Integrative Therapeutics

Traditionally, Integrative Therapeutics sold exclusively through licensed healthcare professionals (physicians, naturopaths, functional medicine practitioners). Today, most SKUs are also available through Amazon and third-party retailers without a prescription. However, the brand still recommends professional supervision, especially for condition-specific products like Cortisol Manager or SBI Protect, because dosing and selection decisions benefit from clinical guidance.

Yes — Integrative Therapeutics has a 45-year track record as a practitioner-trusted brand. Since its 1979 founding and its 2014 acquisition by Schwabe Extracta (one of the world's largest herbal medicine manufacturers), the brand has maintained GMP-certified manufacturing, science-backed formulations, and a professional-channel distribution model that self-selects for clinicians who demand quality evidence for their patients.

Cortisol Manager combines Ashwagandha (Sensoril standardized extract), Phosphatidylserine, and L-Theanine to modulate the cortisol stress response and support sleep onset. Clinical evidence for Ashwagandha at standardized doses is solid (KSM-66 and Sensoril both have RCT support), and Phosphatidylserine has strong evidence for blunting exercise-induced cortisol. It's one of the brand's most clinically credentialed products.

SBI Protect delivers 500mg of serum-derived bovine immunoglobulins (secretory IgG) per serving — a unique ingredient that binds and neutralizes gut pathogens, supports gut-barrier integrity, and modulates intestinal immune activity. It's primarily used under practitioner guidance for leaky gut, IBS, inflammatory bowel concerns, and post-antibiotic gut restoration. It is not a standard probiotic — it works via immune-passthrough rather than bacterial colonization.

The key differences are formulation intent and channel. Integrative Therapeutics designs products to meet clinical scrutiny — licensed healthcare professionals will not recommend products that under-dose or use proprietary blends they can't justify to patients. This drives the brand to use clinically researched doses, disclose ingredient amounts, and maintain GMP manufacturing. Retail brands are optimized for shelf presence and price; Integrative Therapeutics is optimized for clinical defensibility.
