Reviews
Extremely convenient, humongous serving size
"I've been vegan for 13 years and need b-12 supplementation. This b-12 is insanely dosed. It's both odd and also reassuring. And there is no neon urine. I'm not sure, offhand, if that happens with vitamin B supps because of the 12 or some other b vitamin. (incidentally I also use nutrabio b3 and B6 and it doesn't happen with those either) So it seems to me that that means I'm absorbing more of it than if it looked like I was wizzing Lemon/Lime Powerade an hour after taking it"
So far, so good!
"First time buying this as a standalone product and not in a multivitamin. Was very happy to see this is not tue cyanocobalamin form of B12. That form wrecked my gut however this one from NB hasn’t done this to me. Starting to feel more energy."

The NUTRA BIO Vitamin B-12
"The NUTRA BIO Vitamin B-12 is an exceptional product. I have been using B-12 for a number of years given my mental health state. And, B-12 does in fact assist in Red Blood Cell production and I suffer from LARGE RED BLOOD cells based on my last three previous blood draws. The B-12 has improved my 'Mental State' and I will be using this product for the rest of my life. Please note: The B-12 provided by Nutra Bio is not the synthetic version of B-12 - it is the Methyl - not the Cyan version. Do the research. It is readily available."
Great product
"I really feel the cognitive boost in my performance. Certainly will purchase again."
Q&A
Frequently Asked Questions
What is NutraBio Vitamin B12?
NutraBio Vitamin B12 is a daily vitamin supplement delivering 2,000 mcg of methylcobalamin, the active form of Vitamin B12, in a single vegetable capsule. Each bottle contains 90 capsules, a three month supply. It is manufactured in NutraBio's own cGMP inspected facility in Middlesex, New Jersey, with every ingredient and amount fully disclosed on the label and no proprietary blends.
What does Vitamin B12 do for the body?
Vitamin B12 supports energy metabolism, healthy nervous system function, and red blood cell formation. It helps the body convert food into usable energy and helps maintain the myelin sheath that protects nerve cells. Because B12 is central to these processes, low levels commonly present as fatigue, mental fog, and low mood before other symptoms appear.
What is the difference between methylcobalamin and cyanocobalamin?
Methylcobalamin is the active, bioavailable form of Vitamin B12 that the body can use immediately with no conversion required. Cyanocobalamin is a synthetic form that must first be converted by the body before it can be used. NutraBio Vitamin B12 uses 2,000 mcg of methylcobalamin for that reason.
Who should take a Vitamin B12 supplement?
Vegetarians, vegans, and adults over fifty are the most likely to benefit, since Vitamin B12 occurs naturally almost exclusively in animal foods and absorption declines with age. People taking certain medications that affect stomach acid, and anyone experiencing persistent fatigue or mental fog, may also benefit from consistent daily B12 intake.
Is 2,000 mcg of Vitamin B12 too much?
No. Vitamin B12 is water soluble, meaning the body uses what it needs and clears the remainder. No tolerable upper intake level has been established for Vitamin B12. Higher serving sizes such as 2,000 mcg are commonly used because only a small percentage of oral B12 is absorbed. Consult a physician if you have a medical condition or take medication.
How should I take NutraBio Vitamin B12?
Take one capsule daily with or without food. Consistency matters more than timing, so take it at whatever point in the day you are most likely to remember. Each bottle of NutraBio Vitamin B12 contains 90 servings.
Is NutraBio Vitamin B12 vegan and free from allergens?
NutraBio Vitamin B12 is vegetarian and made without gluten, lactose, artificial colors, flavors, or sweeteners, using a hypromellose vegetable capsule. It is processed in a facility that also processes milk, eggs, and fish. Independent third party lab results for every batch are available at CheckMySupps.com.
