Instant Leucine Powder

As a branched-chain amino acid (BCAA), Leucine is believed to play a vital role in protein synthesis and the promotion of muscle mass growth. Instant leucine in protein shake products is also useful in improving energy levels and enhancing overall workout performance.

What is L-Leucine?

L-leucine is among the nine essential amino acids which are important in the maintenance of vital bodily processes. It is one of the BCAAs, along with isoleucine and valine, which are significant in slowing down the degradation of muscle tissues. According to studies, L-leucine is also the most important ketogenic amino acid among humans.

The CAS number of L-leucine is 61-90-5. Its molecular formula is C6H13NO2 and its molecular weight is 131.17g/mol. It has a whitish powder appearance.

L-Leucine Specifications

The L-leucine powder is offered in the dietary supplements market in two forms-standard leucine or instant leucine.

On one hand, standard form Leucine often refers to the compound that is not yet added with lecithin as a surfactant. Hence, when dissolved in water, it creates a layer on top, making it difficult to swallow. This is proven in both scientific research studies and customer reviews on standard leucine supplements.

On the other hand, Instant leucine powder is a Leucine form that is added with a surfactant known as lecithin. This product typically gets 5 stars in many reviews as compared to standard form leucine as it is ordinarily easy to swallow and readily dissolvable in water.

Typically, bulk purchases of the compound are packed in paper drums and two layers of poly bags inside. Paper drums usually contain 25 kilograms of the product.

Instant Leucine vs. Standard Leucine

While both instant leucine and standard form leucine provide almost similar health benefits in terms of protein synthesis and overall nutrition, they possess certain distinguishing features which are relevant in choosing the right dietary supplement ingredient.

Both instant leucine and standard leucine are soluble in water. However, due to its surfactant content, Instant leucine dissolves faster than standard leucine. Hence, in making protein shakes and juice products for workouts, instant leucine is the premium choice as shown in customer reviews.

Due to its easy dissolvability, some experts believe that instant leucine may have better bioavailability when compared to standard leucine. In effect, as per experts’ advice, the use of instant leucine may be more beneficial than standard leucine is it may provide health benefits more efficiently. Further in-depth reviews are still being conducted to verify this claim.

The price for a kilogram of instant leucine usually ranges from $8-$16 kilograms. Conversely, standard leucine is usually sold at a range of $8 to $14 per kilogram.

Leucine vs. Isoleucine

In terms of molecular formula, there is no significant distinction between Leucine and Isoleucine as the latter is an isomer of the former. However, distinctions can be marked on their individual chemical structures.

While both amino acids are essential for muscle growth and protein synthesis, in-depth studies conducted to fully understand the said BCAAS have shown that isoleucine consumption may contribute to the development of certain metabolic conditions such as Methylmalonic acidemia (MMA) and propionic acidemia (PA). Persons who develop MMA or PA are advised not to take food products with isoleucine.

Leucine vs. BCAAS

In general, branch-chained amino acids are vital in the regulation of essential body processes such as energy production, breakdown, and absorption of nutrients, as well as physiologic responses to stress.

Among the three essential BCAAs for optimum health, there is no doubt among experts that L-leucine is the most useful for body muscle growth. Thus, L-leucine is the most popular BCAA used in the formulation of workout supplements and nutrition protein shakes for optimum wellness.

How does L-Leucine Work?

Essentially, L-leucine works by activating pathways to protein synthesis which, in turn, results in the growth and development of muscle tissues in various muscle regions. Typically, the branched-chain amino acid L-leucine is administered to prevent muscle tearing and deterioration not only among athletes and bodybuilders but also among customers who are at risk of injuries due to underlying medical conditions affecting the musculoskeletal system.

Manufacturing Process

L-leucine is produced from culturing microorganisms which include strains of Brevibacterium and Corynebacterium. The said microorganisms are subjected to conventional mutagenesis using a conventional medium such as carbon sources and nitrogen sources. Generally, the process of culturing is done in aerobic conditions, with pH maintained at 5 to 9. Precipitates after culturing are thereafter removed through centrifugation and the L-leucine is obtained through methods including salting out.

L-leucine Benefits

Leucine is an essential post-workout and pre-workout supplement ingredient that is highly preferred by many customers. It provides the following effects, among others:

  • It promotes protein synthesis.

Muscle protein synthesis is an important process in the body that occurs in response to damage in certain muscle groups. It is also an important factor to negate muscle protein breakdown which results from the performance of physical activities. By supporting pathways to protein synthesis, experts say that the intake of L-leucine may help promote the process.

  • It promotes lean muscle growth and repair.

Protein synthesis eventually results in the development of new muscle fibers and the growth of lean muscle groups. Thus, L-leucine is ideal for bodybuilding.

Leucine Dosage

The recommended dosage for short-term Leucine supplementation is around 3 to 4 grams per day. This applies to inactive individuals. However, persons who are engaged in extensive physical activities are advised to take larger doses depending on the recommendation of their physician.

Factors including age, overall physical condition, and weight are also being considered in the determination of the ideal dosage for Leucine supplementation.

L-Leucine Side Effects

Based on product description, verified scientific studies, and individual customer reviews, L-leucine supplementation may result in side effects including abdominal discomfort, nausea, and vomiting.

Individuals who experience unusual adverse effects such as sudden confusion, changes in behavior, and symptoms involving the cardio-respiratory system are advised to consult their physicians immediately.
