Nature's Way Riboflavin Vitamin B2, Supports Cellular Energy Production*, High Potency Riboflavin, 100 mg per Serving, 100 Capsules (Packaging May Vary)

Just don't take it at night, it's like caffeine. Good morning B-vitamin and I think it's doable for most people on an empty stomach. Though last time I did that I became extremely hungry and my mind was going going going. It'll Rev up your brain a bit when had with a meal. It's no miracle though. Other than that don't know much more about it at the moment. It's a nice dose, actually pretty damn high for riboflavin, whereas 500 Mills is considered high for B5 and B6, etc. I plan to buy "B-Right" by Jarrow soon, and that'll cover me with this supp. I was wanting to get the highest of each B vitamin and so was buying separate 500mg supplements of everything, but now I don't feel comfortable taking such high doses. You end up having to split them up between the days of the week. Your body and especially your liver can only handle so much at once. So it's best to choose a moderate dose of everything (including choline, inositol, and PABA) together, that way you get some of everything daily and you don't have to fear that that 500 Mills of B5 plus 500 Mills of B6 plus 500 Mills of B1 will end of paralyzing you or some s***.

I purchase and use this vitamins constantly. They are a great vitamin and I love the easy to open lids. Will definitely continue to purchase these vitamins on Amazon. The price is amazing.

I've been taking a migraine rx for years, first Imitrex (sp?) but that made me super nauseous! So now I take Zomig which only makes me a tiny bit nauseous for a few minutes. However it's spendy since I was getting a migraine every other to every few days. And without an Rx they stick around for about 3 days and are pretty much debilitating. I even tried botox for them but the migraines figured that out and moved down into my eye socket away from the botox. Sigh. And no OTC meds will help if one has already started. My doctor heard that B2 could help with migraines and suggested I take it daily. OMG! After about a week and a half they were gone! Seriously it was like a miracle! I'd had them since I was a child and nothing ever worked to prevent them. Not that this is perfect, they do break through about once every few months, especially if I forget to take the B2 one day or when I watch a 3D movie. I just keep the Zomig on hand for that. I am so grateful for this miracle I had to share and hope it helps someone else with a similar situation! Tried some other brands but this one seems to deliver the best results. Others im guessing the potency isnt as good as I had too many breakthroughs. Now if I could only find a similar cure for acne...

I liked them

I started taking 400mg of B2 a day at my doctor's recommendation for migraine prevention, because I can't be some of the more traditional options for a variety of reasons. I started taking these the same time as I started taking a hormone for migraine prevention, too, so I can't say with any confidence which is the main cause of the improvement (or if it's a combination), but I do know that I have had a DRASTIC reduction in my migraines since I started taking four of these a day regularly; I get about a third as many as before. It's a lot of pills to take a day, but they are inexpensive on Amazon and thankfully there is a subscribe & save. I do wish these were gelatin-free, but it's a minor price to pay for migraine relief. My mother recently started taking these for migraines, as well, and has also had positive results. If you're a migraine sufferer, you know that ANYthing is worth a try, so I'd say go for this and see if it helps you, too! I noticed a change within two weeks. The only side effect is that it turns your pee fluorescent :) Oh well--helps me keep track of how hydrated I am!

Product arrived safely & on-time. No problems whatsoever. Taking this supplement according to DFU. Happy customer.

Most amazing lil blue pills I have ever take'n in my life!! They make me feel like I'm floating in the air wrapped up in fluffy clouds
