Sports Research® Bovine Colostrum Powder – Easy to Mix, Single Ingredient Superfood – Immunity Support & Gut Health w/IgG Antibodies - U.S. Sourced · Non-GMO · Gluten Free - 75 Servings (Unflavored)

Clinical trials typically use Clinical studies typically use 20–60g/day for gut permeability; 2g/day is within traditional wellness-use range but below high-dose therapeutic protocols. Sports Research Bovine Colostrum Powder delivers 1 scoop (2g) mixed in cold liquid daily, which we classify as Traditional relative to that range.

Bovine colostrum at 2g/day has a very low interaction profile with most medications. The growth factors in colostrum (IGF-1, TGF-β) are generally degraded in the digestive tract at this dose. Individuals on immunosuppressant medications should consult a physician before use, as colostrum's immune-modulating immunoglobulins may theoretically interact. No established drug interactions are documented in clinical literature for low-dose colostrum supplementation.

Bovine colostrum is well-tolerated in studies up to 8 weeks at doses of 10–60g/day — the 2g used here is extremely conservative by comparison. Mild digestive adjustment (loose stools or bloating) can occur in the first week, particularly in dairy-sensitive individuals. No significant adverse events have been documented with long-term daily use at wellness doses. Individuals with known cow's milk allergy should avoid this product entirely.

A small percentage of users experience mild GI effects (bloating, loose stools) in the first 1–2 weeks as the gut adjusts to immunoglobulins and growth factors. Starting with half a scoop for the first week can reduce adaptation discomfort. Because this is a dairy-derived product, individuals with lactose intolerance may experience symptoms — though colostrum contains less lactose than standard dairy.

Bovine colostrum powder mixes well with most supplement protocols — it is commonly added to protein shakes, pre- or post-workout beverages, or alongside probiotic regimens. Sports Research specifically recommends consuming it in cold liquids to preserve bioactive integrity. Avoid mixing with hot beverages, which can denature the immunoglobulins and lactoferrin. No supplement interactions are known at the 2g/day dose.

Mix one scoop (2g) in 6–8 oz of cold water, juice, or a cold protein shake. Do not add to hot beverages — heat above 40°C (104°F) can denature the bioactive proteins including IgG and lactoferrin, reducing their effectiveness. Store the powder in a cool, dry place with the lid sealed. Those with dairy allergies or cow's milk protein allergies must avoid this product.

Gut-integrity benefits from colostrum — including tighter intestinal junctions and reduced permeability — typically require 4–8 weeks of consistent daily use based on clinical studies. Immune modulation effects (IgG-mediated) are similarly gradual. At the 2g/day dose used in this product, the timeline to perceive noticeable benefits may be longer than in higher-dose clinical protocols. Users tracking gut health should maintain consistent daily use for at least 60 days before evaluating outcomes.
