Klaire Labs was founded in 1969 in the United States as one of the first hypoallergenic supplement companies, created to serve people with sensitivities who needed formulas free from common allergens and unnecessary excipients. Today the range is produced by SFI Health in cGMP-certified facilities, with raw-material identity and purity testing and a practitioner-only heritage that has kept its formulations clinically focused rather than trend-led. That transparency-first philosophy, where every active and every excipient is declared and the simplest effective formula is preferred, is exactly the approach Welzo looks for. Welzo's healthcare professionals assessed the brand for alignment with our standards and found its labelling, allergen controls and manufacturing documentation consistent with our commitment to clear, quality-led nutrition. Klaire Labs 5-HTP 100 mg earns its place in Welzo's amino acid range through clean sourcing and honest labelling. The 5-HTP is extracted from Griffonia simplicifolia seed, the recognised botanical source, and the amount per capsule is stated plainly rather than hidden in a proprietary blend. The capsule carries only three excipients and is free from the allergens, yeast, corn and GMO ingredients that practitioners most often need to avoid, and the label carries clear drowsiness and medication cautions. The 100 mg strength gives practitioners a straightforward single-capsule option, which reinforces our trust in their quality philosophy.
