Steel Core®

Steel Core® 101

What It Is

Steel Core is a stimulant-free, once-a-day fat-burner that targets unwanted fat without putting you on edge. Its physician-formulated provides clinical doses of the most cutting-edge, research-validated, patented ingredients to target the most stubborn visceral body fat.* When nothing else has worked, Steel Core is what you need to try.

What It Does

The six ingredients in each serving of Steel Core work synergistically to convert fat to energy, reduce BMI, boost metabolism, partition carbohydrates, and block fat storage. And it does all this without revving you up with caffeine or other stimulants. Steel Core’s holistic formula even includes the powerful adaptogen ashwagandha to help control stress and cortisol levels.*

Why It's Better

Science-backed: Each serving of Steel Core provides potent ingredients that have been shown in studies to help reduce stubborn visceral fat and boost metabolism. These include L-Carnitine fumarate, Morosil™ Sicilian Red Orange Fruit Extract, ashwagandha root extract, alpha lipoic acid, Paradoxine® grains of paradise extract, and CapsiAstra® from sweet peppers.

Transparent Labeling: Unlike shady store-bought fat-burners, Steel Core doesn’t rely on a proprietary cocktail of ingredients that may or may not be in the researched doses. Our label says exactly what’s in each serving, and how much. No “fairy dusting” here!

No Stimulants: Yes, you can burn fat without caffeine! Steel Core is 100% stimulant-free. That means:

❌ No jitters
❌ No built-up tolerance
❌ No sleep disruption

Multi-pronged Approach: Steel Core’s premium quality ingredients don’t target fat by making you move more. They surround and attack it from multiple fronts to increase fat mobilization, enhance fat oxidation, and control the hormones that contribute to fat gain.

Ingredient Breakdown

L-Carnitine Fumarate

L-Carnitine is an essential, non-toxic, natural nutrient that helps burn fat for fuel. This form of carnitine, known as a highly stable form of carnitine, donates l-carnitine to shuttle fatty acid and assists in transporting it across mitochondrial membranes mitochondria for energy production.*

Sicilian Red Orange Fruit Extract (Citrus Sinensis) (Morosil™)

Designed to support a healthy body composition, is a solid extract containing all the active substances of Moro Orange Juice: anthocyanins (cyaniding-3-O-glucoside), hydroxycinnamic acids (caffeic, cumaric, ferulic, sinapic acid), flavone glycosides (narirutin, hesperidin) and ascorbic acid. These active compounds have been shown to possess an important activity against fat accumulation and obesity.*

Ashwagandha Root Standardized Extract (Withania Somnifera) (5% withanolides) (KSM-66®)

Ashwagandha, also known as Withania Somnifera or Indian Ginseng, is a powerful adaptogen that promotes balance in the body. KSM-66® Ashwagandha is the highest-quality ashwagandha extract on the world market today and has been clinically proven to reduce stress, improve memory and cognition, improve sexual performance, enhance sports performance and control weight management.*

Alpha Lipoic Acid

Known as The Universal Antioxidant, enhances mitochondrial function with a strong antioxidant effect, supporting the functions of L-Carnitine and promoting muscle cell nutrient intake and protein turnover. Alpha Lipoic Acid also helps shift glucose into muscles and away from fat cells, increasing energy and reducing stored fat.*

Grains of Paradise Seed Extract (Aframum Melegueta) (Paradoxine®)

A spice belonging to the ginger family that stimulates brown adipose tissue, boosting metabolism and increasing thermogenesis while decreasing visceral fat in the lower abdomen.*

CapsiAtra® Dihydrocapsiate (Capsicum Annuum) (Fruit)

A compound found in CH-19 Sweet Peppers that activates the sympathetic nervous system via receptors in the GI Tract to Increase Resting Energy Expenditure (REE) and Increase Fat Oxidation (Lipolysis).*

FAQs

Does Steel Core actually work?

Some people will tell you that a fat-burner has to contain caffeine in order to work. We disagree!

Yes, we recommend taking Steel Core on an empty stomach with a large glass of water in the morning.

Do I need to diet or exercise for it to work?

The active ingredients in Steel Core don’t require you follow a specific eating or training style in order to be effective. But you will have more success with any fat-burner – including this one – if you eat properly and exercise regularly.*
