Eczema, Cheilitis, and Dermatitis relief!!
I had been suffering from a random flare up of eczema and angular cheilitis (perleche) for almost 2 months. I went to a dermatologist and received steroid cremes and anti-fungal creams, which after almost a month of applying, barely helped. I was frustrated that the doctor didn't take time to understand the cause of the flare up rather than just treating it, so I did my own research. It turns out people with Eczema naturally are B2 deficient, and B2 helps with dermatitis and cheilitis. Within taking this vitamin for 3 days, my lips finally return to their normal soft feeling, my angular cheilitis healed, and my dermatitis subsided. I can't recommend trying this enough!

Helps Reduce Frequency of Migraines
I've been taking your Vitamin B-2 for at least 2 years. I have frequent migraines, and my doctor found some research that determined the following combination to be effective in reducing the frequency of migraines: 400 mg of B-2 and 300 mg of
Co-Q 10 daily. It has made a big difference for me, and I'm truly grateful.

I have used this for many years to aid in my care of migraine headaches. It is just one of the ills to help me. If IK stay on meds this does seem to help. I do recommend B-2.

B2 is the most essential part of my regime for migraines....without it there is a very definite difference.

I purchased this when I found the 300mg B-1. My doctor has advised me to take several of the Vitamin B's, but at higher doseages, instead of just a plain B-Complex vitamin. I'm so happy to have found these products.

Part of the B-Complex
I took 2 tablets for about 6 months, when I was taking B2, B6, and Methyl B12. I only stopped because I started taking a multi-vitamin that included B2 in it and didn't want to risk taking too much. I continued and still take the Methyl B12, as that is a reliable standby, but treated the B2 and B6 with far more caution. Regardless, the B2 is solid. I try out new GNC products to find out which ones work better for me. As an insulin-dependent diabetic, I've given up on food as my primary means of sustenance, in favor of supplements. Over the past 3 years, i've proved to myself that, for a diabetic, they work to perfection!!
