Colostrum 6-Review

When it comes to supplements—especially those meant to bolster your immune system—we tend to envision capsules filled with the latest in natural immune-boosting herbs, amino acids, vitamins, and minerals. 

But is “building a better mousetrap” really the way to go when in fact, the original immune booster is none other than mother’s milk—or more specifically, colostrum? 

Immune Tree says “no,” and are here to prove to you that colostrum is indeed the way to rev up your immune system, look and feel younger, and much more. So, is this supplement worth taking? Let’s find out with this Colostrum6 review.

Immune Tree Colostrum6 Supplements

About Colostrum6

For the first 6-hours (or so) after birth, bovine mothers produce nature’s “1st whole food,” which is colostrum. It contains over 95-immune factors and 87-growth factors, all of which work to promote a sound body, efficient metabolism, and a high-functioning immune system. 

Immune Tree harvests theirs from organically fed cows, but only after Mamma’s newborn calf has had their share, since that’s who deserves it the most! Once it’s been harvested, it goes through a low-temperature spray-drying process along with rigorous 3rd party testing to ensure it meets all 6-hour standards of harvest and quality.

Colostrum6 Benefits

There are many benefits to consuming colostrum. We will take a closer look at a few main benefits below.


As you age, your production of growth hormone, AKA HGH, declines. Since HGH is necessary for maintaining skin elasticity and muscle mass, this means sagging, wrinkled skin and poor muscle tone along with all the other aches, pains, and slowing associated with old age. 

But colostrum contains Insulin-like Growth Factor (IGF-l and IGF-2) and Transforming Growth Factor (TGF-alpha and TGF-beta), which help increase your growth hormones to pre-pubescent levels. This helps wounds heal faster, helps increase lean muscle mass, and keeps your skin taut, smooth, and elastic while stimulating the growth and repair of your RNA and DNA.

Broad Spectrum Probiotics In Their “Whole Food” Form

Colostrum has a higher nutritional density than “regular” cow’s milk, which means more protein, immunoglobulins, vitamins, and minerals for you, the consumer. This also includes lactoferrin, growth factors, and antibodies, all of which are types of protein compounds that affect your immune health for the better when you consume colostrum. 

Supports Healthy Digestion

Colostrum doesn’t just support the production of new muscle and skin cells; it also stimulates cell rejuvenation in your digestive tract—something which helps it stay “young” and productive. 

It also helps promote the growth of certain gut bacteria that are essential to your immune system, which includes Bifidobacterium longum—a type of bacteria that are known to improve the gut barrier integrity and reduce inflammation of the digestive tract. 

Altogether, this means healthy digestion for you, better nutritional uptake, and the improved immune system that goes along with improved gut health.

Nutritionally Dense

Sure, you can take pills by the truckload, though few will do you as much good as colostrum when it comes to keeping your health on track. That’s because colostrum isn’t just compounds extracted and isolated, but is instead, whole food that’s about as nutritionally dense as it gets.

This includes not only high-quality proteins, fats, and carbs, but enzymes, enzyme inhibitors, nucleotides and nucleosides, calcium, phosphorus, magnesium, and many other compounds. Though many of these compounds are also found in regular cow’s milk, the concentrations aren’t as high as what mamma cow gives her precious little ones.

Colostrum6 Ingredients

Though there is technically only 1-ingredient in Immune Tree’s Colostrum6, there are many ingredients within. These include oil-soluble vitamins A, E, D, & K, as well as water-soluble vitamins, including vitamin C (in high concentrations since calves don’t begin producing it in their livers until around 3-weeks of age), thiamin, riboflavin, niacin, biotin, pantothenic acid, folate, pyridoxine, and cobalamin (B-complex vitamins, in other words). 

Other compounds found in Colostrum6 include sugars such as lactose and glucose, fructose, glucosamine, galactosamine, N-acetylneuraminic acid, and oligosaccharides, as well as proteins such as casein, immunoglobulins, beta-lactoglobulin (β-lg), and alpha-lactalbumin (α-la), all of which occur in higher levels than in regular milk. This not only helps the youngster get a healthy start to life; it also provides you with compounds that keep you looking and feeling healthy and young. 

