N-Acetyl Cysteine - 500 mg, 60 Capsules
N-Acetyl Cysteine (NAC) is a highly bioavailable amino acid precursor providing 500 mg per capsule to significantly boost glutathione levels in deficient individuals. Well-absorbed in the intestinal tract, NAC serves dual roles as both a powerful glutathione precursor essential for immune function and detoxification support, and as a natural mucolytic agent that reduces mucus viscosity for improved respiratory health.
Key Benefits:
- Boosts Glutathione Production – As a direct precursor to the amino acid cysteine, NAC is efficiently absorbed in the intestinal tract and significantly increases glutathione levels, the body's master antioxidant essential for cellular protection, immune function, and detoxification capacity
- Essential Detoxification and Immune Support – Particularly important for individuals with special needs who require extra support for immune and detoxification systems, helping the body eliminate toxins, protect against oxidative stress, and maintain optimal cellular health
- Natural Mucolytic Properties – Functions as a natural mucolytic agent that reduces the viscosity (thickness) of mucus, supporting respiratory health, sinus function, and helping clear nasal passages for improved breathing and comfort
- Versatile Administration Options – Convenient 500 mg capsule format that can be swallowed whole or opened and mixed into food or juice, making it easy to customize dosing and suitable for both adults and children as directed by healthcare practitioners

Product Details
Understanding Serotonin and Emotional Balance
Serotonin is a crucial neurotransmitter that plays a vital role in regulating multiple aspects of daily wellness. As the body's primary mood-regulating chemical messenger, serotonin influences emotional balance, sleep quality, and appetite control. Our 5-HTP supplement provides L-5-Hydroxytryptophan, the direct precursor to serotonin, offering nutritional support for the body's natural neurotransmitter production processes. This targeted approach helps maintain optimal serotonin levels, which are associated with a balanced emotional state and overall sense of wellbeing.
Natural Sleep Support Through Melatonin Synthesis
Beyond its role in mood regulation, serotonin serves as the precursor to melatonin, the hormone that governs your body's sleep-wake cycle. By supporting healthy serotonin levels, 5-HTP helps facilitate the natural production of melatonin, promoting more consistent sleep patterns and improved sleep quality. This dual-action benefit makes 5-HTP a comprehensive solution for those seeking to support both daytime emotional wellness and nighttime rest without the use of synthetic sleep aids.
Appetite Regulation and Healthy Eating Patterns
Serotonin functions as a natural satiety signal in the brain, playing an important role in regulating food intake and eating behavior. When serotonin levels are adequately supported, the body's natural appetite control mechanisms work more effectively, helping you maintain balanced eating patterns and supporting overall nutritional wellness goals. This makes 5-HTP a valuable addition to a comprehensive approach to healthy weight management.
Quality, Purity, and Peace of Mind
Each vegetarian capsule contains 50 mg of pharmaceutical-grade 5-HTP extracted from Griffonia simplicifolia seeds and is certified to be free of Peak X, an unwanted compound sometimes found in lower-quality 5-HTP products. Our formula is manufactured under strict Good Manufacturing Practices (GMP) with third-party quality certifications, ensuring you receive a pure, potent product. This supplement is vegan, non-GMO, and free from common allergens including gluten, dairy, soy, and artificial colors or preservatives.
Suggested Use
Suggested Use: Adults: Take 1 capsule, 1 to 2 times daily or as directed by a healthcare professional. Children: As directed by a healthcare professional.
Caution: Consult with your physician if you are pregnant or nursing, have a medical condition, are taking prescription drugs (particularly psychiatric medications), or are under the age of 18 years. Do not use concurrently with antidepressants. KEEP OUT OF REACH OF CHILDREN.
