Top Ten Best Keto Protein Powder Reviews: It’s All About The Low-Carb Options

I’ll be first to admit that when I heard about people doing a keto diet with practically no carb in per day, I was skeptical and thought it was just another fad.

That was until I spoke with a dietician that I regular partner with for my clients. She told me about the entire history and that’s been around for a very long time. So, I was intrigued and decided to eventually give it a try.

I’m not one of those hardcore keto fans, but I regularly go through 3-month cycles of keto, especially if I want to lose a few pounds after Christmas. But the one problem I found is that the majority of supplements in my pantry weren’t suitable.

So, I spent my last keto cycle experimenting with some products that I really think are working well. And to save you the time and expense of having to do the trial yourself, I’ve listed them out below.

If you’re looking for a good flavor to add to your shakes, you’ll like the chocolate brownie taste. The only downside of this is that this protein powder contains a bit of high fructose corn syrup, which is certainly something most people avoid when it comes to their workout smoothies.

When Should You Take Protein Powders?

As you consider the above-mentioned powders, you may be wondering when is a good time to drink your shake or eat your protein cookies. The good thing about protein is that you can have it at any time of the day and still receive its benefits. There are, however, certain times when you can drink it for specific results. If you have certain goals or reasons for your protein shake, consider how and when you should take your powder. Here are some examples:

  • Want an energy boost? Try drinking it in the morning before you hit the gym. A good time to do so is about half an hour before your workout. It can help you to have the energy and mental focus you need to get through your exercise. Not only that, but the effects of the energy boost can last throughout the day so that you can feel energetic and have sharper mental focus throughout the day.
  • Looking for muscle recovery benefits? Protein is also good for your muscle recovery, so a lot of people like to drink it after their workouts. Because you’ve worked your body hard and may have a breakdown of muscle tissue, the right amount of protein can help your tissue repair, which in turn will lead to the gains at the gym that you’re looking for. Some people prefer drinking their shake after a workout, as some protein shakes tend to bloat or fill you up, so this way they avoid working out on what can feel like a full stomach.
  • Bedtime milkshakes are good for you. When you drink a casein protein before sleepy time, you’re providing your body with all the nutrients and good stuff that may have been depleted during your day and workout. It’s also helpful for getting to sleep, which is always beneficial for your workout goals. Just make sure that you’re not drinking a powder with caffeine in it, as this will do nothing good your fitness goals. Sleep is just as important for muscle gain or weight loss as your diet and workout are.

How Much Should You Take

How much protein you should take is largely dependent on the goals that you have in your workout routine and which kind of powder you’re buying. For example, if you’re looking to build clean muscle, but have bought a powder that is high in carbs, you’ll want to avoid drinking too much.

They say that your protein intake for maintaining ketosis is around 0.6g to 0.8 per each pound of lean body mass. Some people may need a bit more protein depending on their level of fitness, weight goals, etc. For many people who are hoping to achieve the perfect balance in their Keto diet goals, 15% of macros should be protein on a daily basis, so it depends on how much you can get from the supplement that you’re drinking.

Most people are fine with one protein shake per day, while others like to drink one in the morning for energy and another later on after their workout for muscle recovery benefits.

Before investing in a protein powder, make sure to pay attention to the facts on what is in the ingredients. You want to be sure that you’re getting one that will help you reach your specific goals for your protein intake.

What Nutrients Are Important

As you can imagine, if you’re hoping to get benefits from your protein powders, you’ll want to make sure that it is high in protein. Some of the better ones offer up to 25g to 30g per serving, which is beneficial in helping you to get a good amount of what should be your daily intake of protein.

Other very beneficial nutrients found in several options are dietary fiber and collagen, which are both very helpful for your overall health, from a healthy digestive system to healthy hair and nails, but they also help your body to absorb the protein and if you’re someone who is drinking protein shakes as supplements for certain meals, then the more vitamins and minerals the better.

If you’re someone who is drinking protein shakes as a supplement for a meal, you’ll want to make sure that it’s full of all the good nutrients, which include everything from a healthy amount of protein to dietary fibers, vitamins, minerals, and collagen. The more nutrition provided by your protein powder, the better, although be careful where the nutrients and protein are coming from.

It’s also important to pay attention to different types of men and women. While most protein powders are fine for both genders, there are some that may be especially beneficial for the ladies thanks to the high amount of collagen and metabolism-boosting proteins found in them.

Some proteins may cause you to bloat or gain weight if they’re milk-based and you have a propensity to weight gain while others are soy-based and if you have a soy intolerance or allergy, you could end up with some serious issues.


There are solutions to your need for more protein in your diet, and they are known as protein powders. The above list is full of our favorite options on the market, from those that have zero carbs to others that have sweetened flavors like chocolate and vanilla.

Some are approved for vegans while others are low-cal options for those who want to avoid putting on fat while trying to get their protein intake on a daily basis.

Whether you shop on Amazon or check out options at GNC, check out these top 10 options before buying to see if you find the ideal one for you. Which protein powder is your favorite?

Hi there, I’m Kate Young and I’m a fitness coach from California, but I now live in Austin. I have been involved in so many different sports over the years, including swimming, running, athletics, gymnastics, rugby (yeas, you read that right), baseball, tennis, and so many more that I have lost count.

I just love competing in sports, but struggled to find the one that I would stick with. So, instead I decided to become a fitness coach as it allows me to work with so many different types of athletes.

I’ve also become heavily involved it diet. The reason for this is that I’ve seen too many athletes fail in their fitness goals because their diet didn’t support it. And I’ve seen just as many people fail in their diets, because their fitness activities weren’t effective.

A lot of my work has involved working up with college tennis teams where I have tailored some endurance type fitness programs. Tennis coaches are great at teaching techniques, but a lot of them struggle with general fitness levels.

And that’s where I come in. On this site I contribute to anything tennis, fitness and diet related, which will help you get to your goals quicker and with more ease. And if you have some very specific questions then why not reach out on one of the social media channels where all of us are very active.

We will be happy to hear your thoughts
