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:

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.

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.

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.

get a shaker, its not dry scoopable. ( well it is but it take a long time to chew)

Molly Isbell
Not sure how I feel yet

I have used the custom product, half a scoop for a month now. My bowel movements are definitely regular, however I have a ton of bloating, gas, and tummy gurgling. Especially when I eat things like fruit. I’m wondering if I just keep on going and this will work itself out, or if it’s not the right product for me. I stopped using it the last few days because the bloating was bugging me so much. If I know that’s part of the process then I can push through, however I’m wondering if it’s the right thing. Would love some feedback

Jonathan Waltersdorf

Great colostrum product. I like that it includes lactoferrin and beta glucan. I would like to see bulk purchase options in the future, rather than the smaller sized subscription based.

Hi Jonathan, Thank you for reviewing our Colostrum+. You can always increase the quantity of product you would like to receive as well as adjusting the frequency. Example, you could choose to receive 3 or whatever amount you would like every 8 weeks or 12 weeks rather than every 4 weeks, whatever you would like. I hope this helps!
