Wake Up Without Bloating, Support Your Immune Defenses, and Discover Why Your Hair Stylist Asked What You're Taking

Your gut houses 70% of your immune system and directly influences your skin, hair, energy, and how often you get sick.

When your gut barrier breaks down, everything suffers. Chronic bloating. Frequent sick days. Seasonal sensitivities. Accelerated aging you see in the mirror.

Colostrum rebuilds this foundation. It's nature's first food for all mammals, packed with antibodies, growth factors, and compounds that seal the gut barrier and train the immune system.

Here are five reasons why Bio-Avail Colostrum+ transforms your gut, immunity, and appearance:

Reason #1: Your Gut Finally Works the Way It Should (No More Bloating, Fear, or Bathroom Emergencies)

Wake up without that puffy, bloated feeling. Eat meals without wondering which foods will trigger you. Make plans without mapping bathrooms first.


Your bowel movements normalize. The urgency disappears. You start eating foods you'd eliminated years ago, and nothing happens. No reaction. Normal digestion doing what it's supposed to do.


Colostrum seals your gut barrier at the cellular level, repairing the tight junctions that let toxins and undigested food leak into your bloodstream. When your gut barrier is intact, your immune system stops constantly reacting to things that shouldn't be in your blood. The growth factors rebuild damaged tissue while prebiotics feed beneficial bacteria, crowding out harmful species. This means you stop living in constant discomfort and start living normally again.


Week 1-2, you're less bloated after meals. By week 4-8, you realize you haven't thought about your gut in days. You're eating freely and making plans without bathroom anxiety.

Real Customer Review:
"After trying yogurt, probiotics, kefir, kombucha, all the things, I thought I'd never have a normal healthy gut again. I was bogged down with bloating and diarrhea for 2 years. After at least a month, my guts were changing and I was less gassy and feeling so much better! I'm happy to have finally found my 'cure.'" — Shelley Holmquist

Reason #2: Get Sick Less Often (Even When Everyone Around You Is Down)

That bug making its way through your office? You might not catch it. Your kids bring home germs from school, your coworkers come in sick. You often stay healthy.


When you do get sick, you may recover faster. What used to keep you down for a week may pass in two to three days. Your body fights back instead of surrendering. And those seasonal immune challenges? They may start fading or improve noticeably.


Colostrum delivers antibodies (IgG and IgA) that support your body's mucosal defenses. Bio-Avail Colostrum+ amplifies this with two additional compounds:


Lactoferrin (100mg, 30x more than colostrum contains) binds iron to support immune function and helps maintain your body's natural defenses.


Beta-glucan (200mg Wellmune®) supports your innate immune cells, helping them function more efficiently.


Colostrum provides antibody support. Lactoferrin binds iron and supports immune defense. Beta-glucan supports immune cell function. This is why many customers report getting sick less often, even during seasonal challenges.

Real Customer Review:
"I am just finishing my first 30 days with this product. The one thing I did notice is that my immune system is 'immune' to the people around me that have been sick in the past month." — Stephanie Rowe

Reason #3: Look in the Mirror and Wonder What Changed (Hair, Skin, Nails That Make People Ask Questions)

You bought it for your gut. But three weeks in, you notice your hair feels different. Thicker. Fuller.


By week eight, you're seeing regrowth where your hair had been thinning. Your hairdresser comments: "What are you taking? You have so much new growth."


Your skin starts glowing (not from highlighter, but radiance from within). That crepe-like texture smooths out. Fine lines soften. Your nails grow stronger without peeling or breaking.


Then the comments start. Family says your skin looks smooth. Friends ask if you've had work done.


When colostrum supports your gut barrier health, your skin may benefit through the gut-skin axis. Growth factors in colostrum (EGF and IGF-1) support your body's collagen production (what gives your skin elasticity and your hair strength). Lactoferrin supports healthy cellular function in your skin cells and hair follicles.


This is internal healing showing externally. Your body rebuilding from the cellular level.


Timeline: Subtle changes by week 2-3. Obvious transformation by week 8-12.

