## Description

Vitamin B12 is a water-soluble vitamin needed for normal nerve cell activity, DNA replication, and production of the mood-affecting substance SAMe (S-adenosyl-Lmethionine). Vitamin B12 acts with folic acid and vitamin B6 to control homocysteine levels. Absorption of vitamin B12 is reduced with increasing age. Some research suggests that elderly people may benefit from 10 to 25 mcg per day of vitamin B12. One study of elderly people with vitamin B12 deficiency suggested that as much as 500 to 1,000 mcg of vitamin B12 per day might be necessary to achieve optimal vitamin B12 status. Vitamin B12 status was measured in this study using a sensitive laboratory test (the plasma methylmalonic acid concentration).

## Customer Reviews

### ⭐⭐⭐⭐⭐ Excellent product
*by C***E on May 25, 2022*

This product is a good product for anyone but it has just the right kind of B vitamin for the MTHFR.. I'm so glad this product also has Intrinsic Factor because that is very hard to find and is often the key to dealing with some variations of the MTHFR. Progressive Labs is known for the purity and integrity of their products.

### ⭐⭐⭐⭐⭐ If you have intrinsic factor issues this is good for that to absorb B vitamins...folate and B12
*by D***E on January 3, 2021*

Good stuff...

### ⭐⭐⭐⭐⭐ Helps Body Absorb B-12 After Gastric Surgery. I don't secrete intrinsic factor after Gastric Bypass.
*by C***S on January 28, 2020*

Great Product; wish it came in liquid form because I don't like swallowing pillls.
