What Are Pre-Workout Supplements?

Before going into all the suggested supplements and ingredients in the supplements, what are pre-workout supplements?

Some might say having a pre workout meal or snack on your own can be helpful and give your body energy as well but sometimes buying a pre-workout supplement is easier as it contains the right amount or the ideal amount of the ingredients it uses that is able to help give a boost to your energy, stamina as well as strength when you workout.

As mentioned above, the supplement can help you achieve your goals during your workout and help you perform well.


Why Take a Keto Pre-Workout Supplement?

A pre-workout supplement contains the right amount of ingredients to provide your body with the right amount of nutrients it needs for a successful and efficient workout.

Usually the ingredients used in the supplements have been well calculated and formulated to help your body by increasing the energy levels, elevate the burning of fat, give you more strength and also improve your blood circulation while you work out. Which will result in an efficient, successful workout and help you reach your target or goals.


When to take Keto Pre Workout Supplement

So now you know what a pre-workout supplement is your question would be when do you take it?

The ideal time would be to consume your supplement at about 2 to 3 hours prior to working out to give your workout its fullest potential to achieve excellent results.

However, if you do not have the time or your forgot to take your supplement, take the amounts in smaller doses. 


What to look for in a Keto Pre Workout Supplement

A regular pre-workout supplement is different from these kind of supplement as the ingredients will vary to suite the keto diet. The lower the sugar and carb content in the supplement the better it is for a keto diet. Hence why it is important to look at the macro levels and ingredients of the supplement before buying it.

The ideal supplement for a keto diet would be low in carbs and have no added sugars. Below are some of the ingredients that are good to include as well.



Beta alanine is an amino acid that is able to increase muscle stores of carnosine. It has been shown in studies that it is the most effective to help short and high intensity exercises as it is able to increase the body’s capacity of exercising and improve muscle endurance and also reduce fatigue in the body.

It is one of the most recommended amino acid to help when it comes to energy level concerns. And it is important to know that it has great results only if it comes in a large concentration or is paired with other energy boosting ingredients as well. Hence why its popularity in many pre-workout ingredients.



Creatine is one of the beneficial ingredients to have in a pre workout supplement. It is not a base ingredient but can benefit the user when consumed.

Creatine is able to improve the strength and help in recovery which is very important to those who are working out often or workout on a regular basis. This is especially helpful when your body is low in glucose as it will be able to help.

On top of that, Creatine can also be used to improve your cellular energy making it very versatile to your body. It is also inexpensive hence why used in many different types of products.

When on a keto diet, your body loses much strength and energy as well and you might feel weak or lethargic during the first couple of days of your keto diet. When using a supplement containing creatine it is able to help your body in the long run to improve your health and and diet as well.



In pre-workout supplements, there are some that contains caffeine and some do not. This is because caffeine is often found in coffee and most pre-workouts are able to be consumed with coffee hence there’s no need for the extra amount of caffeine in the product.

However, here still are products that contain caffeine as it does help you get more energy and focus as well. But do watch the amount of caffeine you are consuming especially those who are a daily coffee drinker. If the supplement you are consuming contains coffee then reducing the dosage of your daily coffee would be ideal.


Citrulline Malate

Citrulline malate is an amino acid, citrulline that is bound with malic acid. It is known to be able to help with improving muscle endurance, help with your muscle soreness and also help with your performance.



Ornithine is also an amino acid and it plays an important role in the “urea cycle”. Other amino acids like citrulline (mentioned above) and arginine also plays a role in the urea cycle. This is a metabolic process in your body that is very important.

There has been studies that say that having ornithine in supplements can help stimulate the fat burning in your body and also help in reducing fatigue. If you workout regularly to lose weight and on a keto diet you are looking to lose weight, having ornithine in the supplement is a great benefit to help in your diet journey. One of the products that has this is Legion Pulse.



Betaine or trimethylglycine is a compound that is very beneficial for those who workout often. It can also be commonly found in beets.
Betaine has been known to be able to increase the muscle strength in your body and also help with muscle endurance which is very helpful to those who are regularly working out.



Theanine is also an amino acid but it is commonly found in tea. As you know tea’s are usually able to calm you down and help with stress as well.

