Every day, we’re bombarded with environmental toxins, from the air we breathe, the water we drink, and the food we eat. Most can have a negative impact on your well-being if you leave your body exposed to them.

But there is one unique “superfood” that can bolster your front-line defense barriers against these toxins. In fact, it has been a reliable nutritional source for thousands of years.

Colostrum, the nutrient-rich fluid released in the early stages of breast-feeding, is often referred to as “liquid gold” due to its highly concentrated nature and vast nutritional benefits.

By supporting your body’s natural defenses against daily pollution and chemicals, both inhaled and ingested, an effective colostrum supplement can strengthen your gut and immune health, enhance skin and hair radiance, help increase athletic performance, and improve mental health and mood.

Key Benefits of Effective Colostrum Powders

Colostrum powder improves gut health by reinforcing the gut wall. This is due to lactoferrin, a powerful protein found in bovine colostrum that’s essential to intestinal health.

Due to a higher protein, fat, carbohydrate, magnesium, and vitamin content than cow’s milk, colostrum benefits your immune system by fortifying the gut lining with added protection.

According to research, colostrum’s chemical properties, specifically its diverse amino acid profile, have demonstrated an ability to help maintain healthy skin cells and revitalize hair health.

Long-term supplementation of colostrum for adults supports a reduction in exercise-related inflammation and the maintenance of lean muscle. Research has revealed a decrease in oxidative stress among highly trained female athletes after taking colostrum supplements.

Colostrinin, a polypeptide derived from colostrum, enhances cognitive markers and helps reduce age-related cognitive decline, according to new research.

But, with so many empty promises in the supplement industry, how do you know which colostrum powder delivers on its claims?

When purchasing a colostrum powder, we recommend sticking with naturally derived formulas that have been third-party tested to ensure high standards and quality control. Here are some additional things to consider:

Key Ingredients in a High-Quality Colostrum Powder

Pure Grass-Fed Bovine Colostrum

A rare and rich source of macro and micronutrients as well as essential vitamins and minerals. Bovine colostrum powder provides strong support for your immune system, digestive tract, muscle maintenance, skin health, and helps reduce everyday oxidative stress. For best results, we recommend choosing a product with at least 2,000 mg of colostrum per 2-gram serving.

Protein

Potent colostrum powders will contain protein in their formulas for optimal results. We recommend choosing a product with at least 2 grams of protein per 2-gram serving.

Watch Out For

Pure Grass-Fed Bovine Colostrum

It’s important to ensure the bovine colostrum supplement you purchase is properly pasteurized. Unpasteurized colostrum may contain bacteria, such as Salmonella, E.coli, or Listeria.

Fillers & Extra Ingredients

An effective colostrum dietary supplement won’t use fillers or additives. A naturally derived formula will deliver consistent and healthy results you can rely on every day for immunity and gut support.

Now that you know what ingredients to look for and what to avoid, it’s also important to keep these additional tips in mind when shopping for a colostrum supplement.
