The Supplement Stack Your Doctor Actually Recommends
You’re doing everything right. Working with a provider on hormone optimization, starting a GLP-1 protocol, dialing in your health from the inside out. But there’s a quiet gap between “medically guided” and thriving — and it often comes down to what’s in your supplement cabinet. Most of what’s on pharmacy shelves won’t close that gap. Here’s what actually will.

The Problem With the Supplement Aisle
Walk into any pharmacy and you’ll find hundreds of supplement bottles making big promises. The problem? Studies consistently show that many over-the-counter vitamins and supplements contain far less active ingredient than their labels claim — some a fraction of the stated dose. Fillers, poor bioavailability, and the absence of third-party testing aren’t exceptions in the mass-market supplement world. They’re the norm.
A 2023 analysis published in JAMA Network Open found that supplement labeling accuracy varies widely, with many products falling significantly outside stated potency ranges. When you’re working with a provider to dial in your health, that variability isn’t acceptable.
This matters more when you’re optimizing your hormones or supporting a GLP-1 protocol. Your body is working hard to recalibrate — the last thing you want is a supplement that’s mostly chalk.
The Stack — What Actually Moves the Needle
These are the Thorne products Monday Medical providers most often recommend, depending on your care protocol:
Vitamin D-5,000
Vitamin D is a hormone precursor — not just a vitamin. Supports testosterone production, immune function, mood regulation, and bone density. Foundational for any hormone optimization protocol.
Omega-3 with CoQ10
Omega-3s form the structural backbone of cell receptor sites where hormones bind. CoQ10 supports mitochondrial energy and cardiovascular health. A powerhouse pairing for metabolic and hormonal health.
Basic Nutrients 2/Day
The clean foundation. Formulated for bioavailability — meaning your body absorbs what’s on the label. No fillers, no unnecessary additives. Just the vitamins and minerals your cells use every day.
Berberine
Supports healthy glucose metabolism and insulin sensitivity. A powerful complement to GLP-1 therapy for patients focused on long-term metabolic health and blood sugar balance.
Creatine
One of the most researched supplements in existence. Critical for lean muscle preservation during caloric deficit on GLP-1 therapy. Maintaining muscle as you lose weight is the key to lasting metabolic health.
Hormone Advantage
Contains DIM from cruciferous vegetables, supporting healthy estrogen metabolism. Particularly relevant for women navigating perimenopause and anyone actively optimizing hormone balance.
Ashwagandha (KSM-66): Chronic elevated cortisol directly suppresses testosterone and disrupts the entire hormonal cascade. Thorne’s KSM-66 — the most clinically studied ashwagandha form available — supports healthy cortisol levels and stress response: a subtle but significant piece of the hormone optimization puzzle.
