I couldn't find the composition I wanted, so I made it myself.

When I worked in video production a long time ago, staying up all night was a daily routine.
As the delivery date approached, my life became even more irregular, and the stress from coordinating opinions with clients added up, so I spent each day in a constant state of tension.
After starting a family, the nature of my stress changed. Stress from parenting, financial burdens, and relationships continued, and the cycle of tension and fatigue persisted.

While searching for ways to manage my daily life, I looked into various health supplements on the market. However, some products did not match the composition and dosage I was looking for, and some contained only a single functional ingredient. There were also products that felt too expensive to take consistently.
Each product had its advantages, but it was difficult to find one that combined the ingredient composition and dosage I valued, along with the convenience of taking it once a day.
So I decided to make it myself.
Seion is a product I created myself because I couldn't find the composition I wanted.

Introducing Seion's first product.

Seion Plus L-Theanine Is On
Seion Plus L-Theanine Is On is a health supplement that contains three functional ingredients in one tablet, designed for daily life filled with repeated tension and fatigue.
L-Theanine 250mg
Rhodiola Extract 200mg
Magnesium 94.5mg
Once a day, one tablet per serving.
One box contains 30 tablets, a 30-day supply.
Seion aimed to accurately convey which functional ingredients and how much of them are in the product, rather than using flashy expressions.

Three things Seion values most.
01. Three functional ingredients in one tablet.
L-Theanine 250mg
L-Theanine isan ingredient that may help relieve tension caused by stress. It is a functional ingredient.
Rhodiola extract 200mg
Rhodiola extract isan ingredient that may help reduce fatigue caused by stress. It is a functional ingredient.
Magnesium 94.5mg
Magnesium isnecessary for energy utilization and for maintaining nerve and muscle function. It is a nutrient.
We have clearly distinguished the functions of each ingredient and made it easy to take with just one tablet a day.
※ The above functional information is recognized by the Ministry of Food and Drug Safety for each ingredient.

02. We have clearly indicated the content of the key functional ingredients.
When looking into health functional foods, the first thing I checked was not only the name of the ingredient but also its actual content.
Seion has clearly labeled the content of the key functional ingredients so you can check it directly on the product.


L-Theanine 250mg


Rhodiola extract 200mg

Magnesium 94.5mg
We will clearly provide the necessary information so that supporters can directly check and evaluate the composition of the product.
03. Designed for convenience with one tablet a day.
We believed that it is more important to take health supplements consistently every day than just once.
Seion L-Theanine Izon is designed so you don't have to split your intake into multiple tablets.One tablet, once a day. It is designed so you can take it this way.
Each box contains 30 tablets, allowing for 30 days of use with one tablet per day.

We checked everything one by one from start to finish.
Seion did not start by simply putting a name on an already finished product and selling it.
We prepared the product by directly checking the composition and content of ingredients, selecting the manufacturer, package design, and revising labeling and advertising reviews.
Since this is our first product, we thought it was more important not to miss anything that needed to be checked rather than rushing to launch.
We will accurately deliver the product composition and manufacturing information, focusing on details that supporters can verify.

Produced according to health supplement manufacturing standards.
Seion L-Theanine Izon is produced in a facility managed according to health supplement manufacturing standards.
We manage the manufacturing process from ingredient receipt, blending, tableting, packaging, and shipping, and deliver the product to supporters after necessary quality inspections.

Hello, I am Ju Yeonwoo, the creator of Seion.
I was not someone who made health supplements from the beginning.
While working in video production, I experienced all-nighters and irregular routines, and after starting a family, I faced the stress of parenting, financial burdens, and social relationships.
I started as a consumer looking for a product I could consistently take, and since it was hard to find the right composition, I decided to plan the product myself.
Seion's first product was not created just to add another item to the market. It started from the standards I personally felt were necessary.
We will continue to clearly communicate the ingredients, content, and manufacturing information of our products to build trust.

Why we chose Wadiz
Seion is not yet a widely known brand.
Rather than simply displaying the product and its price, we wanted to first explain why we created this product and the standards we followed in preparing it.
We believed Wadiz is a place where we can share the beginnings of a new brand and the maker's story with supporters.
Through this project, we want to do more than just sell a product—we want to share the reason Seion was founded and the process behind preparing our products.
We will listen directly to what aspects supporters resonate with and what information they need, and reflect this in our future products and brand management.
On Wadiz, we present Seion L-Theanine Is On with exclusive packages and benefits prepared for our supporters.
