NOW Vitamin B2 Riboflavin 100 mg (100 Capsules)

SKU: NOW80447

Essential B vitamin that supports cellular energy and metabolism

What It Does

Riboflavin supports your body's energy production at the cellular level. This essential B vitamin helps convert the food you eat into energy your cells can actually use. Unlike many B vitamins that work together, B2 has specific roles in red blood cell function and brain health.

Why It Works

  • CELLULAR ENERGY: Acts as a coenzyme in energy metabolism, helping convert nutrients into ATP.
  • RED BLOOD CELLS: Supports healthy red blood cell formation and function.
  • BRAIN SUPPORT: Contributes to normal neurological function and mental clarity.

What's Inside

For migraine prevention

Several studies have shown that B2 can help to prevent migraines. I can’t say for sure if it is helping in that regard yet but will do whatever I can to decrease frequency. This is a good price and a brand that I trust.

Prescribed by a Neurologist for migraine headaches.

I suffered migraines more often/significantly when I entered menopause. The Neurologist had MRI results and concluded that the issue was more physiological because when women are in menopause their natural B2 is reduced. He prescribed B2, 100mg 4 times per day. The migraines reduced both in frequency and pressure over a few months and are now non existent. I tried other brands in the beginning but NOW was the one which acted faster and there are no side effects. Friends who suffered from migraines asked how I got these results, I advised them, they spoke to their Doctors and are now reaping the same great results that I did. One friend was taking the B2, 400mg all at once but when she heard that I did it breakfast, lunch, dinner, bed she changed her routine and got the relief that I did.
