Great

High-quality ingredients, convenient packaging, neutral taste. The results are good. I had a problem with cracks in the corners of my lips, and nothing else helped. This product works perfectly, and it's all gone away.

B2 helps convert carbohydrates, fats, and proteins into energy, and is also involved in the production of ATP, the main energy carrier in cells. This supplement is of high quality.

Energy for metabolism!

Verified Purchase

I take this vitamin B2 in a high dose to support energy metabolism. The tablets are small and easy to swallow. I noticed an improvement in my skin condition after starting to take it—inflammation and redness have decreased. I also felt a boost of energy. KAL is a reliable brand with a good reputation.

first time using this b2

Verified Purchase

This is my first time using this version of b2. It doesn't have a strong b2 odor like the other b2 ive tried previously carry. Not sure if it's a good thing? But I think overall it's not too bad since the tablets are kinda easy to swallow which is important for me.

Super

Verified Purchase

The product is excellent quality. The ingredients are well-chosen. It didn't cause any allergies or other adverse reactions. The packaging is large, so it will last a long time. The capsules are medium-sized. The flavor is neutral. Fast and undamaged delivery. The formula contains only beneficial and natural ingredients, as well as folic acid. Bowel function and metabolism have improved. The first changes are noticeable within a week. My nervous system functions better, and I'm less nervous. I have no doubt about the product's effectiveness.

Verified Purchase

It has no unpleasant taste or smell. It's easy to take. I haven't noticed any side effects. I take it for mental and physical balance, so there may be some benefit. The main thing is to feel GOOD, and everything else will come or fall.
