What Is Grass-Fed Colostrum?

Grass-Fed Colostrum bottles

Grass-Fed Colostrum is a capsule-form supplement with one ingredient: bovine colostrum sourced from New Zealand cows.

Colostrum is the milky substance produced by female mammals right after they give birth.

It’s the first “drink” that baby mammals have after they are born, giving them a potent dose of vitamins and minerals to boost their immune systems.

Colostrum arms the baby mammal with everything they need to survive their dangerous first phases of life.

People choose to take Grass-Fed Colostrum for immune system boosting, exercise stamina, muscle building, anti-aging, and improved gut health.

About Ancestral Supplements

They only make small batches (for quality control reasons) so their products aren’t always readily available.

Grass-Fed Colostrum Ingredients

Grass-Fed Colostrum ingredients

New Zealand Grass-Fed Colostrum (Bovine) 1500 – 3000 mg per serving (500 mg per capsule).

Grass-Fed Colostrum contains a wide range of nutrients such as:

  • Lactoferrin: a protein with antibacterial and antioxidant properties that also helps to transport iron (hence the “Ferrin” in the name) around the body. Lactoferrin has been used to treat and improve skin issues, ulcers, diarrhea, and improving immune response 2.
  • Antibodies/immunoglobulin: IgA, IgD, IgE, IgG, and IgM are antibodies that recognize and destroy viruses and bacteria to protect you against illness and infection 3.
  • Growth factors: EGF, TGF, PDF, and IGF I and II are growth factors that help the body to grow and repair skin, muscle, tissue, bones, and cartilage. They also help to repair DNA, making them excellent for anti-aging.
  • Glycoproteins: these proteins help to keep the skin sturdy and healthy, protect important cells from stomach acids, and help white blood cells (immune cells) to roam the body looking for pathogens to destroy 4.
  • Lysozyme: an antibacterial and antiviral substance that protects the body from illness 5.
  • Amino acids: for building and growing muscles.

Grass-Fed Colostrum Side Effects

In general, bovine colostrum supplements are safe to take and are not associated with side-effects.

It does depend on the cows that the colostrum is sourced from and whether they are raised with hormones or pesticides.

Because Grass-Fed Colostrum does not contain any hormones, pesticides, or fillers, the risk of side-effects is even lower.

There are very few reviews describing side-effects when taking Grass-Fed Colostrum.

Someone mentioned that they developed pinworms since taking it, however, we couldn’t find sufficient evidence to support the likelihood of this.

Another person found that they experienced a sore stomach:

“Too early to tell. I did get an upset stomach after taking it a few times. I reduced my doses to see if it was too strong.”

Overall, we’re confident that Grass-Fed Colostrum doesn’t pose a high risk of side-effects.

However, it’s always best to check with your doctor first, so they can assess the safety of supplements against your medical history, medications, and health concerns.

Is Grass-Fed Colostrum FDA-Approved?

No, because the FDA doesn’t approve dietary supplements.

However, Ancestral Supplements sources their ingredients from GMO, pesticide, and hormone-free farms.

Plus, they also have their products 3rd-party tested for purity and safety.

Is Grass-Fed Colostrum A Scam?

No, we’re confident that Grass-Fed Colostrum (and Ancestral Supplements) is not a scam.

We haven’t uncovered any dirt on the company, and the product reviews across the brand are extremely high (we checked with a false review tracker and there’s no evidence of fake reviews).

What’s more, Ancestral Supplements is known for offering excellent customer service.

For example:

“Customer service is outstanding Brian the owner has answered my questions and has gone beyond the call of duty to help me with my healing process.”

“I can’t say enough good things about this colostrum and about the customer service.”

Grass-Fed Colostrum Reviews & Complaints

Grass-Fed Colostrum pills

Let’s start with the negative reviews, of which there are very, very few.

This person simply found that Grass-Fed Colostrum didn’t garner any results:

“Well I’ve taken just about the full bottle, thought I’d wait to see if any change or results would happen after a while. Sad to say I didn’t see any results, nor anything negative”.

Now for the positive.

There are many long and descriptive reviews raving about the positive results experienced since taking Grass-Fed Colostrum.

Many people found that their workouts and muscle-building improved, and others found that they had improved digestion, strong immunity, clearer skin, and more energy.

“I have been able to increase weight and output at the gym and I don’t have the same aches and pains after a long run. It sounds cliche, but I just feel really good over all…energy, mood, body, mind. The pills are easy to swallow and easy on the stomach”.

“I added in the Colostrum to my daily routine a few weeks ago. I had heard about all the great effects it can have and I wasn’t sure how many of them I’d actually get, but it was even better than I imagined! I’m recovering faster from workouts, my digestion is a lot better, and my skin is even more cleared up”.
