Glycyl-Alanyl-Lysine-L-Isoleucine
Glycyl-Alanyl-Lysine-L-Isoleucine (GALI) is a specialized peptide chain known as a tetrapeptide. It consists of four specific amino acids: Glycine, Alanine, Lysine, and Isoleucine. While this sounds like a complex chemical name, it essentially represents a specific building block sequence found in the proteins of the foods you eat. This ingredient is primarily researched for its potential role in supporting cellular health and metabolic balance. It is categorized as a dietary supplement, often marketed for its potential to support energy levels and tissue repair. Think of it as a very specific instruction manual sent to your body's cells to help optimize their function and resilience.

Health Benefits & Sources
Why You Need It
- Cellular Repair: Supports the body's natural ability to repair tissues.
- Metabolic Support: Helps regulate energy production within cells.
- Antioxidant Potential: May help reduce oxidative stress.
Deep Dive
Glycyl-Alanyl-Lysine-L-Isoleucine (GALI) is a synthetic peptide, but its power lies in how it mimics natural biological processes. The amino acids it comprises are essential (meaning your body can't make them efficiently from scratch).
- Tissue Regeneration: Glycine and Alanine are heavily involved in creating collagen and elastin. By providing this specific sequence, GALI supplements may encourage faster recovery of muscles and skin after stress or injury.
- Energy Efficiency: Isoleucine is a branched-chain amino acid (BCAA) critical for muscle metabolism. In this peptide form, it may be absorbed more efficiently, helping your body utilize glucose for energy more effectively, potentially reducing feelings of fatigue.
- Immune Defense: Lysine is vital for antibody production. Studies suggest that specific peptide sequences can enhance the body's immune response by supporting the production of white blood cells.
Natural Food Sources
Since GALI is a sequence of amino acids, the best way to get it is by eating high-quality protein sources. Your digestive system naturally breaks these foods down into amino acids and reassembles them into the peptides your body needs.
| Food | Amount | % DV (Amino Acid Profile) |
|---|---|---|
| Chicken Breast | 3 oz | ~35% |
| Salmon | 3 oz | ~30% |
| Eggs | 2 large | ~25% |
| Greek Yogurt | 1 cup | ~20% |
| Almonds | 1 oz | ~15% |
Supplementation
This specific peptide sequence is rarely found in food directly; it is usually taken as a synthesized supplement for targeted therapeutic effects.
- Typical Dosage: Research suggests dosages between 50mg to 150mg daily, often taken on an empty stomach for better absorption.
- Who Should Take It: Athletes looking for recovery aids, individuals under high stress, or those seeking specific metabolic support. It is not a replacement for a balanced diet.

Frequently Asked Questions
No. Peptides like GALI are chains of amino acids found in animal and plant proteins. You get the building blocks from eating protein-rich foods, not fruits or veggies directly.
Most experts suggest cycling amino acid supplements (e.g., 8 weeks on, 2 weeks off) to maintain your body's natural sensitivity to them.
Absolutely not. It is a peptide (a short chain of amino acids), which is a natural nutrient, completely different from anabolic steroids.
For metabolic support, some users report feeling effects within 2 weeks. For tissue repair, consistent use for 4-6 weeks is usually recommended.
Safety & Side Effects
Glycyl-Alanyl-Lysine-L-Isoleucine is generally considered safe for healthy adults at recommended dosages. However, because it is a concentrated amino acid peptide:
- Kidney Strain: Individuals with pre-existing kidney conditions should avoid high-protein peptides, as the kidneys must filter out nitrogen waste from amino acid metabolism.
- Pregnancy/Breastfeeding: There is insufficient data on safety during pregnancy; consult a doctor.
- Drug Interactions: It may interact with medications that affect nitrogen balance (like certain steroids).
Side Effects: Mild gastrointestinal upset (nausea, bloating) is the most common side effect if taken without food.
