Powerful Nutrients & Immune Support

GRASS-FED BOVINE COLOSTRUM (2.5 grams)

GRASS-FED BOVINE COLOSTRUM (2.5 grams)

Contains 2.5 grams of whole, unprocessed grass-fed colostrum from pasture-raised cows never given antibiotics, hormones, or GMOs. Our upgraded colostrum retains its natural golden color from carotenoids in grass-fed cows' diet – a sign of superior quality. 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 (as Bioferrin®) (100 mg)

LACTOFERRIN (as Bioferrin®) (100 mg)

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 (as Wellmune®) (250 mg)

BETA-GLUCAN (as Wellmune®) (250 mg)

Contains 250 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.

Why Choose Bio-Avail Colostrum+?

Bio-Avail Colostrum+ contains 2.5 grams of colostrum per serving—2.5x more than most competitors. This is critical because studies documenting colostrum's benefits typically use a dose of 2 grams or more. We source our colostrum from grass-fed, pasture-raised farms across the US, and it's free from pesticides, heavy metals, antibiotics, and artificial growth hormones. And it's cold-processed to keep the fragile immunoglobulins and other nutrients intact.

But we didn't stop there. We included two more compounds that support gut and immune health: lactoferrin and beta-glucan. Bio-Avail Colostrum+ is the first and only supplement that contains all three of these powerful ingredients. If you were to buy these products separately, you'd be spending well over $100—and taking more powder or pills.

Unlike skimmed or heavily processed colostrum that appears white and tasteless, our whole colostrum retains its natural golden color, beneficial fats, and complete nutrient profile – ensuring your body can utilize all nutrients as they work together naturally.

Good For You—And the Planet

You can't have healthy humans without a healthy planet. That's why Adapt Naturals is working toward zero plastic and landfill waste in our supply chain.

In the fall of 2023, we started transitioning our packaging to 100% compostable, stand-up pouches. They're made from cellulose (wood pulp) and are free of PLA, BPA, PFAS, phthalates, and other harmful chemicals. They're printed with non-toxic, compostable ink. The pouches are so clean and biodegradable that you can put them in your backyard or curbside compost bin!

Our sustainable packaging initiative will prevent over 120,000 plastic bottles from ending up in a landfill or the oceans. Thank you for being part of the solution and helping Adapt Naturals protect the beauty of our natural environment!

Your Questions Answered

Our whole, unprocessed colostrum has a richer, creamier texture that may require a bit more mixing than typical supplements. We recommend using a handheld frother or blender for the smoothest consistency. The natural dairy aroma and golden color are signs you're getting authentic, minimally processed colostrum.

You can mix Bio-Avail Colostrum+ into both foods and beverages! Recent research suggests that for generally healthy individuals, taking colostrum with food does not significantly impact its absorption or benefits. Feel free to stir it into yogurt, oatmeal, smoothies, or other foods and drinks.

However, we advise against mixing Bio-Avail Colostrum+ into hot beverages like coffee or tea, as high temperatures can degrade the delicate immunoglobulins and other beneficial proteins. Stick with room temperature or cold liquids and foods for optimal results.

If you have diabetes, metabolic issues, or simply find you get better results taking it on an empty stomach, mixing Bio-Avail Colostrum+ with 6-8 ounces of room-temperature water and drinking it 30 minutes before or 2 hours after a meal is still a great option.

We source our colostrum from grass-fed, pasture-raised farms across the US. It's free from pesticides, heavy metals, antibiotics, and hormones. And it's cold-processed to keep the fragile immunoglobulins and other nutrients intact.

While colostrum does contain a minimal amount of lactose, it is generally well-tolerated by people who are sensitive to lactose. We recommend speaking with your healthcare provider before supplementing with Colostrum+ if you are sensitive to lactose.

Yes, all dairy products (including colostrum) contain casein. We do not recommend taking Bio-Avail Colostrum+ if you have a casein sensitivity or allergy.

No. The pasture-based farms we source colostrum from understand the importance of colostrum to developing calves. The calves are fed 2–4 liters of colostrum shortly after birth. New mothers often produce more than 12 liters, so the farmers can harvest this excess colostrum without harming the calves.

Lactoferrin is naturally present in colostrum at 0.3-0.5%. This equals 3-5 mg per gram, or 7.5-12.5 mg per our 2.5 gram serving. However, Bio-Avail Colostrum+ also includes 100 mg of pure lactoferrin—yielding a total of 107.5 to 112.5 mg of lactoferrin per serving. This is far higher than other colostrum products that do not contain additional lactoferrin.

Yes, all Adapt Naturals products, including Bio-Avail Colostrum+, undergo rigorous third-party testing for purity and potency. Most importantly, we transparently share these results with our customers by posting Certificates of Analysis (CoAs) and test results on our website. This level of openness is almost unheard of in the supplement industry. It allows you to see exactly what's in the product you're putting into your body.
