The Problem

GLP-1 medications are effective.
They're also brutal on your body.

You eat 20% less

Appetite suppression means fewer calories — and fewer nutrients. Your body starts depleting even if you think you're eating well.

Muscle disappears with fat

GLP-1s don't discriminate. Rapid weight loss strips lean muscle along with fat — leaving you weaker, not healthier.

Nutrient deficiencies take hold

Magnesium, B12, iron, vitamin D — GLP-1 users consistently show depleted levels across the board. Most don't know until symptoms hit.

45% of users quit

Side effects — nausea, fatigue, muscle loss — are the leading cause of discontinuation. Companion nutrition can change that.

The Solution

One shot. Everything your body needs.

DayOne is a daily companion shot formulated specifically for what GLP-1 therapy depletes — protein to preserve muscle, fiber for digestive health, collagen for skin and joints, and a full spectrum of micronutrients to fill the gaps.

What's Inside

Science-backed ingredients.
No filler.

Protein

Preserve lean muscle mass

High-quality whey or plant protein isolate delivers essential amino acids your body can't synthesize on its own. Critical when calories drop — without it, your body burns muscle alongside fat.

Fiber

Keep your gut moving

GLP-1 side effects include constipation and digestive slowdown. A prebiotic fiber blend (inulin, resistant starch) feeds good gut bacteria and keeps things regular — without the gas and bloating of cheap fiber supplements.

Collagen

Protect skin, joints, and connective tissue

Rapid weight loss ages skin and strains joints. Hydrolyzed collagen peptides (Type I and III) support skin elasticity and joint comfort — so the body transformation doesn't come at the cost of how you feel.

Vitamins

Fill the micronutrient gap

B12, Vitamin D3, magnesium, zinc, chromium — the specific nutrients GLP-1 users consistently test low for. A complete micronutrient foundation so your body has what it needs to function, recover, and thrive.

Why DayOne

Built for this moment.
Not retrofitted from something else.

01

Formulated specifically for GLP-1 users

Not a general wellness shot. Every ingredient was chosen based on documented nutrient depletion patterns in GLP-1 patients — the science is recent and specific.

02

Shot format — not a shake, not a packet

Small volume, concentrated dose, portable. No mixing, no refrigeration, no cleanup. Take it before your weekly injection, or first thing every morning.

03

Clean label, transparent sourcing

No proprietary blends hiding doses. No artificial colors or sweeteners. Every ingredient listed with its amount — because GLP-1 users are an educated bunch doing their own research.

04

Companion — not competitor

DayOne works with your medication, not against it. We're not making drug claims or suggesting you skip your prescription. We're filling the gap that the medication creates.

"The gap between what your medication needs and what your diet provides is real. DayOne closes it."

Millions are starting GLP-1 therapy in 2026. Most will struggle. Some will quit. A daily companion shot doesn't just reduce side effects — it changes the outcome.
