What is in Opti-EPA Liquid?

Each row as the label prints it, per serving of 5 ml. The capsule beside an amount places it among every product in the NIH database that lists the same ingredient: the bar is the middle half of their amounts, the line in it the median, the whiskers the 10th and 90th percentiles; the green tick is the FDA Daily Value and the red dashed tick the adult upper limit (IOM).

  • Its 888 mg of docosahexaenoic acid (filed by NIH under DHA) is higher than 96% of the 3,627 DHA products that print an amount; 152 list more.
