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.

How Heights differs from traditional supplements

Simply the best

We go to great lengths to ensure the quality of all 20 vitamins and minerals in the Smart Supplement. Our capsules are clean, 100% vegan, and free from any fillers or contaminants—designed so the nutrients have the highest impact.

Because you deserve to feel your best.

Bigger impact, better value

Quality nutrition isn’t cheap. We investigated and found that, bought separately, our ingredients would set you back £105 a month, with 14 pills a day. With Heights’ unique formula, you get the same for £30 and 2 capsules a day. And, if it’s in Heights, you don’t need to get it from anywhere else.

Multiple different supplements and pills

5-a-day doesn’t cut it

Five portions of fruit and veg is a great starting point, but it’s just a first step. And 76% of adults in the UK don’t even manage that. In fact, we found that 99% don’t get the full set of nutrients their brains need. Do you?

Consistency made simple

Research shows that sustained change is the key to success. The Smart Supplement is easy to remember, easy to take, and our monthly subscription means that you never run out. Convenient and flexible, so it works for you.
