Overview
- In new analyses published Nov. 10–11, Dr Rachel Woods reports no strong, large-trial evidence that colostrum supplements improve immunity, digestion, or skin in healthy adults.
- Wellness brands, including Kourtney Kardashian Barker’s Lemme, promote colostrum to adults with promises of immune support, gut health, and glowing skin.
- Studies cited for benefits are small and context-specific, such as transient intestinal permeability after intense exercise or NSAID use, and do not generalize to everyday health.
- Several products add vitamin D and prebiotic fibers like inulin or xylooligosaccharides, which have independent evidence and may better explain any perceived effects than colostrum itself.
- Marketing terms like “clinically studied” do not mean “clinically proven,” standard supplement disclaimers apply, and consumers are urged to scrutinize labels and consult health professionals.
