There is nothing worse than a pet with an upset stomach. Not only do they feel terrible, but you have to deal with the consequences. I’m talking about stains on the carpet, sleep interruptions, and oh wow, what’s that smell?!

If this is something you have to deal with frequently, you know all too well what I’m talking about. You probably also know that probiotics and other recommended digestive solutions aren’t enough. That’s where Sovereign Laboratories’ Super Pet Nutrition Colostrum-LD Powder comes in.

This product has been a major game changer for my rescue kitty. After spending the first few months of his life on antibiotics, my cat, Makoa, had the worst gas and frequent diarrhea and nothing we did would help. But after just a couple of weeks on Colostrum-LD, he is a whole new feline.

Keep reading to find out why I recommend this product so highly and what it can do for your pet in my full Super Pet Nutrition Colostrum-LD Powder review, below.


About Sovereign Laboratories

Super Pet Nutrition Colostrum-LD Powder

Sovereign Laboratories was founded by Douglas Wyatt over 30 years ago. He first turned to colostrum as a potential health supplement to help his ailing wife. At the time, there were no commercial colostrum supplements available.

To fill the need, Wyatt developed his own process for extracting and dehydrating bovine colostrum using liposomal encapsulation. From there, Colostrum-LD was born.

Today, Sovereign Laboratories has a long line of health supplements focused on aging, digestion, and immunity. One of their lines, Super Pet Nutrition, is dedicated to bringing the health benefits of colostrum to our furry family members.

What Pet Products Does Sovereign Laboratories Offer?

Sovereign Laboratories’ Super Pet Nutrition line contains one product, which is available in three sizes.

Their pet Colostrum-LD powder contains the same short list of powerful ingredients as their flagship unflavored colostrum product for humans.

This highly effective supplement is made to support:
  • A healthy immune system
  • Intestinal health
  • Healthy skin and coat
  • A healthy inflammatory response

Super Pet Nutrition Colostrum-LD contains no soy, corn, grain, flavors, or filler ingredients.

It is available in three sizes: 50 grams, 6 ounces, and 12 ounces.

Which Type of Pet is Colostrum-LD Best Suited For?

Colostrum is a substance produced by all mammals during the first nursing sessions. This special milk helps newborns develop a strong immune system and supports normal, healthy growth and development.

While colostrum is only available to mammals during those first few days of life, the substance remains beneficial throughout development and into old age.

Colostrum-LD can benefit any mammalian pet, including cats, dogs, hamsters, mice, guinea pigs, and rabbits. It is an especially good option for pets who struggle with frequent digestive upset, a weakened immune system, autoimmune disorders, or chronic stress.

Here is an overview of Super Pet Nutrition Colostrum-LD. We’ll look at the ingredients in this popular product, how it’s processed for maximum absorption, how to dose it, and what to expect after giving it to your pet.


Colostrum-LD for pets contains just two ingredients, a testament to its purity and potency.

The active ingredient is bovine colostrum. This natural product is collected from Grade A dairy cows during the first milking after they give birth. While this product is not labeled as organic, the cows it comes from are not treated with growth hormones or antibiotics.

Bovine colostrum is full of naturally occurring compounds that help support health, including:

  • Immunoglobulins – Antibodies that aid the immune system in recognizing and destroying common bacteria and viruses.
  • Growth Factors – Proteins that support cell growth, differentiation, and survival while enhancing tissue repair and reducing inflammation.
  • Lactoferrin – A protein that helps bind iron to improve absorption. Iron is an important mineral for newborns and those recovering from illness and digestive inflammation.
  • Amino Acids – These compounds are the building blocks of proteins and life. Colostrum contains all essential amino acids and is especially high in glutamine and glutamate.

The only other ingredient in this product is sunflower lecithin, which acts as an emulsifier and helps improve absorption.

The “LD” on the end of Colostrum-LD stands for “liposomal delivery.” What this means is that this colostrum product is specially processed to coat it in bio-identical liposomal lipids extracted from cow’s milk and sunflower oil.

These lipids help protect the valuable compounds in colostrum through dehydration and digestion. This ensures that more of the colostrum is intact and ready to be absorbed by the time it gets to your pet’s gut.


Super Pet Nutrition Colostrum-LD is easy to give pets of all types. The package recommends giving the product twice a day, with a dose based on weight:

  • 1 to 10 pounds – ½ teaspoon
  • 10 to 40 pounds – 1 teaspoon
  • 50 to 100 pounds – 2 teaspoons

Colostrum has a natural cheesy flavor and scent. Most dogs, cats, and rodents are naturally attracted to this scent and will happily eat Colostrum-LD if it is added to their normal food. You can also add the powder to their water.

What to Expect

My cat, Makoa, has a long list of digestive issues that I was hoping this product could help with. I first noticed an improvement in his symptoms within a few days of starting the product. Within three weeks all his digestive issues had been resolved and some of his other symptoms were noticeably improved.

