Some symptoms don’t always mean what we think they do.

Fatigue, weight changes, mood shifts, brain fog, even changes in temperature sensitivity, these are often associated with menopause. But they can also be linked to thyroid function, which is why confusion between the two is more common than many realize.

The overlap can lead people to misinterpret what’s really going on in their bodies.

That’s where understanding the role of the thyroid becomes important.

The thyroid gland uses iodine to produce two key hormones:

  • T4 (thyroxine)
  • T3 (triiodothyronine)

These hormones help regulate:

  • Metabolism (how your body uses energy)
  • Body temperature
  • Heart rate
  • Energy levels

Why iodine matters

Iodine is an essential mineral, meaning your body can’t make it, you have to get it from food. Without enough iodine, the thyroid can’t produce enough hormones, which can lead to issues like low energy or slowed metabolism.

But here’s the nuance, more isn’t always better.

Too much iodine can also disrupt thyroid function, especially when coming from highly concentrated sources like certain sea vegetables.

The takeaway: balance matters.

In a plant-based approach, iodine-rich foods like sea vegetables can support thyroid health, but they’re potent, so a little goes a long way. It’s not about avoiding them, but using them thoughtfully.

When symptoms overlap, it’s not always about guessing, it’s about understanding the bigger picture.
