Amino9® Essential Amino Acids

6,700 mg

A comprehensive blend of nine essential amino acids clinically proven to rapidly enhance muscle protein synthesis, recovery, and muscle growth.

Amino9® Essential Amino Acids

L-Citrulline Malate 2:1

2,000 mg

Citrulline is a watermelon-derived amino acid that boosts nitric oxide production, increases muscle pumps, enhances endurance, and promotes efficient nutrient delivery to working muscles.

L-Citrulline Malate 2:1

Taurine

2,000 mg

Taurine is a sulfur-containing amino acid that enhances mental clarity, reduces muscle fatigue, and optimizes muscle hydration during intense training.

Taurine

BetaPure™ Betaine Anhydrous

1,250 mg

Naturally found in sugar beets, betaine supports cellular hydration by regulating fluid balance and promotes blood flow by regulating homocysteine levels.

BetaPure™ Betaine Anhydrous

Amino9® Essential Amino Acids

6,700 mg

Of the 20 amino acids necessary for protein synthesis in humans, nine are nutritionally “essential” since the body cannot make them on its own. Hence, we must consume these nine amino acids in the diet for proper health, recovery, and performance. 

The nine EAAs in our intra-workout supplement include:

  • Histidine
  • Isoleucine (BCAA)
  • Leucine (BCAA)
  • Lysine
  • Methionine
  • Phenylalanine
  • Threonine
  • Tryptophan
  • Valine (BCAA)

Taking essential amino acids before, during, and/or after exercise can help rapidly increase muscle protein synthesis with minimal digestive assistance since the amino acids are not bonded together like they are in protein [1]. In fact, one study found that a bolus of leucine-enriched EAAs after a workout stimulated protein synthesis as effectively as intact whey protein despite each supplement providing the same proportions of essential amino acids [2].

Amino9® Essential Amino Acids

L-Citrulline Malate 2:1

2,000 mg

L-citrulline is an amino acid naturally found in watermelon that plays an important role in kidney function and nitric oxide production (which mediates blood flow)[3, 4]. 

By increasing nitric oxide production, L-citrulline enhances blood flow to muscle tissue during exercise, allowing nutrients (e.g. amino acids) and oxygen to replenish muscle tissue more efficiently. Ultimately, this translates to greater muscle pumps and heightened energy levels.

L-Citrulline Malate 2:1

Taurine

2,000 mg

Taurine is a non-proteinogenic amino acid often considered essential to pre-workout supplementation due to its diverse benefits for athletes and gym-goers. For one, taurine is a potent nootropic that promotes focus and attenuates brain cell inflammation and oxidative stress [5, 6].

Taurine can also enhance physical performance via increased blood flow to skeletal muscle tissue [7, 8]. 

Greater blood flow to muscle tissue encourages a favorable milieu for muscle function and recovery during training. Additionally, taurine supplementation has been shown to improve performance in endurance athletes [9].

Taurine

BetaPure™ Betaine Anhydrous

1,250 mg

Betaine, also referred to as trimethylglycine, is a derivative of endogenous choline metabolism, and it naturally occurs in plant species (especially sugar beets). In recent years, betaine has become a common ingredient in pre-workout supplements due to its promise of enhancing athletic performance through diverse mechanisms [10, 11].

For one, betaine is an osmolytic compound that promotes cellular hydration, maintaining cellular volume and water balance during exercise. Betaine is also a crucial methyl donor for several biologically important molecules and a regulator of homocysteine levels, the latter of which is postulated to boost blood flow during training [12].

BetaPure™ Betaine Anhydrous

L-Tyrosine

1,000 mg

L-tyrosine is a conditionally essential amino acid and precursor to dopamine and norepinephrine, two neurotransmitters that govern motivation and reward. Research shows that supplementing with L-tyrosine can significantly enhance cognitive performance and increase alertness, especially under acute stress (such as intense training) [13].

 L-tyrosine has also been shown to improve “cognitive flexibility,” suggesting it can help us adapt to dynamic cognitive demands without letting extraneous thoughts undermine our focus [14].

