If you’re chasing athletic goals and milestones, you might be focused on training hard. Recovery is just as important as training for athletes – and you may not have considered the best vitamins for athletes.
But what if the key to improving your stamina, recovery, and endurance was hiding in your daily diet? Vitamins and minerals—often overshadowed by protein powders and carb-loading strategies—are the secret weapons your body needs to perform at its best.
Micronutrients play a role in processes like energy production, muscle contraction, and immune function (1). Yet, they are frequently overlooked, and many athletes don’t realize how even minor deficiencies can compromise performance (2).
We’ll break down the vitamins and minerals that matter most for athletes, highlight common deficiencies, and guide you on how to track and optimize your intake with MyFitnessPal.

Vitamins and minerals are necessary for countless bodily processes that support athletic performance (2).
Understanding their roles can help you prioritize these micronutrients in your diet and enhance your stamina, recovery, and overall fitness.
Vitamin A helps maintain healthy vision, which can be important for athletes playing in dimly lit environments or during night games. Beyond vision, Vitamin A supports your immune system, helping you stay healthy and fend off germs during rigorous training periods (2).
Incorporate foods like sweet potatoes, carrots, spinach, and cantaloupe into your diet to support healthy Vitamin A levels.
Vitamin C is a potent antioxidant that protects your muscles from oxidative stress caused by intense exercise (3).
Additionally, Vitamin C allows for optimal iron absorption, reducing the risk of fatigue caused by low iron levels. (15)
Common sources of Vitamin C include citrus fruits, bell peppers, broccoli, and strawberries.
Known as the “sunshine vitamin,” Vitamin D plays a role in calcium absorption, bone strength, and muscle function (4).
For athletes, Vitamin D contributes to improved muscle performance, coordination, and recovery after intense training. It supports optimal bone density, allowing athletes to handle the physical demands of high-impact sports. (16)
While sunlight is the best source of Vitamin D, foods like salmon, fortified dairy products, and egg yolks can help meet your needs, particularly during winter months.

Calcium is essential for maintaining bone strength and also plays a role in muscle contraction, nervous system function, energy production, hormone function, and more (5).
For athletes, adequate calcium intake helps prevent stress fractures and supports muscle recovery after strenuous activity. (5)
Dairy products like milk, yogurt, and cheese are excellent sources, as are non-dairy options like tofu, kale, and broccoli.
Iron is an indispensable mineral for athletes because it aids in oxygen transportation (6). This process ensures your muscles receive the oxygen they need during exercise, supporting endurance and energy levels.
To meet your iron needs, include foods like lean red meats, spinach, lentils, and fortified cereals in your diet.
Potassium is an electrolyte that helps regulate fluid balance, prevent dehydration, maintain healthy blood pressure, and support muscle contractions (7).
It also helps reduce lactic acid and is involved in the breakdown of carbohydrates (2).
Athletes can lose potassium through sweat and urine, so it’s important to eat potassium-rich foods like bananas, potatoes, avocados, dried fruits, and beans on a regular basis.
Athletes are often at a higher risk of nutrient deficiencies due to their rigorous training regimens, increased energy demands, and nutrient loss through sweating. (17)
Busy schedules and time constraints can also make it challenging to prepare balanced meals, plus, intense exercise may suppress appetite, leading to insufficient nutrient intake.
These factors may all increase the likelihood of deficiencies, which could in turn hinder performance and recovery if left unaddressed.
Iron deficiency is one of the most common issues among athletes, particularly female athletes and those in endurance sports like running or cycling. (8)
Strenuous exercise can increase iron loss through sweat, urine, repeated impact of feet on the ground (foot-strike hemolysis) and even gastrointestinal bleeding.
Studies have shown that up to 52% of female adolescent athletes and 30-50% of endurance athletes are iron deficient. (8)
Low-iron can lead to fatigue, weakened endurance, and a higher risk of overtraining syndrome.
Despite its importance for bone health and muscle function, Vitamin D deficiency is prevalent among athletes, especially those who train indoors or live in areas with limited sunlight. Plus, perhaps due to their increased nutrient demands, 56 percent of athletes have vitamin D deficiency compared to their general population counterparts (24-40%) (9).
Deficiency can lead to weaker bones, a higher risk of stress fractures, and slower recovery times.
Calcium deficiency is often seen in athletes with restricted diets, such as those avoiding dairy or following plant-based diets. This deficiency is particularly concerning for female athletes, who may also experience relative energy deficiency in sport (REDs), a condition involving low energy availability, menstrual dysfunction, and weakened bone density. (18)
In a 2023 study of 95 endurance athletes, 42% of the participants had insufficient calcium intakes (10).
Without sufficient calcium, athletes face an increased risk of fractures and impaired muscle function.
Potassium is a key electrolyte lost through sweat, which is why athletes who exercise in the heat or participate in high-impact or endurance sports tend to be more prone to deficiency. In a small study of 95 endurance athletes, nearly 57% did not consume the recommended amount of potassium (10).
Insufficient potassium can lead to muscle cramps, dehydration, and even arrhythmias in severe cases.
Magnesium plays a role in over 300 biomechanical reactions in the body, and helps with muscle relaxation and energy production. (19)
But many athletes fall short due to increased losses through sweat and urine. An 8-year analysis of 192 British Olympic and Paralympic track and field athletes concluded that 22% of the participants were clinically deficient in magnesium (11).
Deficiency can lead to muscle cramps, fatigue, and poor sleep, all of which impair recovery and performance.
Athletes may also experience zinc deficiency due to increased requirements and losses during prolonged physical activity.
A 2018 review of twelve studies found that athletes have lower serum zinc levels than control populations, despite higher zinc intakes (12). This suggests athletes may have higher zinc requirements than the general population.
Zinc is essential for immune function, wound healing, and muscle repair, but low levels can weaken immunity and prolong recovery.
