Premium natural ingredients with proven effects

Whey protein

Whey is a complete, high-quality protein containing all essential amino acids and contributes to the growth and maintenance of muscle mass.

Rice protein

Rice proteins are the product of the enzymatic fermentation of brown rice. The fermentation is carried out at low temperatures to preserve the best possible quality of the product. They have an almost complete amino acid profile, containing 19 amino acids, 9 of which are essential.

L-Carnitine

L-carnitine is an amino acid that is crucial for fat metabolism because it ensures that long-chain fatty acids are transported to the mitochondria where they are converted into energy.

Guarana

Guarana is a popular indigenous plant of the Amazon rainforest in Brazil. It contains guarana, which is almost identical to caffeine, except that it is absorbed much more slowly into the bloodstream and therefore has a longer lasting effect.

Vitamin C

Vitamin C is an important antioxidant that protects our cells from oxidative stress. It is necessary for the normal functioning of bones, teeth, cartilage, gums, skin and blood vessels.

B-complex

The B complex is a group of vitamins B1, B2, B6, B12, folic acid, pantothenic acid and niacin, which are important for our nervous system. In addition to their common function, each of the B vitamins has other important roles in our bodies. Vitamins B1 -5 and B12 work against fatigue and exhaustion. Folic acid is important for the normal functioning of the immune system. Vitamin B2 is important for the absorption and metabolism of iron and also acts as an antioxidant, protecting our cells from oxidative stress.
