca-AKG is often the form referred to in longevity studies and is believed to be responsible for the beneficial effects on lifespan and healthspan (more on those studies below).
- Other Forms (AAKG, etc.): You might also encounter Arginine Alpha-Ketoglutarate (AAKG), where AKG is bound to the amino acid L-arginine. AAKG is popular in sports nutrition for boosting blood flow (as a nitric oxide precursor), but it hasn’t demonstrated the same longevity benefits as Ca-AKG. It’s mainly used for athletic performance. Similarly, AKG has been formulated with ornithine (OKG) in clinical settings (e.g. to aid malnourished patients), which showed benefits like improved wound healing in the elderly. Among all forms, Ca-AKG stands out for anti-aging purposes due to its superior absorption and usage in research.
How AKG Influences Aging – Key Mechanisms
AKG isn’t just another fuel; it has multiple effects on cellular pathways linked to aging. Here are some of the scientific mechanisms through which AKG (and Ca-AKG) may promote healthier aging:
- Mitochondrial Energy & NAD⁺ Metabolism: AKG sits in the heart of the mitochondrial energy cycle. As the Krebs cycle spins, AKG’s conversion to succinyl-CoA generates NADH, which in turn helps produce ATP (energy). Supplementing AKG can boost this process, supporting cellular energy production. Interestingly, AKG supplementation has been shown to increase NAD⁺ levels in cells, which activates sirtuins – longevity-related proteins. For example, a 2024 study in mice with heart failure found that providing AKG elevated cardiac NAD⁺ and activated the SIRT1 enzyme, leading to improved mitochondrial function and health of heart cells. NAD⁺ is crucial for metabolism and DNA repair, and it typically declines with age. By upregulating NAD⁺ and mitochondrial efficiency, AKG may help cells behave in a more “youthful” energetic state.
- AMPK Activation & mTOR Inhibition: AKG can mimic some effects of caloric restriction by influencing nutrient-sensing pathways. Research in simpler organisms has shown AKG extends lifespan by tweaking these pathways. In fruit flies, for instance, AKG supplementation extended lifespan by activating AMPK (a cellular energy sensor often activated by exercise/fasting) and inhibiting mTOR (a growth pathway that, when overactive, is linked to aging). In essence, AKG sends a signal of low energy/nutrient that flips on the cell’s stress-resilience programs (AMPK) and turns down growth signals (mTOR), potentially favoring longevity. This is similar to how caloric restriction benefits longevity, and AKG may achieve it without actual food deprivation.
- Epigenetic Regulation & Cellular Reprogramming: AKG is a cofactor for a family of enzymes called αKG-dependent dioxygenases. These include DNA demethylases (TET enzymes) and histone demethylases (like the JmjC domain enzymes) which remove epigenetic marks. During aging, certain epigenetic changes (like accumulation of methyl groups on DNA and histones) can turn genes on/off in deleterious ways. AKG availability can affect these changes. Studies have found that adding AKG can rejuvenate some cellular functions – for example, AKG helped maintain the stemness of stem cells in lab studies. In a 2020 study on aging bone, AKG supplementation reduced levels of repressive histone methylation marks (H3K9me3 and H3K27me3) in aged stem cells, essentially making the cells’ epigenetic profile look more “youthful.” This was accompanied by reduced cellular senescence (fewer old, inactive cells) in those tissues. By supporting the enzymes that refresh the epigenome, AKG might help reset some age-related changes in gene expression.
- Anti-Inflammatory & Senescence Effects: Chronic inflammation is a hallmark of aging (“inflammaging”). AKG appears to have anti-inflammatory properties. Notably, the landmark mouse study from 2020 showed that Ca-AKG supplementation led to a drop in pro-inflammatory cytokines in aged mice and a boost in IL-10, an anti-inflammatory cytokine. AKG-fed mice had lower levels of systemic inflammation, which likely helped their healthspan. AKG might also suppress the SASP (senescence-associated secretory phenotype), which is the inflammatory cocktail secreted by senescent (old) cells. By reducing the SASP, AKG can create a healthier cellular environment. This anti-inflammatory tilt can translate to less tissue damage and improved function as organisms age. The reduction in inflammation is one mechanism by which AKG reduced frailty in mice (frail mice have higher inflammation). In short, AKG helps tame the “fire” of inflammation that comes with age, thereby protecting tissues.
