This product is low in calories, low in carbs and bristling with actionable protein.

The Different types of Keto Protein Powder

  • Whey - Whey is considered by many to be the best type of low carb protein powder for those on the keto diet. While the lactose intolerant will want to give it a pass, for everyone else it digests quickly and is absorbed effectively, rushing much-needed nutrients to hurting muscles.
  • Egg - Egg white is considered “paleo” because it’s been around so long. It’s a very lean type of protein that makes for an ideal supplement. It contains virtually no fat and no carbs and is great for those who are combining keto and weightlifting.

  • Collagen - Collagen is an often the overlooked type, but it is actually an excellent source for supplemental protein for keto dieters. Collagen is low in carbs and fat, and it's essential for promoting healthy skin, bones, hair and nails. Along with muscles.

    Vegan/plant-based - Because they don't eat meat or fish or their byproducts it can be difficult for vegans to get adequate amounts of protein in their diet. But there are actually quite a few plant-based sources of this nutrient out there, and vegan supplements are typically very pure with high rates of bioavailability.

How Much Protein Do You Need on a Low Carb Lifestyle?

It’s not evasion to say that this is a question without a straight answer. That’s because everyone’s protein requirements, even those who are not on the keto regimen, are going to be different depending on their age, weight, metabolism, goals and whether or not there are any mitigating conditions.

That said, to know what the US RDA of protein is for you multiply your body weight (in pounds) by 0.6. This will give you the minimum amount you should be eating (in grams). Keep in mind however that athletes are going to want to increase this amount by 50 to 100 percent.

When Should You Drink It?

There are several schools of thought on this subject but here are the basic options:

  • ​Before working out - This will help provide you with a carbo-kick so that you can power through that portion of the workout when you used to fade.
  • ​Post workout - There is no denying a post workout low carb protein shake is going to help your body repair damaged muscles and build new, stronger ones in their place.

  • Before going to sleep - Taking a keto protein shake before going to bed can help your body repair itself while you sleep.
  • ​First thing in the morning - They don’t call it “break-fast” for no reason. By the time you wake up, you've been without food for as much as a half day. Drinking a low carb protein shake in the morning can go a long way toward setting your day off on the right foot.
