The main benefits of Ca-AKG

The use of a Ca-AKG supplement is associated with various processes in your body.

Supports energy production in cells

Ca-AKG is a component of the citric acid cycle. This is the natural process by which cells produce energy. It helps the mitochondria produce ATP. ATP is the direct fuel for your cells.

Contributes to the normal functioning of cells

Ca-AKG is involved in basic processes in the cell. These processes are necessary for your daily functioning and the stability of your cells.

Plays a role in processes related to healthy aging

Research shows that Ca-AKG is involved in energy metabolism and inflammation balance. These are factors that become important as your body ages. After all, your body’s own concentration of AKG can decrease as you get older. 

Supports the maintenance of physical function in animal research

Preclinical research in mice shows that Ca-AKG is associated with maintaining physical function for longer. Lower levels of chronic inflammation markers were also observed.

Contributes to maintaining normal bone processes

A human study in postmenopausal women indicates that calcium alpha-ketoglutarate is associated with a decrease in the bone resorption marker CTX. This points to a measurable inhibition of bone breakdown.

Ca-AKG versus AKG

You often see alpha-ketoglutarate (AKG) and calcium alpha-ketoglutarate (Ca-AKG) listed side by side. Ca-AKG is the stable form of this substance. In standard AKG, the molecules are not bound to a calcium atom.

With Ca-AKG, they are. This binding causes the substance to be absorbed more slowly in your intestines. As a result, it enters your bloodstream gradually. Calcium salts are often described in the literature as chemically more stable than the free form. There are indications that this can affect absorption and bioavailability, although there is limited direct comparative research on Ca-AKG versus AKG.

Research into Ca-AKG and bone health

The research from 2025 examined the relationship between calcium alpha-ketoglutarate (Ca-AKG) and bone health. The focus is on a human, double-blind study by Filip et al. from 2007, conducted in postmenopausal women. This research focused specifically on the process of bone remodelling, looking at the effect of Ca-AKG on the bone resorption marker CTX.

The study results show that supplementation with Ca-AKG led to a significant reduction in CTX levels compared with the control group. This indicates effective inhibition of bone resorption. The mechanism behind this is explained by the combination of calcium as an essential building material and alpha-ketoglutarate, which supports cellular processes. This compound supports how your body processes calcium. In this way, it offers natural support for your musculoskeletal system—especially when maintaining vital bones becomes essential.

Alpha-ketoglutarate and healthy aging

In this article from 2025, it is analysed how AKG contributes to healthy ageing by influencing cells’ energy metabolism and gene regulation. The research focuses specifically on the “healthspan”, the period during which the body remains free from age-related ailments.

Research in animal models (2020) showed that supplementation with Ca-AKG extends healthspan by reducing chronic inflammation and preserving physical functions for longer. In addition, early human data indicate a beneficial effect on biological age (DNA methylation), suggesting that cells continue to function “younger” at the molecular level.

The results suggest that AKG plays a strategic role in supporting essential cellular repair processes. This means Ca-AKG may help maintain natural vitality and support the body’s resilience during ageing.

Frequently asked questions about NMN

What does NMN do and what is it good for?

NMN is a promising molecule that has been extensively studied and is being researched for its potential benefits for healthy ageing and cellular health. NMN promotes the replenishment of NAD+ levels by acting as a direct precursor, which may affect energy production, cellular repair, and healthy metabolic functions.

Potential health benefits of NMN may include:

  • Support for healthy ageing and vitality: Research shows that NMN supplementation effectively increases NAD+ levels, which is important for supporting cellular health. Combined with regular physical activity, NMN helps slow the adverse effects of ageing and contributes to improved vitality and overall health.
  • NMN and insulin sensitivity: NMN increases NAD+ levels in the body, which is important for the function of enzymes that support energy balance and cellular health. This process may improve insulin sensitivity by optimizing the uptake and regulation of glucose in cells. As a result, NMN, according to research, may contribute to better blood sugar control and reduce the risk of insulin resistance, which is beneficial for overall metabolic health.
  • Support for blood pressure and vascular health: Research published in Nature Communications shows that NMN supplementation may help lower blood pressure and improve vascular health. By increasing NAD+ levels, NMN supports the flexibility and function of blood vessels, contributing to better circulation and healthier cardiovascular function.
  • Support for sleep quality and vitality: Research shows that NMN supplementation improves sleep quality in older adults and reduces sleepiness. Better sleep not only supports cognitive and physical performance, but also contributes to an improved quality of life and more healthy years of life. In addition, NMN was found to help reduce physical fatigue and improve lower-limb function, which is essential for an active lifestyle later in life.
  • Support for cardiovascular health: A scientific study shows that NMN supplementation may contribute to improving cardiovascular health. The study showed that NMN significantly improved blood vessel function by increasing NAD+ levels, which helps reduce inflammation and oxidative stress in the vessel walls. This highlights NMN’s potential to counter age-related decline in heart and vascular health. 

