About Swanson – DL-Phenylalanine, 500mg – 100 caps

Swanson DL-Phenylalanine delivers 500 mg of this amino acid per capsule in a convenient, easy-to-swallow format.

Each bottle contains 100 capsules, offering up to a 100-day supply at one capsule per day, or a 50-day supply when taken twice daily as directed. Swanson is a long-established supplement brand committed to quality manufacturing standards, making this product a reliable choice for those seeking straightforward amino acid supplementation.

This product is formulated with a minimal list of excipients — microcrystalline cellulose and magnesium stearate — keeping the formula clean and focused on the active ingredient.
