Can it make you more anxious?

I think it can make some people more anxious, yes.

And that's why things like matcha are better than coffee because they have an extra chemical in there that can calm you down.

So like anything, any food, it's all personalised.

And so when we talk about epidemiology, we're talking about

the average person.

Doesn't mean there aren't exceptions.

So I'm not saying that everybody in the world needs to have coffee, but coffee used to be demonised as something that would give you heart attacks and arrhythmias.

And in fact, the opposite is true.

Epidemiologic speed, you can actually, you get less heart abnormalities, arrhythmias when you drink coffee for reasons we still don't understand.

Second was eat 30 different plants, and that was the basis of our Zoe product, the Daily 30, which has 34 mainly freeze-dried whole plants in it.

And we've recently...

Added some more.

So we added some seaweed, some algae and some kombucha in there.

So they're rare ingredients.

We've got seven different types of mushroom that you wouldn't normally have.

Yes, you add it to food and it's different to most of the other sort of supplements you might see.

It's not instead of food.

It looks more like food than most of the common supplements out there that look like green powders.

We did a big trial of this with about 340 people, comparing it to a probiotic and a dummy one.