* It is important to remember that, although the research findings on NMN are promising, further studies are still needed to better understand the full scope of NMN’s health benefits and effectiveness.

What are the most notable studies on NMN?

Research has shown that NMN is a safe and effective way to increase NAD+ levels in the body. The clinical studies confirm that NMN is well tolerated and can have a positive impact on healthy ageing and vitality.

Another study shows that NMN supplementation can significantly improve gut health and slow age-related decline. In ageing mice, NMN extended lifespan and protected gut function by reducing inflammation, optimising gut bacteria, and supporting the integrity of gut tissue. These results suggest that NMN can be a valuable tool for healthy ageing and maintaining healthy gut function.

Another recent study examines how NMN supplementation can be personalised for better results. It focuses on variations in NAD+ levels between individuals and how these variations affect the effectiveness of NMN. The researchers aim to understand how NMN can best be tailored to personal needs. By adjusting the dosage to individual NAD+ levels, the supplement may be used even more effectively to support health and vitality. This research highlights the importance of a personalised approach when using NMN.

Buy NMN? When do you choose powder or capsules?

Are you convinced and want to buy an NMN supplement?

At EnduraVita, we offer NMN in both powder and capsule form, so you can choose what suits you best.

NMN powder is ideal for sublingual use (under the tongue) for fast absorption and precise dosing that you can weigh out yourself. You can also easily dissolve the powder in water or, for example, mix it into your yoghurt. NMN capsules are convenient at home and on the go, with a consistent dose.

We recommend trying both NMN powder and NMN capsules to find out what you prefer.

Is NMN dangerous?

More than 18 clinical studies have now been conducted, including by renowned institutions such as Harvard and other leading research centers worldwide. These studies show that NMN is safe as a supplement, even at daily doses of up to 1200 mg. It is likely that higher doses are also safe, but this still requires further research. NMN is a derivative of vitamin B3 and occurs naturally in the body and is produced by the body itself, meaning the body knows well how to handle this molecule.

Scientific research and user experiences also show that NMN as a supplement is well tolerated and has little to no side effects. It is a substance naturally present in the body that supports NAD+ levels, which is important for energy production and cellular health. 

This scientific study, for example, highlights the safety profiles of NMN when used at the tested dosages.

From this, the conclusion can be drawn that NMN is generally considered safe when used within the recommended dosages. 

Finally, NMN occurs naturally in foods such as broccoli, avocado, and edamame, and it is also found in breast milk, which underscores the importance of this substance in human metabolism.

Nevertheless, it is important to be cautious when starting a new supplement. Individual responses may vary, especially for people with specific health conditions or who are taking medication. Therefore, always consult a doctor before starting NMN, especially if you have doubts about possible interactions or risks. 

At EnduraVita, we uphold these high standards and guarantee the purity and reliability of our NMN products. To ensure this quality, we have every batch additionally tested by an independent laboratory. This ensures that our supplements are completely safe to use.

Can magnesium affect the number of connections in the brain?

There are indications that magnesium affects the structure of your brain. Experimental studies have shown that increasing the magnesium concentration in the brain can lead to an increase in synaptic structures. This occurs specifically in the hippocampus, the area responsible for your memory. In a study by Slutsky et al. (2010), this mechanism is described as a possible explanation for improved cognitive functions.

Why is magnesium important for balance in nerve cells?

Magnesium acts as a natural counterbalance to calcium. It regulates the influx of calcium into your nerve cells. This prevents neurons from becoming overstimulated. According to research by Vink & Nechifor (2011), this balance is necessary for the stability of your brain function.
