MANMEOKSUL Reviews

01 / What Makes MANMEOKSUL Different

Made forsulforaphane intake.

MANMEOKSUL focuses on sulforaphane among the compounds that can form from broccoli sprouts.

From ingredient selection through preparation, our research focuses on sulforaphane intake.

From seed to MANMEOKSUL

01
Ingredient selection
We test-grow sprouts and compare ingredients and growing conditions from several farms.
02
Ingredients
We make the powder solely from broccoli sprouts.
03
Preparation method
We study how sulforaphane forms and use those findings to set the preparation method.

Research presentations on sulforaphane formation conditions

The work progressed from ingredient extraction conditions in 2024 to product hydrolysis conditions in 2025.

2024
Ingredient quantification and extraction conditions
Wellbeing200 studied sulforaphane quantification and extraction conditions in broccoli sprouts and presented a poster at the 2024 Korean Society of Food Science and Nutrition conference.
2024 Korean Society of Food Science and Nutrition poster presentation
2025
Study of preparation conditions for sulforaphane intake
8.12 ± 0.02 mg/g
Sulforaphane was measured under specific hydrolysis conditions in a study presented at the 2025 Korean Society of Food Science and Nutrition conference.
The powder was mixed with room-temperature water, microwaved for 20 seconds, and measured after standing at room temperature for 10 minutes.
The team tested MANMEOKSUL powder under different hydrolysis conditions and presented a preparation method for sulforaphane intake.
The MANMEOKSUL preparation method draws on this study.

10 minutes
Let stand for 10 minutes after mixing, then drink.

Concept illustration of glucoraphanin, myrosinase, and sulforaphane in sequence — How sulforaphane forms

Why mix it with warm water?

In warm water, the myrosinase enzyme converts glucoraphanin in broccoli sprouts into sulforaphane.

Glucoraphanin + myrosinase → sulforaphane

Water, temperature, and time affect this conversion.

How much and when?

Drink it in the morning or before bed, at a time that fits your routine.

Some participants reported feeling that they slept better.

Intake interval	Amount per serving	One 500g pouch

Study behind two-day intervals

In an experiment exposing cultured human retinal pigment epithelial cells to sulforaphane for 24 hours, protection against oxidative stress remained elevated for 24–48 hours after the compound was removed. — Cell study · Gao et al., 2001

05 / Why We Do Not Freeze-Dry

Why does MANMEOKSUL avoid freeze-drying?

Freeze-drying can help preserve nutrients, but the best process depends on the plant compounds involved.

Broccoli sprout research shows that processing methods can change levels of phytochemicals, including polyphenols and flavonoids, and antioxidant properties.

06 / Sulforaphane and Cellular Health

Beyond ingredient development,we study appropriate intake levels for different groups.

Redefining healthat the cellular level.

Sulforaphane is a plant compound studied for its role in the KEAP1–NRF2 signaling pathway, which is involved in cellular antioxidant and defense responses.

Cell and animal studies have reported that sulforaphane regulates the expression of antioxidant and defense genes through NRF2-related signaling.
