### ⭐⭐⭐ Review
*by S***E on 13 November 2024*

I bought these vitamins after seeing an item on YouTube about B1 being good for decreasing swelling in the feet and/or legs. I have been taking them now for about week and can't see much difference but I will persevere. I assume it can't do any harm !!!
