6. MT. CAPRA Caprotein

MT. CAPRA Caprotein review

MT. CAPRA Caprotein

If you are looking for an easier to digest casein supplement, try the MT. CAPRA Caprotein, because it’s made with goat milk casein. Goat milk is far easier for your body to digest. While many people have tolerance issues with cow’s milk, goats milk rarely causes issues, and it’s nutrient-dense too! The only issue with goat’s milk is the taste is far different from the cow milk you are used to drinking.

Goat milk has fewer allergens, is less inflammatory, reduces cholesterol, it’s high in calcium, and it allows you to absorb more nutrients! Wow, why aren’t we drinking this stuff? Not everyone likes the taste of this alternative milk, which is the only reason it’s lower on the list; that and several customers complained of a gritty texture. Although, this option does come in vanilla and those with cow milk allergy, may be able to use this viable protein option.

Mix two heaping tablespoons with liquid and shake well to drink. You can add it to smoothies, yogurt, hot cereals, or even baked goods. The powder is even partially predigested with a fermentation process to make it the easiest to digest protein powder, and it comes with beneficial probiotics and enzymes too to improve your gut health. All with a very short ingredient list of goat milk protein, fermented goat milk protein, natural vanilla flavor, and probiotic cultures.

What you don’t get are pesticides, GMOs, or antibiotics, just milk protein from grass-fed goats. It also offers 13 grams of protein for 26 percent of your daily needs. The powder is also high in calcium with no added sugars and very little cholesterol. Get a full dose of all of the amino acids you need with this formula too!

Inside the supplement, you get micellar casein, cocoa, sunflower lecithin, and stevia. One container holds 37 servings if you use one level scoop per serving.

Buying Guide for Casein Protein

Find the right casein supplement to suit your needs, but first, learn about the benefits and side effects. Also, get answers to some of your questions too.

Ingredient

Casein protein is a source of long-lasting amino acids that are easy to digest. Like whey, casein comes from milk, but it’s slower to release, which allows your body to spread out the amino acids over a longer period of time to help your body recover from strenuous workouts. It can also help your body build muscle faster by preserving lean muscle tissue.

Continuing on, casein has a complete set of essential amino acids, unlike plant-based proteins. This is why companies dehydrate parts of milk to make a supplement. Furthermore, anyone can benefit from the supplement, not just bodybuilders or athletes. Most athletes and bodybuilders use whey protein to build muscle because of its fast-acting for extra energy.

Benefits

The main benefit of casein is the slow-releasing amino acids to help build muscle mass and its ability to prevent muscle-wasting, but it has other benefits too. It can also act as a meal replacement or bedtime snack. Moreover, the protein can curb your appetite to help you lose weight.

Also, each amino acid has a different effect and help with vital bodily processes. Essential amino acids cannot be made by the body, and you must eat them in order to get your daily supply. Some of these play important roles in your mood and brain as they are precursors to neurotransmitters, while others affect your metabolism. Casein offers 18 of the amino acids, including essential and non-essential, to help level out practically every aspect of your body!

Last of all, some studies have shown that casein protein may be able to reduce free radicals and lower triglyceride levels, which could help your cholesterol. It can also act as an antibacterial with immunity benefits too that can reduce high blood pressure.

Side Effects

As casein comes from milk, the first side effect is for those with lactose or dairy problems. People who cannot have milk need to avoid both casein and whey protein powders. As a matter of fact, cow’s milk contains more than 20 different allergens, which is why we added a goat’s milk casein option to our list. Healthy individuals without milk allergies very rarely experience complications from casein protein.

Also, goats milk offers the preferable A2 casein, which is usually only found in Jersey and Guernsey cows. Meanwhile, most cows offer A1 casein, which is more likely to have allergens and has the least ill-effect on the body. Finally, while not a side effect, you should look for organic and grass-fed cow casein when possible for the densest nutrient content.

Whey vs Casein

Watch this video to see how these two types of protein stack up against each other:

Questions About Casein Protein Powder

Can casein protein hurt my kidneys?

No. While a myth has spread that too much protein can harm your kidneys, it’s based on people with kidney problems. People who are completely healthy do not need to worry about consuming high doses of amino acids or proteins. Creatinine tends to be stronger in those eating a high protein diet, but when it’s from a natural source, your body is more than capable of handling the acid.

Will casein make me bulky?

Casein protein does not cause bulkiness – lifting weights makes your muscles huge, not the food you eat. What the protein does is helps your muscles to recover from your workouts faster. If you work out a lot on a low protein diet, then your muscles will not be in as good of shape. Think of protein as a salve you put on when you get a cut. It helps to fix the problem faster.

When is the best time of day to take casein protein?

You can eat casein protein any time of day but the best time is at nice because it’s slow acting. If you want to reduce your hunger, you can take it during the day to decrease your appetite. Think of casein as an overnight IV drip of amino acids for your body to speed up healing from a strenuous workout after your body is done moving for the day.

Conclusion

Our favorite casein supplement is the Naked Casein – 5LB 100% Micellar Casein Protein Powder because it contains a single ingredient ready to help your muscles recover. The giant five pounds container offers pure casein without any unnecessary fillers with a two and a half month supply making it a bargain price. Treat your muscles and your appetite with a chocolate-flavored supplement ready to improve your body with amino acids.
