The newest weight-loss injection available in the UK is tirzepatide, sold under the brand name Mounjaro.

Tirzepatide was approved in the UK for weight loss in November 2023 after it was approved for people living with type 2 diabetes in September 2023.

Tirzepatide’s well-known brand name is Mounjaro, and it’s currently available in the U.S. for type 2 diabetes.

Mounjaro became available in the UK in February 2024, and Second Nature launched our Mounjaro weight-loss programme.

Wegovy (semaglutide) is the other well-known weight-loss injection available in the UK and you can buy this online from Second Nature if you’re eligible for our Wegovy weight-loss programme.

What’s the best weight-loss injection in the UK?

Based on data from randomised controlled trials, tirzepatide appears to be the most effective weight-loss injection and tends to support more weight loss than Wegovy or Saxenda.

Tirzepatide supports average weight loss of around 25% after one year, compared to 17% on Wegovy and 7% on Saxenda.

However, everyone responds differently to medications, and it’ll be down to the individual and their healthcare team to determine the best course of treatment for them.

Can you get weight-loss injections on the NHS?

Wegovy and Saxenda are currently available via prescription on the NHS. However, these are only available alongside participation in a specialist weight management programme which has strict criteria for entry.

We recommend speaking with your GP or local healthcare team to discuss the weight management solutions available in your area.

Not a magic pill

Weight-loss injections are designed as additional tools for weight management interventions and shouldn’t be considered lifelong medications.

Instead, they should be used to help you kickstart your weight loss and healthy journey while you commit to living a healthier lifestyle.

Consider the use of antidepressants for people living with depression. They’re not designed to cure the condition. Instead, they’re designed to allow room for therapy to treat the condition’s underlying cause.

Mounjaro, and other weight loss injections, like Ozempic and Wegovy, are similar. They can allow you to make lifestyle changes to support long-term weight loss maintenance.

Mounjaro can help silence food-related thoughts and also give you a boost of confidence with more immediate weight-loss results.

This helps to buy you the time and headspace to understand why your body may have struggled to lose weight previously, and to build new long-term healthy habits.

The core focus of our medication programmes is to calm down the feeling of food noise, lower your cravings, and allow you to build healthier habits to keep the weight off for good.

The ultimate goal is to make losing weight feel second nature.

Second Nature’s medication-supported programmes

Second Nature has two medication-supported programmes: a Wegovy weight-loss programme and a Mounjaro weight-loss programme.

If you’ve made the decision to try Wegovy or Mounjaro (assuming you’re eligible), why should you choose Second Nature over other medication providers?

For peace of mind.

Second Nature has worked with the NHS for over 6 years providing weight-loss programmes across the UK.

Whilst our Wegovy and Mounjaro weight-loss programmes are private and not currently used by the NHS, we’ve built the programmes with a focus on scientific evidence, patient safety, and data security.

We hope that our 6+ years of working with the NHS and building a track record of effective weight-loss results will give you peace of mind to give us a try.
