Vitamin B6, also called pyridoxine, is a water-soluble vitamin that belongs to the vitamin B complex. Vitamin B6 should be made sufficiently available on a daily basis through a high-quality diet or through supplementation. In addition, a healthy intestinal flora can also produce vitamin B6.

Vitamin B5, also called pantothenic acid, is a water-soluble vitamin that belongs to the vitamin B complex. Vitamin B5 is not stored in the body and must be made sufficiently available on a daily basis through a high-quality diet or through supplementation. In addition, a healthy intestinal flora can also produce vitamin B5. It is also essential to get enough vitamin C, as this activates the role of vitamin B5 in the body.

Vitamin B3, also called nictotinic acid, niacin or Inositol hexaniacinate, is a water-soluble vitamin that belongs to the vitamin B complex. Vitamin B3 is not stored in the body and must be made sufficiently available on a daily basis through a high-quality diet or through supplementation. But the body can also produce vitamin B3 itself using vitamins B1, B2 and B6 from the amino acid tryptophan, provided that these are sufficiently available.
