Best Protein Supplements for GLP-1 Users: Complete Guide

Last updated: February 15, 2026

Key Takeaways

1. GLP-1 medications like Ozempic increase muscle loss risk, with up to 39% of weight loss coming from lean mass if protein stays low.
2. Whey protein isolate works best for GLP-1 users because it has 90%+ protein, absorbs quickly, and contains very little lactose.
3. Ready-to-drink, light options such as carbonated protein sodas suit GLP-1 users better than heavy shakes by easing nausea and matching a lower appetite.
4. Bucked Up Protein Soda leads this list with 25g whey isolate, 100 calories, zero sugar or carbs, and refreshing carbonation that many GLP-1 users tolerate well.
5. Preserve muscle on GLP-1 with 1.5-2g protein per kg daily body weight—get Bucked Up Protein Soda to make that intake simple and enjoyable.

How to Choose Protein Supplements While on GLP-1

GLP-1 users need protein supplements that deliver enough protein without overwhelming the stomach. Aim for 15-30g of protein per serving, less than 5g of sugar, and roughly 100-150 calories. Leucine-rich proteins like whey protein activate muscle-building pathways, which matters when appetite drops and nausea appears.

Whey protein isolate stands out as the top choice for many GLP-1 users. Whey protein isolate contains 90% or more protein by weight and is rapidly absorbed, with most fat and lactose removed through advanced filtration. This process makes isolate easier to digest than whey concentrate, which has more carbohydrates and fats that can worsen GLP-1-related digestive issues.

Ready-to-drink convenience helps GLP-1 users who feel too nauseated or tired to prepare food. The ideal format feels light on the stomach, works on an empty stomach, and uses gut-friendly ingredients that avoid digestive discomfort.

The 7 Best Protein Supplements for GLP-1 Users in 2026

1. Bucked Up Protein Soda

Bucked Up Protein Soda leads this list as a carbonated protein drink that delivers 25g of whey protein isolate in only 100 calories. The light carbonation can ease nausea, and the zero-sugar, zero-carb formula helps prevent blood sugar spikes. This protein soda tastes closer to an energy drink than a shake, without milky heaviness or chalky residue. The caffeine-free formula works any time of day, and the fast-absorbing whey isolate supports muscle preservation for GLP-1 users. Shop now for a protein option created with GLP-1 needs in mind.

2. Premier Protein Clear

Premier Protein Clear offers 20g of protein, 90 calories, and very little sugar. The clear, juice-like liquid often feels easier on the stomach than creamy shakes, although it lacks the carbonation many GLP-1 users find soothing for digestion.

3. Fairlife Core Power Elite

Fairlife Core Power Elite provides 42g of protein from ultra-filtered milk. The higher calories and thicker texture can feel heavy for users with GLP-1-related appetite suppression. Many people tolerate it better after a meal instead of on an empty stomach.

4. OWYN Plant-Based Protein

OWYN delivers 20g of plant-based protein plus added probiotics, giving a dairy-free option for people with lactose issues. Plant proteins usually digest more slowly than whey isolate, which may not support rapid muscle protein synthesis as effectively.

5. Core Power Protein Shakes

Core Power shakes contain 26g of protein in a milk-based formula. The lactose content can aggravate digestive problems for some GLP-1 users, and the creamy texture may feel too heavy during periods of low appetite.

6. Muscle Milk Pro Series

Muscle Milk Pro Series offers 32g of protein with a thick, rich consistency. The higher calories and dense texture often feel difficult for GLP-1 users who already struggle with nausea.

7. Protein2o

Protein2o is a flavored water with 15g of whey protein isolate and zero sugar. The light feel works well for sensitive stomachs. The lower protein content may require multiple servings to hit daily goals, and it does not include carbonation that many GLP-1 users enjoy for nausea relief.

Bucked Up Protein Soda stands apart through its carbonated format, complete amino acid profile from whey isolate, and zero-carb formula that fits GLP-1 users who want muscle support without digestive flare-ups.

Best Protein Type for GLP-1 Users

Why Whey Isolate Works Best for GLP-1 Users

Whey protein isolate gives GLP-1 users fast absorption, very low lactose, and a high biological value. Daily intake of 1.5-2g protein per kg ideal body weight supports GLP-1 users, and whey isolate delivers essential amino acids efficiently for muscle protein synthesis.

Protein Shakes on GLP-1: Light RTDs Work Best

Protein intake remains essential while taking GLP-1 medications. Protein supplements like whey-based shakes are often easier to tolerate than solid foods during nausea and low appetite. Lighter, ready-to-drink options usually sit better than thick shakes and help users stay consistent.

Low Protein on GLP-1 Causes Muscle Loss and Fatigue

Around 20% of muscle mass loss occurs with GLP-1 use, and low protein intake speeds up that loss. Too little protein lowers metabolic rate, reduces strength, and increases fatigue. Aim for 1.2-2.0g protein per kg body weight daily to protect muscle.

Real GLP-1 User Experiences With Bucked Up Protein Soda

Many GLP-1 users describe long-standing struggles with traditional protein shakes, and Bucked Up Protein Soda often changes that experience. One user shared, “The protein sodas far exceeded my expectations. They taste similar to an energy drink and don’t have any weird aftertaste as some other clear whey protein drinks do.” Another user highlighted digestion, saying, “I was shocked at how clean and refreshing it tasted while still packing a serious 25g of protein. Not overly sweet, not artificial-tasting, and zero of that gritty protein mouthfeel.”

Convenience also stands out in user feedback. One person explained, “I need to consume 130g of protein daily, and honestly, I’ve never found a product that made that goal feel this easy. I could knock back multiple cans a day and actually enjoy doing it.” These stories show how the right protein drink can make daily nutrition targets realistic during GLP-1 treatment.

Many GLP-1 users thrive with a simple routine that starts with 25g from Bucked Up Protein Soda in the morning, then adds protein-rich meals or snacks throughout the day.
