The Clinical Data Shows

Up to 40% of the Weight You're Losing Isn't Fat. It's Muscle.

This is why the scale drops but your body gets softer, weaker, and harder to maintain long term.

Data represents lean mass as a percentage of total weight lost, measured via DXA (dual-energy X-ray absorptiometry) body composition scans in clinical trial substudy populations. Semaglutide figure sourced from PubMed National Library of Medicine, PMID 38629387, 2025 (link).

What's Actually Happening to Your Muscle (And How Lithe Protects It)

When GLP-1s crush your appetite, your body doesn't just burn fat. It burns muscle right alongside it.

 

Every muscle cell runs on a stored fuel called phosphocreatine.

 

It's what keeps your muscle fibers intact, your body strong enough to carry groceries and take stairs without thinking, and your shape looking toned instead of deflated.

 

On a GLP-1, most women are eating far less than their body needs to keep those stores full. And when the tank runs dry, your body breaks down the muscle itself for fuel.

 

Arms go soft. Thighs lose definition. Butt loses its shape. And everyday movements start feeling harder than they did 6 months ago.

 

Protein and lifting help, but they can't refill what's already empty.

 

Lithe's 5g clinical dose of creatine refills phosphocreatine back into every depleted muscle cell.

 

And the full electrolyte stack (sodium, magnesium, potassium) replaces what your GLP-1 strips out daily so the fuel actually gets used.

 

Your muscle holds. Your strength comes back. Your shape stays.

"I'm down 34 lbs on Wegovy and for the first time my body actually looks toned, not just smaller. My arms have definition again and I don't dread catching my reflection anymore. My friends on the same dose are losing weight but losing their shape too. I started Lithe two months ago and something is genuinely different."

Every Ingredient. Every Dose. Nothing Hidden.

Creatine Monohydrate
5,000 mg

Refills the phosphocreatine stores your muscle cells run on, restoring the cellular battery GLP-1s deplete. Muscle preservation follows as a direct downstream effect.

Sodium
1,000 mg

Restores the primary electrolyte GLP-1s flush out through the kidneys, allowing your cells to retain water and actually use the fuel you're consuming.

Magnesium
66 mg

Powers the Krebs cycle, the cellular energy pathway that GLP-1-induced magnesium deficiency shuts down. Supports deep sleep quality, which is where energy restoration actually happens overnight.

Potassium

200 mg

Works with sodium to maintain the electrical gradient your nerve cells need to fire. Without adequate potassium, the signal from your brain to your muscles gets interrupted before the movement even starts.

Frequently Asked Questions

Won't creatine make me gain water weight and stall my progress on the scale?

This is the number one reason women stop creatine before giving it a chance to work it's magic. The water retention concern comes from loading phases where they instruct you to take 20–25g per day in the first week to saturate your muscles fast. Lithe contains 5,000mg (5g) per day, which is the standard daily maintenance dose. At this dose most women see no meaningful scale increase, and any minor initial fluctuation typically resolves within 1–2 weeks as your muscles fully saturate. The scale may move slightly. Your body composition will move in the right direction.

Is Lithe safe to take with semaglutide or tirzepatide?

Yes. Lithe contains creatine monohydrate and electrolytes. Neither has any known interactions with GLP-1 medications, and creatine alone has over 500 peer-reviewed studies behind it. Multiple GPs and endocrinologists actively recommend creatine and electrolyte supplementation alongside GLP-1 therapy for exactly the muscle-preservation reasons this page covers. If you have pre-existing kidney disease or are on a sodium-restricted diet, consult your doctor before starting.

How long until I feel a difference?

Most women notice the first energy shift within the first days of taking it. The electrolyte blend rebalances mineral levels fast — reduced fatigue, clearer head by afternoon, and mornings that stop feeling like a fight. That's the quick layer.
 

The deeper energy shift comes from creatine saturation, which takes 3-4 weeks at 5g daily to fully load your phosphocreatine stores.

That's when the sustained, all-day energy kicks in — the kind that gets you back to the gym, back to your walks, back to saying yes to things. Muscle preservation follows as a direct downstream benefit of the creatine saturation. Month one starts the process. Month three is when you know it's working. That's why we recommend starting with the 3-month bundle.

I'm already off my GLP-1 or nearing the end of my prescription. Is it too late to start Lithe?

Not at all — and this timing is actually critical. When you stop a GLP-1, the appetite suppression that was depleting your electrolytes and phosphocreatine stores doesn't reverse overnight. Most women coming off the medication still experience residual fatigue, brain fog, and low energy for weeks after stopping — because the cellular depletion that built up over months doesn't reset the moment the drug leaves your system.
 

Starting Lithe now lets you actively refill those stores during the transition period, so the energy recovery happens faster and the worst of the post-GLP-1 fatigue doesn't compound on top of the adjustment.
 

There's also a muscle-preservation argument that matters here: roughly two-thirds of weight lost on a GLP-1 comes back within a year of stopping, and most of it comes back as fat. That's because the lean muscle lost during the drug has permanently lowered your resting metabolism — and muscle is the only thing that reverses that. Lithe's 5g of creatine helps you preserve and rebuild the muscle mass that keeps the weight off long after the prescription ends. The energy and the weight loss protection work together. One scoop handles both.

What if I want to try it first without committing to a subscription?

You can. Every Lithe order (both one-time or subscription) comes with the same 60 day money-back guarantee. Try the first tub, and if you don't see the results you were expecting, send back the container for a full refund. The subscription exists because most women find they want Lithe in their routine for the full duration of their GLP-1 journey and beyond, but you're not locked into anything. Skip, pause, or cancel any time.

Does Lithe only help with muscle preservation? Or are there other benefits?

Lithe is built around two of the most studied compounds in sports science: creatine monohydrate (over 500 peer-reviewed studies) and the sodium-magnesium-potassium electrolyte stack that keeps your cells functional under caloric restriction. While we formulated Lithe specifically to primarly address GLP-1-driven muscle and shape loss, the full blend has been shown to support cognitive clarity, bone density, cellular hydration, exercise recovery, and reduced fatigue. You're not just protecting the muscle holding your shape. You're giving your body two of the most proven compounds in human performance research, dosed for what your body actually needs on a GLP-1.
