One of the most common questions I get in clinic is where to start with supplements.
By the time patients come to see me, many are already taking something. Often several things. A mixture of vitamins and minerals, sometimes recommended, sometimes self-selected, and often without a clear structure behind it.
The first step is usually not to add more.
It is to step back and simplify.
In practice, I tend to start with a small number of core nutrients that support thyroid function and general physiology. Not because they are “special”, but because they are the ones that come up repeatedly in both blood work and clinical response.
A few examples:
Selenium and zinc
These are involved in normal thyroid function and play a role in the conversion of T4 to T3, the active thyroid hormone at tissue level.
Vitamin D
Commonly low, particularly in the UK. It plays a role in immune function and is frequently relevant in patients with autoimmune thyroid disease.
B vitamins
Support energy metabolism and cellular function. They are not thyroid-specific, but they are often helpful in the wider picture of fatigue and low energy.
Individually, these are often taken as separate supplements.
In practice, that can become complicated quite quickly.
Different doses, different brands, taken at different times, and often inconsistently.
That is usually where things start to lose clarity.
A simpler approach tends to work better.
Start with a consistent base. See how things respond. Then add in specific nutrients if there is a clear reason to do so.
Not everything for everyone. Not long lists of supplements “just in case”.
Just what is needed, in a way that makes sense.
