Finding the best protein powder for ketogenic diet or any other low carb diet can be a challenge.

The market is saturated with different products and can be difficult to make a rational decision between them.

The truth is, most supposedly “keto-friendly” protein powders aren’t actually keto friendly. If you're following a keto diet, you already know that you need a moderate amount of protein in your diet.

But if you consume too much protein, your liver will convert some of the protein to glucose to use for energy, which slows the changeover to burning fat for energy.

Protein intake must remain high enough to prevent muscle loss and low enough to not interfere with ketosis.

The key to choosing the right protein powder for keto diet is to choose best quality, low-carb, taste, price and texture ratio, this is also the methodology based on how we evaluated protein powders in this article.

If you are in a hurry, then here is a quick overview of the best protein powers for ketogenic diet:

Optimum Nutrition Hydrowhey is a protein supplement based on hydrolyzed whey protein isolates. Whey protein isolate and hydrolysate are among two of the best protein sources available today.

What makes this protein so ideal is the act that it is even more easily digested by the body than whey alone. It has been labeled as the most advanced protein created by Optimum Nutrition.

What is it made of?

Platinum Hydrowhey is made from hydrolyzed whey protein isolates. Now, that’s a big description that means something simple: the protein powder is breaking larger protein particles down into smaller protein particles which helps the isolates get into your body at a rapid pace, much faster than other protein powders.

 A few of the other ingredients include Leucine, Isoleucine, and Valine. There are also amino acids added into the mix, to give you the benefits of the protein powder in an easily digestible formula.

Ideal for whom?

It is definitely a premium product from a premium brand. If you need high-quality whey protein which will absorb fast, mixes easy and tastes good, this is the one. You get what you pay for.

Rating 8.5/10

Optimum Nutrition Platinum Hydrowhey is one of the best protein powders on the market. That’s because of the hydrolized whey protein isolates, the fast absorption, the added BCAA’s and much more.

The main downside with this product is the price. If your wallet is thick enough, then you should definitely give it a try, if you are more price sensitive then you should look for the alternatives.

What is it made of?

For a protein powder so popular and inexpensive, the ingredients list is surprisingly short: three different forms of whey protein: whey protein isolate, whey protein concentrate, and whey peptides, cocoa, lecithin, natural and artificial flavors, acesulfame potassium, Aminogen, and Lactase. The Gold Standard is ideal for a protein injection between meals, before bed or as a post-workout fix.

Rating 9.0/10

The Gold Standard 100% Whey is a great tasting, well-priced whey protein with an excellent nutritional profile. Optimum Nutrition does not pretend that Gold Standard 100% Whey is the best product in their protein powder lineup, Platinum Hydro Whey – an easily digestible whey hydrolysate is clearly superior, but it is also more expensive. Gold Standard 100% Whey has the best value in their whey protein powder lineup, offering fewer fillers than their Performance Whey product while being less costly than Hydrowhey.

Rating 8.0/10

MRM Veggie Elite Performance Protein is definitely a high-quality protein powder and probably the best whey alternative. The biggest downside is the taste, which can be better when comparing to non-vegan powders. But the taste is the best among plant-based powders available on the market. Also, it is very hard to find high quality with no dairy or soy and a balanced protein profile. At the end of the day, we here in Bodyketosis will still prefer whey protein, as it tastes almost always better and has overall better nutrient profile. If you have any digestive issues or allergies then MRM Veggie Elite Performance is the way to go.