Real Customer Review:
"I initially bought this product to address gut issues. I can't say those issues have been remedied, but my skin has improved (less crepe-like and more vibrant). I am a menopausal woman. I have recommended this to many friends!! NOTE: I could see the changes to my skin in less than three weeks." — Stephanie Suarez

Reason #4: One Product Does What Three Used to (And Works Better Together)

Most colostrum supplements give you colostrum. Period. One ingredient, one pathway.


Bio-Avail Colostrum+ combines three compounds that amplify each other's effects. No more buying separate products. No more juggling multiple supplement routines. One scoop, one time per day, complete gut-immune support.


Think of your gut-immune system like a fortress. Colostrum rebuilds the walls. Lactoferrin guards the gates. Beta-glucan trains the soldiers.


2.5 g Grass-Fed Colostrum: Seals gut barrier, provides antibodies, feeds beneficial bacteria


100 mg Bioferrin® Lactoferrin: Binds iron to support immune function (30x more than colostrum naturally contains)


250 mg Wellmune® Beta-Glucan: Supports immune cell function, studied in 25+ clinical trials


Bought separately: $115-160/month for three bottles. Together in Bio-Avail Colostrum+: $50-60/month at clinical doses.

Real Customer Review:
"I'm 40 years old and am so thankful to have FINALLY found supplements (Adapt Naturals) that actually feel like they're supporting my health in a real way!" — Stephanie Larsen

Reason #5: This Is the Colostrum That Delivers What the Research Promises

You've tried colostrum before. It didn't work or worked minimally. After a month or two, you stopped because you weren't seeing results worth the money.


Most colostrum products fail before you open the bottle. Bio-Avail Colostrum+ is different:


The dose: Studies showing benefits used 2+ grams daily. Most products contain 500mg-1g. Bio-Avail Colostrum+ delivers 2.5 grams.


The form: Most colostrum products use skim colostrum (with the fat removed). Bio-Avail Colostrum+ uses whole colostrum with all the natural fats intact. This matters because those fats contain fat-soluble nutrients, support the absorption of fat-soluble vitamins, and help protect the fragile immunoglobulins during digestion. Whole colostrum is colostrum in its complete, natural form—the way nature designed it.


The source: Grass-fed, pasture-raised cows from US farms. Never given hormones or GMOs. Higher nutrient density, zero contamination.


The transparency: Many brands hide IgG content or claim vague minimums. Bio-Avail Colostrum+ is third-party tested and guaranteed 25% IgG. We test every batch for heavy metals (undetectable), pesticides (none), antibiotics (none), and potency (verified). Results available.


This is why customers who tried other colostrum products with no results experience transformation with Bio-Avail Colostrum+.

Real Customer Review:
"I have taken colostrum many times over the years for my gut health, and I've never noticed a benefit until taking this one from Adapt Naturals." — Deena Thompson

WHY I CREATED THIS

Why I Created Bio-Avail Colostrum+


For 15 years, I worked with patients whose gut issues didn't respond to probiotics, elimination diets, or standard supplements. They needed something more powerful to support their gut barrier and help modulate their immune response.


The patients who transformed were the ones taking colostrum, lactoferrin, and beta-glucan together. The combination worked when individual products didn't. But that meant buying three separate products from different companies, spending $100-150 monthly, and hoping they were getting quality ingredients at effective doses.


Patient after patient asked: "Isn't there one product that has all three?"


There wasn't. So I created it.


Bio-Avail Colostrum+ delivers what I saw work in clinical practice over more than a decade: all three compounds, at the doses that produced results, in forms your body absorbs, from sources you can trust.


Not to educate people about colostrum, but to give them the version that works.

Most people with lactose intolerance can take colostrum without issues. Colostrum contains very low levels of lactose compared to regular milk. However, if you have a severe dairy allergy (not just lactose intolerance), consult your healthcare provider before starting.

Most colostrum products fail because of dose (500mg-1g vs. our 2.5g clinical dose), form (skim vs. our whole colostrum with natural fats intact), and missing synergistic compounds. Bio-Avail Colostrum+ also includes Bioferrin® Lactoferrin (100mg) and Wellmune® Beta-Glucan (250mg) that amplify colostrum's effects. Plus, we guarantee 25% IgG content—third-party tested and verified.
