You’ve scheduled surgery. Now what?
For most patients, the next step is medical clearance. But being cleared isn’t the same as being prepared.
The time before surgery isn’t just waiting time. It’s preparation time.
Better preparation can support better healing and a stronger recovery.
Medicine calls it prehabilitation. At GlowWell, we call it Surgical Readiness.
Even if you’re healthy and active, surgery is a major stress test for your body.
It’s a major physical event, a lot like running a marathon.
Surgery challenges your:
Muscle
Rapid muscle and strength loss
Cardio
Higher heart + lung demand
Metabolism
Blood-sugar + energy shifts
Immune
Temporary changes in immune defense
Gut
Slower digestion + microbiome disruption
Brain
Fatigue, grogginess + brain fog
Sleep
Disrupted restorative sleep
Stress
Higher physical + emotional stress
No matter the procedure, surgery places many of the same demands on your body.

Surgical Readiness doesn’t come in a single scoop.
It comes from preparing the whole person.
You aren’t just preparing for the operating room. You’re preparing for how you heal on the other side.
One of the largest reviews of prehabilitation included 186 clinical trials and 15,684 surgical patients. Preparation before surgery was associated with fewer complications, shorter hospital stays, and better recovery.ref
For quality of life and physical recovery, the strongest results came from combining:
Nutrition + Exercise + Psychological Support
GlowWell® READY translates these three principles into a clear, day-by-day plan for real life.
WHAT ARE YOU PREPARING FOR?
Two Parts. One Preparation Plan.
Surgery is already overwhelming. Preparing—and recovering—shouldn’t be. We simplified it into two parts: targeted nutrition to fuel your body under stress, and a daily plan so you never have to guess what to do next.
Everyday nutrition is for everyday life. Surgical nutrition is for surgery. You drink electrolytes before working out. You take a prenatal vitamin before getting pregnant. Nutrition before surgery shouldn't be treated like an ordinary day.
And the guide? It takes the uncertainty out of an unfamiliar process. Even if you are active and health-conscious, surgery comes with clinical timelines, fasting windows, and logistics you shouldn't have to navigate on your own. It isn’t generic lifestyle advice—it’s a clear, day-by-day playbook designed to help you prepare with confidence.
The 6 Foundations of Surgical Readiness
Explore how PREP™ Nutrition and the READY Guide work together:
Six core areas. Two parts of one preparation plan.
Explore the six areas01 · Muscle + Strength
Up to ~10% of thigh muscle can be lost in the first week after major abdominal surgery. 9 in 10 patients did not meet their protein needs after major surgery—making recovery even harder than it should be.Muscle researchProtein research
PREP™ Supplies
15g Protein from Whey Protein Isolate · 7g Plant-Fermented L-Arginine · 5g L-Glutamine · Vitamin D3 · Magnesium
Protein and amino acids provide the building blocks for muscle protein synthesis during physical stress. Vitamin D3 and magnesium support normal muscle function.†
Whey protein isolate is highly purified to remove nearly all lactose and fat while keeping all nine essential amino acids. Our L-arginine is fermented from plant-based sources rather than derived from animal protein. L-glutamine is provided in pure, free form. Cholecalciferol (D3) and magnesium bisglycinate are selected for absorption and tolerability.
READY Guide Provides
Protein planning, strength training, and daily movement to build physical reserve before surgery and support mobility during recovery.
02 · Tissue Repair + Healing
Because how you heal is part of the result.
PREP™ Supplies
Protein · L-Arginine · L-Glutamine · Vitamin C · Zinc · Vitamin A · Copper · Selenium
Protein and amino acids provide building blocks for tissue repair. Vitamin C and copper support collagen formation, zinc and vitamin A support normal immune function, and selenium contributes to antioxidant defenses.†
READY Guide Provides
Nutrition, immune-health habits, hydration, and recovery tracking for incision care, tissue healing, and warning signs after surgery.
03 · Gut + Microbiome Health
Support your gut before surgery—fasting, antibiotics, medications, and surgical stress can slow digestion and disrupt the microbiome.
PREP™ Supplies
1.5g Inulin/FOS Prebiotic Fiber · 340mg Humiome® Post LB · 5g L-Glutamine · Zinc · Vitamin A · Vitamin C
Prebiotic fiber nourishes beneficial gut bacteria, while L-glutamine helps nourish the cells lining your intestines. Humiome® Post LB provides postbiotic support for digestive health through heat-stabilized, shelf-stable bacterial components—without live bacteria. Zinc and vitamins A and C support normal tissue health.†
READY Guide Provides
Fiber and fermented-food guidance, hydration, and bowel planning to prepare for digestive changes after surgery, plus walking and bowel-function tracking during recovery.
04 · Cardio + Metabolic Reserve
Surgery and recovery increase oxygen and metabolic demands, challenging your heart, lungs, and energy reserves.
PREP™ Supplies
L-Arginine · B-Vitamins · Magnesium · Selenium · Electrolytes (Sodium & Potassium)
L-Arginine supports nitric oxide production for normal blood-vessel relaxation and circulation. B-vitamins help convert food into usable energy, while magnesium and electrolytes support normal muscle and nerve function and fluid balance. Selenium supports antioxidant defenses.†
READY Guide Provides
Daily walking, heart-and-lung conditioning, breathing exercises, blood-sugar-conscious nutrition, and hydration tracking to build reserve for surgical stress.
05 · Brain + Nervous System
Surgery can disrupt sleep, increase stress, and affect mental clarity. Your brain deserves preparation, too.
PREP™ Supplies
Magnesium · Riboflavin (B2) · Vitamin B6 · Vitamin B12 · Zinc · Choline · Folate · Selenium
Magnesium and B-vitamins support normal nervous-system function. Choline is used to make acetylcholine, a chemical messenger involved in memory and focus. Folate supports normal cell function, while selenium contributes to antioxidant defenses.†
Forms selected with bioavailability and tolerability in mind—including active B2 (riboflavin 5-phosphate) and B6 (pyridoxal 5-phosphate), methylated folate and B12 (methylcobalamin), and magnesium bisglycinate.
READY Guide Provides
Sleep routines, brain training, breathing and calming practices to prepare for surgical stress, plus recovery tracking for mental clarity.
06 · Safety + Surgical Planning
Many surgical teams ask patients to stop certain herbs before surgery because they can affect bleeding, medications, or anesthesia. Proprietary blends can also hide exact amounts. PREP™ uses neither—every dietary ingredient and its amount is disclosed.
PREP™ Supplies
ZERO Herbal Ingredients · ZERO Proprietary Blends · FULL Active-Ingredient Transparency
A fully disclosed formula with clear timing instructions, designed to make your nutritional plan easier for your surgical team to review.
READY Guide Provides
Medication and supplement review, clean habits, pain planning, surgical-team questions, surgery-day logistics, caregiver preparation, and postoperative warning signs.
Because everyday supplements aren’t built for surgery, we created our own standard.

