Performance Whey Protein Blend delivers complete whey protein for muscle recovery and strength, Solnul® Resistant Potato Starch to dramatically boost beneficial gut bacteria and support natural GLP-1 pathways, advanced prebiotic fiber for digestion, and appetite control support — all in a clean, easy-mix formula with no fillers. One scoop in 8–12 oz cold water. Contains milk.
Lean Muscle & Recovery
22g of complete whey protein (isolate + concentrate) delivers all essential amino acids to fuel muscle protein synthesis, accelerate post-workout recovery, and support lean body composition.
Metabolism & Weight Management
Whey protein's thermic effect and Solnul®'s gut-microbiome influence combine to support fat-burning metabolism and healthier weight management — without the crash or bloat.
Gut Health & Microbiome
Solnul® Resistant Potato Starch is clinically shown to increase Akkermansia by 238% and Bifidobacterium by 350% — two of the most important bacterial strains for gut lining integrity, digestion, and metabolic balance.*
Appetite Control & GLP-1 Support
Prebiotic fiber and Solnul® support natural GLP-1 hormone pathways for steadier energy, smoother hunger signals, and sustained satiety between meals — ideal for GLP-1 lifestyles.
Description
Performance Whey Protein Blend is built for people who want more from their protein. Each serving delivers 22g of complete whey protein from a blend of Whey Protein Isolate and Whey Protein Concentrate — the two most bioavailable and well-researched protein sources available — to support lean muscle, recovery, strength, and a healthy metabolism.
What sets this formula apart is the inclusion of Solnul® Resistant Potato Starch, a next-generation clinically studied prebiotic ingredient. Unlike ordinary fiber, Solnul® has been shown in research to dramatically shift the gut microbiome in beneficial directions — increasing Akkermansia muciniphila and Bifidobacterium species, two of the most studied bacterial strains for gut lining integrity, metabolic health, and digestive comfort. This microbiome support also extends to natural GLP-1 hormone pathways, contributing to steadier appetite control and energy balance.
The formula is clean and simple: no fillers, no artificial dyes, no junk. Pink Himalayan Crystal Salt for electrolyte balance, natural flavors, and Stevia Leaf Extract for light sweetness. Blends easily in 8–12 oz of cold water. Contains milk.
Why We Chose This
Most protein powders are one-dimensional — you get amino acids, a flavor, and a lot of filler. This formula takes a different approach, and the reason comes down to two things: the quality of the protein and the addition of Solnul®.
On the protein side, the blend of Whey Protein Isolate and Whey Protein Concentrate is a deliberate choice. Isolate is the fastest-absorbing, most concentrated form of whey — low in lactose and fat, high in leucine, which is the key amino acid trigger for muscle protein synthesis. Concentrate complements it with a broader micronutrient and immunoglobulin profile. Together, they deliver 22g of complete, highly bioavailable protein per serving.
But the real differentiator is Solnul® Resistant Potato Starch. This isn't generic fiber. Solnul® is a clinically studied prebiotic ingredient with a published research profile showing it can increase Akkermansia muciniphila by 238% and Bifidobacterium by 350% after regular use. That matters because Akkermansia is directly linked to gut lining integrity and metabolic function — low Akkermansia is associated with metabolic dysfunction, increased gut permeability, and impaired weight regulation. Bifidobacterium is one of the most studied probiotic-adjacent organisms for digestion, nutrient absorption, and immune function. Driving both up simultaneously through a prebiotic fiber is a meaningful intervention, not a marketing claim.
The GLP-1 connection is real too. Akkermansia and Bifidobacterium both influence enteroendocrine cells in the gut wall that produce GLP-1 — the hormone that signals satiety, slows gastric emptying, and regulates appetite. Supporting the microbiome that produces GLP-1 naturally is an intelligent, foundational approach to appetite control, especially for anyone on a GLP-1 lifestyle or weight management program.
Clean excipients, easy mixing, no bloat, no fillers. This is a protein that earns its place in a serious wellness stack.

How the Formula Works
This formula works across two primary layers — a high-quality protein foundation and a clinically studied prebiotic system — each addressing a distinct dimension of performance and wellness.
- Whey Protein Blend — Isolate + Concentrate: Whey Protein Isolate provides a fast-digesting, high-leucine protein source with minimal fat and lactose — ideal for triggering muscle protein synthesis post-workout. Whey Protein Concentrate adds a broader amino acid and micronutrient profile including immunoglobulins that support immune function. Together, 22g of complete protein per serving covers all nine essential amino acids at meaningful levels for muscle repair, recovery, and lean mass support.
- Solnul® Resistant Potato Starch — Clinically Studied Prebiotic: Solnul® is a patented resistant starch derived from potato that functions as a selective prebiotic — feeding specific beneficial bacteria rather than fermenting broadly. In published research, Solnul® increased Akkermansia muciniphila by 238%, a species critically linked to gut lining integrity, metabolic regulation, and GLP-1 production. Bifidobacterium populations increased by 350%, supporting digestion, nutrient absorption, and immune modulation. Resistant starches also produce short-chain fatty acids (SCFAs) like butyrate during fermentation, which fuel colonocytes and further support gut lining health.*
- Prebiotic Fiber Support — Guar Gum & Xanthan Gum: Beyond Solnul®, Guar Gum adds soluble fiber that slows gastric emptying — contributing to sustained satiety and steadier post-meal blood glucose response. Xanthan Gum provides texture and contributes additional prebiotic fiber activity. Together with Solnul®, these components create a layered prebiotic effect that supports the gut environment consistently.*
- GLP-1 Pathway Support: GLP-1 (glucagon-like peptide-1) is a gut-derived hormone that signals satiety, slows digestion, and supports healthy blood glucose regulation. Akkermansia and Bifidobacterium — both elevated by Solnul® — are directly linked to the enteroendocrine L-cells that produce GLP-1. By supporting the microbial populations that influence GLP-1 secretion, this formula provides a natural, foundational approach to appetite control and metabolic balance.*
- Pink Himalayan Crystal Salt & Stevia Leaf Extract: Pink Himalayan Crystal Salt provides trace electrolytes (sodium, potassium, magnesium) that support hydration and muscle function — particularly relevant post-exercise. Stevia Leaf Extract provides light natural sweetness with no glycemic impact and no artificial aftertaste.

How to Use
Suggested Use: Add one serving to 8–12 oz of cold water and blend or shake thoroughly.
- Cold water blends best — use a shaker bottle or blender for a smooth, lump-free shake; a spoon alone is not recommended
- Post-workout is the most studied window for whey protein — consuming within 30–60 minutes of training supports muscle protein synthesis at its peak
- Can also be used as a morning protein source or between-meal snack to support appetite control and steady energy throughout the day
- For GLP-1 lifestyle users: consistent daily intake helps sustain the microbiome changes driven by Solnul® — prebiotic effects build over time with regular use
- If you are lactose-sensitive, note that this formula contains milk; Whey Protein Isolate is lower in lactose than Concentrate, but individuals with dairy allergies should not use this product
