Algal DHA
Plant-based DHA omega-3 derived from microalgae, the original source fish get their DHA from.
Also known as: Algae-Derived DHA • Vegan DHA • Schizochytrium DHA
Overview
Algal DHA is docosahexaenoic acid derived from microalgae (Schizochytrium or Crypthecodinium). Since fish obtain DHA by consuming algae, algal DHA goes directly to the source. It provides the same brain, eye, and cardiovascular benefits as fish-derived DHA but is suitable for vegetarians and vegans.
