Omega / Fatty Acid supplements

Omega-3 fatty acids for cardiovascular and brain health.

3 supplements in this category

Fish Oil (Omega-3 EPA/DHA)
Anti-inflammatory fatty acids essential for brain, heart, and joints. Look for IFOS-certified brands; rancid oils undo benefits.
Dose: 1–3 g combined EPA+DHA daily
Krill Oil
Phospholipid-bound omega-3s with included astaxanthin. Better absorbed per gram than fish oil but ~3× the price for same EPA/DHA.
Dose: 1–2 g daily (≈ 0.3 g EPA+DHA)
Algae Omega-3
Direct vegan source of DHA (and increasingly EPA). Bypasses ALA-to-DHA conversion, which is poor in most adults.
Dose: 500–1000 mg combined EPA+DHA
