Muscle is metabolically active tissue. It naturally declines with age, and faster during periods of caloric restriction. Most routines are built to move the number on the scale. Few are built to support what's underneath it.
Meet the Ritual
Developed in Seoul in partnership with one of Korea’s leading pharmaceutical-grade manufacturers, it brings together precision formulation and everyday convenience. Five key ingredients deliver muscle and metabolic support in one daily powder packet—with a refreshing pear-yuja flavor that makes it a ritual you'll enjoy.

I thought I was doing everything right. The scan showed I was quietly losing muscle, and muscle is the engine that keeps your metabolism strong. Mine was shrinking.
I was juggling too many supplements and still not getting what I needed. Living in Seoul, I saw how far ahead Korea was in formulation science, so I built Protocol 01 here: one daily ritual, no compromises.

Common Questions
Each ingredient has a specific job, and each is included at a meaningful dose:
We left out filler ingredients so the five that matter can each get a full dose. We choose branded, standardized and third-party tested ingredients wherever possible, so you know exactly what you’re getting in every packet.
It’s for adults who want to support their muscle health, digestion and energy every day, especially if you’re in midlife, eating less, or on a GLP-1. You don’t need to be an athlete, but pairing Protocol 01 with regular movement, especially strength training, helps you get the most out of it. If you’re pregnant, nursing or managing a medical condition, check with your doctor first.
Yes. Protocol 01 was designed with GLP-1 users and people eating less in mind. When you eat less, your muscles and digestion need more support, and the formula covers both. It’s not a weight-loss product and doesn’t replace medical care, so talk to your healthcare provider about adding any supplement.
Protocol 01 is lightly flavored with natural Pear Yuja, a Korean citrus, and it’s crisp and refreshing without being too sweet. It contains no added sugar and no artificial sweeteners, and it’s third-party tested as Non-GMO.
