A formula you can feel working

Hyaluronic acid is a polysaccharide the body produces itself: a long chain of thousands of repeating disaccharide units. A molecular weight above 1 MDa means a chain of more than two thousand such units: in Nutrihyl® it is kept long rather than broken into short fragments. Sodium hyaluronate is the same molecule in the form of its sodium salt, stable in aqueous solution. One serving contains 120 mg of hyaluronic acid, featuring Nutrihyl®.

Vitamin C (ascorbic acid) is essential for the body: it cannot be synthesised and must come in daily. It acts as an antioxidant, contributing to the protection of cells from oxidative stress, and takes part in normal collagen formation — for the normal function of skin and bones. It contributes to the reduction of tiredness and fatigue. One serving contains 330 mg of vitamin C.

— a water-soluble B vitamin (B7). The body gets it from food: eggs, nuts, legumes and liver are rich in biotin. It contributes to the maintenance of normal skin. One serving contains 10 µg of biotin.

— a non-essential amino acid: the body makes it from serine. In the collagen triple helix the three chains are packed so tightly that only the smallest side chain fits inside, which is why every third link in collagen is glycine. It is also one of the three amino acids of glutathione, a compound every cell in the body makes on its own. One serving contains 460 mg of glycine.

— one of the nine essential amino acids. In cereal proteins such as wheat, rice and maize, lysine is the limiting amino acid: it is the one in shortest supply relative to the body's needs. In collagen and elastin, lysine residues form cross-links between the chains, and these cross-links bind the fibres into a strong network. One serving contains 360 mg of L-lysine hydrochloride, of which 288 mg is lysine itself.

— a non-essential amino acid: the body makes it from glutamic acid, and among foods it is most abundant in gelatin, meat and dairy. Together with hydroxyproline it makes up about a quarter of all amino acid residues in collagen. The body does not build ready-made hydroxyproline into protein: it is formed from proline inside the collagen chain, in a reaction that requires vitamin C. One serving contains 460 mg of proline.

— the body produces it from pyruvate, an intermediate of glucose metabolism. In collagen, alanine accounts for about a tenth of the residues. Between muscle and liver it works as a nitrogen carrier in the glucose-alanine cycle, one of the basic pathways of metabolism. One serving contains 360 mg of L-alanine.

Zinc is an essential trace element, a cofactor for hundreds of enzymes. It contributes to the protection of cells from oxidative stress and the maintenance of normal skin, bones, nails and vision. Here it comes as bisglycinate — bound to the amino acid glycine. One serving contains 3 mg of zinc.

— takes part in key processes: from connective tissue formation to antioxidant defence. It activates MnSOD — the mitochondria's own antioxidant enzyme that neutralises free radicals. It contributes to the maintenance of normal bones. Manganese is not produced by the body, so it has to come in regularly with food or supplements. One serving contains 0.4 mg of manganese.

— the bisglycinate form of copper: the mineral is bound to the amino acid glycine, which gives good bioavailability. Copper contributes to the protection of cells from oxidative stress and to the maintenance of normal connective tissues. One serving contains 0.2 mg of copper.