But what are arguably the most important ingredient in Colostrum6 are the growth factors, including epidermal growth factor (EGF), betacellulin (BTC), insulin-like growth factor I (IGF-I), IGF-II, transforming growth factor-β1 (TGF-β1), TGF-β2, fibroblast growth factor 1 and 2 (FGF1 and FGF2), and platelet-derived growth factor (PDGF). These are the compounds that keep you and your immune system healthy, active, and strong. This includes cell rejuvenation so that your skin stays elastic, you heal from wounds and illness quickly, and your muscles remain dense, strong, and lean. 

Immune Tree Colostrum6 Supplement Facts

Does Colostrum6 Work?

When mammals are born, there are certain compounds in their mother’s milk that enables them to get the best, most healthy start to life they can. This includes starting their immune system off right, which needs to be done in the first hours of the little tyke’s life. For cows, this means nutrient-dense colostrum production for the first 6-hours of the youngster’s life. 

But since you’re likely older than 6-hours (and if not, let’s get you to the Ripley’s Museum as the youngest ever to read a supplement review!), your levels of growth hormones have declined along with the nutrient density of your mom’s milk (which we assume you’ve moved on from by now). This means looser, more wrinkled skin, saggy muscles, increased body fat, and slower wound healing. 

But colostrum, with its influx of youthful growth hormones and nutritional density will work to help reverse all of this. This includes being an outstanding pre-or-post-workout supplement, since it contains much of the proteins, minerals, and sugars you need for recovery and muscle growth. 

So yes, as long as you aren’t allergic to milk or colostrum, Immunity Tree’s product will help restore your growth hormones to youthful levels while acting as one of nature’s perfect superfoods—which it is!

Who Is Colostrum6 Best For?

While there are no known drug interactions, Colostrum6 will boost the uptake of compounds due to its positive effects on digestive health. This may influence your medicine dose and may require re-evaluation by your doctor. 

And, while colostrum is literally made by nursing mothers, you should nonetheless consult with your doctor first if you are pregnant or breastfeeding. 

Though Colostrum6 doesn’t contain nearly as much lactose as regular milk, it does contain trace amounts. This may require some consumers to use a lactose digestive aid or avoid Colostrum6 entirely. 

It can also be used by all ages, though it’s best to consult with your doctor or pediatrician before giving it to young kids, and it’s even great for pets, since Fido and Kitty are also family members who need to stay healthy. 

Claims vs. Reality

With plenty of proof through the ages of colostrum working for newborns and adults alike, you can be assured that Immune Tree is selling you something that works. It contains many beneficial compounds that adults no longer produce, which allow your body to rebuild and grow like it did when you were young. This means fast wound healing, rapid muscle growth, and an immune system that can stop a tank—or at least most pathogens. 

That, and you’ll look younger and feel great in the gym as you add lean, dense muscle like you’re in high school again. 

Is Colostrum6 Safe?

As mentioned above, Colostrum6 does contain trace amounts of lactose, which many are allergic to. While levels aren’t nearly as high as in regular milk, those who are highly sensitive to lactose may need to avoid Colostrum6 or use it along with a digestive aid. 

Some may also experience flu-like symptoms, acne, and active bowels, which is actually good since that means colostrum is working to detox you! This will only last a short period, so drink plenty of water, eat a clean diet that excludes alcohol, sugar, and nicotine, and get ready to feel great once you’re done feeling crappy.

Where To Buy Colostrum6

Immune Tree offers its Colostrum6 in lozenges, powder, or capsules, and in a variety of sizes at various values. This includes 90-count capsules for $25, 180-count capsules for $43.75, 6.5oz (120 serving) powder for $65, a full kilo (661 servings) for $202.50, and pineapple or strawberry moo flavored lozenges, which sell for $41.25 for 65-days’ worth. 

Though there aren’t any apparent discounts other than a higher value for higher volume containers, they do offer free shipping on orders over $99. Overall, we’re quite pleased with the value of this product, especially considering it’s organic and nutritionally-dense with compounds you’d be hard-pressed to find elsewhere—at least not safely. No, HGH injections simply AREN’T a good idea, though you can safely elevate your levels of it with this product.

Immune-Tree Website

Along with Immune Tree’s website, the product is widely available on Amazon and other online retailers, as well as traditional brick-and-mortar retailers who sell immune-boosting health supplements, including Walmart. Look for it at your favorite independent retailers, though, since Walmart and Amazon already make plenty enough, and it’s the small guys who need your business.
