A brand new way to meet your teen's protein and fiber needs.

An innovation in sports nutrition. Give your teens the protein and fiber that packaged snacks leave behind — with 10g of protein, 7g of full-spectrum fiber, and one 3-second pour a day. No powders, no clumping, no mess.

A Teen's Day Runs Long. Their Nutrition Usually Doesn't.

Adolescence is the only time in life protein needs run higher per pound than in adulthood. Add a full school day and a two-hour practice and most teens are running on empty by dinner.

No Time For A Healthy Breakfast

The bus does not wait for eggs. A packet poured into water or juice on the way out the door means the morning starts with 10g of protein instead of nothing.

Post-Lunch Crash

A carb-heavy lunch reliably costs them the hour after it. Fiber slows how quickly sugar is absorbed, which is part of why a meal without it lands harder in fifth period.

Not Nearly Enough Fiber

Around 5% of the US population meets the fiber recommendation, and teenagers are not the exception. We put 7g in the same packet as the protein they already want, which is realistically the only way it gets taken.

Straight From Class To Practice

There is a ten-minute window between the last bell and warmups. A drink they can pour, shake and finish in the locker room fits it. A blender and a scoop do not.

Second Dinner + Raided Pantry

Constant hunger is usually the body asking for more than it got. A growing teen who trains is spending faster than most days can keep up with. 10g of complete protein after practice helps them catch up.

Did you know? Over a third of teens grab a snack within an hour of finishing a meal most days.

Nails That Chip Before They Grow

Nails and hair are among the fastest-growing tissues in the body, so they are often the first place a gap shows up. VERISOL® is clinically studied at 2.5g a day to increase nail growth rate and reduce breakage.

The Science Behind Our Instant Dissolving 8-In-1 Complex

How This Helps*

A growing body that trains needs protein for two jobs at once: growing and recovering. One protein source cannot cover fast, sustained and structural needs, so this uses three.

⚡ Whey Protein Isolate for fast-absorbing protein after practice.

⏳ Cell-Based Cultured Protein for a steadier, sustained release.

🦴 Collagen Peptides for the structural side: joints and connective tissue.

Three Crucial Components To Support An Active Teen

Protein shakes skip the fiber. Fiber supplements skip the protein. Most collagen stops well short of the studied dose. We put all three in one packet, sized for a teenager.

10g
The Build

Complete Protein

10g from grass-fed whey, collagen and culture-based protein, with the full amino acid profile lean muscle is made from. Sized for a teenager, where an adult tub pours 40 to 60g.

7g
The Pace

Fiber

7g spread across five sources instead of one large dose. Soluble fiber slows how fast sugar is absorbed, which is what keeps the afternoon from falling apart.

2.5g
The Finish

VERISOL® Collagen

Clinically studied to increase nail growth rate and reduce breakage. The full dose used in the research.
