THORNE - Riboflavin 5'-Phosphate - Bioactive Form of Vitamin B2 for Methylation Support* - 60 Capsules

Depending on what you’re taking it for it’s great. I take it to help with headaches and because I have issues absorbing b-vitamins. Fair warning it may make your urine neon yellow, which is safe and normal. Doesn’t hurt my stomach if I take with or without food.

Quality product

I can't take regular riboflavin for migraine prevention without having unwelcome symptoms. That doesn't happen with this form.

Thorne always has quality supplements. This riboflavin is no different, seems to work for me as intended. No complaints here.

Good product. Used after long illness and while recovering appetite for meat. Way too high priced. Health industry needs to adjust pricing for good health and maintenance items vs cosmetic and vanity products. With lots of boomers aging the companies can recoup R&D costs in quantity of sales.

I dump out the powder and titrate catered dosages for myself, and this powder works perfectly. Highly positive effects. Thank you for keeping such high quality standards during times of economic uncertainty.

Good quality

My doc prescribes this twice daily, and once daily for all other B vitamins. I like the extra brain and physical energy it provides, to help me with my methylation challenges.