How it works
A surgery date is more than a deadline. It’s an opportunity.
For many people, surgery is a powerful reason to make changes they’ve been putting off. You have a clear goal, a defined window, and a reason to show up for yourself every day.
Two weeks. Small daily actions. A stronger foundation for recovery.

Reserve the SystemAbout traditional surgery nutrition: This refers to the general category of immunonutrition drinks commonly used around surgery. PREP™ is a dietary supplement, not a medical food, and does not replace advice from your care team.
About protein and greens powders: Many everyday protein and greens blends contain herbs or high-dose nutrients on preoperative hold lists that surgical teams routinely ask patients to stop before surgery.
No one should have surgery without preparation.
Meet Dr. Cherie
Founder & Anesthesiologist
The science of surgical preparation has existed for decades. But inside a busy healthcare system, clinicians rarely have the time to guide patients through every step. I built GlowWell to bring that standard of care directly to you.
Preparing for surgery takes real effort, and the payoff doesn't arrive until after the procedure—when it’s already too late to go back and do the work. When the gap between the effort and the reward feels that long, it's natural to wonder if it truly matters.
As an anesthesiologist who sees what happens on both sides of the operating table, I'm here to tell you: the preparation is worth it.
My goal is simple: to help you prepare your body for surgery—and get you back to the people, passions, and everyday moments you love afterward.
Dr. Cherie Long, MD
Board-Certified Anesthesiologist
How I built PREP™
01
I treated surgery like race day.
A surgery patient gets weeks, not years, to prepare.
02
I started where the science was.
The clinical science of surgical nutrition, muscle preservation, tissue repair, and gut health.
03
I asked the people who know.
Surgeons, anesthesia colleagues, nurses, dietitians, physical therapists, pharmacists, and patients.
04
Every ingredient earned its place.
The right form and a meaningful amount.
05
It had to taste amazing.
A plan only works if you drink it.
Wonderful surgeons are picky. They should be.
We built PREP™ with zero blood-thinning herbs, zero secret blends, and exact ingredient amounts so your care team can review exactly what you’re taking.

