Integrative Therapeutics was founded by healthcare professionals committed to creating clinical-grade nutritional supplements backed by published research and designed for use by integrative and functional medicine practitioners. Their formulas use scientifically validated ingredients at therapeutic doses — no proprietary blend hiding, no filler ingredients, no marketing-driven formulations. Integrative Therapeutics is particularly respected for their GI health line, including Similase digestive enzymes, Physicians Formula supplements, and Cortisol Manager, which has become a go-to formula for HPA axis support. All manufacturing is performed in a cGMP-certified facility and products undergo rigorous third-party testing for identity, potency, and purity.
