40g of simply delicious protein
"40g of simply delicious protein !!!! Chocolate & Strawberry are my favorites"
Labrada Lean Body RTD is a 40g protein, 280-calorie ready-to-drink meal replacement shake in a shelf-stable 17 fl oz Tetra Pak carton — no refrigeration needed, no mixing, no prep. Grab it, shake it, drink it. The LeanPro protein blend delivers a combination of fast-acting whey protein peptides, BCAAs, L-Glutamine peptides, and slow-acting casein peptides from a multi-source milk protein base, giving you both immediate and sustained amino acid delivery in a single carton. Zero sugar. Zero trans fat. Gluten free. Lactose free. 5g of FiberPlex prebiotic fiber. 22 vitamins and minerals. Informed Choice certified — independently tested for banned substances. Named the #1 rated protein shake by Forbes Health. Five-time winner of the American Culinary Institute's Gold Medal Taste Award. Founded by IFBB Hall of Famer Lee Labrada, whose guarantee has backed every Labrada product since 1995: "If it's on the label, it's in the bottle." Allergens: Contains Milk and Soy (Lecithin). No free shipping — liquid product.*
Most RTD protein shakes use a single protein source — typically whey protein concentrate or a milk protein blend. Labrada's LeanPro blend is built around a layered protein architecture designed to deliver amino acids across multiple timeframes from a single serving. The blend combines fast-acting whey protein peptides (pre-hydrolyzed whey that absorbs within 30-60 minutes of ingestion), medium-speed whey protein concentrate (absorbed over 1-2 hours), and slow-acting casein peptides and calcium caseinate (which form a gel in the stomach and release amino acids gradually over 3-5 hours). The result is an amino acid delivery profile that begins immediately and continues for several hours — more closely approximating the sustained protein delivery of a whole food meal than a single-source whey shake.†
The milk protein isolate base is ultrafiltered and spray dried — processing that concentrates the native protein fractions while removing most of the lactose. The lactose-free claim reflects this processing step, making Lean Body RTD suitable for most individuals with lactose sensitivity despite being a dairy-derived protein. Soy lecithin is used as an emulsifier to keep the fat (from High Oleic Safflower Oil) and protein in homogeneous suspension — the soy content is lecithin only, not soy protein.†
The research on per-meal protein dosing for muscle protein synthesis has converged on a range of 20-40g per meal as the effective window for maximizing the anabolic response to protein intake in most adults. At 40g, Lean Body RTD is at the upper end of this range — meaningful for larger individuals, older adults (who experience anabolic resistance and benefit from higher per-meal protein doses), post-workout recovery (where muscle protein synthesis demand is highest), and meal replacement situations where the carton is the entire meal rather than a supplement to food.†
The multi-source protein architecture matters at this dose level specifically. Research comparing fast-digesting whey to mixed fast-slow protein combinations at higher doses (30g+) has found that the mixed protein approach sustains elevated muscle protein synthesis for longer — the slow-digesting casein fractions extend the anabolic window beyond the 2-hour peak associated with whey alone. At 40g from the LeanPro blend, you're getting both the immediate spike in blood amino acids and the extended delivery that keeps muscle protein synthesis elevated for hours afterward.†
FiberPlex provides 5g of dietary fiber per carton, led by Fructooligosaccharides (FOS) — one of the most extensively researched prebiotic fiber compounds in the human gut microbiome literature. FOS passes undigested through the small intestine to the colon, where Bifidobacteria and Lactobacillus species selectively ferment it, producing short-chain fatty acids (particularly butyrate) and expanding the population of beneficial bacteria. In a ready-to-drink format — where most competitors deliver zero fiber — the FiberPlex component elevates Lean Body RTD above the category standard, contributing to satiety, digestive health, and blood sugar modulation alongside the protein and fat content.†
Lean Body RTD is packaged in a Tetra Pak carton — the same aseptic packaging technology used for shelf-stable dairy and juice products worldwide. Tetra Pak packaging uses ultra-high temperature (UHT) processing combined with the multi-layer carton (paper, polyethylene, aluminum foil) to create a sterile, hermetically sealed environment that prevents microbial growth without added chemical preservatives. The product is shelf-stable at room temperature until opened — no refrigeration required for storage or transport. This makes Lean Body RTD genuinely portable in a way that refrigerated protein drinks are not: gym bags, desk drawers, car trunks, travel bags, and office cabinets.†
Labrada has updated the Tetra Pak cap to a recyclable, sugarcane plant-based cap — the carton itself is made from FSC-certified paper from sustainably managed forests. For a product consumed at this volume, the packaging sustainability credentials are a meaningful differentiator.†
Lean Body RTD carries Informed Choice certification — an independent third-party testing program specifically designed to verify that sports nutrition products are free from substances prohibited by WADA and major sports governing bodies. Every batch of Informed Choice certified products is tested using validated anti-doping lab methods before it reaches consumers. For competitive athletes in tested sports, this certification provides meaningful additional assurance beyond the standard third-party testing Labrada has conducted since 1995. For recreational athletes and general consumers, it reflects the same quality assurance standard that professional athletes rely on.†
Labrada makes both an RTD and a powder version of Lean Body. The RTD is the right choice when convenience is the priority — no shaker, no water, no scooping, no cleanup, ready instantly anywhere. The powder version (available in larger containers) is the better value per gram of protein and allows more control over mixing liquid and serving size. For most Get Yok'd customers the RTD earns its place as the between-meals or on-the-go option alongside a larger container of powder at home — the RTD for the car, the desk, the gym bag; the powder for post-workout shakes at home where a shaker and water are accessible.†
Shake well before opening. Serve cold for best taste. No mixing or preparation required. Use as a post-workout recovery shake, between-meal high-protein snack, or meal replacement when a whole food meal is not practical. No refrigeration required until opened — store at room temperature in your gym bag, desk, or car. Refrigerate after opening and consume promptly. Contains Milk and Soy (Lecithin). Not for individuals with milk protein allergy. Use this product as a food supplement only — not intended for weight reduction.*
