Athlete Talks About Using Performance-Enhancing Drugs

Performance-enhancing energy capsules -

These conditions are each characterized by weakness and fatigue. A review of seven clinical trials found that supplementing with high doses of B vitamins was associated with improvements in the following:.

Creatine is a popular supplement used by athletes to build muscle and enhance exercise performance. Creatine provides energy to cells in the muscles. It is made in the body, and levels can be boosted through the diet for instance, with red meat and fish or by taking supplements.

Most people need between 2 and 3 g of creatine a day. Creatine is likely beneficial for short bursts of high-intensity exercise. It can also improve symptoms of mental fatigue and enhance memory and cognition. Some research suggests it could benefit people with chronic fatigue syndrome or long COVID , but more research is needed.

Tyrosine is an amino acid that is made into chemical messengers called dopamine and norepinephrine in the body. These messengers may fight fatigue. Tyrosine is available as a dietary supplement. It's also found in lots of foods, including the following:. Tyrosine did not appear to improve physical performance, according to a review.

However, the authors suggested it may benefit mental performance during high-stress situations. In a human study, a single dose of tyrosine improved cognitive function in the short term. Selenium is a micronutrient found in foods like meats and fish. It's also available as a dietary supplement, though getting it from the diet is more effective in raising levels.

Adults typically need 55 micrograms mcg daily, and requirements increase during pregnancy and lactation. Selenium is highly concentrated in the thyroid gland.

It's involved in the production and breakdown of thyroid hormones. Adequate levels of selenium in the body are needed for healthy thyroid function and to prevent thyroid disorders. If your fatigue is associated with a thyroid condition, selenium could be a helpful add-on.

Remember that high amounts of selenium above mcg a day can cause toxicity. Some symptoms of toxicity include the following:. Ingredients commonly found in tea, like amino acid L-theanine and stimulant caffeine , may help combat fatigue.

A small study of 44 young adults showed that tea containing caffeine and L-theanine can improve symptoms associated with low energy levels, such as the following:. Caffeine's effects are increased by taking it in combination with L-theanine. Coenzyme Q10 CoQ10 is an antioxidant that protects the brain and reduces inflammation.

The jury is mixed on CoQ10's effects on energy levels, and benefits may vary. Trials show that taking at least mg daily may help people with fibromyalgia. It's also been studied for chronic fatigue syndrome, but with mixed results.

While one study reported improved energy levels for those who took CoQ10, another did not. For those without underlying conditions, CoQ10 may or may not increase energy.

More research is needed to know for sure. In the United States, the Food and Drug Administration FDA does not regulate supplements the way it regulates prescription drugs. That means some supplement products may not contain what the label says. When choosing a supplement , look for third-party tested products and consult a healthcare provider, registered dietitian nutritionist RD or RDN , or pharmacist.

Treatment for low energy will vary depending on the cause and may include wellness activities like the following:. Some supplements may help improve energy levels and combat fatigue. Before self-treating, though, it's important to consult with a healthcare provider to rule out any underlying issues that could be depleting your energy.

If a root cause of fatigue like apnea or a vitamin deficiency isn't corrected, supplements are unlikely to work. Many supplements are marketed for these indications, sometimes without much scientific evidence to support them.

Some supplements that have been studied include B vitamins, creatine, iron, selenium, tyrosine, and protein. Side effects of supplements that people use for energy vary.

Some, like creatine, are unlikely to cause serious side effects when used correctly. Others, like protein, may cause serious side effects, particularly when used at high doses. Because the FDA does not regulate supplements in the same way it does for drugs, supplements typically do not undergo rigorous testing like prescription medications do.

This means that often not much is know a lot about the possible side effects of supplements, especially when they are used long-term. Caffeine, for instance, is quick-acting. Maximum results are typically seen within 30 to 60 minutes.

CoQ10 does not act as quickly and may take eight weeks to see effects. O'Connor PJ, Kennedy DO, Stahl S. Mental energy: plausible neurological mechanisms and emerging research on the effects of natural dietary compounds.

Many other dietary supplements have been advertised for their purported ergogenic properties, and the list grows each year. Table 3 provides a brief summary of the most common agents that physicians may hear about from their patients who are athletes.

When counseling patients about ergogenic aids, it is important that the physician be knowledgeable about the topic. The intervention that carries the most impact is ensuring optimal dietary habits. Supplying adequate energy intake, carbohydrates and protein in the diet, and timing these to be efficiently used by the body, will provide the most effective and safe results.

If a patient asks about a specific ergogenic aid, he or she should be told what is known and unknown about the product based on current research, including the side effect profile.

The danger is that once athletes start using a commercial supplement, they will continue to use more, eventually trying something that may not be safe. Many athletes feel pressured to use supplements to maintain a competitive advantage over their supplement-using peers.

If physicians can guide athletes away from disproven and dangerous supplements, while maintaining open and honest lines of communication, then more serious health risks may be prevented.
