A friend recommended these to me, and my energy has improved so much. I literally can make it through my 8 hour shift at work, without feeling like I need 5 cups of coffee. So glad I tried this out.

Due to a chronic condition, my B levels are always low. Since starting this supplement about a year ago, my lab work shows my levels are consistently within normal range. I feel better and have more energy!

My diet is vegan, mostly raw. My body was hurting so bad for days, I could barely move. I took only one of these as soon as I received the bottle, and the next day I could move again without pain. I would say they absorb very well, since one capsule worked for me overnight.

The missing piece.

A diet of healthy whole foods may be rich in most vitamins, but B12 is the only nutrient that can’t be supplied from a plant-based lifestyle alone. Available naturally in animal sources, B12 plays an important role in supporting the metabolic activity of the brain and nervous system. We created a 100% vegan option that maximizes absorption without compromising preference, lifestyle or wellness routines.* It’s an easy, efficient way to support the mind, mood and more.*

Suggested Use

Each veggie capsule contains 1500 mcg of vitamin B12. Take one capsule daily with food.
