5-HTP 100 mg (Enteric Coated)
This is the best option for users who experience nausea with 5-HTP. The enteric coating ensures the capsule bypasses the stomach and dissolves in the small intestine, preventing the conversion to serotonin in the gut which causes GI distress.
Quality & Materials
High-purity 5-HTP with a specialized enteric coating. The coating is designed to be stable in stomach acid.
Evidence & Testing
The brand utilizes ISURA certification, which uses mass spectrometry to test for over 800 possible contaminants.
Brand Transparency
ISURA third-party verification provides a high level of confidence in the purity of the raw materials.
Value Assessment
Moderately priced ($0.30/serving). The added cost is for the specialized coating technology.
Why Not Alternatives?
Standard 5-HTP capsules often cause stomach upset in up to 30% of users. Natural Factors solves this specific compliance issue where others do not.
