The benefits

Live bacteria that go further.

SPB — Benefits
Microbial diversity

A third-party human (in vivo) study showed that our active bacteria increases microbial diversity in the colon, balancing the gut microbiome.

Immune health

Our probiotic blend includes zinc, which contributes to the protection of cells from oxidative stress and the normal function of the immune system.

Skin, hair, and nails

The zinc in the Smart Probiotic contributes to the maintenance of normal hair, skin, and nails.

One capsule a day

All seven strains, along with zinc, are in every capsule.

At any time

We generally suggest taking it in the morning, but find a time that fits your schedule.

With or without food

No need to take anything else alongside your Smart Probiotic, unless you want to.

No need to refrigerate

Keep it in a cool, dark place.

3 reasons you’ll love it

  1. It’s rooted in science.

    Our formula, made up of seven strains in optimal amounts, is informed by 380+ studies.

  2. It’s proven to work.

    Third-party testing shows that it delivers 50x more alive and active bacteria than alternative tested formats.

  3. It's made and trusted by experts.

    It's developed by leading scientists and dietitians and loved by health professionals.

SPB – Pill exploding

Designed to survive

Most probiotics don’t work—the bacteria die before they reach the gut.

But our delayed-release technology and proprietary protective matrix guarantee the majority of our 20bn CFUs reach your colon, where they can have an impact.

What other health practitioners say

"Having worked in research, Heights' approach to supplements is the only one that can ever make sense—building on a body of evidence is the only acceptable approach, diametrically opposed to an otherwise rather unregulated market."
Dr Stephanie Potreck, MD, DD, RNutr (Sports)

"I'm a health-conscious, busy nurse who appreciates science backed medicine and supplements, so this was a no brainer after doing my research. I've noticed better sleep, clearer mind and I'm able to switch off after a long day."
Amun Abdullahi, Nurse
Community
"My sleep has improved ten fold. I'm asleep by 9.30pm and awake at 5am, fresh. I'm back training 5 times a week and my energy levels are the best they've been since my early 20s. I recommend this to all of my clients experiencing similar symptoms."
Joe Sharp, Physiotherapist
Community
"I couldn't be happier with Heights' supplements. They've exceeded my expectations, making a significant difference and becoming my top choice for recommending a comprehensive supplement to support a balanced diet."
Resma Patel, Consultant Dietitian & Nutritionist
Community
"As a doctor I was sceptical, but after three months I can definitely feel the benefit. Better nights sleep and improved mood for sure. Keep taking the tablets!"
