With a wide variety of products available, it’s essential to identify which ones are truly effective and in what contexts they are recommended. Below, we’ll analyze some of the most scientifically supported supplements and their applications for improving athletic performance and overall health.
Creatina monohidratada
Creatine monohydrate is one of the most studied and scientifically backed supplements. Naturally found in foods like meat and fish, its supplementation has proven particularly beneficial for those engaged in strength and high-intensity sports.

- Increased strength and power: Enhances performance in short-duration, high-intensity activities.
- Improved body composition: Promotes lean muscle mass gain.
- Delayed muscle fatigue: Enables longer and more efficient training sessions.
Usage Recommendations:
The typical dose is 3 to 5 grams daily, preferably after training, with plenty of water. It’s important to note that creatine monohydrate is safe for healthy individuals and does not require loading cycles.

Caffeine is a natural stimulant found in coffee, tea, and some sodas. Its effectiveness in improving athletic performance is well-documented.

- Reduced perceived exertion: Allows for maintaining exercise intensity for longer periods.
