Powerful Nutrients & Vitamins

Grass-Fed Bovine Colostrum

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®)

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®)

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.

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 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.

FIGHT PREMATURE AGING

Want to turn back the clock and maintain your youthful glow? Bio-Avail Colostrum+ harnesses the anti-aging benefits of colostrum, lactoferrin, and beta-glucans to help you fight premature aging from the inside out.

The essential nutrients, antibodies, and growth factors in Bio-Avail Colostrum+ slow biological aging by nourishing the microbiome, sealing the gut lining, supporting the immune system, and promoting overall vitality. Lactoferrin defends against threats and promotes a healthy gut environment, while beta-glucans fine-tune your immune response to keep your body's defenses strong and resilient.

The result? A more youthful appearance, increased energy, and unstoppable vitality. Say goodbye to premature wrinkles, dull skin, and brittle hair and nails. With Bio-Avail Colostrum+, you can unlock your body's innate ability to heal, regenerate, and thrive.

Formulated to Rebuild Gut and Immune Health

From processed food to environmental toxins to chronic stress, the modern world makes health hard. Bio-Avail Colostrum+ was formulated to rebuild your gut health, fortify and strengthen your immune defenses, and restore immune balance. Supporting the “gut-immune axis” is one of the most important things we can do to improve our overall health and extend our lifespan. Bio-Avail Colostrum+ promotes enhanced vitality, a more youthful and radiant appearance, and greater protection against the challenges of daily life.

Harness Years of In-Clinic Experience and Ancestral Wisdom

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

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. Click here to view the most recent CoA and test results.

Can’t go without it!

This colostrum has made a huge difference in how I feel and look! My hair, skin and nails have all greatly benefited from this! My hair had started thinning a little on top and now it’s back to being full and shiny. It has kept me healthy while being around people that are sick.

I’m sure it’s good…but I can’t get it down

I’ve tried this in water, And taking it dry, and I cannot get it down. I’m nervous to try it any other way as I’m sure it will still be difficult to eat it in yogurt or a smoothie. I usually do OK with supplements, so I’m bummed that I’m not doing well with this one

I don't go a day without this

Bio-Avail Colostrum+ has become my favorite supplement! Since taking it, my hair has been healthier, my gut has felt better and feel like my immune system has been at its best.
