One of the best values on the market
24karats—December 27, 2025
Nature Made is one of my preferred vitamin brands because their vitamins are one of the best values on the market. I take B1 at the recommendation of my podiatrist because I am older and diabetic, so peripheral neuropathy is potential problem for me. This is one of the supplements that is recommended for the prevention of peripheral neuropathy. I have been taking this supplement for years and have experienced no side effects. As for the efficacy, I have to trust the opinion of my doctors, and they seem to be quite satisfied. Meanwhile, I am healthy so I will continue to use this supplement. Read more