- Muscle and Bone Health: AKG also plays a role in musculoskeletal aging. Some effects include supporting collagen production (important for bones, joints, skin) and influencing growth factors. In aged mice, AKG supplementation increased bone mass and strength, partly by improving stem cell function in bone and altering gene activity (BMP signaling) via histone modifications. This suggests AKG might combat osteoporosis. There’s even interest from NASA: Ca-AKG was tested for preserving astronaut bone density in microgravity. On the muscle side, AKG’s ability to provide energy and reduce inflammation may help older muscles recover and maintain mass. Some users report better workout recovery with AKG. While more research is needed, the outlook is that AKG’s multifaceted support (energy, collagen synthesis, reduced inflammation) benefits bone and muscle aging.
Takeaway: AKG is not just a metabolic fuel; it’s a signaling metabolite that touches many longevity pathways – from boosting NAD⁺ (like an NAD booster) and activating sirtuins/AMPK (like fasting or exercise) to damping down mTOR and chronic inflammation (like certain longevity drugs do), and even tweaking the epigenetic clock of cells. These synergistic effects explain why scientists see AKG as a promising “anti-aging” metabolite.
Longevity and Healthspan Research on AKG vs Ca-AKG
What does the evidence show about AKG or Ca-AKG actually improving aging? Here we highlight some key studies:
- Extended Lifespan in Mice: CaAKG supplementation initiated in middle-aged mice led to a ~10% increase in median lifespan for females and a ~5% increase for males. More notably, the mice displayed improved healthspan — reduced frailty, better coat condition, sustained activity levels, and lower systemic inflammation. Researchers observed what’s called a compression of morbidity, meaning the treated mice stayed healthy much longer and experienced a shorter period of decline near the end of life. This aligns closely with the core goals of longevity research: not just extending lifespan, but maximizing healthy years.
- Mechanism of Benefits: Why did the Ca-AKG mice fare better? The same study found concrete clues: Ca-AKG mice had higher levels of IL-10 (anti-inflammatory) and lower levels of pro-inflammatory cytokines in the blood. It’s likely that AKG quieted age-related inflammation and possibly affected the gut microbiome or other metabolic signals. The researchers proposed that AKG induces an anti-inflammatory state that in turn allows tissues to function better longer. In essence, Ca-AKG created a milieu inside the mice that was more youth-like at the molecular level.
- Healthspan Improvements: Beyond survival, AKG shows benefits in specific age-related conditions. A 2019 study in Nature reported that AKG supplementation in aged mice ameliorated osteoporosis, increasing bone mass and improving bone quality. The mechanism was traced to epigenetic effects in bone stem cells, as AKG reduced aging-associated histone methylation and boosted genes for bone formation. The same study noted that AKG (as part of a compound called OKG) helped undernourished elderly patients gain weight and heal wounds faster – indicating AKG’s role in protein metabolism and tissue repair. There is also evidence from model organisms like worms (C. elegans) that AKG extends lifespan by modulating metabolic and stress response pathways.
- Human Studies & Biological Age: The big question: does this translate to humans? While we don’t yet have long-term trials showing increased human lifespan (those would take decades), we do have some intriguing early data. In 2021, a small human study (42 individuals) examined a Ca-AKG supplement called Rejuvant. Over an average of 7 months, participants taking Rejuvant (a sustained-release Ca-AKG plus vitamins) saw an average reduction of 8 years in their biological age, as measured by DNA methylation “epigenetic clocks”. In other words, their epigenetic age (a biomarker of aging) decreased significantly, suggesting a potential age-reversal effect. This was not a placebo-controlled trial, so results must be viewed cautiously, but it’s encouraging. Both men and women saw reductions in biological age (men’s formula included vitamin A, women’s included vitamin D, but both had Ca-AKG). Most participants also reported feeling healthy with no major side effects. This study, while preliminary, aligns with the notion that Ca-AKG might slow or even modestly reverse aspects of biological aging in humans.
