Core Nutritionals | Shred Non-Stim | 50 Servings

Core Nutritionals Shred is a stim-free thermogenic powder built around one clear formulation philosophy: increase energy expenditure and fat oxidation through non-caffeine pathways while preserving stackability, training flexibility, and label transparency. Instead of relying on a heavy stimulant load to create the illusion of effectiveness, this formula uses six disclosed actives that target thermogenesis, fatty acid transport, sympathetic signaling, and nutrient partitioning from different angles. That matters, because the best non-stim fat burners are not trying to feel like a pre-workout. They are trying to improve the physiology of a cut without sabotaging sleep, recovery, or daily caffeine management.

Acetyl-L-Carnitine HCl leads the formula at 1,000mg. ALCAR is a more neurologically active form of carnitine that supports the transport of long-chain fatty acids into mitochondria for oxidation while also crossing the blood-brain barrier more readily than plain L-carnitine. In practice, that makes it a logical anchor for a non-stim fat-loss formula: it supports energy metabolism and often gives a cleaner, more alert feel without acting like a stimulant. One gram is a meaningful daily dose in a multi-ingredient formula, especially when paired with thermogenic agents that increase demand for fatty acid mobilization and oxidation.

Olive extract is dosed at 250mg standardized to 20% oleuropein, yielding 50mg oleuropein. This brings a metabolic-health and antioxidant angle to the formula. Oleuropein is best known for supporting healthy inflammatory balance, glucose handling, and oxidative stress management, which is useful during calorie deficits where training stress is high and recovery margin is lower. It is not the headline fat burner here, but it improves the overall metabolic environment the rest of the formula is working within.

Coleus forskohlii extract is included at 125mg standardized to 20% forskolin, yielding 25mg forskolin. Forskolin is one of the more interesting physique ingredients because it activates adenylate cyclase, increasing intracellular cyclic AMP. That cAMP signaling is closely tied to lipolysis and thermogenic activity. This is a serious, literature-aligned amount of forskolin rather than a dusting for label decoration, and it pairs well with other ingredients in the formula that elevate calorie burning through separate mechanisms.

CapsiAtra® is dosed at 50mg, which sits at the very top of the published 15-50mg clinical range in the ingredient knowledge base. This is one of the strongest decisions in the entire formula. Dihydrocapsiate is a non-pungent capsinoid from CH-19 sweet peppers that activates TRPV1 receptors in the GI tract, increasing sympathetic activity and brown adipose thermogenesis without central nervous system stimulation. Research supports increases in resting energy expenditure and fat oxidation, and unlike harsh stimulant blends, it does so without the typical caffeine-associated crash, jitteriness, or cardiovascular strain.

Grains of paradise extract is dosed at 30mg standardized to 12.5% 6-paradol, a commonly used research-relevant inclusion in thermogenic formulas. It is associated with increased brown adipose tissue activation and higher energy expenditure, making it highly complementary to CapsiAtra®. Customers often experience this combination as a subtle but noticeable warming effect rather than a stimulant buzz.

ProGBB® is included at 25mg as gamma butyrobetaine ethyl ester HCl. ProGBB is a carnitine precursor often used to intensify thermogenesis and sweating while complementing carnitine-based formulas. At 25mg, this is a moderate but purposeful dose: enough to add a noticeable thermogenic edge without turning the product into an uncomfortable sweat bomb for most users.

The synergy is what makes Shred intelligent. CapsiAtra® and grains of paradise push thermogenesis and energy expenditure. Forskolin supports cAMP-driven lipolysis. ALCAR supports mitochondrial fat transport and clean mental energy. ProGBB® ties back into carnitine metabolism and intensifies the thermogenic feel. Olive extract helps support the metabolic environment underneath the formula. Just as important, the label is fully disclosed with no proprietary blends. In a category full of underdosed, stim-heavy fat burners, that transparency matters.

What should you expect? Day one is not a caffeine jolt. Expect a cleaner, subtler effect: possibly a mild increase in warmth, a bit more sweating during training or cardio, and a more switched-on feel from ALCAR. Over 2-4 weeks of consistent use, the value shows up where serious dieters care about it most: better stackability, better adherence, better tolerance, and a more sustainable thermogenic effect that fits daily use.
