If you’ve spent more than five minutes on wellness TikTok this year, you’ve probably heard someone say their “metabolism is broken.” It’s usually followed by a greens powder, a hormone protocol, or a very dramatic morning routine.
Let’s reset.
Your metabolism isn’t a single switch you turn on or off. It’s the sum of every chemical process happening inside your body right now—converting food into energy, regulating blood sugar, repairing cells, building muscle, balancing hormones. It’s not just about how quickly you burn calories. It’s about how efficiently your body produces and uses energy.
That’s where our Metabolism Stack comes in; rather than chasing one “miracle” ingredient, a stack works with multiple pathways at once — supporting blood sugar balance, mitochondrial function, stress response, and lean muscle maintenance in a coordinated way. Your metabolism isn’t a single pathway—it's a network—so let's treat it like it. Here's the breakdown.
L-Carnitine
L-Carnitine is a compound your body synthesizes from amino acids, and it plays a key role in transporting long-chain fatty acids into the mitochondria — the part of your cells responsible for producing usable energy (ATP) through fatty acid oxidation. Multiple scientific reviews and mechanistic studies identify this transport function as central to fatty acid metabolism and energy production at the cellular level.
Supporting efficient fuel delivery into mitochondria particularly matters when your body shifts between glucose and fat as energy sources — a concept researchers refer to as metabolic flexibility. In states of metabolic inflexibility (such as insulin resistance or obesity), mitochondrial fuel handling can be impaired, and L-Carnitine has been discussed as one of the modulators of these pathways.
Key point: L-Carnitine supports how your cells transport actual fuel for oxidation, which underlies efficient energy production.
B12
Vitamin B12 doesn’t directly create energy (only calories do), but it’s essential in the cellular conversion of nutrients into energy—particularly in pathways that produce ATP and support red blood cell formation and nerve function. Water-soluble vitamins like B12 are part of the B-vitamin family that facilitates energy metabolism at the biochemical level.
When your body lacks adequate B12, the efficiency of energy-producing pathways can suffer—which is why deficiency can show up as fatigue or weakness in clinical settings. While these effects are multifactorial, there’s broad consensus that B12 supports nutrient processing and energy metabolism, even though it doesn’t supply energy itself.
Key point: B12 ensures that once nutrients reach your cells, they can be effectively converted into usable energy and supports processes like red blood cell production that influence oxygen delivery—a critical part of efficient energy metabolism.
Probiotics
Metabolism doesn’t just happen in your cells—it starts with digestion. How your gut handles a meal affects everything that comes after: nutrient absorption, energy release, hunger cues, and how you feel throughout the day.
Probiotics are live microbes that can help support digestive comfort and regularity by interacting with your gut microbiome — the community of bacteria that influences how smoothly digestion runs.
When digestion feels more comfortable and regular...
-
Meals feel easier on your stomach
-
Bloating and gas may be reduced
-
Bowels may feel more predictable
-
Overall GI quality of life improves
Key Point: Metabolism doesn’t just happen in your cells. It starts in your gut. And if digestion feels sluggish or unsettled, that ripple effect shows up everywhere — energy, mood, even motivation to eat well. A metabolism stack that includes probiotics acknowledges something simple but often overlooked: efficient metabolism requires a gut that feels good.
The Bigger Picture
There’s no supplement that replaces sleep, strength training, fiber, or protein. But there are ways to support the systems that keep all of that running smoothly.
Think of our Metabolism Stack as infrastructure; it's foundational support that helps your body do what it’s already designed to do — produce energy efficiently and respond intelligently to stress and fuel. When your metabolism is supported at a baseline, you feel it—not as a spike—but in a steady hum of energy that lasts all day.
