WHEN SCIENCE AFFIRMS WHAT I BELIEVE

Diet • Lifestyle • Supplement Wisely

Every now and then, I read a scientific paper that makes me stop and think: this makes so much sense.

Perhaps that’s the scientist in me.

I studied life sciences at university and later completed my MSc at NUS. Science has shaped the way I think for most of my adult life. I want to understand mechanisms, look at the evidence, and remain curious as new research emerges.

So the DO-HEALTH randomized clinical trial immediately caught my attention.

Researchers followed 2,157 generally healthy adults aged 70 and above for three years, studying three simple interventions: vitamin D3, marine omega-3 and strength exercise.

Individually, none significantly reduced invasive cancer. But when all three were combined, researchers reported a 61% lower hazard of invasive cancer compared with participants receiving none of the three active interventions.

Cancer was an exploratory outcome and the authors rightly called for larger and longer studies. So this is not evidence that vitamin D, omega-3 or supplements prevent cancer.

But the finding fascinated me for another reason.

It was the combination that interested me.

Nutrients weren’t being considered in isolation. They were being studied alongside physical activity.

That beautifully affirmed something I have come to believe over many years: good health is built from many small things working together.

And naturally, it made me think about ODK (Marine Omega, D3 + K2).

Why ODK?

Two of the nutrients studied in DO-HEALTH — omega-3 and vitamin D3 — are central to the formula I spent years developing for my own daily use.

Each ODK capsule provides:

1,000 mg marine fish oil providing 400 mg EPA + 200 mg DHA

Vitamin D3 — 1,000 IU

Vitamin K2 MK-7 — 120 mcg

ODK itself was not studied in DO-HEALTH and the doses are different. I am therefore not attaching the cancer finding to ODK.

Rather, I find it encouraging that researchers are investigating nutrients I independently considered important enough to include in my own general-wellness formula.

Why did I add K2?

K2 wasn’t part of DO-HEALTH, but it was a very deliberate addition to ODK.

Beyond its established role in normal calcium metabolism and bone health, I am fascinated by the emerging science surrounding vitamin K2 and angiogenesis — the regulation and formation of new blood vessels.

Angiogenesis is necessary for normal health and healing, but it is also important in cancer biology. Tumours can stimulate new blood vessels to supply themselves with oxygen and nutrients, which is why angiogenesis itself is already a target in modern cancer treatment.

Experimental research has explored K2’s effects on angiogenic signalling, apoptosis, cell proliferation and other cancer-related pathways.

I find this scientifically exciting.

But it remains emerging research. It does not mean that taking K2 prevents cancer, starves tumours or treats cancer.

For me, it is simply another fascinating reason to keep following the science.

And that is what science is about.

My years in science taught me something important: science isn’t about proving what we want to believe.

It is about observing, questioning and being willing to change our minds as evidence develops.

Sometimes, however, a good study comes along that resonates strongly with conclusions we have reached independently.

DO-HEALTH did that for me and I wanted to share this with you.

It reinforced my decision to formulate ODK around omega-3, D3 and K2, while also reminding me that no supplement stands alone.

ODK isn’t medicine. It wasn’t created to prevent or treat disease.

I created it as a simple, well-designed daily supplement for general wellness — something I am happy to take myself and share with my family.

One capsule. Three carefully chosen nutrients.

And the more science I read, the happier I am with the combination I chose.

Take care of tomorrow’s body today.
