Ab Cuts Sleek and Lean Core Cardio Blast Review

Ab Cuts Sleek  & Lean Core Cardio Blast

Less body fat, greater lean muscle mass, and improved endurance. That’s the kind of healthy weight loss you should be seeking, and that’s the sort of weight loss Ab Cuts says it provides with Sleek and Lean Core Cardio Blast.

Designed to work alongside Ab Cuts Protein, Sleek and Lean Core Cardio Blast is a new product from the popular Ab Cuts line. It’s advertised to increase body fat loss, lean muscle growth, exercise intensity, and endurance.

Because Ab Cuts is so well-established in the weight loss world, any new product in this line is worth looking at. In this review, I’ll cover the Sleek and Lean Core Cardio Blast manufacturers, formula, and pricing.

Who Makes the Ab Cuts Line?

The Ab Cuts line is well-known, but do you know who’s behind it all?

Each Ab Cuts product, including Sleek and Lean Core Cardio Blast, is developed and sold by Corr-Jensen. Based in Centennial, Colorado, Corr-Jensen has been in operation since 2005 and boasts an A+ rating with the Better Business Bureau. Furthermore, Corr-Jensen has no customer complaints on file.

It’s rare to find a supplement company that’s been in business for so long, and rarer still to see a positive track record.

Whether or not Sleek and Lean Core Cardio Blast is effective remains to be seen, but we can be confident its developer engages in good business practices.

What’s in Sleek and Lean Core Cardio Blast?

Now that we know a bit more about the folks behind Ab Cuts, let’s consider their latest product.

Sleek and Lean Core Cardio Blast builds on the foundations of the fat burner Sleek and Lean. It contains a 5307.1 mg-proprietary blend with 15 ingredients. That’s more than 5 grams of vitamins, amino acids, and natural extracts.

I generally don’t like proprietary blends because they make it impossible to judge effectiveness through ingredient quantity. However, given the size of the blend, there’s a good chance Sleek and Lean Core Cardio Blast includes enough of each ingredient to be effective.

For now, let’s consider each ingredient individually.

Cordyceps Sinensis

A fungus found on Asian caterpillars, cordyceps is certainly a unique ingredient. Considered a stimulant and an adaptogen, cordyceps increases energy and stamina, while fighting fatigue. This improves your workouts. However, cordyceps has not yet been tested and found effective in humans.


Arginine is an amino acid often included in workout supplements to facilitate nitric oxide (NO) production. By triggering NO production, arginine helps widen blood vessels to increase nutrient flow throughout the body [1].

Conjugated Linoleic Acid

Now we get to some weight loss aids. Conjugated linoleic acid (CLA) is said to stimulate fat burning without affecting the central nervous system. In fact, CLA both decreases body fat and preserves muscle [2]. However, most CLA benefits are modest and some studies don’t reflect any effects from this extract at all.


I’m assuming this creatine form is creatine monohydrate. A naturally-occurring chemical, creatine can also be made in the laboratory. It’s used to improve exercise performance and increase muscle mass. However, creatine can cause bloating and water retention, so be sure you’re willing to exercise before taking Sleek and Lean Core Cardio Blast.


Another amino acid, citrulline combats muscle weakness and fatigue by increasing energy. Like arginine, citrulline is also a pre-cursor of nitric oxide production.


Taurine is another amino acid, but also a powerful antioxidant. Taurine improves mental and physical performance, while also treating some obesity-related complications. Specifically, taurine treats congestive heart failure and high blood pressure.


Leucine is a branched-chain amino acid, which means it’s an essential nutrient with a “branched chain” chemical structure. These amino acids are considered especially effective in improving exercise performance. Leucine helps reduce protein and muscle breakdown, making it a great addition to a protein supplement.


Another branched-chain amino acid, valine prevents fatigue and improves concentration. It also prevents muscle breakdown as a result of weight loss.


Isoleucine works much like leucine, though it also improves muscle recovery [3]. Like other branched-chain amino acids, isoleucine also prevents muscle breakdown and fights fatigue.


Caffeine is another weight loss aid. A mild stimulant, caffeine triggers greater action in the central nervous system to produce heat, boost metabolism, and burn fat. It also has great benefits for energy production. In a 1978 study, caffeine helped test subjects increase their workout time by 15 minutes [4].

Vitamin B6

Also called pyridoxine, vitamin B6 is another energy booster. It works by regulating sugars, fats, and proteins in the body. Vitamin B6 also regulates androgen production, which means it releases greater testosterone levels. Testosterone can improve lean muscle mass, but in women, it may not be quite so desirable.

Vitamin B12

Vitamin B12 is used both to improve exercise and spur weight loss. This vitamin regulates function in the brain, nerves, and blood cells. It also enhances energy levels and prevents fat gain.


L-carnitine is the last amino acid in the Ab Cuts Sleek and Lean Core Cardio Blast formula. Shown to possess significant weight loss properties, l-carnitine is proven to reduce fat mass and increase muscle [5]. It also supports energy production.

Coleus Forskohlii

This plant extract contains the chemical forskolin—a powerful fat burner. In a 2005 study, forskolin decreased body fat percentage and fat mass by a significant amount [6].

Raspberry Ketone

Finally, raspberry ketone burns fat while preserving lean muscle mass. Although scientific evidence on raspberry ketone’s effectiveness is mixed, many believe it boosts metabolism and triggers fat burning. In a 2004 study, overweight mice fed raspberry ketone showed a significantly lower fat mass than mice in the control group [7].

These ingredients are pretty powerful workout boosters. Together, they’ll help you take a more well-rounded approach to weight loss. However, with ingredients that boost testosterone production and increase water retention, this formula may not be for everybody.

How Much Does Sleek and Lean Core Cardio Blast Cost?

Ab Cuts Sleek and Lean Core Cardio Blast retails from a variety of locations with a standard price of $39.99. On, you can find it for $31.99 if you have a GNC Gold Card.

With time, the price will probably drop, but for now, this isn’t a bad price on a weight loss supplement.

Each bottle will last 30 days, so you’re spending a little more than a dollar a day for weight loss.

Is Sleek and Lean Core Cardio Blast Worth a Shot?

Sleek and Lean Core Cardio Blast seems best for dieters looking to gain muscle and drop body fat. Because certain ingredients cause bloating and increased T-levels, it may be better for dedicated bodybuilders or men on a diet than for dieters in general.
