Energy balance
Marginal deficiencies in B vitamins, magnesium, and zinc impair cellular energy production, leading to fatigue, tiredness, and reduced physical performance in active individuals.
Chronic fatigue in active people is often linked to low intake of B vitamins, magnesium, or zinc. Focus on improving your diet to include these nutrients rather than just pushing through the tiredness. If you diet or exercise heavily, your needs for these nutrients are higher.
GoodSupportsHIGH confidence
This paper is based on the recognition that a lack of micronutrients may impair cellular energy production, resulting in symptoms of tiredness and lack of energy.
Why this rating
Supported by extensive biochemical literature and multiple cited studies on specific nutrients.