L-Tyrosine

Coconut Water Powder

1,000 mg

Coconut (Cocos nucifera) water is one of the best natural sources of electrolytes and trace minerals, making it an excellent source of hydration. Coconut has been shown to provide a wealth of general health benefits, including, but not limited to [15]: 

  • Rehydrating the body
  • Fighting inflammation
  • Balancing blood glucose and insulin levels
  • Promoting immune function
  • Enhancing eye and skin health
  • Supporting kidney function
Coconut Water Powder

Electrolytes

415 mg (combined)

Transparent Labs Intra EAA is rounded out with essential electrolytes for hydration and workout performance, including chelated magnesium and calcium, along with sodium and potassium (from Himalayan rock salt and potassium chloride, respectively).

Electrolytes are lost through sweat during exercise, so replenishing them is a must for maintaining fluid balance in the body [16]. These minerals are also integral for muscle contraction, reducing muscle cramps, and the transmission of nerve impulses [17].

Electrolytes

ElevATP®

150 mg

ElevATP® is a clinically researched combination of “ancient peat” (fossilized plants) and apple skin extracts. Using innovative biotechnology, elevATP® stimulates your body’s endogenous production of adenosine triphosphate (ATP), the veritable energetic currency of cells.

By boosting ATP production, ElevATP® can help promote athletic performance (e.g. max strength) and improve body composition [18, 19]. ElevATP® is also a fast-acting ATP booster that starts working from the very first dose [20].

ElevATP®

Astragin™

50 mg

Astragin™ is a water-soluble extract of Panax notoginseng and Astragalus membranaceus, two promising adaptogenic herbs with longstanding medicinal use [21]. The constituents in these plants are suggested to selectively increase the absorption of molecules, such as amino acids, by enhancing intestinal permeability [22]. 

In other words, Astragin™ helps your body absorb the other ingredients in this intra-workout supplement, making the overall formula more effective.

I wish I had a product to review

I have enjoyed TL products, from the Bulk to the Intro to the protein bars. While I told the team I would share with them privately what I am about to share, TL sent me this review request. I don't have a product to review. I ordered it three weeks ago and still have not received it. I contacted TL and they said they sent me another one. This is the third time I have ordered direct from TL and it takes weeks to get their product if they get the order right. The last order, they sent the wrong items to my house. They corrected it but it also took weeks. If you like TL as I do, DON'T BUY DIRECT. Order on Amazon or try to find their products at a store like the Vitamin Shop. They problem is those places don't carry every TL product or flavor. I hope TL can work out their distribution problems or I hope they can build a better supply chain to get their products out in the market. Otherwise, I will continue to find alternatives which they have forced me to do by not delivering on their promise. While I am also grateful they responded to my request, the have never gone that extra mile to ensure customer satisfaction -- Truly a disappointment.

Frequently Asked
Questions

What is an Intra Workout supplement?

Intra-workout supplements are intended to help sustain exercise performance while you're training. These formulas typically contain essential amino acids and other ergogenic ingredients that hydrate the body, promote muscle recovery, and enhance strength and endurance.

Does Intra EAA give you energy?

Technically, our intra-workout formula provides energy in the form of calories from essential amino acids, but that is not their primary ergogenic mechanism of action. However, other ingredients in this formula, like elevATP®, can increase cellular ATP production, conferring an "energy-boosting" effect.

Who should take an Intra Workout supplement?

Intra-workout supplements are suitable for active individuals and athletes who want to maximize their performance in the gym and on the playing field. Our intra-workout formula is an exceptional alternative to traditional sugar-laden sports drinks that provide little else than electrolytes.

Does this product contain caffeine?

We didn't include caffeine in our intra-workout supplement since we offer several pre-workout supplements that contain caffeine. We wanted our pre-workout supplements to be compatible with this formula, and including caffeine would make this problematic due to ingredient overlap.

What's the difference between EAAs and BCAAs?

Branched-chain amino acids (BCAAs) are a subgroup of three essential amino acids: L-leucine, L-isoleucine, and L-valine. While all EAAs are necessary for protein synthesis, the BCAAs are often considered the key regulators of this process [23]. As such, the BCAAs comprise a high proportion of the total EAA content needed to facilitate muscle growth, and our intra-workout supplement reflects this [24].
