Reviews – The Best Cutting Supplements
1. Rule 1 R1 Cut 10 – The Best Overall Cutting Supplement
R1 Cut 10 is a powdered cutting supplement that features a fully disclosed label with 10 total ingredients.
One of the stand-out ingredients in this formula is carnitine tartrate, which not only helps transport fat to be burned as energy, but also supports muscle mass.
There are several thermogenic ingredients that include 130mg of caffeine. There are also cognitive ingredients to help elevate focus and improve mood. Not bad for a company that’s mainly known for their protein powders!
The downside is that there are some artificial flavoring and colors. Still, the open-label, well-dosed ingredients, and balanced formula make Rule1 R1 Cut 10 the best overall cutting supplement.
- Features 1g Of L-Carnitine L-Tartrate
- Fully Open Label

- Contains Artificial Ingredients
2. Evlution Nutrition Lean Mode – Best Stim-Free Cutting Supplement
Evlution Nutrition Lean Mode is a stim-free cutting supplement that uses several mechanisms of action to help you lose excess body fat.

This is a great product for anyone that doesn’t want stims. That means you can use it at any time of the day.
The downside is there are no focus ingredients. One of the challenges of fat loss is a lack of focus. Lean Mode is a good cutting supplement that could be great if it included 1-2 focus enhancers. Still, the formula is effective enough to make Evlution Nutrition Lean Mode the best stim-free cutting supplement.

Plus there’s a cortisol blocking complex, a diuretic complex, and a CCK-boosting complex. Finally, there’s a complex that improves the absorption of the entire formula.
The main downside, and it’s a big one, is that each complex is a prop blend. That means you don’t know how much of each ingredient you’re getting. Still, Universal Nutrition Animal Cuts is a complete formula that can offer a total approach to fat loss. That makes Animal Cuts the best all-in-one cutting supplement.

It does this by manipulating insulin, one of the primary hormones in the body.
Freak Show features a strong formula that includes chromium, gymnema sylvestre, cinnamon, and berberine. The downside is the price. It’s a little more costly than competing brands. Still, the clear labeling and generous dosing make 5% Nutrition Freak Show the best GDA cutting supplement.

There’s also white kidney bean extract to help block carbohydrate storage. Also, the label is fully transparent so you know exactly what you are getting.
Overall, this is a good formula that can be an effective addition to your fat loss program.

7. 5% Nutrition Keto aSalt – Best Keto Cutting Supplement
5% Nutrition Keto Salt is a powdered source of bhb salts that help the body achieve a state of ketosis faster.

That’s one of, if not the, strongest doses we’ve seen. There are also ingredients that help the body transport and use stored fat for energy.
This creates a very effective keto-based cutting supplement. One of the great things about Keto aSalt is that it does not use any artificial ingredients. It uses natural flavors and a touch of stevia. The other great thing is that it’s a transparent label.

The use of a diuretic can help you look thinner and more defined. Dry XT features an open-label and 9 ingredients including dandelion, perhaps the most common herbal diuretic.