- Ongoing Research: AKG is drawing so much interest that multiple human trials are underway. One example is the ABLE study (Alpha-ketoglutarate and Biological Age in Middle-aged Adults), testing whether Ca-AKG supplementation can affect aging biomarkers in people. Results from such trials will shed more light on proper dosing, timing, and long-term safety in humans. As of 2025, Ca-AKG is considered a dietary supplement and is Generally Recognized As Safe (GRAS). It’s already used in certain medical foods and clinical settings (for example, AKG has been given safely to kidney dialysis patients to help with amino acid balance). This existing usage bolsters confidence that, at appropriate doses, AKG/Ca-AKG is safe for humans over extended periods.
Neutral vs. Preferred Form: It’s important to note that while plain AKG and Ca-AKG technically deliver the same molecule (AKG) to your body, all the evidence above is tied to Ca-AKG. The plain AKG likely offers some benefits – e.g. athletes have taken AKG (or AAKG) for performance and may get minor anti-fatigue benefits – but for the systemic, anti-aging effects, Ca-AKG is the form that consistently shows results. In comparative evaluations, Ca-AKG’s superior absorption and stability make it the clear winner for impacting longevity pathways. Next, we’ll provide a direct recommendation based on the findings.
AKG or Ca-AKG – Which Form Should You Choose?
In early sections, we kept the tone neutral while outlining both forms. Now it’s time for a verdict: if you are considering AKG for health or anti-aging, go with Calcium AKG (Ca-AKG). Here’s why:
- Greater Bioavailability = Greater Effect: The calcium-bound form ensures that the AKG actually reaches your bloodstream and cells in meaningful amounts. With Ca-AKG, you’re not “wasting” most of the dose in digestion. This means you’ll likely get more noticeable benefits (be it energy, recovery, or anti-aging effects) per dose of Ca-AKG compared to an equivalent dose of plain AKG.
- Backed by Research: The compelling longevity and healthspan results (lifespan extension in mice, reduced biological age in humans, etc.) were achieved with Ca-AKG. Those results are our best proxy for what to expect, and they set Ca-AKG apart as the form used by scientists for anti-aging investigation. Plain AKG, on the other hand, lacks such evidence in the anti-aging context.
- Stability and Ease of Use: Ca-AKG is generally provided in controlled-release capsules or tablets that are easy to take daily. It’s stable, often odorless/tasteless, and can be taken with or without food (though taking with a meal is often recommended). Pure AKG (alpha-ketoglutaric acid) would be acidic and potentially harsh on the stomach, whereas Ca-AKG is gentler (the calcium neutralizes the acid).
- Clinical Usage: Ca-AKG has seen use in human supplementation (even prior to anti-aging interest, it was used in medical scenarios). This gives it a track record for safety at recommended dosages. In contrast, taking raw AKG powder by itself is uncommon and not well-studied for long-term use.
In summary, Ca-AKG is the preferable form of AKG for longevity and wellness purposes. You’ll pay a bit more for Ca-AKG supplements than basic AKG powder, but the investment is likely worth it given the significantly higher efficacy. The neutral comparison comes down to this: both AKG and Ca-AKG provide the same molecule, but Ca-AKG is delivered in a way your body can actually use effectively.
Recommendation: Choose a reputable Ca-AKG supplement for your regimen. Start at a moderate dose (commonly 300–1000 mg of Ca-AKG daily, depending on the product) and see how you feel. Always pair it with healthy lifestyle practices – no supplement is a magic bullet, but Ca-AKG can be a powerful addition to a healthy diet, regular exercise, and possibly other longevity supplements (more on combinations in the FAQ).

FAQ – Frequently Asked Questions
Can I take AKG without calcium (just plain AKG)?
