What Is Casein Protein?

Casein protein is sourced from cow’s milk, similar to whey. It constitutes 80% of the milk’s total milk composition, with the remaining 20% comprising of whey. The amazing ability of casein to gel makes it a distinct and diverse protein supplement.

During digestion, casein thickens as it mixes with the stomach acid. This slows down the digestion rate and allows for a steady discharge of amino acids into the small intestine. This steady and slow stream of amino acids develop an extended, yet low rate of muscle protein synthesis.

What Are Some Benefits Of Taking Casein Protein?

What Are Some Benefits Of Taking Casein Protein?

Casein protein is considered an anti-catabolic supplement which means that it can help reduce the breakdown process of your muscle tissues. This leaves your hard-earned muscle mass intact. Since this form of protein is slow-digesting, it can last longer in your bloodstream to repair and grow your muscles.

You can also benefit from casein protein while you sleep. According to 2012 study, taking casein protein before you sleep can stimulate muscle protein synthesis and boost muscle recovery. Many people also take protein powders to curb their appetite to a specific extent, which can aid with weight loss.

Tips In Taking The Casein Protein Powder Supplement

Tips In Taking The Casein Protein Powder Supplement
  • For a better effect, consider mixing casein with a quick-digesting protein like whey. With this combination, you might get a consistent feed of amino acids and reap the benefits of high leucine.
  • Being a slow-digesting supplement, take casein when you’re without food for a long duration of time. Try drinking right before you sleep to gain weight and build muscles.
  • If you’re consuming casein alone, consider taking a large serving of casein to maximize anabolism. For a 200-pound male, we suggest 40-50 grams of casein protein.

What To Look For

1. Ingredients

What To Look For

If you want a more effective type of casein, look for micellar. This form of casein has the ability to create a clot in the stomach, which produces a slow release of amino acids into the small intestine. For a real premium quality supplement, micellar casein should be pure (100%) and found first on the list of ingredients.

As much as possible, look for natural ingredients without chemical bleaching, growth hormones, and other additives. Avoid fillers like added amino acids and maltodextrin, a form of sugar, because they may not provide the same benefits as a whole casein protein.

2. Cold Processed Formula

What To Look For

When casein protein is cold processed or low-temperature-processed, it keeps most of its vulnerable immune elements and nutrients. This leaves the protein powder loaded with the perfect combination of easily absorbed amino acids, potent antioxidants, and metabolism-increasing peptides.

A cold processed casein protein also means no contamination from chemical detergents, heavy metals, or artificial additives. Some brand, like the Promix Micellar Casein Protein Powder, adds a dash of sunflower lecithin for easier mixing.

3. Price

What To Look For

Just with any other product, you want something that’s not heavy on the pocket. The best casein protein powder shouldn’t only be premium quality, but it should also be wallet-friendly. To get the best value for your money, look for a brand that offers the best quality at the lowest price.

Aside from the price, you may also want to look at the net weight of the product. Ideally, the price should be reasonable for its size. If you can find a brand that offers a large net weight at a lower price, the better.

4. Better Nutrition

What To Look For

A good casein protein powder should have the best nutrition as possible. When you’re confused between two brands, look at the nutrition facts and compare. You want a protein powder that packs a higher protein weight with less fat, sugar, and carbohydrates.
