Kratom (Mitragyna Speciosa) is popular among athletes, workout enthusiasts, and bodybuilders. This plant is used to treat pain and anxiety, but also works as a pre-workout supplement and post-workout recovery aid.
Unlike conventional formulas that are based on artificial stimulants, kratom offers a unique pharmacological profile that combines adrenergic stimulation for energy enhancement, opioid receptor modulation for tolerating pain, and serotonergic effects for mood improvement.
Before diving further into working out with kratom, let’s understand how it works first.
How Kratom Affects Exercise Performance?
Kratom interacts with opioid and adrenergic receptors to provide stimulating effects that are similar to caffeine but with smoother energy and no jitters. It provides several benefits for workout enthusiasts, such as increased energy and endurance. It helps you push through tough workouts.
Kratom improves focus and connection between the mind and muscles. It improves your workout efficiency and delays muscle exhaustion, reducing fatigue. Also, it keeps you motivated and improves your mood. Below are the three main effects of kratom on exercise performance:
1. Energy and Endurance Boost
Kratom’s main alkaloid, mitragynine, which holds 60 to 70% of kratom, interacts with adrenergic receptors. This interaction provides stimulant-like effects at low doses. It also increases stamina, delays fatigue, and provides better mind-muscle connection.
In 2022, a survey of 500 athletes found 68% improved endurance when using white or green strains before cardio.
2. Pain Relief and Recovery
Kratom also helps in pain relief by activating mu-opioid receptors, reducing muscle soreness, joint pain, and inflammation, especially in weightlifters. Red strains in 3 to 5 grams are best for post-workout recovery and pain relief.
3. Potential Downsides
Kratom is a mild diuretic that poses a dehydration risk. Tolerance build-up is another potential downside of kratom.
Best Kratom Strains for Different Workouts
1. White Vein Kratom – Best for Cardio & HIIT
White vein kratom is high in Mitragynine and low in 7-hydroxymitragynine, providing energizing effects and focus. This strain is best for cardio, HIIT, and endurance training.
2. Green Malay – Best for Strength Training
Green Malay has moderate mitragynine with minor alkaloids, which makes it a perfect fit for balanced energy and pain relief. This strain is suitable for weightlifting, CrossFit, and functional training workouts.
3. Red Bali – Best for Post-Workout Recovery
Red bali is high in 7-hydroxymitragynine content, which makes it suitable for relaxation and pain relief.
Kratom vs. Traditional Pre-Workout Supplements
Here is a comparison to understand kratom vs. other synthetic pre-workout supplements:
| Factor | Kratom | Traditional Pre-Workout |
| Energy Source | Adrenergic modulation | Caffeine + stimulants |
| Pain Relief | Yes (opioid receptor action) | No (unless contains NSAIDs) |
| Crash | Mild (if any) | Common (sugar/ stim drop) |
| Tolerance | Develops over weeks | Develops rapidly |
| Hydration | Slightly dehydrating | Often contains |
How to Use Kratom Safely for Exercise
1. Dosing Guidelines
| Goal | Strain | Dose | Timing |
| Pre-Workout Energy | White Maeng Da | 1.5-3g | 30 mins before |
| Strength & Focus | Green Malay | 2-4g | 45 mins before |
| Post-Workout Recovery | Red Bali | 3-5g | Immediately after |
2. Hydration & Nutrition Tips
- Always drink 6-8 glasses of water with kratom.
- Add electrolytes in your routine, such as coconut water and LMNT, etc.
- Eat a light meal 1 hour before dosing.
- Do not consume kratom on an empty stomach.
3. Avoiding Tolerance & Dependence
- Cycle usage (3-4x weekly max).
- Rotate strains (prevents receptor burnout).
- Take tolerance breaks (1 week per month)
Potential Risks and Who Should Avoid Kratom
Kratom can cause overstimulation, dehydration, tolerance build-up, and digestive issues; however, you can avoid them by sticking to low and moderate doses, drinking plenty of water, switching between different strains, and avoiding high doses, especially on an empty stomach.
1. When Not to Use Kratom for Workouts
- High-intensity competitions
- Dehydrating environments, such as marathon training or hot yoga.
- Along with other stimulants as it can cause an over-stressed heart.
2. Long-Term Considerations
In the long term, using it can cause dependency risk and a possible testosterone impact.
Conclusion: Is Kratom Worth It for Fitness?
Kratom is beneficial if used with caution. It can be used to boost endurance, reduce post-workout pain in joints, and as an alternative to harsh stimulants or post-workout supplements. Kratom is not a magic pill; proper hydration, dosing, and cycling are required for fitness.
