what vitamins to take for tiredness
1. Vitamin B12. If you search for “how to prevent fatigue” in a text book or on the internet, Vitamin B12 will always come up! Vitamin B12 is a water soluble vitamin which has its effects predominantly on the actions and functions of the brain and nervous system. One study examined the benefit of vitamin B12 injections over 2,000 people. They did not find any positive effect until they increased the dosage to 2,500-5,000mg every 2-3 days.
Vitamin B12 is important for the way the body works, and people who don't have enough of it may feel tired or have a lack of energy. Vitamin B12 helps in the production of healthy red blood cells that carry oxygen around the body. Not having enough vitamin B12 is called vitamin B12 deficiency anaemia.
