In pre-exercise, arginine causes increased blood vessels and increased blood flow. Studies show that the half-life of arginine can range from 30 to 120 minutes, based on dosage and specificity.

The longer half-life of caffeine is around 5 hours. Research suggests that the acute effects of caffeine begin to appear at the end of one hour and may last between 1.5-9.5 hours, depending on the person.

When you’re using a caffeinated pre-workout supplement, the timing of your intake is crucial.

If you take it too early or you will suffer from a coffee crash. If you are too late, you will notice their effects until later during the exercise.

The majority of people experience its effects immediately after taking it. After consumption, the majority of caffeine is absorbed within 45 minutes. But it will reach the peak of its efficiency, on average, in about 30-60 minutes.

With this knowledge in mind, you will notice why experts advise performing a pre-workout 15-30 minutes before the start of the workout.

If you know how long the pre-workout period lasts, now you should decide to use a pre-workout supplement; there are several ways to make sure it is safe:

– Limit your intake to one serving each day.

Beware of other caffeinated or niacin supplements when you plan to use them as a workout before your workout the next day.

  • Look for products that have been evaluated by an external organization, for example, Labdoor and Eurofins Scientific.
  • Make sure each ingredient is listed and the exact amount per serving.
  • Study each ingredient thoroughly to determine what it is and detect any adverse reactions or potential risks.
  • Beware of previous workouts with so-called proprietary mixtures that do not mention the number of grams per ingredient in one serving.
  • Be sure to stick to a single dose of any pre-workout regimen you take – only half a dose for those in the middle. This is crucial when trying a new workout routine for the first time.

If you are taking medication or have medical problems, consult a doctor about whether the exercise regimen is appropriate. It can be helpful to provide them with a list of ingredients for the specific workout you’re looking at.
