About Life Extension – D L-Phenylalanine, 500mg – 100 vcaps

Life Extension D, L-Phenylalanine delivers 500 mg of this amino acid per vegetarian capsule across a convenient 100-capsule supply. Phenylalanine is an essential amino acid that the body cannot synthesise on its own and must obtain through diet or supplementation. It serves as a precursor to several important compounds involved in normal physiological function.

Each capsule is made with a vegetable cellulose shell, making this formula suitable for vegans and vegetarians. The clean formulation uses minimal excipients — vegetable stearate and microcrystalline cellulose — with no animal-derived ingredients, supporting a wide range of dietary preferences.

Life Extension recommends taking this product on an empty stomach in the morning and notes that it may be best utilised alongside the co-factors vitamins B6 and C. As with all Life Extension products, this supplement is manufactured to high quality standards.
