What we like: Algae oil supplements are a great alternative for folks who are plant-based or allergic to fish. Shapiro recommends this option from Orlo, citing it as a reliable brand that does third-party testing (although it’s unclear what lab does the testing, and there’s no seal on the packaging) and having a transparent label. The EPA and DHA come from Icelandic marine algae. The pills are also smaller than your standard fish oil capsule, making it easier to swallow.
