What vitamins should I take for tiredness?

Fatigue is a common complaint with many potential causes. When poor sleep, stress, or low activity are not the primary drivers, nutrient shortfalls can contribute to persistent tiredness by impairing oxygen transport, cellular metabolism, or nervous system function. The most evidence-aligned approach is to consider targeted nutrients that support energy metabolism, confirm any deficiencies with testing, and combine supplementation with lifestyle measures.

Key nutrients linked to energy

Several vitamins and minerals are most consistently associated with reduced tiredness in clinical studies and regulatory statements. B vitamins (particularly B12 and folate) are central to red blood cell formation and metabolic pathways that convert food to usable energy. Iron is essential for hemoglobin and oxygen delivery; iron deficiency commonly causes weakness and reduced stamina. Magnesium is a cofactor in ATP production and influences muscle and nervous system function. Vitamin C supports iron absorption and acts as an antioxidant during recovery from physical stress. Vitamin D insufficiency has also been associated with low mood and lethargy in some contexts, though its links to energy are broader and often indirect.

Testing and safe use

Laboratory tests are the reliable way to identify deficiencies: a full blood count with ferritin and iron indices, serum B12 and folate, 25‑hydroxyvitamin D, and magnesium when clinically indicated. Avoid empiric high-dose supplementation without evidence — excessive iron, for example, can cause organ toxicity. When tests confirm deficiency, follow evidence-based repletion regimens and repeat testing to confirm recovery.

If you follow intermittent fasting or other eating patterns, consider interactions between timing and supplement absorption; guidance is available on taking supplements during intermittent fasting and in a practical article on intermittent fasting and supplements. These resources discuss when to take micronutrients for best absorption and tolerance.

Choosing supplements and routines

When deficiencies are absent but diet is limited, a balanced multivitamin or a B complex at recommended daily doses can fill gaps without creating imbalances. Stimulant-containing energy products (e.g., caffeine) can increase alertness short-term but should be used sparingly to avoid sleep disruption. Botanical adaptogens (such as rhodiola or ginseng) have variable evidence; if considered, select standardized extracts and review potential interactions with medications.

Practical lifestyle guidance

Dietary optimization — including lean proteins, legumes, whole grains, dark leafy greens, nuts and seeds — supplies many key cofactors for energy. Prioritize sleep, hydration, graded physical activity, and stress management to amplify the benefit of any nutritional strategy.

In summary: test if fatigue is persistent, correct confirmed deficiencies first, use balanced supplementation when needed, and combine nutrient strategies with foundational lifestyle measures. Seek clinical evaluation for severe, unexplained, or progressive fatigue.
