What is Leusine? 

Leucine is one of the essential amino acids, which are the most basic building blocks of protein molecules. It plays a crucial role in stimulating muscle synthesis and is essential for muscle health. Leucine acts as a catalyst in promoting muscle growth and is effective in muscle strengthening. Unlike other protein components, it is directly metabolized in the muscles without passing through the liver. While leucine is a core essential amino acid for protein synthesis, it is not produced within the body and must be obtained through direct consumption.

Among the branched-chain amino acids (BCAA), leucine is one of them and serves a central role in protein synthesis. It is used as fuel in situations involving intense or prolonged physical exertion, and it is the most abundant BCAA found within muscle tissues.

1. Pure 99.8% Leucine (L-Leucine)
- High-purity intake of leucine, one of the BCAA components and essential amino acids.
- Leucine is not produced within the body, so it can be conveniently consumed through food or supplements.

2. Balanced Protein Incorporation with Plant-Based and Animal-Based Proteins
- Includes isolated soy protein, sheep milk powder, concentrated whey protein, and whey protein isolate, along with leucine.

3. Complex Blend of Energy Sources for Vitality
- L-Arginine, Boswellia extract powder, Maca extract powder, Niacinamide, Taurine, BCAA (Isoleucine, Leucine, Valine), Blackberry extract powder.

4. Expert Formulation Know-How from Dr. Lyuh Esther
- Dr. Esther: Preventive Medicine Ph.D. from Seoul Medical School, Family Medicine Specialist.
- Development of ingredient combinations considering the physiology and health of Koreans.

5. Safe Food Produced by a Ministry of Food and Drug Safety (MFDS) HACCP Certified Manufacturer
- Processed safely in a manufacturing facility certified with HACCP, ensuring strict and systematic hygiene and quality control.

- Those who find it inconvenient to consume powdered protein and struggle with consistent protein intake 
- Those engaged in strength training exercises 
- Those who require protein absorption before and after workouts 
- Those concerned about the loss of muscle strength and muscle mass 
- Those in need of protein intake due to irregular eating habits 
- Those seeking maximum effectiveness with a small amount of protein

Additional intake of a small amount of leucine results in the same level of protein synthesis as a large amount of protein
