Taurine is a sulfur-containing amino acid that occurs in small amounts in animal products like fish, meat and shellfish. In supplements, taurine is often added as a free amino acid due to its specific structure and availability.

L-glutamine is a non-essential amino acid found in many protein-rich foods, such as meat, eggs, dairy and legumes. It is often the first amino acid chosen in supplements because of how widely it is present in food.

L-tryptophan is an essential amino acid that is only available through food or supplements. It is found in seeds, soy, nuts, and animal proteins. It is often used in combination with other amino acids such as tyrosine and glutamine.

L-tyrosine is naturally present in dairy, fish, eggs, and legumes. It is an amino acid added individually to supplements or as part of amino acid complexes like Neuronyl Expert.

DL-phenylalanine is a mixture of D- and L-phenylalanine. L-phenylalanine is found in food and is an essential amino acid. The D-form does not occur in food but is synthetically added to supplements for the specific properties of the blend.

Active forms such as methylcobalamin and P-5-P are used in supplements because they are immediately available for absorption, without the need for further conversion. They are often chosen for formulas where direct absorption is desired.

Quatrefolic® is a patented, fourth-generation folic acid (5-MTHF) bound to glucosamine salt. It is often used because of its stability and solubility. This form does not occur in food, but has been developed for use in supplements.
