NK-Stim
Ortho Molecular Products
Overview
NK-Stim provides a blend of ingredients known for their immune-modulating properties. The inclusion of Zinc at a clinically effective dose is a strong point. Arabinogalactan is also included in a research-backed dose for its immune benefits. However, the precise roles and synergistic effects of Olive Leaf Extract and Aloe Vera Leaf Gel Extract in this specific immune support context, and their optimal dosing for this purpose, are less clearly defined.
The Good
Provides clinically effective dose of Zinc for immune support.
Arabinogalactan dose contributes to immune modulation, particularly reducing common cold incidence.
Includes ingredients with antioxidant and anti-inflammatory properties (Olive Leaf, Aloe Vera).
The Bad
The dosage for Arabinogalactan (610mg per serving, 1220mg daily based on suggested use) is below the minimum effective dose of 4.5g/day (4500mg) for significant cold reduction, potentially limiting its immune-boosting efficacy for this specific benefit.
While Olive Leaf Extract (400mg per serving, 800mg daily) and Aloe Vera Leaf Gel Extract (130mg per serving, 260mg daily) have known benefits, their specific contribution at these doses to overall immune function as touted by the product may not be as robustly supported as for Zinc or Arabinogalactan.
Lack of specific information on the percentage of active compounds (e.g., oleuropein in Olive Leaf Extract) makes it difficult to fully assess potency.
Is it for you?
Best For: Individuals seeking immune support, those interested in NK cell activity enhancement
Skip If: You are pregnant, nursing, or have a known medical condition without consulting a doctor.
