🧪 Formulation Notes

How it works: Biotin is a water-soluble vitamin necessary for cell growth, the production of fatty acids, and the metabolism of fats and amino acids.

It also plays key roles in gluconeogenesis and fatty acid synthesis, and is therefore critical for maintaining proper glucose and lipid metabolism. In addition, biotin is known to be important for healthy skin, hair and nails
