However, there are certain factors that may affect the duration of the effect of pre workouts. Here are some of them:

  • Fatigue

  • Poor Nutrition

Keep in mind that supplements are designed to supplement your diet not provide it. Because of this, it is expected that your supplements will be at its optimum performance when your body is properly nourished. Proper nutrition can also maximize the absorption of the ingredients of the supplements, making it more effective.

  • Fullness Of Stomach

  • Dehydration

Keep in mind that it is water that delivers nutrition from one part of the body to the other. If your body is not properly hydrated, the effects of your pre-workout supplements will be diminished.

  • Amount Of Caffeine In The System

When you consume too much caffeine, there is a tendency that you will body will crash and you will feel exhausted instead of energized. As a result, your body will find it difficult to absorb and enjoy the benefits of pre-workout supplements.

  • Time Of Workout

As a rule of thumb, you should take your supplements 30-45 minutes before working out. If you take too long to workout after taking your supplements, the effects of the supplement will wear off without you maximizing its benefits.

How To Tell If Your Pre-Workout Is Still Working

If this is the case, how would you know if your workout still has an effect on your body? Well, there are some signs that you should watch out for. Here are some of them:

  • You Are Still Energized And Focused

The main reason why people take pre workout supplements is so that they can enhance their focus and boost their energy. If you still feel mentally focused and energized to perform your workouts, it means that the supplement still has an effect on your body.

  • You Feel A Tingling Sensation

If your supplements contain beta alanine, it will create a tingling sensation—as if your body is being pricked (softly, though) by pins and needles. Some would even refer to this sensation as an itching and burning sensation which is totally safe and normal as this is caused by the nerve endings underneath our skin that have been overstimulated by the supplements.
