Iodine is essential. You have to get it in your diet. And most women, particularly in the UK, are deficient. The reason that matters is because your thyroid, which is this gland in the neck, has to have iodine to work right. So the thyroid produces hormones T3 and T4. Those hormones can't be made properly. And those hormones affect every cell of the body.

So energy, skin, hair, nails, hormonal balance, brain function, weight management because it affects

metabolism as well.

Craig Rose is a marine biologist.

Could seaweed be the secret to everything from firmer skin to better cognitive function and energy?

Welcome to Age Better with me, Liz Earle.

This episode is brought to you by Dr. Seweed.

I really do want to share the knowledge and the tools that can help you thrive in later life by taking action today.

And you will have heard me talking a lot here about nutrients like zinc and vitamin C for skin health,

but iodine?

Yeah, well, maybe that's been overlooked.

Well, Craig Rose is the founder of Dr. Seweed, a supplement brand created to address the growing gaps in our modern nutrition

and educate midlife women about the most essential nutrients. As a marine biologist, he knows

that seaweed is one of the most nutrient-dense foods on the planet and that the iodine it contains

could have a real impact on our skin,

metabolism and brains.

Craig, welcome and we'll come to iodine and collagen too in just a moment.

But we do have to start, I think, with a quick backstory from you on how on earth you've gone

from marine biologist to fabulous supplement brand founder.

Well, thank you very much for having me, Liz.
