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.

Don’t pass this up

I tried another brand for 2 months and switched to Adapt Naturals Colostrum. I’ve now been taking it for 2 months and there are noticeable changes . My bowel habits are like clockwork and my stomach bloat is gone. I saw my parents for the first time in 2 months. My father looked at me and said what have you done to your face your skin is so smooth and you have less wrinkles. I’ll take that for 58!!!
My hair was falling out by the handfuls in the shower but since I changed to Adapt Naturals Colostrum it has started growing and I have small sprouts of regrowth

Do not pass this miracle up!!

I am the only one in my circle who hasn’t gotten sick this season

My husband has been sick for the last month and a half, we went to a child’s party with 10+ kids, and I’ve been around other sick individuals in public. I have not gotten sick! I relate it to the colostrum.

Hi Meg,

That’s amazing to hear! Bio-Avail Colostrum+ is packed with immune-supporting compounds that help strengthen your body’s natural defenses, and it sounds like it’s been working for you. With everything going around, it’s great to have that extra layer of support—especially after being around so many germs!

We appreciate you sharing your experience and are so glad you’ve stayed healthy. Wishing you and your husband all the best!

Dissolve

Product does not dissolve well in liquid

Hi Joaquin,

Thanks for your feedback! Colostrum is naturally rich in proteins and immune-supporting compounds, which can make it a bit tricky to dissolve in liquid. Many of our customers find that using the Adapt Naturals Frother helps create a smooth, well-mixed consistency—whether you’re adding it to water, juice, or your favorite smoothie.

We appreciate you giving Bio-Avail Colostrum+ a try and hope this tip helps make it even easier to enjoy! Let us know if you have any other questions—we’re always happy to help.

Love this stuff!

I have Crohn's Disease so having extra support for my gut is crucial. I add a scoop to some orange juice every morning and I've noticed such a difference with my digestion and bloating. Highly recommend!!!

Hi Allee,

Thank you for sharing your experience! We know how important gut support is. It’s great to hear that Bio-Avail Colostrum+ has been a helpful addition to your routine.

Colostrum is a powerhouse for gut health, helping to strengthen the intestinal lining and support a balanced microbiome. And mixing it with orange juice? That’s a great way to make it part of your daily ritual!

We appreciate your recommendation and are so glad you’re feeling the difference. Wishing you continued gut health and well-being!
