03

Everyday Stress, Cortisol, and Craving Support

With clincally-studied ingredients like KSM-66® Ashwagandha, Steel Core® helps reduce stress-related cortisol, which is commonly linked to stubborn belly fat and emotional eating. The result is a calmer, more balanced path to progress.*

Key Ingredients

We choose ingredients with intention. Every formula is built with clean, effective components that support real routines, real goals, and real life. No shortcuts. No unnecessary extras.

L-Carnitine Fumarate

L-Carnitine helps transport stored fatty acids into the mitochondria where they can be converted into energy. This supports fat burning while also giving your body a natural energy lift without the need for stimulants.

L-Carnitine Fumarate
Morosil™ Sicilian Red Orange Fruit

Morosil is derived from Sicilian blood oranges (Citrus Sinensis) and is clinically studied for its ability to support reductions in abdominal fat. It works by supporting healthy metabolism and helping limit fat accumulation, especially around the midsection.

Morosil™ Sicilian Red Orange Fruit
KSM-66® Ashwagandha

KSM-66® Ashwagandha (Withania Somnifera) (5% withanolides) helps the body better manage stress, which can reduce cortisol-related fat storage in the belly area. It also supports balanced mood and energy, making it easier to stay consistent with your wellness goals.

KSM-66® Ashwagandha
Alpha Lipoic Acid

Alpha Lipoic Acid is a powerful antioxidant that supports healthy blood sugar levels and metabolism. It can help your body use carbohydrates more efficiently, supporting overall body composition and fat loss.

Alpha Lipoic Acid
Paradoxine® Grains of Paradise

Paradoxine activates brown adipose tissue, the type of fat that burns calories to produce heat. This thermogenic effect helps increase daily calorie expenditure and can support reductions in stubborn fat areas.

Paradoxine® Grains of Paradise
CapsiAtra® Dihydrocapsiate (from Sweet Peppers)

CapsiAtra Dihydrocapsiate (Capsicum Annuum) (Fruit) provides a gentle thermogenic boost without the burning sensation of hot peppers. It helps rev up your metabolism naturally, supporting increased energy expenditure and fat-burning — all without stimulants.

What customers are asking

Does Steel Core Actually Work?


Some people will tell you that a fat-burner has to contain caffeine in order to work. We disagree! Steel Core contains premium ingredients that have been shown to boost metabolic burn and target visceral body fat without stimulants. We demand scientific proof for everything we include, and we utilize the dosages supported by research.*

Do I have to have low body fat percentage for Steel Core to work?


Many people have told us that Steel Core was the only supplement that helped them lose those last 10-15 pounds and get truly lean. But the active ingredients in Steel Core can help burn more body fat at every stage of your fitness journey.

Should I take Steel Core on an empty stomach?


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

Is Steel Core stimulant-free?


Yes, Steel Core is completely stimulant-free, making it suitable for those sensitive to caffeine or other stimulants. It supports fat burning without the jittery effects and can be consumed at any time of the day, even before bed.*

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.*
