Our Verdict
Influencer-driven brand, not a quality leader. Bloom Nutrition is a celebrity-backed wellness brand (founded by Mari Llewellyn) that has expanded into colostrum on the back of TikTok marketing. The product itself doesn't disclose IgG content, doesn't specify third-party testing details, and doesn't make verifiable sourcing claims. It exists because the colostrum trend exists, not because the formulation is differentiated. Cheaper alternatives with better transparency are available.
