Good news for vegetarians and vegans who find it challenging to get an effective dose of long-chain omega-3s found in fatty fish and fish oil supplements. A recent study in The Journal of Nutrition reported that algae-sourced DHA supplements may reduce triglycerides and boost heart health by increasing HDL (good) cholesterol.

Though the DHA supplements also slightly raised LDL (bad) cholesterol, researchers noted these were generally large particles, which are considered less harmful than small, dense particles. The net effect is likely to reduce cardiovascular disease risk.
