Can fish oil and vitamins lower a harmful blood chemical?
A combination of omega-3 fatty acids, folic acid and B-group vitamins is superior at lowering homocysteine than omega-3 alone: A meta-analysis.

Surprising Findings
Omega-3 alone had a statistically significant but clinically tiny effect on homocysteine (1.09 μmol/L drop), while B-vitamins alone are known to drop it by 1.5–4.5 μmol/L.
People assume omega-3 is a major player in homocysteine control — but the data shows B-vitamins are the real powerhouse, and omega-3 is just a supporting actor.
Practical Takeaways
If you're taking omega-3 for heart health, consider adding B-vitamins and folic acid — they boost the homocysteine-lowering effect.

To keep your brain working its best, you need enough omega-3s (found in fish and nuts) and low levels of a substance called homocysteine, which means you're getting enough B vitamins from your diet.
Taking omega-3s along with folic acid and B vitamins lowers a substance in your blood called homocysteine more than just omega-3s alone—like getting a little extra boost from the combo.
Taking omega-3s and B-vitamins can lower a substance in your blood called homocysteine, but how much it goes down depends on how much you take, how long you take it, and how healthy you were to begin with.
Taking omega-3s and B-vitamins can lower a substance in your blood called homocysteine, but that doesn't mean you're any less likely to have a heart problem or brain disease — the research doesn't show a connection.
Taking omega-3 supplements can lower a substance in your blood called homocysteine, which is linked to heart disease. If you also take folic acid and B6/B12 vitamins along with omega-3s, the drop in homocysteine is even bigger — so the combo works better than omega-3s alone.
