Why are vitamins crucial?

An athlete’s body demands more energy and nutrients.
Vitamins help with muscle recovery, strengthen the immune system, and optimize endurance.
Luis Isaias points out that while a balanced diet provides most of the necessary vitamins, in some cases, supplementation can be helpful.
Essential vitamins for athletes
Vitamin C
This vitamin is crucial for muscle recovery.
It helps reduce inflammation, improves iron absorption, and strengthens the immune system.
Luis Isaias suggests increasing vitamin C intake after intense training.
Vitamin D
Vitamin D not only strengthens bones but also improves muscle function.
Athletes who train outdoors usually get enough of this vitamin, but Luis Isaias mentions that it’s advisable to monitor levels, especially during periods of less sun exposure.
B Complex
B vitamins are essential for energy production.
They include B1, B2, B6, and B12, which support the metabolism of fats and carbohydrates for athletes.
Luis Isaias emphasizes that athletes should pay attention to their daily intake of these vitamins to maximize performance.
Vitamin E
Vitamin E is a powerful antioxidant.
It protects cells from damage caused by oxidative stress, which is common in athletes due to constant physical exertion.
Luis Isaias recommends including sources of vitamin E such as nuts and vegetable oils.
The role of antioxidants in sports nutrition
Antioxidants, such as vitamin E, help reduce oxidative stress, which is common during intense physical activity.
Athletes are often exposed to higher levels of free radicals due to exercise.
Natural sources of vitamins for athletes

Vitamins for athletes should not come solely from supplements.
Luis Isaias always advises getting vitamins primarily from natural foods. Some recommended sources are:
- Vitamin C: citrus fruits, strawberries, broccoli.
- Vitamin D: fatty fish, egg yolks.
- B Complex: whole grains, legumes.
- Vitamin E: almonds, avocado.
When do athletes need supplements?
Although it’s ideal to get nutrients from food, Luis Isaias admits that sometimes supplements of vitamins for athletes are necessary.
Factors such as the type of training, intensity, and personal needs can mean some athletes require extra help.
However, he stresses that this should be assessed by a nutritionist.
Myths about vitamin use
There are many myths surrounding vitamins.
One of the most common is that “more is always better.”
Luis Isaias debunks this myth, explaining that excess intake of certain vitamins can be counterproductive.
Consuming high doses of fat-soluble vitamins like D and E can lead to toxicity.
How many vitamins are enough according to Luis Isaias?
