What is the healthiest thing to take for energy?
If you have low energy, certain vitamins and supplements may help improve your symptoms. Low levels of B vitamins, vitamin D, and iron can cause fatigue. But taking these vitamins is only likely to improve your energy if your levels are low. Ginseng, coenzyme Q10 (CoQ10), and ashwagandha may all help increase energy. Vitamin B12 and folate perform several important functions in the body, including keeping the nervous system healthy. A deficiency in either of these vitamins can cause a wide range of problems, including: extreme tiredness.Vitamin B12 is an essential nutrient needed for the proper functioning of our brain and central nervous system. While it can prevent tiredness and fatigue in those who are deficient in B12, it does not directly affect our energy levels like caffeine does.
