Factors for Support of B-12 Bioavailability
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).
Supplementation with B-12 Intrinsic Factor:
• Supports nervous system health
• Supports red blood cell production
• Supports energy
• Supports metabolism of fats and carbohydrates

Optimal Quality
Format: Board book
This book is sturdy, colorful and cute. The baby likes it, so we are happy we got it. The whole collection is worthwhile, and is very well designed for little hands. The baby is now 18 mo old.

Lazy quality
Format: Board book
My book came with a big, ugly, torn off sticker across the front. We collect the Babies Love books for our baby and I just really did not appreciate the ugliness of the outer cover. Seems like laziness to not remove that before sending it to a paying customer.

Just ok
Format: Board book
Love the concept of teaching baby kindness. The words in this one miss the mark unfortunately. This is not one of our favorites.