Buying Guide – How To Choose The Best Cutting Supplement?
What Are Cutting Supplements?
A cutting supplement is any product designed to help you lose excess body fat and look your best. Some people may think of competitive bodybuilding, and that’s fine. Still, others might think of looking great at the beach, and that’s fine too. The bottom line is that when you’re “cut”, you look lean and defined.
Types Of Cutting Supplements
There are several different types of cutting supplements. Let’s take a look at each:
Thermogenic – A thermogenic is usually a stimulant-based cutting supplement that stimulates the process of thermogenesis and increases energy. You may remember from some of my other guides that thermogenesis means increasing body temperature by burning more calories. While not every thermogenic contains stimulants, the most effective ones do.
Stim-Free Cutting Supplements – This is any product designed to burn fat without the use of stimulants.
Keto-Specific – There’s an entire category of keto-related products designed to help your body achieve and stay in a state of ketosis. This is when your body uses stored fat as its preferred source of energy.
Carb Blockers – Several products help block the body’s use of carbohydrates. This means you can eat carbs a little more freely and not have to worry about the excess being stored as fat. The problem with a product like this is that it may lead to excessive carbohydrate consumption and an excuse to overeat.
Thyroid Support – One thing that many fad diets and cutting supplements overlook is the simple fact that the thyroid is a gland in the body that controls the metabolism. (1) If your thyroid is not functioning at peak efficiency, you can have serious problems controlling your body fat levels.
Diuretics – Excess water retention can cause you to look overweight and feel bloated. Getting rid of excess water weight can make a big difference in how you look. It can also be a strong motivating factor because the changes in your appearance can be a great start to your fat loss journey. This is a product that should be specifically used according to the directions.
Appetite Suppressants – Controlling your appetite can make a huge difference in your results. After all, putting the fork down and walking out of the kitchen is one of the keys to effective fat loss. These products can help you do exactly that.
How To Choose The Best Cutting Supplement
The main thing to keep in mind when choosing a cutting supplement is to choose the one that best supports your goals. If you are sensitive to caffeine and other stimulants, you probably shouldn’t use a stim-based thermogenic. On the other hand, if you don’t have a problem with stimulants, it makes sense to go with an effective stim-based thermogenic instead of, say, CLA.
Any supplement you’re considering should contain ingredients that have been studied and are effectively dosed. Your product of interest should also feature full-disclosure labeling so you can see exactly what you are paying for. The best cutting supplements are balanced formulas that can target multiple areas of fat loss. Ultimately, this is the best type of cutting supplement to consider.
The Ingredients You Should Look For
Caffeine – This is the most commonly used stimulant in the world. You’ll find it in quite a few thermogenics. Caffeine stimulates thermogenesis and increases energy. (2, 3)
Capsimax Cayenne Pepper – This ingredient is a trademarked version of cayenne pepper. Cayenne contains capsicum, the active ingredient that gives them their heat. It also stimulates thermogenesis and helps decrease appetite. Capsimax helps prevent the burning sensation that regular cayenne peppers can cause in the digestive tract. (4)
Carnitine – L-Carnitine is synthesized from lysine and methionine, which are two essential amino acids. Its primary function is to transport fatty acids to the cells to be used as energy by the body. There are different forms of carnitine with each form having slightly different benefits besides fat transport. For example, l-carnitine-l-tartrate supports muscle mass and recovery and acetyl-l-carnitine has cognitive benefits. (5, 6)
Synephrine – Also known as bitter orange, synephrine replaced ephedra when it was first banned back in the 90s. It has similar benefits that include thermogenesis and energy but is not as strong, which is one of the reasons it was used. (7)
Yohimbine – Yohimbe is a small tree that originates in South Africa that contains an active ingredient known as yohimbine. While popular as an aphrodisiac, it has received a lot of attention lately because it’s thought to be involved in burning “stubborn” fat. Stubborn fat refers to the last few pounds of fat in areas such as the stomach and lower back. These areas are considered “stubborn” because it takes a lot of effort to lose the fat deposited there. Typically it’s the last to go when you’re getting lean, and it doesn’t want to go without a fight. Yohimbine is also considered to be a stimulant that activates thermogenesis. (8)
Guggul Extract – Common in thyroid support formulas, Guggul is a resin that’s secreted by the myrrh tree located in India, Central Asia, and North Africa. Guggul is used in Ayurvedic medicine for a variety of conditions.
Kelp – This is a form of seaweed that has a high iodine content. Iodine is a mineral that’s important to proper thyroid function.
Ashwagandha – This ingredient is another herb used in Ayurvedic medicine. This ingredient is used in cutting supplements to help lower levels of cortisol, the destructive catabolic hormone that’s released by increased stress. It’s widely believed that excess cortisol can make you fat. That’s not entirely accurate. Stress can lead to overeating, which can lead to fat gain. Cortisol also affects insulin resistance which can also lead to unwanted belly fat. The main problem with cortisol is that it’s a catabolic hormone and that affects muscle mass. To preserve muscle and stimulate muscle growth, you should be in a state of anabolism. Put simply: anabolism is the positive or building phase of metabolism and catabolism is the negative or tearing down phase of metabolism. (9)
Dandelion Extract – An herb commonly used as a diuretic that also contains a wide range of vitamins and minerals. (10)
BHB Salts – BHB, or beta-hydroxybutyrate is a form of ketone body that is mainly used as fuel by the brain, heart, and muscles. They are a common supplement used by keto dieters because it can help them achieve a state of ketosis faster.
The Best Way To Use Cutting Supplements
Since there are many different types of cutting supplements that include several stimulant-based products, the best way to use the cutting supplement of your choice is to follow all label directions. This is especially true of any stim-based product. Most often, you will be directed to begin with a half serving to determine your tolerance. That’s great advice. Otherwise, read the label carefully, and do not increase the dosage above what is recommended.
If fat loss is your goal, cutting supplements can make your efforts much more successful. This guide gives you the best choices. All the products listed are well-dosed and the majority are fully disclosed.
The best overall cutting supplement is Rule 1 R1 Cut 10. It’s a powdered drink that features a balanced formula designed to do what a great cutting supplement should: target fat loss through multiple pathways.
If you don’t want a powder, there’s Jacked Factory Burn XT Black. This is the best thermogenic cutting supplement and features clean, smooth energy from a mix of slow and fast release caffeine. Jacked Factory Burn XT Black also uses several trademarked ingredients for quality and purity.
If you’re not into stims, there’s Evlution Nutrition Lean Mode. This is a stim-free formula that transports fat to be used as fuel, helps control appetite, and stimulates the metabolism so your body burns more calories.
When it comes to cutting supplements, there’s a ton of great choices!
