It's a good product, so far I'm happy with it. It smells okay, and I'm happy with the ingredients. I've tried other products from this brand, and they didn't cause any problems. I'll update my review once this product shows its effects. It's a good product, so far I'm happy with it. It smells okay, and I'm happy with the ingredients.

It has a high content of active ingredients, clean ingredients, and great value for money. The brand is trustworthy, and I keep repurchasing it. My family loves it.

I also like that the tablet can be divided and a smaller dose can be used.

I take it for migraines; it relieves throbbing headaches. I took it based on reviews. The size and quality of the tablets are fine, the taste is normal. Be healthy. The ingredients are natural. There are 90 pieces in a jar.

For mouth ulcers
Verified Purchase
I regularly get canker sores, so when I'm tired or have one, I take this along with vitamin C. I'd never experienced a niacin flush before, but it was clear that the color of my urine was affected by the supplement, so I started splitting the tablet in half and taking a quarter each, considering my deficiency and intake. (The round foam has a nice indentation so you can split it in half!) When I take it before bed, the pain from my canker sores improves a little. I wrote this review because I recently noticed a reduction in the duration of the pain after taking it.

It's really good, I can try it out slowly. The packaging is OK.

For mouth ulcers. If I don't use this, my mouth ulcers get all over me, which is especially bad before my period.