- Prepared doesn’t mean fearless.
- You may still be nervous.
- Prepared doesn’t mean perfect.
- You may miss a day or have less time than planned.
- Prepared doesn’t mean guaranteed.
- No plan can promise how surgery or recovery will go.
Prepared means
- I knew what to do.
- I asked my questions.
- I made a plan.
- I used the time I had.
From people who prepared
“I still felt nervous, but I felt prepared.”
“I finally knew what questions to ask.”
“Thank you for all your help preparing my dad for the best possible pre-op mind and body. He felt so empowered by your program.”
“I was scheduled six weeks out and had no idea there was anything I could do. Having a daily plan changed how the whole wait felt.”
“I walked in feeling like I’d done everything I could.”
“I stopped feeling like I was just waiting. The goals gave me a sense of control over how everything would go. I felt confident going into my breast reduction.”
“I’m sure I’m further along in my recovery because of your prehab program. I’m still carrying the habits forward.”
You don’t have to be the fittest person in the room. You just have to prepare.
Every patient can be a surgical athlete.

Pre-op visits are tightly focused on medical clearance, anesthesia evaluation, and immediate procedural safety—rarely leaving time for lifestyle, nutrition, or physical conditioning.
Being cleared is not the same as being prepared. Clearance confirms you are medically safe to undergo surgery; preparation builds the physical and nutritional reserve you need to heal and recover.
Prehabilitation is supported by thousands of clinical trials (ERAS, surgical oncology, orthopedics), but busy hospital systems don't have the staffing to deliver it to every patient.
Prehabilitation is an established and growing field, but it isn't yet routine everywhere. Surgical workflows are usually built around the procedure, clearance, and immediate safety tasks; evidence takes time to become standard care, and many practices lack the staff or structure to deliver a multimodal preparation program to every patient. So even when the concept is well recognized, it often isn't formally offered.
Many surgeons and anesthesiologists are familiar with prehabilitation concepts even if the specific term is new to them. GlowWell simply translates this general education into a patient-led daily system, while leaving all individual decisions to your care team. You're welcome to share GlowWell's educational materials if your team has questions — and the most important thing is that they're informed about any supplements or significant lifestyle changes you make before surgery.
PREP™ was formulated by a board-certified anesthesiologist specifically for the weeks around elective surgery. It contains zero blood-thinning herbs and no proprietary blends. All 23 ingredients are disclosed with exact amounts, so your surgical team can review every one.
Take your final serving at least 24 hours before surgery, never on surgery day, and always follow your surgical team’s instructions.
Check with your care team before use if you are pregnant or nursing, have kidney disease, take prescription medications, or have an underlying medical condition.
View the Clinical Ingredient Passport →You’re not too late. Start as soon as you can. The READY Guide adapts to the time you have, and any servings left before surgery can continue after surgery, with your team’s okay.
Most everyday protein, greens, and wellness blends weren’t designed for surgery. Many contain herbs and ingredients that surgical societies and anesthesiologists routinely ask patients to stop before surgery—listed on standard preoperative hold lists (such as SPAQI or ASA guidelines)—such as ginkgo, turmeric, or high-dose vitamin E, or hide amounts inside proprietary blends.
PREP™ has 23 disclosed ingredients, no herbal blend, and meaningful amounts of amino acids like arginine and glutamine. And GlowWell® is more than nutrition: the READY Guide gives you a daily action plan.
You could try. But building your own surgery formula is riskier than it looks.
Supplements don’t require pre-market FDA approval. What’s on the label isn’t always what’s in the bottle, and many add fillers, herbs, or extra doses your surgical team may want you to stop.
Buying it all separately is also more work and often costs more: about $864–$1,115+ once you add the guidance. PREP™ gives you one formula with every ingredient listed, plus the READY Guide.
Your surgical team gets the final say. Share the Clinical Ingredient Passport so they can review every ingredient.
If they ask you to skip it before surgery, ask whether you can take it after surgery instead. The READY Guide’s nutrition, hydration, and eating advice still helps you get stronger.
And if it simply isn’t right for you, The READY Guarantee™ lets you return it within 14 days of delivery for a full refund.
