He fed Vegan B12 Liq 1000Mcg

Vitamin B12 is a water-soluble vitamin that, like the other B vitamins, contributes to red blood cell formation and helps maintain the proper functioning of the nervous system and a normal metabolism.

This micronutrient supports healthy skin, nails and hair. It also helps prevent megaloblastic anaemia, a condition that causes fatigue and muscle weakness. The main food sources are meat, fish, eggs and dairy products. Vegans or those following a vegetarian diet should consider taking a supplement for this vitamin to achieve optimal intake levels.
