5 of The Best Lactose Free Protein Powder

Best Lactose Free Protein Powder

If you need more protein in your diet, choosing the right protein powder can accelerate your gains. But the problem is that many of the top protein powders contain lactose, but don’t worry in this article I will show you the best lactose free protein powders.

What Does It Mean To Be Lactose Intolerant

To put it simply lactose intolerant people can’t eat the sugar that comes from dairy products like milk or cheese, because they can’t digest it. Why can this be a problem for people looking to up their protein they are eating. The first reason is that many forms of protein such as beef protein or other meat proteins is that they are very filling and can as a result be very difficult to eat enough to optimise muscle gain and help you maintain your lean muscle mass. The other reason is that most protein powders contains one dairy which means they are not lactose free protein powders.

But not to worry as actually most forms of whey protein isolate can be eaten by lactose intolerant people as they do not contain any of form of lactose.

Nine Essential Amino Acids

The nine essential amino acids are histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine, and any protein sources which has all of these are considered a complete protein, but why are they important to have? They do many things for your body such as increase energy production, immune system function, nutrition absorption, and many other body functions. Furthermore human bodies don’t normally produce any of these essential amino acids or branched chain amino acids, and you get them from food. This is important as all lactose free whey protein powders have all these.

Because protein powder have all nine essential amino acids we can consider them complete proteins, if you want to learn more about complete and incomplete protein you can read this article called Complete vs Incomplete Proteins: Understanding the Difference

Closing Thoughts

Again my top pick is Iso Why Zero for the reasons I listed in the article. But I realise lactose free protein powders can be expensive, so I going to tell you the absolute best alternative egg protein, or egg white protein. Egg white protein is great for protein with a super low calorie count only being 52 calories for 100 grams of egg white, while giving you 11 grams of protein for that 100 grams, and if you don’t want to handle raw eggs I recommend egg white protein powders, this one by It’s Just it good.

But if you want to go super clean vegan protein powder is also a great option, as more than just being a great source of protein, vegan protein powder has been shown to reduce cholesterol levels and reduce markers of heart disease.
