All-in-One — Daily Muscle & Metabolic Support.
A patented, clinically studied form of HMB. Supports muscle health and helps reduce muscle protein breakdown.
One of the most studied ingredients in sports nutrition. Supports muscle strength, power, and exercise performance.
A gentle prebiotic fiber from guar beans. Supports gut health and digestive regularity, without the bloat of conventional fiber.
Supports digestion, helping Protocol 01 sit easier as part of your daily routine.
Contributes to normal energy metabolism and nervous-system function — support that matters more as absorption declines with age.
Everyone's timeline looks a little different.
The ritual begins. Ginger and prebiotic fiber (PHGG) help ease you in, supporting digestion from day one.
The ritual starts to feel automatic. B12 helps support steady energy, while PHGG keeps supporting regularity.
The habit is set. A full month of myHMB® supports lean muscle health — and if you're active, it helps with strength and recovery too.
After 30 days: steadier energy, easier digestion, and stronger daily support for your muscles — Protocol 01 working with your body, all day, every day.
Add the powder into 8–10 oz of water.
Stir or shake until fully dissolved.
Enjoy 1 stick daily.
Protocol 01 is Seollae's daily muscle and metabolic support supplement.
It combines five active ingredients — myHMB®, creatine, prebiotic fiber (PHGG), ginger extract, and vitamin B12 — in one easy daily stick designed to support muscle preservation, strength, digestion, and energy metabolism.
We kept the formula intentionally simple. Rather than stacking a long list of ingredients in trace amounts, we chose five — myHMB®, creatine, prebiotic fiber (PHGG), ginger extract, and B12 — and dosed each one with precision.
No proprietary blends. No fillers. Just five ingredients, each chosen to complement one another and dosed at a meaningful level.
That's the difference between a label that looks impressive and a formula that's actually built to work.
HMB, or beta-hydroxy beta-methylbutyrate, is a metabolite of the amino acid leucine. It has been clinically studied for its role in supporting muscle health and helping reduce muscle protein breakdown.
Protocol 01 uses myHMB®, a patented and clinically researched form of HMB.
Creatine is one of the most researched ingredients in sports nutrition, with a long track record for supporting muscle strength, power, and exercise performance.
We paired it with myHMB® so Protocol 01 supports muscle from two angles — creatine for strength and performance, myHMB® for reducing muscle breakdown.
PHGG, or partially hydrolyzed guar gum, is a gentle prebiotic fiber that supports digestive regularity and beneficial gut bacteria.
We chose PHGG because it is generally well tolerated and tends to be gentler than many conventional high-fiber ingredients.
Ginger extract supports digestive comfort, helping Protocol 01 sit easier as part of your daily routine.
It also makes the stick easier to enjoy consistently — and consistency is what actually makes any supplement work.
Vitamin B12 contributes to normal energy metabolism and nervous-system function.
Maintaining adequate B12 becomes increasingly important with age, as the body's ability to absorb it can decrease over time.
Protocol 01 was designed for anyone who wants to protect their muscle as they age, diet, or simply become more intentional about long-term metabolic health.
You don't need to be a bodybuilder or serious athlete to care about muscle. Muscle supports strength, body composition, mobility, energy, and healthy aging.
No — Protocol 01 is built to work alongside them, not replace them.
It stacks well with your protein powder, creatine, or other supplements. But it's not a substitute for the protein and nutrients you get from real food.
Its formula is built for a different job: muscle preservation, gut support, digestive comfort, and energy metabolism.
Yes — Protocol 01 can be taken alongside GLP-1 medications as a daily nutritional companion. It is not a GLP-1 medication itself and doesn't replace prescription treatment.
As GLP-1s support weight loss, they can also make it harder to maintain muscle and get consistent nutrition. Protocol 01 is formulated to help fill that gap — supporting muscle preservation, digestion, and energy metabolism during that process.
Protocol 01 was specifically formulated with muscle preservation in mind, including during periods when maintaining lean mass may be more challenging.
If you're significantly restricting calories or using a prescription weight-management medication, talk to your healthcare provider.
Yes. Protocol 01 is designed to support your routine, not replace it.
Resistance training, adequate protein, balanced nutrition, sleep, and regular movement remain important for maintaining and building muscle. Think of Protocol 01 as another tool in your long-term muscle-health routine.
Protocol 01 is designed as a once-daily ritual. Mix one stick pack with 8–10 fl oz of water and take it once a day.
Consistency matters more than perfection — the goal is to make supporting your muscle part of your everyday routine.
Powders bypass the breakdown hurdles of traditional hard-pressed pills and capsules, allowing active ingredients to dissolve rapidly and absorb more efficiently. Plus, it eliminates pill fatigue, making your daily health ritual effortless and enjoyable.
Yuja is a Korean citrus with real history — it's been grown on the Korean peninsula for centuries and is best known as the base for yuja-cha, a citron tea Koreans have turned to for warmth and comfort through winter for generations. The fruit itself looks like a small, bumpy-skinned grapefruit, but its flavor is something else entirely: bright, tart, and deeply aromatic, somewhere between grapefruit, mandarin, and lemon, concentrated mostly in its fragrant peel.
We paired it with pear for a rounder, more balanced sip — the sweetness of pear softens Yuja's tartness without covering up what makes it distinct. It's a flavor that feels both familiar and new, and a small way to carry a bit of Korean tradition into your daily ritual.
No to all three. Protocol 01 is naturally flavored, with no added sugar and no artificial sweeteners — just Pear Yuja, the way it's meant to taste.
It's also Non-GMO, confirmed through third-party testing by Intertek.
Seollae was inspired by the same precision-driven approach that helped make Korean skincare globally influential.
Korea has made significant investments in biotechnology, pharmaceutical manufacturing, and wellness innovation, and we wanted Protocol 01 to be developed within that ecosystem rather than simply borrowing the language of "K-wellness."
Protocol 01 is formulated and manufactured in South Korea, where Seollae was founded.
We chose to build the product within Korea's advanced wellness and biotechnology ecosystem, with a focus on precision formulation, ingredient quality, and manufacturing standards.
Protocol 01 is launching October 2026.

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 protect what's underneath it.
"I got a DEXA scan at 42. What it showed me changed everything."
I thought I was doing everything right. The scan showed me I was quietly losing muscle — while I thought I was winning, my engine was shrinking.
Living in Seoul, I saw how far ahead Korea was in wellness and formulation science. So I built Protocol 01 here — refusing to compromise on a single ingredient.
