Colostrum is nature’s first food after birth—richer and more complex than later milk. This article focuses on the single active ingredient in CHF #40 Colostrum 100 Capsules and what peer-reviewed research has found about bovine colostrum.
Full ingredient list (per capsule): Colostrum (first milking, high IgG) 475 mg. Other ingredients: magnesium stearate, silica, and a gelatin capsule. The label suggests one capsule daily one-half hour before meals. Contains milk (colostrum).
Colostrum is the first fluid mammals produce after giving birth, before mature milk comes in. A 2021 review in Frontiers in Nutrition (Arslan and colleagues) describes bovine colostrum as compositionally distinct from mature milk and rich in proteins, fats, glycans, minerals, vitamins, and bioactive molecules that have been studied for human nutrition applications beyond infancy.
CHF #40 specifies first-milking colostrum with high immunoglobulin G (IgG)—one of the major antibody classes found in colostrum. Each capsule provides 475 mg in an easy-to-swallow format.
Athletes and others under heavy physical stress sometimes see temporary increases in intestinal permeability. A 2024 meta-analysis of randomized trials (Hajihashemi and colleagues) pooled ten studies and found that bovine colostrum significantly reduced markers of intestinal permeability, including the urinary lactulose/rhamnose ratio and the lactulose/mannitol ratio, compared with control conditions.
Those trials used a range of doses and durations, often higher gram amounts than a single 475 mg capsule. Still, the meta-analysis supports why people interested in gut-barrier nutrition look to bovine colostrum as a researched food-derived option.
The same Frontiers review notes that advances in dairy processing have moved colostrum from a fresh, local food into stable supplement forms, and that clinical studies have examined its potential to support gastrointestinal and immune-related outcomes in adults. Immunoglobulins, growth factors such as IGF-1 and TGF forms, and other peptides are among the components researchers highlight.
Colostrum is also naturally dense in nutrients that support early life—proteins, fats, oligosaccharides, and micronutrients—which is part of why adult research keeps returning to it as more than a single isolated compound. CHF #40 keeps the formula simple: one high-IgG colostrum ingredient at 475 mg, taken daily before meals as the label directs, so you always know exactly what you are getting.
The CHF #40 label suggests one capsule daily one-half hour before meals. Taking colostrum away from a full meal is a common practical pattern for dairy bioactives, giving the proteins a clearer window in the digestive tract. Consistency matters more than perfection: pick a mealtime you can repeat, such as before breakfast or lunch, and stay with it.
Because this is a milk-derived ingredient, store the bottle as you would other capsules and keep it out of reach of children, as the label notes.
Research protocols have used a wide span of intakes—sometimes several grams per day in athletic or clinical settings, while many commercial products suggest hundreds of milligrams to about a gram daily. CHF #40’s 475 mg capsule sits in that everyday-supplement range. Your clinician can help you decide whether one capsule, or another schedule they recommend, fits your goals.
CHF #40 is a straightforward first-milking, high-IgG bovine colostrum capsule. It brings a researched dairy bioactive into a simple once-daily habit, timed before meals.
Who might enjoy it: adults seeking gut-barrier and immune-nutrition support from a food-derived ingredient, active people interested in the colostrum literature, and anyone who prefers a single-ingredient colostrum capsule with a clear label amount.
Colostrum is a milk product. Please check with your clinician first if you:
475 mg of first-milking, high-IgG bovine colostrum per capsule.
The label suggests one capsule daily one-half hour before meals.
No. It contains milk (colostrum).
Athletic and clinical trials often use gram-level intakes; commercial daily suggestions are frequently lower. Discuss the right approach with your clinician.
