What are Non-Stim Thermogenics?
Non-stimulant thermogenics support your body's natural ability to encourage metabolism without relying on stimulants. Ingredients like capsaicin, green tea extract, and L-carnitine may promote metabolic function and appetite control, making them ideal for late-night sessions or anyone avoiding caffeine.
How Do Non-Stim Thermogenics Work?
Non-stim thermogenics function by optimising metabolic pathways rather than stimulating the nervous system. For example, L-carnitine plays a key role in transporting fatty acids into mitochondria, where they’re burned for energy—supporting both fat metabolism and endurance. If you’re looking to further enhance your routine, explore our L-carnitine supplements to complement your non-stim thermogenic stack.
In addition, capsaicin helps generate heat through thermogenesis, and acetyl L-carnitine can also improve focus and mental clarity—perfect for maintaining sharpness during calorie deficits. Learn more about acetyl L-carnitine products and how they fit into a balanced, non-stim plan.
