How are we different?
Our vegan calcium alpha-ketoglutarate is produced without genetic engineering. The complex production process results in a raw material of the highest quality with a purity of over 99% and contains no additives.
For the capsule shells we use custom-made HPMC capsules that, unlike most other HPMC and pullulan capsules on the market, are 100% free from controversial additives such as carrageenans and PEG. We then package this product in environmentally friendly amber glass.
- Premium active ingredients in their purest form, sourced directly from the world’s best producers
- Select raw materials as the basis of all our formulations
- Our commitment: complete avoidance of all unnecessary additives, technical excipients and chemical extraction agents
- If additives are needed, valuable natural ingredients are prioritised
- Voluntary disclosure of every ingredient
- In-house production to achieve our high standards of purity and quality
- High-quality custom production of liquid products and (functional) foods as well as tablets by selected partners
- Packaging and encapsulation in Germany and the EU according to HACCP, GMP and ISO 22000:2018 standards
- Independent laboratory tests available on the product page
- Vegan capsule shells 100% without PEG or carrageenans
- Amber glass or high-quality, resealable bags featuring an aroma barrier to protect against oxidation and contamination used for packaging
- Storage in amber glass or product-specific, food-safe containers according to EC 10/2011
- Shipping boxes made from safe, sustainable materials
- All products 100% free from magnesium stearate, nanoparticles (no legal opportunism), titanium dioxide, genetic engineering and artificial colours and flavours
- Sugar or sweeteners deliberately added only when necessary, such as for functional or product-specific reasons
Effects
Effects
AKG is the nitrogen-free part of the amino acid glutamine and a natural byproduct of human metabolism. AKG is involved in the citrate cycle in the mitochondria and thus in energy production; if the citrate cycle is slowed down, the breakdown of fatty acids becomes inhibited and energy production is reduced. AKG also plays a role in the balance of nitrogen and ammonia as well as in amino acid biosynthesis (i.e., the formation of proteins). The proteinogenic amino acid L-glutamine is formed from AKG and ammonia. L-glutamine is mainly used up during sports, but also during stress and infections. Alpha-ketoglutarate alone or in combination with the amino acid arginine is particularly popular amongst athletes and bodybuilders. Organs that are particularly rich in AKG are the gastrointestinal tract, liver, skeletal muscles, heart, brain and fatty tissues. Levels of AKG decrease with age. Our innovative mixture of calcium and alpha-ketoglutarate ensures that alpha-ketoglutarate remains in the digestive tract for longer, thus increasing its bioavailability in the body.