Theanine when taken with caffeine can also help improve your mental cognitive state and also help reduce mental and physical stress in the body. With this, it can help change and improve a person’s mood, attention, focus as well as the alertness. This will definitely help you when working out.

Other than that, it is also able to increase nitric oxide production in the body which helps expand blood vessels and increase the blood flow in the body.


Natural Flavors and Sweeteners

In your supplement you do not want any added sugars in there that could affect your ketosis but you also want a great tasting supplement. Hence make sure that the supplements you take consume sweeteners or flavours that are natural and not artificial.

Natural sweeteners such as stevia and erythritol is common and also suitable for your pre-workout supplement.


No Chemicals or Dyes

Other than looking for good ingredients in your supplements, you might want to look out for harmful or bad ingredients in the supplement. Make sure that your pre-workout supplement does not contain any additives like dyes or other chemicals in the product.

There are pre-workout supplements out there that contains artificial dyes which can bring some unwanted side effects to the body.

BPI Sports Pre Workout Review

Just like Perfect keto, BPI Sports also contains zero carbs making it very much suitable for your keto diet. It has been designed specifically for those on a keto diet as well hence you will be assured that this product will not affect your ketosis state.

BPI contains ingredients such as BHBs and MCTs in it, both being great ingredients that help keto dieters very much to lose weight and also provide energy to the body. MCTs as you know is a type of fat that has been broken down rapidly which helps give your body energy.

The exact amount of BHB and MCTs given in the product are unknown but it is sufficient enough for your body. Having both MCT and BHBs boost yours energy when working out as well as improve your performance.

It also contains CDP- Choline that is a nootropic compound that acts as an acetylcholine precursor. This is a chemical in the brain that helps with focus, alertness and clarity as well. This will cause you to be more alert and focus during your workout which is a good benefit.

However, there is something to note is that BPI does not contain ingredients that help with blood flow, so if this is one of your concerns you might want to look at a different product as well. It is also easy to consume, you can just put a scoop into 8 ounces of water or your preferred sports drink and consume it 15 to 30 minutes before your workout.


Cellucor C4 Pre-Workout Review

Cellucor is also another pre workout supplement that contains 0 grams of sugar or other carbs. It is suitable for keto dieters looking for a workout supplement as the ingredients does not harm ketosis. Cellucor is a great supplement and is targeted for high performance athletes who needs a boost in energy, mental performance and endurance.

This is not a supplement that you would take on a daily basis not for every workout but a supplement you take on the days you need an extra push and want to push your limits to test yourself. It will give your body extra physical and mental strength to help you.

In each scoop of Cellucor it contains 6 grams of citrulline malate and 1.5 grams of creatine nitrate which are great ingredients to help you especially in your pumps. This will definitely help with increasing your reps and also try to add weights also and help you much in your bulking process by shortening the process.

Cellucor comes in few flavours, Cherry Limeade, Icy Blue Razz, Orange Mango, Sour Batch, and Strawberry Watermelon.

However, it is more on the pricey side so if you are on a budget it might not be the one for you. But since it is a product that you do not consume daily and only on days you need the extra push, I would say the supplement is worth a shot.

To consume it just mix 1 scoop of the powder to 10 ounces of water and shake it. You can take the supplement 45 to 60 minutes before your workout in order for you to get the full kick. So do plan the time properly so you get the right amount of time especially on the days you are going to push yourself.


Sheer Strength Pre Workout

Just like Cellucor, Sheer Strength was designed for high athlete performers looking for peak performance. However this supplement is meant to be taken on every session if you’d like unlike Cellucor that does not suggest you to take it on every session just on sessions where you need the push.

Sheer Strength also contains great ingredients like L- citrulline, Taurine, Caffeine, minerals, electrolytes and also it does not contain any carbs which makes it suitable for keto dieters.

As mentioned above, L-citrulline is able to help boost your performance in your workout sessions as it is able to promote blood flow and energy when you workout. It is also very noticable the first time you consume it.

Each container of Sheer Strength comes with 30 servings and it is able to provide your body with the antioxidants and electrolytes it needs while also giving you the focus, endurance and push to have a successful workout.

One thing to take note of is that Sheer Strength does contain artificial flavouring as well which is not very health beneficial. It also does not have a very appealing taste as well.

Sheer strength also offers a 100% money back guarantee policy hence you will be able to get a refund if you are unsatisfied with the supplement.
