THE DEVELOPMENT JOURNEY OF ORGANIC EGGSHELL CALCIUM – A BREAKTHROUGH ACHIEVEMENT BY VIETNAMESE SCIENTISTS
In science and in life, some journeys begin with a simple question — yet open the door to immense value for the community. The birth of DDA Organic Eggshell Calcium is the clearest proof of this: a product once thought to be “impossible to create” has become a groundbreaking achievement of Vietnamese ingenuity in the field of health care.

Born from a Mother’s Need and the Desire to Create Something Better
The story began 16 years ago, when the founder was preparing to become a mother for the first time.
The need for a type of calcium that could dissolve completely in water — colorless, odorless, easy to mix, easy to drink — became urgent. Yet at that time, the market had virtually no product that met these requirements.
A big question arose:
“Is it possible to create an organic calcium that is truly easy to drink, easy to absorb, and safe for everyone?”
That very concern laid the foundation for a research journey that would span more than a decade.
The Journey to Find an Answer – From a Bold Idea to Unwavering Determination
For nearly 10 years, the founder tirelessly searched for collaborators and experimented with numerous raw materials: seashells, clam shells, animal bones, cassava roots… yet none met the required standards.
Then came the breakthrough idea — extracting calcium from eggshells — and the research journey turned to a new chapter.
Although eggshells contain up to 95% inorganic calcium, the team’s ultimate goal was to transform inorganic calcium into organic calcium, the form most optimally absorbed by the human body.

Three Years of Perseverance in the Laboratory – And the First “Breakthrough Moment”
Sleepless nights, failed experiments, moments when giving up seemed inevitable…
But then, the historic moment arrived:
The first batch of organic eggshell calcium was created — completely soluble in water, colorless, odorless, and nearly tasteless.
Purity test results showed: 99.9% purity — organic calcium (Ca).
It was not just a number. It was joy — the tears of success — the result of more than 13 years of relentless scientific dedication.
From Laboratory to Production Line – The Challenge of Turning “Something Small” into “Something Big”
Scaling up from laboratory experiments to industrial production was an enormous challenge: variations in temperature, pressure, reaction speed, heat transfer, mass transfer…
Just one small deviation could cause an entire production batch to fail.
Yet with perseverance and unwavering effort, the first batch of DDA Organic Calcium was successfully produced — paving the way for bringing a truly Vietnamese scientific product to Vietnamese families.
A Superior Calcium Solution – The Pride of Vietnam
DDA Organic Eggshell Calcium possesses a range of outstanding advantages:
Completely soluble in water
Colorless – odorless – tasteless
Easy to drink – easy to mix with any food or beverage
Superior absorption compared to inorganic calcium
100% natural origin – safe for all ages

This is not only a scientific achievement — it is an expression of love for children, for families, and for the Vietnamese community.
A Journey of Belief, Science, and Vietnamese Pride
The birth of DDA Organic Eggshell Calcium not only brings an optimal nutritional solution to the community, but also affirms that:
Vietnamese people are fully capable of creating scientific innovations that are safe, pure, and of international caliber.
This journey began with a mother’s question, was carried forward by the intelligence of Vietnamese scientists, and has now become a shared source of pride for all of us.
DDA Vietnam will continue to research, innovate, and devote its efforts to delivering premium organic products — serving the health and well-being of Vietnamese families.
