Hey Jajaj,
If you've ever started a ketogenic diet or an intermittent fasting routine and felt worse before you felt better...
You're not imagining it.
The fatigue. The brain fog. The muscle heaviness.
Most people chalk it up to the adjustment period and push through.
But there's something specific happening inside your body during that transition—and once you understand it, the solution becomes obvious.
Here's what's going on...
Every gram of glucose your body stores as glycogen carries with it a significant amount of water.
When you shift to healthy keto or fasting and your body starts burning through that stored glucose, it releases that water.
And with that water goes a mineral your body depends on for almost everything it does.
That mineral is potassium.
This is one of the most common—and most overlooked—reasons people feel flat, foggy, and low-energy in the early weeks of a healthy keto or fasting lifestyle.
It's not weakness. It's not the wrong diet for you.
It's a mineral your body is losing faster than you're replacing it.
And here's why replacing it is harder than most people realize.
Potassium has the highest daily requirement of any essential mineral or vitamin—4700 mg per day for the average adult.
Nothing else comes close.
And less than 3% of Americans are hitting that number, even under normal circumstances.
On healthy keto or during a fasting window, your body's demand runs even higher.
The foods most people instinctively reach for—bananas, potatoes, beans—are loaded with sugar and starch that work directly against a healthy keto lifestyle.
A banana, for example, comes with 27 grams of sugar and delivers a relatively modest amount of potassium compared to what your body needs.
To hit 4700 mg from keto-friendly foods alone, you'd need to consistently eat seven to 10 cups of vegetables every single day...
Along with potassium-rich options like wild salmon, avocados, Swiss chard, and spinach.
That's achievable. But it's a high bar—especially when you're already navigating a new way of eating.
And potassium isn't the only thing working against you.
Potassium and magnesium work as a pair inside the body.
In fact, the cellular pump that moves potassium where it needs to go runs on magnesium.
When you're depleting one, you're very likely running low on the other.
Which means even if you're eating well, without both minerals in sufficient amounts, you're not getting the full benefit of either.
This is exactly why I developed
Potassium Tri-Blend Complex.
Standard potassium supplements have been stuck at 99 mg per serving for decades.
A number that represents roughly 2% of the daily requirement of 4700 mg.
How could it be so low?
Due to an industry convention rooted in decades-old, poorly designed studies.
I refuse to be held back by outdated approaches—you deserve better.
Each serving of
Potassium Tri-Blend Complex delivers 500 mg of potassium—a meaningful daily dose, and substantially more than what you'll find in virtually any other potassium supplement on the market.
But the amount is only part of the story.
Potassium doesn't work alone inside the body.
Getting it into your cells—where it does its job—requires specific cofactors to be present.
That's why I formulated this as a tri-blend, with three targeted ingredients chosen specifically to support how potassium is absorbed and used:
Magnesium: The sodium-potassium pump that runs inside every one of your cells depends on magnesium to function.
Vitamin B6: Supports mineral use throughout the body and plays a direct role in nervous system health.
Taurine: Helps transport potassium into cells and supports cellular hydration, the process that determines how well your cells are nourished at the most fundamental level.
These three cofactors don't just accompany the potassium.
They help it work.
One serving per day—a straightforward way to support the mineral your body is working hardest to hold on to.
