While most individuals take note of their macronutrients (protein, carbohydrates, and fats), they typically overlook about watching their micronutrients—the nutritional vitamins and minerals in meals. “Micronutrients are key to supporting energy metabolism, oxygen transfer and delivery, and tissue repair,” says Marni Sumbal, nutritionist and proprietor of Trimarni Coaching and Nutrition in Greenville, South Carolina.
If your physique is a machine, consider micronutrients because the gears—they facilitate the metabolic reactions that assist flip meals into gas, says Ingrid Skoog, nutritionist and teacher at Oregon State University’s College of Public Health and Human Sciences. And though all nutritional vitamins and minerals are important to your general well being, a couple of are particularly essential for athletes. To optimize your efficiency, give attention to these eight, and intention to get them (ideally) by real-food sources slightly than dietary supplements.
What It Does: Iron helps purple blood cells carry oxygen to muscular tissues, says Sumbal, which is important for improved endurance. Research exhibits that common endurance coaching results in a larger every day lack of iron, making deficiencies frequent among the many extremely energetic. To fight this expedited fast loss, the Food and Nutrition Board suggests a 30 p.c improve in iron consumption for individuals who train intensely frequently.
Where to Find It: Oysters, clams, purple meat, fish, raisins, tofu, lentils, and white beans are all nice sources of iron. Another stable (and low-cost) choice: A cup of cooked spinach incorporates about 80 p.c of the every day beneficial allowance for males and 35 p.c for girls.
What They Do: Each B vitamin—together with folate, thiamin, riboflavin, niacin, B6, B12, pantothenic acid, and biotin—has a task in vitality manufacturing, however a lot of them work collectively for larger influence, says Sumbal. Specifically, they break down carbohydrates into glucose for vitality and assist course of fats and protein. “They’re like a flame to the fire,” she says. Among the B nutritional vitamins, B12 stands out for its operate in purple blood cell manufacturing and the synthesis of DNA. Since purple blood cells are chargeable for eradicating carbon dioxide out of your physique and carrying oxygen, it’s particularly necessary that endurance athletes hold their B12 ranges excessive.
Where to Find Them: Chicken, beef, leafy greens, eggs, milk, beans, and entire grains all comprise most B nutritional vitamins. Animal sources are the very best B12 sources, however vegans or vegetarians may discover it in fortified cereals and dietary yeast.
Vitamin D + Calcium
What They Do: Vitamin D and calcium work hand in hand for bone well being. Although calcium by itself will make your bones stronger and work as an anti-inflammatory, it gained’t be totally absorbed with out the assistance of vitamin D. Shortage of this vitamin is shockingly frequent in outside athletes, most of whom assume they’re getting sufficient from daylight alone. “Especially if you’re a winter sports athlete, you may not be getting the exposure you think you are,” says Skoog.
Where to Find Them: Most dairy merchandise—like cheese, milk, and yogurt—present an excellent dose of each calcium and vitamin D. Since vitamin D is greatest absorbed when paired with fats, go for a full-fat choice slightly than a fat-free different, says Sumbal. Salmon is one other nice supply of each.
What It Does: It’s recognized for combating off illness, and for good motive. Vitamin C is a serious immunity booster, and analysis revealed in Medicine and Science in Sports and Exercise has proven that long-lasting train at a reasonable depth decreases immunity.

What It Does: Magnesium performs a task in nerve and muscle operate, together with how the guts contracts, says Sumbal. It additionally assists in protein, fats, and carbohydrate synthesis and electrolyte stability. When there’s not sufficient magnesium within the cells, the muscular tissues and nerves can turn out to be burdened, inflicting cramping or stressed legs and involuntary spasms, she says.
Where to Find It: To hit the beneficial every day allowance of 420 milligrams for males and 320 milligrams for girls, intention for a every day mixture of deep-green leafy greens, nuts, seeds, and entire grains.
Potassium + Sodium
What They Do: Potassium is likely one of the 3 main electrolytes and works together with sodium to keep up cells’ membrane potential. That’s a flowery means of claiming it’s largely chargeable for correct muscle contraction, coronary heart operate, and communication between nerves. The 2 micronutrients additionally work collectively to keep up fluid stability within the physique. During train, you lose electrolytes by sweat, which might result in fatigue and muscle cramping, however potassium and sodium assist restore correct hydration and hold these unwanted side effects at bay.
Where to Find Them: Bananas are the standard go-to for a dose of potassium, however a small white potato with the pores and skin on incorporates virtually double the banana’s potassium depend. Other good potassium sources embody oranges, beans, salmon, and milk. For a fast sodium repair, merely add a touch of desk salt your meals. Sprinkle a potato with salt for a fast one-two punch after an intense endurance session to rebalance electrolytes.
