Zinc is a trace element that is essential for the proper functioning of the body and plays an important role in various biological processes. For athletes, especially those who practice bodybuilding, zinc has many benefits.
Here, we'll look at the benefits of zinc , its actions in the body, food sources rich in zinc , as well as dosage recommendations and precautions to take when taking it.
The benefits of zinc
Testosterone production
Zinc is essential for the production of testosterone, the key hormone for muscle building. Adequate zinc therefore stimulates muscle protein synthesis, promotes recovery after training and contributes to your overall muscle growth.
Testosterone is fundamental for athletes, helping them build muscle mass, reduce fat mass and improve physical performance.
Essential metabolic functions
Zinc is involved in over 70 essential metabolic actions, including DNA and RNA synthesis and repair, sexual maturation, wound healing, and the health of skin, hair, and nails. It also greatly influences bone health and immune function.
Zinc is essential for the metabolism of proteins, carbohydrates and lipids, making it an important element for athletes looking to optimize their performance and recovery.
Improving sports performance
Studies have shown that adequate zinc levels improve athletic performance by increasing muscle strength and endurance. Zinc deficiency can slow recovery after training and affect strength training progress.
A study published in the Journal of Exercise Nutrition and Biochemistry found that low zinc levels could lead to decreased muscle strength and endurance in athletes.
Immune support
Zinc is essential for maintaining a strong immune system, which is especially important for athletes undergoing intensive training regimens that can weaken their immunity.
Good immunity allows athletes to stay healthy and maintain a regular training schedule without interruption.
Skin, Hair and Nail Health
For athletes, maintaining an optimal physical appearance is often important. Zinc contributes to healthy skin, strong hair and strong nails.
It also helps heal minor cuts and scrapes, common among athletes, faster.
Reduction of inflammation
Zinc has anti-inflammatory properties, which can help reduce inflammation after intense workouts.
Reducing inflammation allows for faster recovery and helps reduce the risk of long-term injury.
Food sources of zinc
It is essential to consume foods rich in zinc to maintain adequate levels in the body. Here is a list of food sources rich in zinc :
- Oysters: 78.6 mg per 100 g
- Wheat germ: 16.7 mg per 100 g
- Beef: 7.2 mg per 100 g
- Pork meat: 2.9 mg per 100 g
- White beans: 2.4 mg per 100 g
- Chicken meat: 2.3 mg per 100 g
Including these foods in your diet can help maintain adequate zinc levels. However, for athletes who have increased needs, it may be necessary to take zinc supplements.
Recommended Zinc Supplements
For athletes with increased zinc needs, taking a health supplement may be necessary. Here are some common options:
- Zinc tablets: Zinc tablets are popular for their ease of use and dosage accuracy, thanks to their different concentrations. Easy to carry, they can be taken at any time with water. They are generally well tolerated.
- Zinc Powder: Zinc powder is valued for its flexibility, being able to be mixed into water, protein shakes or other beverages.

It is crucial to mix the powder well for even absorption of zinc.
- Zinc Gummies: Zinc gummies are convenient and enjoyable for those who prefer to avoid tablets. Flavored for a smoother consumption, they are popular among young adults and active people. They make it easy to incorporate zinc into your daily routine.
Keep in mind that it is important to choose high quality supplements from reputable brands.
Proper dosage
Zinc requirements vary depending on age, gender, and physical activity level. Recommended dosages are:
- Adult men: 11 mg per day
- Adult women: 8 mg per day
- Adolescents: 34 mg per day
- Adults: 40 mg per day
Respecting these dosages allows you to benefit from the benefits of zinc without risking the side effects linked to overconsumption.
H2 Everything you need to know before taking zinc
Before starting zinc supplements, it is important to consult a healthcare professional to check for zinc deficiency and determine the doses that will benefit you.
An overdose of zinc can lead to side effects such as digestive upset, copper deficiency and decreased immunity.
Possible side effects
Excessive use of zinc supplements can cause adverse effects. Here are some possible side effects of taking too much zinc:
- Increased cholesterol levels: High doses of zinc may cause increased cholesterol levels.
- Stomach pain: Taking too much zinc can cause stomach pain, nausea, and vomiting.
- Diarrhea: Some individuals may develop digestive upsets such as diarrhea when taking excessive doses of zinc.
It is important to note that these side effects usually only occur in cases of significant overdose. Respect the recommended dosages and consult a professional immediately as soon as a symptom appears in order to avoid any complications.
Zinc absorption in bodybuilding
Zinc absorption in the body can vary depending on several factors. Some foods containing phytic acid, iron or calcium can hinder the absorption of zinc . Therefore, it is recommended to take zinc supplements between meals to optimize its absorption. Additionally, the amount of zinc you need depends on your age, gender and lifestyle. It is important not to exceed the recommended doses to avoid adverse effects.
To facilitate the absorption and effective use of zinc, it is recommended to take it with a meal containing protein, as this promotes the absorption of zinc by the intestine. Avoid taking it at the same time as foods rich in phytic acid, such as whole grains and legumes, as this can reduce the absorption of zinc . By taking zinc supplements between meals, you also avoid any interactions with other minerals , such as iron and calcium, which can also affect its absorption.
Zinc Rich Foods for Bodybuilding
When it comes to optimizing your bodybuilding results, it is important to maintain adequate levels of zinc in the body. In addition to zinc supplements, you can also get this essential mineral from zinc-rich foods.
Here is a list of foods that can help you boost your zinc intake quickly:
- Oysters: Oysters are one of the richest sources of zinc . A serving of six oysters can provide up to 32 mg of zinc.
- Wheat Germ: Wheat germ is another great source of zinc. It can be added to your smoothies, cereals, or yogurts to increase your zinc intake .
- Beef and Pork: Red meat is a source of zinc that is easily absorbed by the body. Beef and pork also contain other important nutrients for bodybuilding, such as iron and protein.
- White Beans: White beans are not only rich in zinc , but they are also an excellent source of fiber and plant-based protein.
- Chicken Meat: Chicken meat is another lean source of zinc that can be incorporated into your diet to increase your zinc intake .
