Review: Awesome - Works for me and mild common headaches sometimes combine with coq10 sometimes not as that's more expensive and slightly stimulating. Very good bulk deal. I wish bag sealed more tightly though be very cautious about that as the stains are similar to turmeric stains, but not sure if they are easier to get out I wouldn't risk it. Not a strong taste maybe slightly bitter.
Review: Always great products - I try to get as many of my supplements from this company as I can. They are always good quality, competitively priced, and seem to be adding new products all the time. After ordering another product I was offered the opportunity to receive a product of my choice in exchange for my honest review. I greatly appreciate this as well as I get the opportunity to try something new with the risk of feeling it was money down the drain if it's no good, or just no good for me. Truthfully I never really fear this with this company, I've been using their products for years and will continue to do so. It's difficult to say whether this specific product is doing a whole lot as it was prescribed by my neurologist at a dosage of 400mg daily as part of a migraine reduction regimen. What I can say is most B vits nearly gag me they smell so bad just opening the bottle, and it takes a LOT to kick this in for me. I was a little worried about getting powdered B's fearing it would ruin my AM cocktail but this one is practically odorless and changed nothing about the taste of my drink so I'm pretty happy :)

### ⭐⭐⭐⭐⭐ Did not buy as a supplement, though I did save some for that use.
*by C***M on March 17, 2023*

It can be added to frosting or drinks in small amounts for interesting effect during a black-light party! But my use was VERY different.... I had a leak in my home well water pump system that I needed to trace. ALL commercial water tracing products had ingestion warnings / not fit for human consumption. Fortunately, riboflavin strongly fluoresces under UV light, is consumable even in large doses, and water soluble. That last part is most important, because not only will it easily mix in my water system, any amount ingested that the body cannot use will be easily expelled! I added about 1/2 the package to my water system, waited till nightfall, then easily found the source of my leak & the 2x increased electricity bill that let me know something was wrong... Although the main leak could be seen during daytime (as seen in attached photo), there were 2 smaller leaks that I wasn't able to see till night time & would never have found without the intense UV glow of the riboflavin. ONLY downside, riboflavin is VERY bitter. Also I had to let it go into my water heater because I didn't know if it was hot or cold line that was leaking.... It's already completely flushed out of the cold water lines, but still tints the hot water.
