Youtheory GLP-1 Support Muscle Guard Protein pairs 20g of grass-fed whey with myHMB, calcium and vitamin D, targeting the muscle and bone loss that accompanies rapid weight loss.
Overview
Youtheory is an established wellness brand best known for collagen, and its GLP-1 Support range was launched as a doctor-formulated line. The centrepiece is Muscle Guard Protein, offering 20 grams of grass-fed, pasture-raised whey protein concentrate alongside myHMB, with calcium and vitamin D included specifically to address bone loss.
The bone angle is the interesting part. Muscle loss during GLP-1 treatment gets discussed constantly; bone density loss during rapid weight loss gets discussed far less, despite being a real consideration particularly for older patients and post-menopausal women. Youtheory is one of the few brands in this category to formulate for it explicitly rather than mentioning it in passing.
The myHMB inclusion is also well chosen. Beta-hydroxy beta-methylbutyrate has published research on preserving lean mass, which makes it one of the more defensible ingredient selections in a market full of extracts with thin evidence. Youtheory also sells a GLP-1 Support Multi and Protein Stack for people who want both components together.

Consultation Process
Buy at retail or online
Stocked at Youtheory's site, Amazon and grocery and health food retailers.
Use daily while losing weight
Protein needs are highest during active weight loss, not after.
Combine with resistance training
Protein alone does less for muscle than protein plus resistance work.
Consider the stack if you want the multivitamin
Youtheory sells a Multi and Protein Stack together.
Eligibility
- Adults on GLP-1 medication or otherwise losing weight rapidly
- No prescription or consultation required

- Particularly relevant for older adults and post-menopausal women concerned about bone
- Not a treatment for any medical condition
Provider Involvement and Lab Requirements
Provider Involvement
None at purchase. Youtheory describes the line as doctor-formulated, which speaks to how the product was developed rather than providing you with any clinical input. Tell your prescriber about supplements, particularly if you are already taking calcium or vitamin D.
Lab Requirements
Not required or offered. If bone density is a genuine concern for you, that is a conversation with a clinician about DEXA scanning rather than something a protein powder answers.
Pharmacy Fulfillment and Shipping
Pharmacy Fulfillment
Not applicable. This is a retail supplement sold through mainstream channels.

Frequently Asked Questions
What is in Youtheory GLP-1 Support Muscle Guard Protein?
20 grams of grass-fed, pasture-raised whey protein concentrate with myHMB for muscle preservation, plus calcium and vitamin D for bone health. It contains milk and soy.
How much does it cost?
Around $54.29 at list for a 17.1oz container, though it is frequently discounted to roughly $27.15 at some retailers.
What is myHMB?
A branded form of beta-hydroxy beta-methylbutyrate with published research on preserving lean muscle mass. It is one of the better-evidenced ingredient choices in this category.
Why does bone health matter on a GLP-1?
Rapid weight loss is associated with bone density loss as well as muscle loss, a consideration that gets far less attention than muscle. It matters particularly for older adults and post-menopausal women. Youtheory is one of few brands in this category to formulate for it explicitly.
Is 20g of protein enough?
It is modest for this market. Competitors offer 28 to 30g per serving, and protein needs are elevated during rapid weight loss. You may need more than one serving a day depending on your total intake.
Does it replace GLP-1 medication?
No, and it does not claim to. This is protein and micronutrients aimed at the physical consequences of losing weight quickly, intended alongside prescribed treatment.
Is it HSA or FSA eligible?
Not published as eligible. Protein powders are generally excluded unless prescribed for a diagnosed condition with a Letter of Medical Necessity.
