L-Histidine 500 mg Capsule
Histidine is a semi-essential amino acid that serves as a fundamental building block of proteins in the human body. While adults usually produce adequate amounts, supplementation may be needed during periods of rapid growth, injury recovery, or specific metabolic demands.
It is also the direct precursor to histamine, an important compound involved in the immune response, digestion, and neurological function.
Key Benefits
Tissue Repair & Growth: Supports the maintenance and repair of tissues, including myelin sheaths that protect nerve cells.
Immune System Support: Helps regulate inflammation and supports the production of red and white blood cells.
Joint Health: May help manage symptoms of rheumatoid arthritis, where low histidine levels are often observed.
Digestive Health: Aids in the production of gastric juices, improving digestion and nutrient absorption.
Skin Protection: Helps produce urocanic acid, which provides a natural protective barrier against UV radiation.
How to Use
Standard Dosage: Typically 500 mg to 1000 mg daily for general wellness. Clinical doses should be determined by a healthcare provider.
Timing: Best taken on an empty stomach, ideally 30–60 minutes before meals.
Method: Swallow the capsule whole with a full glass of water.
Cycle: For use beyond 30 days, consider combining with an amino acid complex to maintain nutritional balance.

Frequently Asked Questions (FAQs)
Q: Is Histidine a drug or a supplement?
A: It is usually marketed as a nutritional supplement (nutraceutical). In clinical settings, L-Histidine Hydrochloride may be used in intravenous (IV) nutrition for critically ill patients.
Q: Can Histidine help with allergies?
A: It plays a role in immune function as a precursor to histamine. However, during active allergic reactions, consult a doctor before supplementation, as it may influence histamine levels.
Q: Does it interact with medications?
A: Yes. It may interfere with Levodopa (used in Parkinson’s disease) and may reduce the effectiveness of antihistamines. Always inform your doctor or pharmacist about all supplements you take.
Q: Can I get enough Histidine from diet alone?
A: Most people can obtain sufficient amounts from foods like meat, fish, dairy, soy, and beans. Supplements are typically used for deficiencies or increased physiological demands.
Q: How should I store this supplement?
A: Store in a cool, dry place away from direct sunlight. Keep the container tightly closed to prevent moisture exposure.
