Product Information



NOW® Ultra B-12
Cellular Energy Boost
5,000 mcg of B-12 per Teaspoon
3 Forms of B-12 for maximum Utilization
Complete liquid B-Complex
High in Folic Acid 800 mcg

Vitamin B-12 is a water-soluble vitamin necessary for the maintenance of a healthy nervous system for the metabolic utilization of fats and proteins. Vitamin B-12 is also essential for the synthesis of DNA during cell division and therefore is especially important for rapidly multiplying cells, such as blood cells. In addition, adequate intake of vitamin B-12, along with Folic Acid and Vitamin B-6, encourages healthy serum homocysteine levels, thereby supporting cardiovascular health. Vitamin B-12 is also formulated with the entire B-Complex family of vitamins, which work together to support cellular energy production. NOW® Vitamin B-12 is vegetarian/vegan (non-animal derived).

This product saved me.
Before I started taking this B12 I was taking a chewable version my husband got for me at the grocery store. It wasn't being absorbed enough into my body and I was having horrible panic attacks. The day the ultra B12 arrived they lessened and less than a month later my levels are good. I should mention I am a vegetarian. Also the taste is not unpleasant.

I use this daily!
For some odd reason I lost my B-12 and vitamin D in 2016. My PCP did this and that. I decided to take matters into my own hands. I found this product at GNC. Today I have more energy. At over sixty-five it feels real good to have the energy to get after my grandson and wear him down!

I love that this comes in a liquid form. I can take as much or as little as I like, and still get the B12 that I need daily.

Better than expected!!
I switched over to the NOW brand from another B12 supplement listed on here. Not knocking the other brand (by name) at all but the absorption response time of this B12 supplement is what sold me.

Great product!
I take Metformin for my diabetes and it can cause a b12 defeciency. I was told by a friend who also has diabetes to take b12 drops. I was blown away how great this product is. I'm NO longer tired in the afternoon and I have so much energy through out the day. I absolutely love it!. The only con I have with it, it says "Pleasant tasting".... it has a terrible taste to it but as great as it works I can tolerate the bad taste in my mouth for a few seconds. Try this product, you won't be dissappointed!

wonderful product
I can't believe the amount of energy that I seem to have now. The energy just seems to last and last. The cons about this item is that I no longer get a nap time.

I'm not sure what the reason for holding in mouth for 30 sec. Please forgive my ignorance. Thank you. Cathy Hickson.

BEST ANSWER: The reason you hold it in your mouth (should be under tongue) for 30 seconds is so that it can absorb better into your bloodstream.
