Is omega-6 bad for you?

No, it's essential. But it's over-consumed. The average Western diet has a 15:1 or 20:1 ratio of omega-6 to omega-3. A healthy ratio is closer to 4:1 or less.

Should I take an omega-6 supplement?

Almost certainly no. Focus on reducing your intake from processed seed oils and increasing your omega-3 intake from fatty fish.

What's the deal with GLA or evening primrose oil?

GLA is a specific type of omega-6 that can have anti-inflammatory effects. It's the one exception where supplementing might make sense for targeted issues like eczema or PMS.

What it does

It's a structural fat for cell membranes and a precursor to signaling molecules that control inflammation. It can be either pro-inflammatory or anti-inflammatory. The balance is what matters.

Does it work?

No. 7/10. For general health, you're almost certainly getting too much from food. The exception is specific forms like GLA (from Evening Primrose Oil) for issues like eczema, but that's a targeted use case.

Click through to the studies bar for the evidence base.

How much

Don't supplement for general health. Get it from whole foods like nuts and seeds. For specific GLA supplements, doses are often around 500-1000mg daily. Consult a doctor.

See the dosing guide below.

Cost

Cheap. $20-35/month for common sources like Evening Primrose Oil. But cheap doesn't mean you need it. Save your money and buy some quality fish oil instead.

Compare formats before buying.

First 24 hours

Absolutely nothing. This is about changing the fatty acid composition of your cells, which takes weeks to months.

Some ingredients build up over weeks. Others act fast.

After weeks

For a targeted GLA user, potentially improved skin health or fewer PMS symptoms. For someone taking a general omega-6 supplement, potentially a worse omega-3 to omega-6 ratio and more low-grade inflammation.

The compound effect of consistent dosing.

Safety

Generally safe, but it's all about context. The problem isn't the fat itself, it's the massive quantities found in processed foods and seed oils, which throws your whole system out of balance.

Check the cautions section if you have a pre-existing condition.

How it feels

You won't feel it. This isn't a stimulant or a relaxant. It's a foundational nutrient that works silently in the background. The goal is balance, not a sensation.

Some ingredients you feel. Others just work in the background.

Quick answers · dose curve
Forms · food sources

What foods are highest in omega-6?

Soybean oil, corn oil, safflower oil, sunflower oil. This means most restaurant food, fried food, and processed snacks are loaded with it.

Can I just take more omega-3 to balance it out?

That definitely helps, but reducing your omega-6 intake is the other half of the equation. You can't just out-supplement a diet high in processed oils.

Will this make me gain weight?

No. Like any fat, it contains calories, but supplementing with a softgel or two won't impact your weight.

Bottom line

0.5g is the number.

Most research uses 0.5g daily. Below 0.3g, you're probably wasting money. Above 1.5g, no extra benefit. The curve plateaus. Safe upper limit ~ 3.0g.

Most processed foods. You don't need to try. A single order of fries or a salad with commercial dressing gives you a massive dose. The challenge isn't getting enough, it's avoiding it.
