Introducing the first beauty-boosting colostrum, lactoferrin, and beta-glucan blend—your all-in-one natural beauty solution!

Bio-Avail Colostrum+ is the first and only product on the market that combines cold-processed colostrum from grass-fed cows with two other "beauty and immune health superstars": lactoferrin and beta-glucan.

Unlike other colostrum supplements, which only provide colostrum, Bio-Avail Colostrum+ includes 100 mg of lactoferrin and 200 mg of beta-glucan, 2 other powerful nutrients that support skin, hair, nail, and immune health.

Bio-Avail Colostrum+ is the first and only supplement to combine all 3 of these ingredients in a single product.

What makes Bio-Avail Colostrum+ stand out?

  • More than double the colostrum

    Bio-Avail Colostrum+ contains 2.5 grams of colostrum vs. 1 gram found in many products. We source our colostrum from 100% pasture-raised cows never given hormones, antibiotics, or GMOs.

  • Contains 200 mg of beta-glucan

    Bio-Avail Colostrum+ has 200 mg of beta-glucan (1,3/1,6) as Wellmune®. Beta-glucans help hydrate skin from within, reducing the appearance of fine lines and wrinkles.

  • Contains 100 mg of lactoferrin

    Bio-Avail Colostrum+ includes 100 mg of lactoferrin (as Bioferrin®). Lactoferrin helps defend against microbial invaders, promotes gut health, and enhances the immune system’s effectiveness.

Formulated to Enhance Natural Beauty

From environmental toxins to nutrient-poor diets to chronic stress, the modern world takes a toll on your natural beauty. Bio-Avail Colostrum+ was formulated to nourish your skin, hair, and nails from within. By supporting the "gut-beauty axis," we're addressing one of the most overlooked aspects of radiant beauty. Bio-Avail Colostrum+ promotes a more youthful and radiant appearance, enhances hair and nail strength, and provides greater protection against the visible signs of aging.

Here are some benefits you can expect from this one-of-a-kind product:

✓ Enhances skin radiance: Boost collagen production for firmer, more youthful-looking skin.

✓ Improves hair vitality: Nourish hair follicles for thicker, shinier locks.

✓ Strengthens nails: Provide essential nutrients for stronger, faster-growing nails.

✓ Supports gut-beauty connection: Nourish your microbiome for clearer, healthier-looking skin.

Bio-Avail Colostrum+ contains:

GRASS-FED BOVINE COLOSTRUM
2.5 grams of cold-processed colostrum from grass-fed cows never given antibiotics, hormones, or genetically modified organisms (GMOs). Delivers 2.5 times more colostrum per serving than most brands. Rich in growth factors that stimulate collagen production, promoting firmer, more youthful-looking skin.

LACTOFERRIN (BIOFERRIN®)
100 mg of lactoferrin (as Bioferrin®). Lactoferrin helps defend against microbial invaders, promotes gut health, and enhances the immune system’s effectiveness. Supports efficient iron metabolism, crucial for healthy hair growth and strong nails.

BETA-GLUCAN (WELLMUNE®)
200 mg of beta-glucan (1,3/1,6) as Wellmune®. Beta-glucans are “biological response modifiers” that strengthen and balance the immune system while reducing hypersensitivity. Helps hydrate skin from within, reducing the appearance of fine lines and wrinkles.

Bio-Avail Colostrum+ gives you 3 powerful beauty-enhancing nutrients in a single product—at a significantly lower price than you'd pay for them separately.

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 lactose intolerant. We suggest that people who are lactose intolerant speak with their healthcare provider before supplementing with colostrum.

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.

Bio-Avail Colostrum Works!

I started taking Bio-Avail Colostrum to help support my gut. I've done a cleanse and had been taking Biome Protect for several months with good results of bowel movements, but my stomach and gut were still irritable. If I ate the wrong thing or just daily for no reason, I would get cramping or bloating. Since I started taking this colostrum, my symptoms have almost completely resolved. The only time they recur is if I miss taking it for several days. It has also helped with my skin, providing a smoother, more moist and youthful appearance! I'm very happy with this colostrum and recommend it frequently.

Hi Tara,
Thank you so much for sharing your detailed experience — it means a lot to us! It’s incredible to hear how much Bio-Avail Colostrum+ has helped calm your gut symptoms and even supported your skin health. We’re happy to hear that you notice the difference when you miss it, consistency truly can make all the difference with foundational gut support. We’re honored to be part of your wellness routine, and we appreciate you recommending it to others!

High quality good product

Ive tried 2 different colostrum brands and i love adapt naturals especially that it has lactoferrin. I have noticed stronger nails and less bloating since taking this.

Hi Cindh,

Thank you so much for your kind words! We’re thrilled you’re loving Bio-Avail Colostrum+ and noticing those tangible benefits. Including lactoferrin was intentional to support immune and gut health, and we’re so glad it’s also helping with bloating and nail strength as well. We appreciate your support!

Catherine Poulin

The first month taking Colostrum I was very happy with the bowel movements. I am on my second Colostrum and do not see the same results so I am left to assume I have cleaned out my system.

Hi Catherine,

Thank you for sharing your experience — we really appreciate it. It’s actually quite common for colostrum to support more noticeable digestive shifts early on, especially as it helps strengthen the gut lining and rebalance the microbiome. Over time, many people find that regularity stabilizes at a new, healthier baseline.

That said, if you feel like you’re not seeing the ongoing support you'd hoped for, please remember you're covered by our 60-day money-back guarantee — and we're always here to help troubleshoot or answer any questions that may come up. Take care!

Great product!

I was using the other more popular brand and was having so many issues with fulfillment and switched to Adapt. It has been great!!

Hi Sarah,

We’re so glad you made the switch and that it’s been a smooth experience! Bio-Avail Colostrum+ uses pure, grass-fed colostrum plus lactoferrin and beta-glucan for gut and immune support. We appreciate your trust and are happy to have you with us!

Immune booster

Both my wife and I work in health care and in 18 months I have been taking this colostrum I havent been sick once. Even living in close quarters with my wife when she has brought home bugs I haven’t caught any of them.

Hi Sunny,

Wow — thank you for this sondeful feedback! Bio-Avail Colostrum+ supports mucosal immunity (our first line of defense) through immunoglobulins, lactoferrin, and growth factors, which may help explain your resilience even in close contact settings. We’re honored to support both you and your wife as healthcare workers — thank you for all you do!
