I love b2, and so do some harmful lil bugs in my gut, apparently. when I take it orally I get skin issues and bloating, and it sucks a--. same thing with P5P, and I love both vitamins so much. now I've got one that I can dissolve under my tongue and straight into my system and I am rather stoked. in fact there might be tears in my eyes when I try it, there just might - energy support is a really emotional thing for me, you know? My mitochondria are sad. this unsads them. that's all
I'm sure the product works well, but for some reason taking it either sublingually or orally immediately caused extreme nausea, which hasn't happened with other FMN products I've tried before. The quality isn't bad per se, but the mint flavor also makes the taste worse than if the ingredient alone was used (it has a bitter/sour flavor, which combines rather badly with the mint flavoring).
