WHAT IT DOES
The richest natural source of GLA, an anti-inflammatory omega-6 that actually helps reduce inflammation instead of causing it.
🏆
2
DOES IT WORK?
Interesting omega-6 that breaks the mold. Borage oil contains 20-26% GLA (gamma-linolenic acid), which gets converted to DGLA, an anti-inflammatory compound. Decent evidence for rheumatoid arthritis and skin conditions. Not a must-have, but genuinely useful for the right person.
