Product Description. Highly refined, pharmaceutical grade seal oil omega-3 capsules.

However, when phenylalanine is synthesized in the laboratory, half appears in the L-form and the other half in the D-form. These two compounds can also be synthesized individually, but it is more expensive to do so.
