Quercetin shows promise for migraines
Quercetin Attenuates Nitroglycerin-Induced Migraine Headaches by Inhibiting Oxidative Stress and Inflammatory Mediators.
Moderate relevance to treatment efficacy
We explored how quercetin might alleviate migraine symptoms caused by nitroglycerin in rats. Over a week, we administered quercetin and examined its impact on behavior after inducing migraine pain.

The results were promising; quercetin significantly improved behavioral responses linked to migraine pain, showing a decrease in the severity of symptoms.

Its effectiveness appears to stem from quercetin's antioxidant and anti-inflammatory properties, suggesting it could be a helpful treatment for migraine relief.

Improved migraine relief
Great, it normalises sleep with regular intake of 2 capsules and significantly improves my migraines. The special effects kick in, and when I take the pills as usual, supplemented with magnesium, the migraine fades lightly within a couple of hours. Previously, I would be incapacitated for half a day. The frequency of attacks has decreased, likely aided by my consistent medicinal support. Regular magnesium intake eases both PMS and menstruation; I no longer feel irritable, and the first day can pass without painkillers. Chronic nasopharyngeal pain hardly worsens. While it’s tough to attribute all benefits solely to magnesium—given my omega-3 and other supplements—I believe it has played a part. With magnesium, lecithin, and protein, I truly noticed the positive effect of taking collagen. There were no allergic reactions or stomach issues, and the quality is superb with natural ingredients.
