Fatigue can be defined as a state of extreme tiredness. It can be mental or physical and is often caused by a lack of rest, working long hours, intense mental or physical activity and stress. Sleep disorders such as insomnia, sleep apnea and restless leg syndrome can all reduce sleep quality, which can also contribute to the development of fatigue. Vitamin deficiencies can also be a causal factor.
B Vitamins
B vitamin deficiencies are responsible for several fatigue conditions including beri-beri and pellagra. B-vitamin complexes come in standardized doses, over the counter, and one per day is generally sufficient to restore imbalances.
Vitamin A
When the immune system is functioning poorly, fatigue is much more common. Taking around 1000 mcg (microgram) of vitamin A in beta-carotene form can bolster the immune system.
Vitamin C
Like vitamin A, vitamin C also bolsters immune function, decreasing the likelihood of fatigue. A standard dose is 500 mg per day.
Magnesium
While not a vitamin, magnesium is widely used for both nerve and muscle function, both of which suffer with fatigue. A magnesium supplement of 300-400 mg per day can help to restore any deficiency.
Warning
Fatigue can be a symptom of other, extremely serious conditions. If your fatigue persists after rest and vitamin supplementation, seek the advice of a doctor.
