Anyone who has investigated the market for workout supplements for men knows that there is an incredible variety of supplements available for pre workout, between workouts, and post workout nutritional needs. Here, we’ll focus specifically on the main ingredients of pre workout supplements and examine how each of these ingredients works.

1: They Increase Blood Flow

Those in search of the best pre workout supplement for men will likely find that most of these workout supplements contain agents designed to stimulate the production of nitric oxide.

Nitric oxide is a molecule that works to dilate the blood vessels, which increases the flow of blood to muscles without increases blood pressure at the same time. While research on the efficacy of nitric oxide supplements has found inconsistent results, many athletes swear by them.

L-arginine and L-citrulline are two of the most popular nitric oxide supplements, but L-citrulline is generally more reliable, as it is a metabolic precursor to L-arginine and results in a longer-lasting effect. Many people report feeling an excellent muscle pump when taking L-arginine or L-citrulline, and this can provide a psychological benefit as well.

2: They Regenerate Cellular Energy

Most workout supplements for men contain creatine. Creatine is one of the best fitness supplements available, and it has been extensively researched. Much of the research on creatine has found that it improves performance.

Creatine works by assisting in the regeneration of adenosine triphosphate, or ATP. This is the main source of cellular energy in the body. When you exercise, ATP is used for energy. In this process, it loses a phosphate ion and becomes ADP (adenosine diphosphate).

Furthermore, creatine quickly supplies ADP with an additional phosphate ion, turning it back to ATP. In order to see a maximum benefit from creatine, it is necessary to take it regularly to ensure muscle tissue saturation.

3: They Improve Energy, Focus, and Drive

Many workout supplements for men will not only prepare the body for a good workout but will also help exercisers prepare mentally. Creatine, which we mentioned above, is probably best known for its ability to improve workout performance. However, one can also use it as a nootropic to improve focus and mental clarity.

Not all workout supplements for men contain creatine, but most contain caffeine. Most people know that caffeine can increase athletic performance while also slowing the onset of mental fatigue. Research has also found that caffeine increases pain tolerance. Therefore, you may find it easier to lift through minor muscle pain.

4: They Supply the Building Blocks of Protein Synthesis

Not all workout supplements for men include the building blocks of protein synthesis, but some do. Specifically, some higher-end or complete workout supplements contain branched-chain amino acids or BCAAs. These are free-form amino acids that may help guard against muscle catabolism.

You may already get enough BCAAs from dietary protein. Still, supplementing your diet with them may be a good idea if you are in a cutting cycle or otherwise eating less protein than you normally do.

Putting It All Together

It’s true that different workout supplements have different ingredient profiles. Still, the ingredients discussed above are some of the most popular workout supplement ingredients. First, you must understand how these supplements work. Then, you’ll be more likely to choose a workout supplement that supports your goals and makes each workout an effective one.
