Bonusan L-Tryptophan 500 Complex (60 capsules) is a formula with L-tryptophan, an essential amino acid. In addition to L-tryptophan, this supplement also contains various additional substances, such as vitamin B3, active B6, B12, folate, and a small amount of iron. Vegetarians in particular should make sure they get enough L-lysine through their diet. The capsules are easy to use: just one per day is sufficient.
Folate is the natural, active form of vitamin B11. Quatrefolic® is a patented, stable and directly usable variant of this form, in contrast to synthetic folic acid that first has to be converted.
Methylcobalamin is an active form of vitamin B12 that can be used directly in food supplements. This form is often chosen because of its stability and high biological availability.
Yes, this supplement contains a small amount of iron (2.1 mg per capsule), in the form of iron fumarate. This is a mild, well-tolerated form that is often used in food supplements.
L-tryptophan is an amino acid that belongs to the essential amino acids. This means that it is not produced by the body and must be obtained through diet or supplements.
