The NOW Foods Vitamin B-2 (Riboflavin) 100 mg has been really helpful for supporting energy production. I’ve noticed a boost in my overall energy and feel more alert throughout the day.m It has helped with the wife's TBI as well. The tablets are easy to take, and the price is very reasonable compared to other brands. Definitely a solid choice if you’re looking for a reliable B-vitamin supplement. Read more