I speak more about this in the “Experience” section, below.

Sovereign Laboratories says the full effect of the product can be expected after feeding it twice daily for about a month.

In Summary

  • Easy to administer
  • Only two ingredients
  • Corn, soy, and grain-free
  • Naturally palatable to pets
  • Easily absorbed
  • From Grade A, pasture-raised cows
  • Takes time to dissolve in water
  • Bags are hard to reseal
  • Not organic


Key Features

Liposomal Lipid-Coated

What sets Sovereign Laboratories’ colostrum products apart from the competition is their patented liposomal lipid coating processing technique. This process coats the fragile colostrum compounds in liposomal lipids to help protect them through dehydration and digestion.

What this means for your pet is that more of the good in the colostrum is available to be absorbed into their bodies. This is why Colostrum-LD is so effective and why it’s the most popular bovine colostrum product in the world.

Simple Ingredients

Each bag of Super Pet Nutrition Colostrum-LD Powder contains only pure bovine colostrum and a touch of sunflower lecithin. This means you aren’t paying for fillers or other low-quality ingredients. It also means each scoop is packed with health-supporting compounds.

Easy to Use

Colostrum-LD Powder doesn’t have any added flavors because it doesn’t need it. The product has a natural powdered-cheese scent and flavor that most pets are attracted to. When mixed with water or food, even picky pets seem to have no problem gobbling this supplement up.


Is Colostrum-LD Powder a Good Value?

Depending on which sized bag of Colostrum-LD you opt for, you’ll pay about $5 to $6 per ounce. You could pay quite a bit more for competitor pet colostrum products.

These other products lack the liposomal lipid coating that makes Colostrum-LD so effective. So, with that in mind, I’d say this product is a very good value. It isn’t the cheapest pet supplement in the world, but it is one of the most affordable options in this category and more than worth the price.

Can pets be allergic to colostrum?

Unlike humans, most mammals struggle to digest lactose after they are weaned. However, colostrum naturally contains only low levels of lactose and is well tolerated by most pets. Of course, if your pet has a negative reaction to the product, you should stop using it.

How long will it take my Colostrum-LD to arrive?

Sovereign Laboratories offers free ground domestic shipping on all orders. You can expect your package to arrive within 4 to 5 days if you live in the continental US.

What is the refund policy for Colostrum-LD Powder?

Sovereign Laboratories offers a 45-day refund on all their products if you are dissatisfied with the product or the results.


Our Experience With Super Pet Nutrition Colostrum-LD Powder

My cat, Makoa, has had quite a life already, and he is only seven months old. I found him walking blindly down the middle of the road when he was just five weeks old. He had such a horrible respiratory infection that his eyes were scabbed shut.

It took months of oral and topical antibiotics to clear up the infections. To this day, one of his eyes is still noticeably dark due to scar tissue and he suffers frequent recurrent respiratory infections.

His rough start in life and all the antibiotics that went with it also left him with one seriously sensitive digestive tract. I have never met a cat as gassy or stinky as him. He also frequently suffers from diarrhea, even without diet change.

All this is to say, I was very hopeful that Super Pet Nutrition Colostrum-LD Powder might help strengthen his gut and immune system.

My Results

I started putting Colostrum-LD in Makoa’s food twice a day about a month ago.

Within a few days of starting the supplement, I noticed he was far less gassy than usual. Within three weeks, he was no longer clearing the couch during cuddle sessions and, amazingly, his stools were completely normal. No more scrubbing the litter box!

During this time, he went through his neuter surgery. I was worried about this since any kind of stress always leaves him with a feline herpes flareup and subsequent respiratory infection. Not only did this not happen while he was on Colostrum-LD, but his weepy eye stopped weeping.

Sovereign Laboratories was kind enough to send a bag of their Colostrum-LD supplement for humans along with the pet version. Since it’s the dead of winter in Colorado and my daughter is in kindergarten, I have been dosing her and me with the product daily for the last month. It helped clear up a nasty stomach bug my daughter had and both of us seem to be faring better than usual this time of year.

My only complaint about this product is that the mylar bag it comes in is tough to reseal. The zip-lock seal is sturdy, which I appreciate, but once powder got in it, I couldn’t get it to fully close again.

But this is a small price to pay for such an effective product.

I can’t say enough good things about Super Pet Nutrition Colostrum-LD Powder.

It has made a huge difference in my cat’s life and spared the rest of the household from his gassiness. I no longer have to clean the litter box immediately after he uses it and his respiratory symptoms haven’t returned since I started the product.

This supplement seems to have really strengthened his immune system and fortified what was a very sensitive gut. I am also a big fan of Sovereign Laboratories’ human colostrum supplements. In fact, I recommend Colostrum-LD for the whole family, furry and human.
