Bought for migraines on neurologists recommendation=400mg per day

neurologist recommended i take B2 tabs for migraines. dosage is 400mg daily. no brand makes tabs in more than 100mg. So it means I take 4tabs daily (2×am/pm). so you go thru a bottle fast! this brand, with 90tabs has more tabs than the other brands I can purchase in local shops. plus 1/3 cheaper than local shops. 90tabs last 22days Really like this brand. Probably the cheapest vitamin brand on i-Herb & can't buy in my local shops!

Great

Natural factors are one of my favorite supplements. It works great, the quality is great and the price is good. The effect for metabolism and nervous system is very good. The taste is neutral. The size, package, ingredient, composition is as mentioned is description. When it starts working it fills with energy. But you have to know if you have deficits of Vitamin B2 before use

I bought this B2 to support my daily health. The tablets are not too big, so taking them is very easy. There is no bad taste at all when I swallow them. The package came well sealed and everything inside was clean. It is a very good quality product for a reasonable price.

I don't know if it is a placibo effect but saw the benefits from the first use. Good quality product, good ingredients. The package will be enough for 3 months, so happy with size for the money I paid. Will comment later on the potency of the product, but overall I can reccomend.

Nice

I really like these Stridex pads. They are very easy to use and gentle on the skin. The scent is light and not strong, which I appreciate. The quality is great, and the pads are soft but effective in cleaning the skin and helping with acne. The size of the pads is perfect and one pad is enough for the whole face. I think this product is suitable for teens and adults of different ages. Overall, it’s a great product and I would definitely recommend it.

I started taking this riboflavin on the recommendation of my doctor for managing occasional migraines. The tablets are small and easy to swallow, which makes them a hassle-free part of my daily routine. I've noticed a significant decrease in both the frequency and intensity of my headaches since I began. It's a simple, single-ingredient supplement that has made a real difference in my quality of life.

great tablet form of b2

Straightforward B2. 100 mg is a lot, but since it’s a tablet you can snap it for smaller doses. Works fine, cheap. Most probably outperforms 'activated' forms of b2 if given with food.
