Nutricost Vitamin B2 (Riboflavin) 400mg, 120 Capsules - Gluten Free, Non-GMO

Great supplement! Easy to take, no side effects, and I’ve noticed better energy after use for migraine . Good quality and worth the price. Would buy again.

Great supplement. Good price. No side effects. Pill size if good. Digests well.

i use it every day, it makes me feel good like i was missing something that needed to inside me. great value for the money. Easy to absorb give me energy and my hair looks great. it lasted effect is great.

I've been using this brand for a long time.

Very good purchase. The product has great quality, is easy to use, and the price is worth it. I would definitely buy it again.

Works like a charm with my migraines however you will notice your urine will change color about a day or two after taking these.

I bought these to try and prevent migraines and tension headaches, and so far it seems to be working. I take one every morning and even though I’ve been under a lot of stress, haven’t had any headaches. I’ve bought other supplements from Nutricost and they’ve all been excellent.

Better than over the counter general vitamins

Ja, tut, was es kann oder soll. Persönlich keine Veränderung gemerkt, außer dass mein Urin recht gelb war. Keine Ahnung, ob sowas der Mensch braucht. Hätte ich vielleicht länger nehmen müssen.

Happy to have found this because B2 in this strength is very hard to find, and at such a reasonable price! Will definitely order again!

Very good, I like it very much.

Purchased after GP recommended B12 400mg for migraine prevention. Its near impossible in the UK to find this dose of B12 in one capsule (most places only do 100mg capsules at most). I was nervous buying "drugs" online but my migraine severity has reduced so I am sure it works! Coated capsules are easy to swallow and don't perish. Warning though- a side effect of a high dose of B12 is that your urine will quite literally turn neon. Like mountain dew. Do not be alarmed, this is normal, if not slightly unnerving the first time. This will return to normal within 48 hours of not having any.

Lo compré porque me lo aconsejaron por las migrañas perimenopáusicas, y, después de dos o tres meses, que es el tiempo que dicen tarda en hacer efecto, las migrañas se han reducido a la mínima expresión. Meo fosforito, eso sí, pero me es igual 😂😂. Cuando me llegó el bote me asusté porque creí que estaba en mal estado, pero no, es así, de un color vibrante 🤣. Volveré a comprar esta marca, no probé otras, pero esta me está gustando mucho. Por cierto, también tomo bisglicinato de magnesio, desde hace tiempo, pero por sí solo no me servía con el tema migrañoso.
