Best Protein Powders Without Artificial Sweeteners

Artificial sweeteners are usually added to protein powders to make them taste better and enhance texture.

However, numerous studies have shown that artificial sweeteners may promote weight gain, various types of cancer and even brain tumors.

While scientists are still divided on the issue, it’s best to keep yourself safe by ditching artificial sugar.

That’s why in this article, I’ll be showing you the 7 best protein powders without artificial sweeteners!

Why You Should Ditch Artificial Sweeteners?

Before I leave a detailed review on each and every product named, let’s first explore some of the reasons to leave artificial sweeteners behind.

First of all, in most protein powders I’ve tried, they are included in such high amounts, that it completely overwhelms you and worst of all, it leaves a strong tang behind.

While artificial sweeteners are promoted as a sugar substitute, in some people, they may even enhance sugar cravings which leads to a double whammy; you end up consuming both.

Last but not least, artificial sweeteners have numerous health hazards, besides the ones I mentioned at the beginning, such as digestive issues, cardiovascular health and metabolic disorders.

All in all, it’s in your best interest to follow this guide and choose a protein powder that doesn’t include artificial sweeteners!
