The verdict
Is Omega-6 Fatty Acids worth taking?
Most people already have too much omega-6, not too little. The goal is not to add more but to fix the ratio by reducing inflammatory linoleic acid from refined seed oils and where needed supplementing with GLA, the anti-inflammatory omega-6 form. Choose borage oil as the most concentrated GLA source. The most impactful first step is removing sunflower, soybean, corn, canola, and cottonseed oils from your kitchen.
What it does
What Omega-6 Fatty Acids does in the body
Cell membrane integrity, skin health, hormonal signaling, immune function, and nervous system support. The challenge with omega-6 is not deficiency but imbalance. Most adults consuming a modern processed diet are already getting 10 to 20 times more omega-6 than omega-3, creating a chronically pro-inflammatory state. The goal is not to supplement more omega-6 but to reduce inflammatory LA from refined seed oils and where relevant supplement with gamma-linolenic acid (GLA), the anti-inflammatory omega-6 form.
The evidence
What the research actually shows
The essential role of omega-6 in cellular function is well established. GLA specifically has strong evidence for reducing inflammation, improving skin conditions, and supporting hormonal balance. The broader omega-6 category is complicated by the fact that excessive LA from refined seed oils is one of the most well-documented drivers of chronic inflammation in the modern diet.
Food first
Getting Omega-6 Fatty Acids from food
Hemp seeds are the most balanced whole food omega-6 source. The most important food-first action for omega-6 is elimination rather than addition. Removing refined seed oils from cooking and replacing them with olive oil, avocado oil, coconut oil, and grass-fed butter addresses the inflammatory omega imbalance more effectively than any supplement.
