Vitamins for Athletes: How Much is Enough?
Diet and exercise go hand in hand these days. Most people change their diets when they begin an exercise program, or at the least, they become more mindful of what they eat and drink. Whether you are exercising to lose weight, gain muscle, train for a marathon, or to maintain a healthy heart, a diet will play a significant role in the outcomes. Many active people include supplements and various vitamins for athletes in their diet to get more nutrients that may be missing in their regular diets or for the sake of enhancing their performance or recovery. The best approach to nutrition is to eat a well-balanced diet from every food group, making sure to include all vitamins and minerals your body needs. For the majority of people who live a busy lifestyle, this may not always be possible.
There has been a large amount of research done on supplementation in the general population as well as needed vitamins for athletes. In any community, many factors can affect what the body needs, such as illness and disease, regular diet, activity level, genetics, and even the amount of time we spend indoors versus outdoors! People who lower their food intake to lose weight end up lacking the necessary nutrients the body needs. On the other spectrum, high-intensity athletes, especially marathoners, tend to lose nutrients and not replace them sufficiently due to higher metabolic rates. Both of these categories require a certain amount of nutrients, including vitamins and minerals for the body to perform at any state and maintain proper organ function.
Since many vitamin and mineral supplement bottles are labeled with a notice that states they are not FDA approved, many people are opposed to taking them. It isn’t until they develop a symptom or specific results from routine bloodwork that they pay more attention to making the essential missing nutrients. It would be helpful to get evaluated by your doctor and get routine bloodwork done before any negative symptoms or illness develop since it is possible that a body can naturally not produce or absorb certain nutrients even when given a wholesome diet. If you are trying to lose weight and know that you are cutting out certain food groups, or are an athlete performing at higher intensity levels or for long durations, you may want to consider including proper supplementation including vitamins for athletes to keep your body going.
Calcium and Vitamin D
Bone health is a popular topic throughout life. Most children are brought up learning to drink calcium-rich milk every day to make and keep bones strong. Besides being a bone-strengthener, calcium is also in charge of other vital roles in our bodies such as nerve conduction, muscle contraction, and aiding in blood clotting. Many food sources are rich in calcium besides milk, including almonds, kale, broccoli, yogurt, and most other dairy products. Adequate amounts of Vitamin D should also be included as it is responsible for the calcium absorption, as well as other functions such as helping reduce inflammation in the body and for immune health. More recent studies have shown that insufficient Vitamin D intake may lead to more incidences of stress fractures and decreased performance levels. Foods high in Vitamin D include milk, mushrooms, eggs, and most seafood. The easiest way to increase vitamin D intake is to spend an extra ten minutes in the sunlight!
Iron and Vitamin C
The most crucial role iron plays in the body is to transport oxygen in the blood to the tissues, basically ensuring proper muscle function. It is a significant factor for athletes who want to perform at their best. During recovery from strenuous exercises, such as long distance running, iron helps to produce new cells and repair our damaged muscles. It is crucial for high intensity and endurance athletes to include the recommended amount of iron in their diets. Women, in particular, should be aware that their requirements are higher than for men. Iron deficiency can be caused by blood loss, poor absorption, or inadequate intake through diet. The antioxidant Vitamin C plays a role in the proper absorption of iron, as long as it is ingested at the same time. Vitamin C is also vital for the repair of damaged tissue and immune health.
For active individuals who train at high intensities or for prolonged periods, it is essential to include the recommended amount of vitamins for athletes, especially B-vitamins, to be able to perform at their best. These critical group of substances is in charge of the proper metabolism of macronutrients, carbohydrates, proteins, and fats. Some B-vitamins help our bodies rely on carbohydrates for energy, which may assist in delaying the glycogen depletion process. It is desirable for a marathon runner who wants sustained energy for as long as possible. These vitamins are abundant in many food sources, so it is not difficult to ensure adequate intake. Fortified cereals, vegetables, lentils, animal products, and nuts are all rich in most B-vitamins.
Many vitamins, minerals, and antioxidants aid in the metabolism of macronutrients, including magnesium, which is essential for muscle health. Its role in protein synthesis is especially critical to the recovery process when muscle tissue is broken down during exercise. Magnesium also plays a role in oxygen uptake, therefore making it beneficial for high intensity and prolonged exercise, since there is a need for higher oxygen requirements. During activities that result in increased sweat loss, magnesium is known to be one of the electrolytes lost during the process, which will decline exercise performance if not replaced. Good high-magnesium food sources include seeds, legumes, bananas, avocados, and dark chocolate.
Upper Intake Level
Although the dietary requirements of vitamins and minerals vary from one individual to another, it is essential to note that there is a maximum. Many studies have shown there are benefits to including the proper amount of vitamins for athletes in an athlete’s diet, but going beyond the maximum level will not enhance performance further. There are harmful effects of ingesting too much of any nutrient, such as the increased risk of toxicity, interference in the absorption of other medications and nutrients, immunosuppression, and oxidative damage. As mentioned earlier, it is best to include a balanced variety of food groups in your daily diet with plenty of fruits, vegetables, and other fortified sources before opting for supplementation. If your diet is lacking in a particular food group, such as in a vegan or vegetarian diet, or a low-calorie diet used for weight loss, and it is challenging to include a variety of vitamin-rich food sources, supplementation, and vitamins for athletes may be necessary. Many health conditions and disease can alter the number of nutrients and vitamins our bodies require, which is why it is always best to consult a medical professional before modifying your diet.
