Riboflavin 5'-Phosphate, 60 Capsules | Bioactive Vitamin B2 for Energy & Methylation Support, Contains B Vitamins

Excellent quality, as expected from Thorne. This active form of B2 is easy to tolerate and feels noticeably more effective than standard riboflavin. Clean ingredients, no unnecessary fillers, and capsules are easy to swallow. A premium supplement that feels well thought out and reliable. Would definitely repurchase. Strong supplement, don't mix with complex

Seems useful

I love lots of products from Throne. they always produce the best direct form of vitamins. same to this. its vitamin b2 but in Active, direct form of R5P. and i believe the quality is excellent too. i don't know why but it's difficult to find the active form of this b2 in the UK easily. and only downside is the price. too expensive. there are many normal b2 (not in active form) out there in 1/3 price of this. and you only receive 60 caps per bottle so have to say, this is one expensive product but i have to continually buy it because of my daughter needs this every day for her condition..

I like it very much. Very good quality.

Exellent product ,as described and arrived promptly. I would recommend this product as it has helped me regain my health.

it's fully activated, your body just absorves it as it is...it's one of many I use in a treatment, let's give it time to work...more upfront I will share any news.

Just as with tetrahydrofolate, I experienced no difference in taking it, neither good nor bad (yes, I did have reasons to believe that they would exert some effect).Of course, this is not to do with the quality of the vitamin.

Good

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.

Great product! I’ve been using almost a year!

Like buying my vitamins from Thorne this is not the first time for me. The supplement gives me energy. It’s a great value for the money. The pill is easy to swallow. It’s not a very big pill.

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.
