An excellent product

Posted by Reviewer2358927 on Dec 23, 2008

These sublingual tablets can prevent a migraine if you take it just when you feel one coming on. Even if the headache had begun it helped a great deal. Not bad tasting, all things considered.

Nasty tasting + stains teeth/gums yellow

Posted by Reviewer2945962 on Jan 25, 2011

On my way out the door I popped one of these under my tongue thinking I'd let it dissolve while I ran some errands. I could only stand the horrible taste for about a minute (if that). Went to the bathroom sink to spit it out and noticed in the mirror that my teeth and gums were now BRIGHT YELLOW. FYI, if you've ever taken a B complex vitamin before, B2 is the one that turns your pee yellow. I forgot about that. Good thing these tablets are so horrible tasting or I'd have gone out looking like my teeth were rotting out of my head. It came off my teeth after some rinsing, but my gums looked yellow for a while longer. Maybe these tablets do actually work, but the taste and staining are so off-putting that I'll never know. Kudos to those other reviewers who were able to keep these things in their mouth longer than I did. I just wish one of them had said something about the yellow staining and nasty taste in their review. They could've saved me a few $$.

Fast Absorption Helps Eyes & Skin

Posted by Reviewer2600891 on Dec 05, 2010

I have had red sore itchy eyes and they heal overnight with this sublingual B-2. Also, wrinkles in skin are lessened with one use. I even take a B-complex tablet daily, but seem to need extra B-2. I place one (or two) under my tongue and notice the effects immediately. Not fond of the mint flavor but it dissipates quickly. Like the orange flavor better, but it is not available. Great price, 2X as much at local store. iherb is the BEST!

Could be helpful.

Flavin Mononucleotide is needed by the enzyme pyridoxine 5'-phosphate oxidase to convert vitamin B6 into its active form of pyridoxal 5'-phosphate (aka p5p). This product could be helpful for people in which this particular enzyme may be under functioning.

Activated & Bio-avaliable B2

Posted by Reviewer2648337 on Apr 28, 2014

must have B2 supplement - I've noticed a difference since this is a form the body can use directly. Other forms are not converted to something the body can use.

For Migraine

Posted by 5109157552070576586 on Oct 20, 2014

Several of my family members have occasional migraines. We didn't have any migraine emergencies recently, so I will give an update after we actually used it. Until know, I give it 5 stars in advance.
