Nutrition unlocked my struggle with sleep

I struggled with chronic insomnia, stress and anxiety for an extended period. They felt intertwined, like the three horsemen of a sleepless apocalypse. My journey led me to the realisation that I wasn’t feeding my brain what it needed to do its job, and ultimately to developing the Smart Supplement and founding Heights.

A better foundation for better sleep

Poor sleep can have an outsized impact on the rest of your life. Many products promise an instant fix, but ignore the root of the problem. If your brain isn’t producing melatonin properly, you’ll always be a step behind.

Give it the nutrients it needs, and help your brain to help you sleep better, naturally.

Why your brain matters

A healthy brain will produce the right amounts of melatonin and serotonin, two hormones essential for a restful sleep. Keeping your brain fed with the right nutrients will let it do its job.

The snowball effect

Addressing common nutrient deficiencies can improve your sleep, but also your mental and physical health. Less stress and anxiety in the evenings makes it easier to relax, leading to better sleep.