Technically yes – AKG is available in some supplements (sometimes as “alpha-ketoglutaric acid” or included in formulas like AAKG for sports). However, taking plain AKG is generally less effective for anti-aging goals. The free acid form is poorly absorbed (up to 80% may never reach your bloodstream). You’d likely get minimal benefits compared to the same dose of Ca-AKG. Moreover, pure AKG is acidic and might cause digestive upset or be unstable. Most experts recommend using a stabilized form of AKG. Calcium AKG (Ca-AKG) is the most popular because of its proven bioavailability and longevity research backing. Other salt forms like sodium AKG or magnesium AKG exist, but they are less common and not as well studied. In short, while you can take AKG without calcium, you’d be missing out on much of its potential. If you have an AKG powder, one trick is to take it with a mineral source (like with a calcium or magnesium supplement) to at least partially neutralize it. But for convenience and efficacy, opting for a Ca-AKG supplement is the superior choice.
What is the best time of day to take Ca-AKG?
There isn’t a universally “perfect” time, but many people take Ca-AKG in the morning. Since AKG plays a role in energy metabolism, taking it earlier in the day may align with your natural circadian rhythm for activity and might subtly boost daytime energy. Some find it mildly stimulating or notice improved workout endurance, which fits a morning or pre-afternoon timing. It’s often recommended to take Ca-AKG with food, for example with breakfast or lunch. Taking it with a meal can improve tolerance (though Ca-AKG is generally easy on the stomach) and may aid absorption as digestion is active. Morning dosing also mimics the pattern of fasting – AKG levels naturally rise during fasting/exercise, signaling the body to maintain muscle and repair (some users stack AKG in the morning of an intermittent fast). That said, there’s no hard rule – you could take it later in the day if it doesn’t energize you too much. Avoid very late evening just to be safe, as any potential energy/metabolic boost could interfere with sleep in sensitive individuals. Consistency is more important than timing: take it around the same time each day to keep levels steady. If you’re on a twice-daily high dose, morning and early afternoon would be logical spacing.
Are there any side effects or risks to taking Ca-AKG?
Ca-AKG is considered quite safe for healthy individuals. Research and user reports show no serious adverse effects at typical doses (300–1000 mg/day). Even higher doses (several grams per day) have been used in medical studies (e.g. up to 4.5 g daily for 3 years in a trial) without major issues. The body naturally produces and uses AKG, so it’s a familiar molecule. That said, here are some points to consider:
– Mild Side Effects: A small number of users report digestive upset, such as loose stool or mild nausea, especially if taking higher doses or on an empty stomach. This is likely due to the sudden influx of AKG altering gut metabolism. Taking with food usually resolves this. Start with a moderate dose to assess tolerance.
– Mineral Load: Ca-AKG contains calcium (usually a few hundred milligrams of calcium at most per dose). This isn’t a lot, but if you’re taking other calcium supplements or calcium-rich diet, be mindful of total intake. Excess calcium over time could potentially contribute to kidney stone risk in prone individuals. However, the calcium from a standard Ca-AKG dose is typically far below daily calcium supplement levels.
– Interactions/Medical Conditions: If you have kidney issues, be cautious – the kidneys filter out AKG and excess calcium. Those with chronic kidney disease or on dialysis should only use AKG under medical supervision (in fact, AKG has been studied in dialysis patients to help with amino acid balance, but individual conditions vary). Also, if you are on a calcium-restricted diet or have a history of calcium-oxalate kidney stones, consult your doctor. AKG itself might actually reduce calcium loss from bones in aging (it’s been noted to support bone mineral density), but each case is different.
– Medication Interactions: AKG is pretty benign, but it’s always good to be careful. If you are on prescription meds, especially those that alter metabolism, blood sugar, or blood pressure, check with a healthcare provider. The decodeage researchers note avoiding Ca-AKG if you’re on calcium channel blocker medications (a type of blood pressure med), just as a precaution. Also, those on blood thinners or with bleeding disorders should use caution, as with any supplement, although no specific clotting effects of AKG are known.
– Special Populations: Pregnant or breastfeeding women should be cautious as AKG hasn’t been studied in these groups – best to avoid or consult a doctor. Children/teens generally don’t need an AKG supplement (their bodies have plenty naturally). This supplement is really targeted at middle-aged and older adults or those with specific metabolic needs.
