5-ALA phosphate is the “code” for cellular energy metabolism.
Do you often feel exhausted? Struggled with blood sugar issues for years? Or perhaps you’re seeking anti-aging solutions and vibrant health? Today, let’s explore a powerful “energy key” hidden deep within our cells—5-ALA. This compound is not only Japan’s latest health craze but also a hot topic in advanced medical research, holding remarkable potential!
PART 01
What is 5-ALA?
5-Aminolevulinic acid (5-ALA), also known as δ-aminolevulinic acid, is a non-proteinogenic functional amino acid widely found in nature—in plants, animals, bacteria, and fungi. It is a precursor for the biosynthesis of tetrapyrrole compounds such as chlorophyll, heme, and cytochromes.

5-ALA Biosynthetic Pathways
In living organisms, 5-ALA is mainly synthesized via two natural pathways:
C4 Pathway (Shemin Pathway): Predominant in animals, yeast, certain protozoa, and purple non-sulfur photosynthetic bacteria. This pathway uses glycine and succinyl-CoA as substrates, catalyzed by the key enzyme 5-aminolevulinic acid synthase (ALAS), to form 5-ALA. ALAS is the rate-limiting enzyme and is strongly inhibited by heme through feedback regulation.
C5 Pathway (Beale Pathway): Found mainly in higher plants, algae, and many bacteria. This pathway begins with glutamate and proceeds through three enzymatic steps:
- Glutamyl-tRNA synthetase (GluTS) links glutamate to a specific tRNA, forming glutamyl-tRNA.
- Glutamyl-tRNA reductase (GluTR), with NADPH, reduces glutamyl-tRNA to glutamate-1-semialdehyde (GSA).
- Glutamate-1-semialdehyde aminotransferase (GSA-AM) converts GSA into 5-ALA.
GluTR is the key rate-limiting enzyme of this pathway and is also regulated by heme.

Biological Functions of 5-ALA
(1) Master of Blood Sugar Management
When used in combination with other anti-diabetic medications, 5-ALA improves glucose metabolism by enhancing glucose oxidation in the TCA cycle, reducing insulin resistance and lowering HbA1c levels, thus reducing complications.
(2) Energy Metabolism Enhancer
By promoting heme biosynthesis and enhancing cytochrome C activity, 5-ALA accelerates mitochondrial oxidative phosphorylation, improves ATP production efficiency, boosts mitochondrial function, and alleviates fatigue while enhancing basal metabolism.
(3) Anti-inflammatory and Iron Balance Regulator
5-ALA significantly upregulates the expression of heme oxygenase-1 (HO-1), which has strong anti-inflammatory effects and maintains heme metabolism balance. What does HO-1 do?
- Breaks down heme to produce biliverdin (a strong antioxidant), carbon monoxide (CO, an anti-inflammatory messenger), and free iron.
Triple Effects:
1. Antioxidant: Biliverdin → Bilirubin, which powerfully eliminates free radicals.
2. Anti-inflammatory: CO inhibits pro-inflammatory factors like TNF-α and IL-6, regulating the NF-κB pathway.
3. Iron Recycling: The released iron is reused to synthesize new heme, maintaining iron homeostasis. This plays a vital role in chronic inflammation and immune regulation.

Applications
Health & Wellness – A Rising Star
As a nutritional supplement, 5-ALA phosphate helps activate mitochondria and improve cellular energy metabolism. This contributes to better blood sugar control (smoother post-meal glucose levels) and reduces fatigue at its root, enhancing overall vitality. In 2015, 5-ALA phosphate was approved as a health food ingredient in Japan.
Medical Field – A Cancer “Sniper” Using Light
As a second-generation photosensitizer, 5-ALA is used in photodynamic therapy (PDT), a standard cancer treatment. Here’s how it works:
- External or oral 5-ALA is metabolized into protoporphyrin IX (PpIX) inside cancer cells.
- Exposure to specific wavelengths of light causes PpIX to produce reactive oxygen species (ROS), which selectively destroy cancer cells via apoptosis or necrosis.
Cosmetics – Deep-Penetrating “Moisture Elf”
Due to its very small molecular size (about 1/100th that of collagen, 1/10,000th that of hyaluronic acid), ALA easily penetrates the skin. It is added to serums and creams for deep hydration and to support skin health.
Agriculture – A Green Catalyst for Crop Yield
As a precursor to chlorophyll and other tetrapyrroles, 5-ALA increases chlorophyll content, enhances photosynthetic efficiency, and promotes the synthesis of soluble sugars and carbohydrates in plants, leading to sweeter, more colorful, and higher-yield crops.
PART 05
Conclusion
5-ALA phosphate is the “code” for cellular energy metabolism. It significantly reduces fatigue, stabilizes postprandial blood glucose, and enhances physical endurance. As a star ingredient in Japan’s health market, it is emerging as a revolutionary force in anti-aging and metabolic wellness. Keep your eye on 5-ALA—it may be the key to unlocking your full life energy potential.
