💡News flash: we’ve upped our vitamin D dose

When we began our most recent study back in September, we found out that 78% of people were lacking in vitamin D.

After 9 months of taking the Smart Supplement, what we expected to see was the number of people with shortages pretty much disappear. 

But, in reality, that’s not what happened. 

We saw that 57% of people were still falling short. Even after 9 months of taking double the government-recommended dose of vitamin D in the Smart Supplement, and a long, sunny summer. 

A small improvement, but not enough. 

So, we decided to up our vitamin D dosage to 45mcg

And every future bottle of the Smart Supplement you receive will have this new and improved dose. 

That’s the beauty of producing the Smart Supplement in small batches. So if and when the science says we need to do something different—we can do it, and do it fast.

Why did you start with 20mcg of vitamin D?

Vitamin D is still in the early stages of research. Which means that we’re always discovering new things about it, as the science continues to evolve. So, when we first designed the formula, the science suggested that doubling the government-recommended dose would be enough. But, as our trials showed, it’s not enough. 

How much vitamin D is safe to consume? 

The safe upper level of vitamin D is 100mcg—so we’re still well within the safe limits, even with our new higher dose. 

What’s the government-recommended amount of vitamin D?

According to the government, we only need to supplement 10mcg of vitamin D through the autumn and winter months. But, as you can see from the science, people are still experiencing too low levels of vitamin D, even after taking double that amount. 

Might the formula change again? 

It might! We’re always learning, and studying the effects of the Smart Supplement to make sure it’s having the best possible impact on your brain. We make it in small batches on purpose so we can review the science regularly.
