The Power

Recovery is more than just a buzzword. It is a recognized stage of the muscle building process. The fact is, if you aren’t taking recovery seriously, you are never going to reach your full potential. Recovery is so important that several of the leading sports organizations in the world have created panels of specialists to make sure their million dollar athletes are recovering properly and adequately, and Athlean-Rx ReconstruXion has been a part of that conversation.

The Science

6g of Leucine, a whopping 10g of Glutamine, 1.25g of Betaine… These are just the kick off points for this powerhouse of a formula. As always, we put the science in everything we do, and each and every ingredient is thoroughly researched and backed by studies to prove its efficacy as a sports recovery supplement.

The Facts

You asked and we answered with our most potent formulas and open labels so you know exactly which ingredients and how much of each you’re getting. Athlean-Rx contains no proprietary blends, and as always, no fillers, no substitutes and no harmful chemicals.

The Results

ReconstruXion is the go to recovery formula for some of the top teams in pro sports. It’s been so effective with our athletes that we have several reports of it preventing delayed onset muscle soreness (DOMS) after particularly intense workouts. While these reports are anecdotal at this stage I can personally attest to RX3’s effectiveness in helping me battle DOMS.

I use ReconstruXion daily as a recovery aid and to assist in blunting the effects of DOMS after training.

ATHLEAN RX-3 ReconstruXion


ATHLEAN ReconstruXion CONTAINS: 2g


Research suggestions that L-Carnitine L-Tartrate improves muscle recovery and repair times. This is probably due to a boost in nitric oxide (NO) production, which improves blood flow and oxygen consumption in the muscles. LCLT also increases androgen receptors in the muscle cells, which means more testosterone is recruited to build muscle.

  • Improves muscle recovery and repair between training sessions (probably due to a boost in Nitric Oxide and an increase in muscle oxygen consumption)
  • Increases androgen receptors in muscle cells, thereby recruiting more testosterone to build muscle
  • Improves insulin sensitivity



ATHLEAN ReconstruXion CONTAINS: 6g


Considered one of the most anabolic of all the individual amino acids, L-Leucine is considered to be the main activator of protein synthesis via its effects on the mTOR pathway. What makes it especially vital (and often in deficient supply) is that it is an essential amino acid, which means that the body doesn’t produce it naturally. The only way for you to get this key amino acid in your system is through diet and or supplementation. Throw in its additional researched ability to prevent the breakdown of muscle tissue after intense training, and your ability to tip the balance of muscle growth in your favor just grew by leaps and bounds with ReconstruXion.

  • Reduces muscle breakdown caused by intense exercise or dieting
  • Stimulates protein synthesis, which increases the effectiveness of training and speeds recovery time between training sessions
  • May increase metabolic rate



ATHLEAN ReconstruXion CONTAINS: 10g


L-Glutamine is most commonly used for improving healing time following injuries or surgery. It can help speed recovery time between training sessions due to an increase in nitrogen levels in the muscle cells which assists in protein synthesis. L-Glutamine is also recognized for boosting the immune system, increasing energy levels and helping to regulate blood sugar levels.

  • Reduces healing time after injuries or surgery
  • Increases nitrogen levels in the muscle cells to assist in protein synthesis, which increases the effectiveness of training and speeds recovery time between training sessions
  • Boosts the immune system, which can be compromised by intense training
  • Increases energy levels and helps maintain steady blood sugar levels



ATHLEAN ReconstruXion CONTAINS: 1250mg


One of the most important benefits of Betaine is its ability to improve muscle strength and power during training sessions. Some studies have shown that it can improve endurance, increase the number of reps that can be done with a given weight, and improve power and force with every rep. Evidence also indicates that Betaine improves protein synthesis following training sessions.

  • Improves muscle strength, power and endurance
  • Increases protein synthesis following training sessions
  • Increases growth hormone and insulin-like growth factor 1 production
  • May help promote fat loss



ATHLEAN ReconstruXion CONTAINS: 200mg


L-Theanine is recognized for improving cognitive and mental processing, as well as focus, attention, memory, alertness and mood. It can also help improve sleep quality, reduce stress and help keep the body in a state of relaxation. It also helps improve immune system function, which can become compromised with heavy training.

  • Reduces the effects of stress
  • Increases serotonin and dopamine
  • Improves sleep quality
  • Improves focus, attention, memory, alertness and mood
  • Improves immune system function
  • The most effective dose for Theanine is from 100-250g per day
