Ingredient Spotlight: ProGBB®

What is ProGBB®?

ProGBB® is a trademarked form of Gamma-Butyrobetaine Ethyl Ester Chloride (GBB). GBB is a precursor to L-Carnitine, meaning that it is a compound that the body can convert into L-Carnitine through various enzymatic reactions. It's one of the most thermogenic ingredients you'll find in today's pre-workout supplements.

L-Carnitine plays a crucial role in the transport of fatty acids into the mitochondria. Once inside the mitochondria, fatty acids can be oxidized (burned) to produce energy. For a deeper look at how the body generates energy at a cellular level, check out our elevATP® ingredient spotlight, which covers how natural ATP boosters work alongside compounds like ProGBB®.

What are the benefits of supplementing ProGBB®?

As we mentioned, ProGBB® increases the body's natural carnitine production, making ProGBB® an excellent supplement for anybody looking to increase their body's carnitine stores, which can increase energy production and fatty acid oxidation. This makes it a natural fit within a lean muscle stack where maximising fat burning while preserving performance is the priority.

ProGBB® works particularly well when combined with other metabolic support ingredients. Our MitoBurn® ingredient spotlight covers another powerful fat-oxidation compound — L-BAIBA — that complements ProGBB®'s carnitine-boosting mechanism.

Are there any side effects of using ProGBB®?

Although not everybody may consider this a side effect as you might enjoy it, ProGBB® does massively increase thermogenesis which can greatly increase the amount you sweat!

We're not joking — ProGBB® can leave you dripping with sweat, even if you're just sat at your desk or watching TV.

Before using ProGBB®, consider what you're doing for the next 2-3 hours. If you don't want to be sweating then do not use it! For those who want to harness this thermogenic effect during training, pairing ProGBB® with a performance-focused ingredient like Beta Alanine can help push through fatigue at the same time.
