Whats the relationship between vitamin D and B12 levels and how they impact my energy levels, particularly during long rides or intense training sessions? Ive heard anecdotal evidence suggesting that deficiencies in these vitamins can lead to fatigue, but whats the scientific basis for this claim? Is it possible to over-supplement with these vitamins and experience negative effects, or is there a sweet spot that optimizes energy production?
Given that vitamin D is fat-soluble and can be stored in the body for extended periods, how does this affect its supplementation strategy for athletes? Should we prioritize sun exposure, dietary sources, or supplements to maintain optimal levels? And whats the ideal dosage for vitamin D in the context of athletic performance?
On the other hand, vitamin B12 is water-soluble and has a shorter half-life, but its still essential for energy metabolism. Whats the relationship between vitamin B12 levels and lactate threshold? Can supplementing with vitamin B12 improve my anaerobic capacity or reduce perceived exertion during high-intensity efforts?
Im also curious about the interactions between vitamins D and B12. Do they have synergistic effects on energy production, or can supplementing with one vitamin offset deficiencies in the other? Whats the current understanding of how these vitamins interact with other nutritional factors, such as iron, magnesium, and potassium, to influence athletic performance?
Lastly, whats the best way to assess vitamin D and B12 levels, and how often should athletes get tested? Can self-reported symptoms and performance metrics provide reliable indicators of deficiencies, or is laboratory testing the only way to determine optimal levels?
