Vitamins for Tiredness: A Comprehensive Review
Introduction to Fatigue and Nutrient Therapy
Fatigue, characterized by a lack of energy, mental exhaustion, and poor muscle endurance, is a common symptom in various conditions such as fibromyalgia, chronic fatigue syndrome, cancer, and multiple sclerosis. Vitamins and minerals play essential roles in metabolic pathways that support cellular functions, potentially mitigating physical and mental fatigue1.
Vitamin C and Fatigue Reduction
Vitamin C has shown promise in reducing fatigue, particularly in post-viral conditions like long COVID. High-dose intravenous (IV) vitamin C has been observed to significantly decrease fatigue scores in several clinical studies. Additionally, it alleviates attendant symptoms such as sleep disturbances, lack of concentration, depression, and pain. The antioxidant, anti-inflammatory, and immunomodulatory effects of vitamin C make it a suitable treatment option for fatigue2. Furthermore, vitamin C supplementation can reduce muscle soreness and oxidative stress following eccentric exercise, although it has limited impact on muscle function loss7.
B Vitamins and Energy Metabolism
B vitamins are crucial for energy metabolism, acting as cofactors in various metabolic processes. Supplementation with B vitamins, including B1, B2, B6, and B12, has been shown to enhance physical performance and reduce physical fatigue. A 28-day supplementation period significantly improved exercise endurance and reduced biochemical markers of exercise fatigue4. Additionally, professional athletes reported reduced fatigue symptoms, improved sleep quality, and decreased muscle damage after three months of daily B vitamin complex supplementation9.
Multivitamin/Mineral Supplementation
Multivitamin/mineral (MVM) supplementation has been associated with increased energy expenditure and reduced subjective tiredness. Studies have demonstrated that MVM can modulate energy metabolism and alleviate mental and physical fatigue, with differential effects observed between males and females. These findings suggest that MVM supplementation can provide acute and chronic benefits in reducing fatigue5.
Vitamin D and Fatigue in Chronic Conditions
Low vitamin D levels have been linked to increased fatigue, particularly in patients with advanced cancer and multiple sclerosis (MS). In men with cancer, higher vitamin D levels were associated with less fatigue, although this correlation was not observed in women6. A meta-analysis of randomized controlled trials indicated that vitamin D supplementation significantly reduces fatigue in individuals with MS, highlighting its potential therapeutic use10.
Conclusion
Vitamins and minerals play a vital role in mitigating fatigue across various populations. Vitamin C, B vitamins, and vitamin D have shown significant benefits in reducing fatigue and improving overall well-being. Multivitamin/mineral supplementation also offers promising results in enhancing energy metabolism and reducing tiredness. Further research is needed to explore these therapies as both adjunctive treatments and sole interventions for fatigue management.