Overall, Ca-AKG has a strong safety profile. Many see it as comparable to taking an amino acid supplement in terms of risk. Listen to your body – if you experience any unusual symptoms after starting Ca-AKG (e.g., significant gastrointestinal distress, headache, or rash – all very rare), discontinue use and consult a healthcare professional. But the vast majority of people take Ca-AKG with no problems.
Can Ca-AKG be combined with other anti-aging supplements like NMN or resveratrol?
Yes, absolutely – and in fact this is quite common in the longevity community. Ca-AKG works via mechanisms that are largely complementary to popular anti-aging compounds like NMN (Nicotinamide Mononucleotide), NR (Nicotinamide Riboside), or resveratrol. Here’s how they might synergize:
– NMN/NR: These raise NAD⁺ levels in cells. AKG, as noted, also can support NAD⁺ and sirtuin activation by improving mitochondrial function. Using NMN (to boost NAD⁺ from the vitamin side) along with Ca-AKG (providing metabolic support that also results in higher NAD⁺/NADH ratio) could amplify NAD⁺-dependent pathways. Many biohackers report taking Ca-AKG each morning along with their NMN or NR. There’s no known negative interaction – if anything, AKG might make NAD⁺ utilization more efficient by keeping mitochondria in a youthful state.
– Resveratrol (or other polyphenols like quercetin): Resveratrol is famous for activating sirtuins (specifically SIRT1) and requires NAD⁺ to have effect. With Ca-AKG potentially raising NAD⁺ and even SIRT1 activity indirectly, it sets a stage where resveratrol can work optimally. Additionally, resveratrol and AKG both have anti-inflammatory and anti-oxidative effects, so they could collectively reduce oxidative stress and inflammation. There isn’t direct research on the combo, but mechanistically it makes sense as a longevity stack.
– Others: Ca-AKG is also stacked with things like vitamin D (for bone health synergy), collagen or glycine (since AKG aids collagen synthesis, adding the raw material like collagen peptide might support tissues), metformin (some experimental longevity enthusiasts add AKG to a protocol with metformin – no known issues there either, but that’s a medical gray area). Another up-and-coming combo is AKG with spermidine (an autophagy booster) – again, complementary pathways (AKG affects mTOR/AMPK, spermidine triggers autophagy, together they might enhance cellular cleanup and renewal).
Real-world anecdote: Dr. David Sinclair, a prominent longevity scientist, has mentioned he takes a regimen including NMN and resveratrol; while he hasn’t publicly confirmed taking Ca-AKG, his company’s supplement lineup (Tally Health’s vitality supplement) does include Ca-AKG alongside NAD boosters. This suggests experts see these as compatible.
When combining supplements, just be mindful of the total load on your body. It’s wise to introduce one new supplement at a time to gauge effects. Also, consider lifestyle: if you’re doing multiple longevity strategies (diet, exercise, cold exposure, etc.), adding a bunch of supplements like NMN, Ca-AKG, resveratrol simultaneously can make it hard to tell what’s doing what. But purely in terms of safety, Ca-AKG, NAD+ boosters, and resveratrol do not contraindicate each other. They target different yet interlinked aging processes, much like using multiple tools to tackle a complex problem. Stacking them might provide a broader spectrum of benefit – for example, Ca-AKG heavily targets metabolic and inflammatory aging, NMN targets cellular energy and DNA repair, and resveratrol targets stress response pathways. This multi-pronged approach is exactly what many longevity researchers hypothesize could yield the best results. Always keep your doctor in the loop if you’re on a serious longevity stack, especially if you have underlying health conditions, but for a healthy individual, this combo is generally regarded as safe and potentially synergistic.
By understanding the differences between AKG and Ca-AKG and how they work, you can make informed decisions in your quest for healthy aging. Remember that supplements like Ca-AKG are supplements – they work best alongside a healthy diet, regular exercise, stress management, and good sleep. But given the exciting research so far, Ca-AKG appears to be a valuable addition to the anti-aging toolkit, and its edge over regular AKG is clear.
