Performance-enhancing supplements -

BCAAs can provide energy during exercise when metabolized, possibly providing greater strength and muscle mass gains from training. With no reported adverse effects for doses of up to 20 grams per day for up to six weeks, BCAAs fall under the category of safe and legal performance-enhancing supplements.

In addition, Ingredient Optimized options such as ioBCAA offer increased bioavailability of each of the three essential amino acids to ensure you receive the best possible benefits.

Protein is one of the most common performance-enhancing supplements among athletes and non-athletes alike. Protein assists with building, maintaining, and repairing muscle tissue, and it has been proven effective in numerous clinical trials. A quality protein supplement can optimize muscle training response during and after exercise.

There are no adverse effects or safety concerns reported at daily recommended intakes for athletes of up to 2 grams of protein per kilogram of body weight one kilogram equals 2. These products have been scientifically proven to offer better bioavailability than non-optimized protein supplements, ensuring you see results and are not wasting your money.

Creatine is a widely-used, thoroughly studied dietary supplement for sports performance. It can help supply energy to your muscles for short-term, anaerobic activities, such as HIIT, weight training, and circuit training. Aside from supplementation, creatine is obtained in small amounts from food and produced by your body.

Creatine supplementation may help you increase power and strength from full effort muscle contractions. It can also help your body adapt to athlete training regimens over time. It should be noted, however, that creatine does significantly enhance performance in endurance activities. Typical doses of up to 20 grams per day for up to seven days or grams for up to 12 weeks show minimal safety concerns.

Adverse effects are most likely to include weight gain caused by water retention, not fat accumulation , muscle cramps, muscle stiffness, and nausea. Creatine monohydrate is the most widely used and well-researched form of creatine, but it also comes in creatine anhydrous, which contains more creatine by weight.

Both options offer the benefits of creatine supplementation. Caffeine is one of the most widely used substances in the world.

Caffeine works by blocking the activity of adenosine, a neuromodulator that can make you feel sleepy or tired. In doing so, it reduces perceived exertion and even pain. Caffeine may enhance athletic performance for endurance activities and long-duration activities like playing sports.

Adverse effects may include irritability, blood pressure spikes , increased heart rate, restlessness, insomnia, arrhythmia, nausea, and vomiting. When taken in very high doses of grams 10,, mg , caffeine is also associated with a risk of death. Caffeine from pre-workout supplements, energy drinks, and coffee can add up fast.

Beetroot and beet juice is a safe and potentially effective performance-enhancing supplement. Beetroot and beet juice may improve energy production , reduce muscle oxygen use, and dilate blood vessels in the muscles you are exercising.

This veggie might also improve endurance and time-to-exhaustion among endurance athletes such as cyclists, runners, and swimmers. Beets also contain betaine trimethylglycine , which may help enhance athletic performance, although the exact mechanisms that allow it to do so are not fully understood.

Common hypotheses speculate that betaine may increase the biosynthesis or creation of creatine. It might also assist with water retention in cells and blood nitric acid levels. Beetroot, beet juice, and betaine have no associated safety concerns for short-term use. Bodybuilding - Randomized Controlled Trials PubMed®.
