Powerful Nutrients & Vitamins
Grass-Fed Bovine Colostrum
Contains 2.5 grams of cold-processed colostrum from grass-fed cows never given antibiotics, hormones, or GMOs. Colostrum is “Mother Nature’s perfect first food.” It’s the nutrient-rich fluid female mammals produce in the first few days after giving birth. It serves as the first source of nourishment for newborns and is packed with essential nutrients, antibodies, growth factors, and other bioactive compounds. Colostrum nourishes the gut microbiome, supports the mucosal barriers (e.g., gut, skin, lungs, etc.), protects against infections, and modulates the immune response.
Lactoferrin (Bioferrin®)
Contains 100 mg of lactoferrin (as Bioferrin®). Lactoferrin is a protein in the milk, tears, and saliva of mammals. It plays a vital role in defending against microbial invaders, promoting gut health, and enhancing the immune system's effectiveness. It also supports efficient iron metabolism—keeping it away from pathogens that require it and helping us to absorb it more efficiently. Lactoferrin is naturally present in small amounts (~3-5 mg per gram) in colostrum. We’ve included a much larger amount to amplify its benefits and provide better results.
Beta-Glucan (Wellmune®)
Contains 200 mg of beta-glucan (1,3/1,6 as Wellmune®). Beta-glucan is a naturally occurring polysaccharide in yeast, mushrooms, and other foods. It’s known as a “biological response modifier,” a class of compounds that regulate immune function. Beta-glucans help to “train” our innate immune cells, helping them to recognize and respond more quickly and efficiently to threats. Instead of boosting or suppressing the immune system, beta-glucans fine-tune it and restore balance.

Taking colostrum every day has really helped my gut to stabilize.
I just completed my 2nd month on the Bio-Avail Colostrum. I can tell a difference in my immune system. It is definitely stronger and improved. I am around my little grands who are constantly sick picking up school germs. I have remained completely healthy! Thank you Adapt for your true clean ingredients that benefit the body in powerful ways that other products DO NOT!! Keep up the good work you are doing with these products. Keep keeping them CLEAN & STRONG!!
This helps me maintain good gut health. I usually mix it with 8-10 oz of goat kefir, and put two adapt natural mutli pills mixed in; somtimes pomegranate extract also. ST
I’ve received colstrom today in my country and Olmost it’s cost me 150 USD including shipping, but once I open the package i really surprised and olmost 70% of pocket is empty space and it’s only 30% of product available inside ! However I didn’t try to effectiveness of this but I’m really disappointed about that !
It’s can last as fast as a week and 150 $ is expensive for that much of product
