Somewhere in my consultation room, at least once a week, a bag appears. A big one. Inside it: everything a worried family has bought from pharmacies, direct sellers and airport duty-free shops. Fish oil beside collagen beside something with a label in a language nobody in the family reads. The question is always the same. Which of these should I take?
My honest answer is also always the same: let us look at your blood work first, because half of this bag is doing nothing, something in it may be working against your medication, and the one thing your body actually lacks is probably not in the bag at all.
What functional nutrition actually means
Functional nutrition starts from a simple discipline: treat the cause the numbers reveal, not just the symptom that brought you in. Fatigue, poor sugar control, stubborn cholesterol, a weight that will not move: each of these is an output. The inputs live in the blood work, the diet history, the sleep, the medications, the stage of life. So we test before we guess. That is exactly why the screening work at HDC Medical sits beside my consultation work: decisions rest on a personu2019s actual biochemistry, not on trends.
Test, do not guess. A supplement chosen without data is just an expensive opinion.
Where nutraceuticals earn their place
I am not anti-supplement. Used precisely, nutraceuticals are a genuine clinical tool, and I use them in practice to support remission of chronic metabolic conditions. But precisely is the entire job description. In my work a nutraceutical earns its place only when it clears four bars:
- The blood work shows a genuine gap or a mechanism worth targeting, not a vague feeling that more is better.
- The evidence for that specific compound, at that dose, for that condition, actually exists.
- It has been checked against every medication the person takes, because interactions are real and some are serious.
- It has an exit plan. We retest, and when the numbers say the job is done, it retires. A supplement without a review date is a subscription, not a treatment.
The line I will not cross
Food remains the foundation, always. No capsule out-argues a plate that is wrong three times a day. And no nutraceutical replaces medical treatment: anyone who tells a diabetic or a cancer patient to swap their medication for a supplement protocol is not practising functional medicine, they are practising fiction. The version I practise works alongside doctors, which is precisely why HDC Medical was built with doctors in it.
So bring the bag. I mean it. Bring every bottle to your next consultation. We will sort it into three piles together: keeps, maybes, and expensive lessons. Then we will let your blood work, not the brochure, decide what goes back on the shelf.
