Suplementos antes del ejercicio

Pre-workout supplements are designed to help you train, to give you the strength to push your limits from workout to workout. These supplements combine the power of different active ingredients, so they work in more ways than one.

Added creatine is most likely to increase strength and power in the 1-8 repetition range or sprints (for loads up to 30 seconds).

The blood flow enhancers (l-arginine, citrulline and ornithine) dilate blood vessels, allowing more nutrients to reach the muscles, which can also benefit endurance athletes (runners, swimmers, cyclists, etc.). Don't worry if you have high blood pressure or are sensitive to caffeine, supplements containing only blood-levelling agents have a blood pressure lowering effect. However if you have a medical condition, consult a doctor before taking them.

• L-taurine boosts brain function and concentration.
• L-tyrosine increases concentration in stressful situations such as training or competition.

Added caffeine increases alertness, blood pressure and concentration. However, there are also specifically non-stimulant energy boosters that do not raise blood pressure to any great extent.

A really good energy booster has a slow onset of action, it doesn't hit as hard, but even after the 1.5 to 2 hour workout, you won't feel lethargic.

Keep trying and after a while you will find the one that suits you best. We have a wide range of energy boosters to choose from.
