For GLP-1 Users
Lose Fat, Not Muscle. Clean Protein for GLP-1.
On Ozempic, Wegovy, or Mounjaro? Up to 40% of your weight loss could be muscle. Primal Core delivers 24g of pure grass-fed protein per sachet — no fillers, no nausea triggers, no bloating. Just the protein your body needs to protect lean tissue.
The Problem
GLP-1 Medications Suppress Appetite. Muscle Doesn't Care.
When you eat less, your body doesn't just burn fat — it breaks down muscle too. Without sufficient protein, GLP-1 users lose the very tissue that keeps metabolism high, bones strong, and energy levels stable. The STEP 1 trial found that nearly 4 in 10 kilograms lost on semaglutide came from lean body mass.
Why Primal Core
Built for Reduced Appetite
Preserve Muscle Mass
Up to 40% of GLP-1 weight loss can be muscle. 24g of complete protein per sachet triggers muscle protein synthesis to protect lean tissue.
Zero GI Triggers
No artificial sweeteners, gums, or soy lecithin — the additives that cause nausea and bloating on semaglutide and tirzepatide.
Pre-Portioned Sachets
Each sachet is exactly 30g. No measuring when appetite is low. Toss in your bag, mix in 30 seconds, hit your protein target.
One Ingredient Only
Grass-fed whey protein concentrate. That's it. No fillers, no flavoring, no seed oils. Every calorie is pure, functional protein.
Resistance-Ready
Pair with resistance training 2–3x/week. Research shows this combination preserves 80%+ of lean mass during GLP-1 weight loss.
Dissolves in Coffee
Blend into your morning espresso for a protein cappuccino. Two birds, one sachet — caffeine and 24g protein without a separate shake.

Questions
GLP-1 & Protein FAQ
How much protein do I need on GLP-1 medications?+
Research recommends 1.2–1.6g of protein per kg of body weight daily for GLP-1 users — significantly higher than the standard 0.8g/kg RDA. For a 75kg person, that means 90–120g of protein per day. This elevated intake is critical because GLP-1 medications can cause up to 40% of weight loss to come from lean muscle if protein intake is too low (Wilding et al., NEJM 2021).
Why do GLP-1 users lose muscle mass?+
GLP-1 receptor agonists like semaglutide and tirzepatide suppress appetite and reduce food intake overall. When caloric intake drops without deliberate protein prioritization, the body breaks down muscle tissue for energy alongside fat. The STEP 1 trial showed that up to 39% of total weight lost on semaglutide was lean body mass — which is why targeted high-protein nutrition is essential.
Is Primal Core whey protein GLP-1 friendly?+
Yes. Primal Core is ideal for GLP-1 users because it delivers 24g of complete protein in a single 30g sachet with zero fillers, zero artificial sweeteners, and zero gums. When appetite is reduced, every calorie matters — and Primal Core is pure protein without the bloating, nausea, or digestive discomfort that additive-heavy powders can trigger on GLP-1 medications.
Can whey protein cause nausea on Ozempic or Wegovy?+
GI side effects on GLP-1 medications are common (40–44% of users experience nausea). Most protein powders make this worse with artificial sweeteners (sucralose, acesulfame-K), thickening gums, and soy lecithin. Primal Core eliminates these triggers — it contains exactly one ingredient: grass-fed whey protein concentrate. Many users report it's the only protein powder they can tolerate on GLP-1 therapy.
How should I time protein intake on GLP-1 medications?+
Distribute protein evenly across 3–4 smaller meals throughout the day, aiming for 25–40g per meal. This approach maximizes muscle protein synthesis (MPS), which research shows peaks at approximately 0.4g/kg per sitting (Schoenfeld & Aragon 2018). Start each meal with protein before carbohydrates to improve satiety and reduce GI discomfort.
Are protein sachets better than tubs for GLP-1 users?+
Individual sachets solve two common GLP-1 challenges: portion control and convenience. When appetite is suppressed, measuring powder from a tub feels like a chore. Each Primal Core sachet delivers exactly 24g of protein — no measuring, no guessing. They're also TSA-compliant and nitrogen-sealed, so you never miss a protein target while traveling.
