what vitamins to take for tiredness
1. Vitamin B12. If you search for âhow to prevent fatigueâ 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.
Additionally, vitamin C is needed to help absorb iron properly and can help prevent anemia, another cause of fatigue.*. Vitamin C is water-soluble, so there is less danger of toxicity at high levels like there is with supplemental vitamin A. Too much vitamin C can potentially lead to some stomach upset.
