How much vitamin B12 do I need?
The recommended daily dosage for vitamin B12 is 2.4 mcg.
But, vitamin B12 deficiency is pretty common among older or overweight people, and people who follow plant-based diets. Plants don’t contain vitamin B12. Only fortified foods and foods from animal sources are rich in vitamin B12.
Therefore, many people would benefit from taking vitamin B12 supplements. A weekly vitamin B12 dosage of 1,000 mcg is enough in most cases. Take vitamin B12 supplements at breakfast or first thing in the morning.
Vitamin B12 protects hair follicles
Hair is made of keratin. But, hair starts growing at hair follicles. Hair follicles need lots of nutrients to function properly. Blood vessels supply nutrients and oxygen to hair follicles.
Specifically, red blood cells transfer oxygen to hair follicles, keeping them healthy. Vitamin B12 is necessary for the synthesis of red blood cells and healthy blood cells.
But, low levels of vitamin B12 may cause fragile hair or even hair loss, as blood cells can’t supply enough nutrients to hair follicles. So, they can’t grow hair effectively, or they grow fragile and weak hair, leading eventually to hair loss.
Besides, poor blood circulation, hair follicles can’t function properly when we fail to consume enough vitamins, minerals, and other necessary compounds. Severe lack of nutrients may cause hair follicles to die!
We need many nutrients for strong and thick hair. For instance, we need to take adequate amounts of vitamins A, C, D & E! You can see the whole list of necessary nutrients for healthy hair here.
