Boots vs Second Nature

Jump to: Quick comparison | Clinical evidence | Support and coaching | Aftercare and maintenance | Medication options | Pricing | Who should choose each | Frequently asked questions | Take home message

Second Nature and Boots both offer Mounjaro and Wegovy prescriptions alongside structured support, but they differ in clinical evidence, the type of professional support you receive, and how that support is delivered.

Second Nature is a specialist weight management provider that has worked with the NHS since 2017 and has published peer-reviewed research showing 19.1% average weight loss at 12 months with semaglutide and dietitian-led coaching.¹

Boots is the UK’s largest pharmacy-led retailer, offering weight-loss prescriptions through Boots Online Doctor alongside a coaching app (powered by Liva Healthcare), a 10-week structured programme, and a 12-month aftercare programme for patients who stop treatment.²

Both providers are regulated. Second Nature’s pharmacy partner is GPhC-registered, and Boots Digital Health is registered with the Care Quality Commission. This guide compares what each offers so you can decide which approach suits your needs.

This guide was written by Second Nature, so it naturally reflects our perspective, but we’ve aimed to present Boots’ strengths and limitations as fairly as possible.

Boots vs Second Nature: quick comparison

Clinical evidence and outcomes

Second Nature: published peer-reviewed research

Second Nature has published programme-specific outcomes in peer-reviewed journals. Our 2025 study in JMIR Formative Research examined 12-month outcomes for participants using semaglutide with our behavioural support programme and found¹:

• 19.1% average weight loss at 12 months for participants who maintained an active subscription
• 77.7% achieved at least 10% weight loss
• 61.5% achieved at least 15% weight loss
• 69% reported no side effects by month 12

Separately, an NHS-published evaluation in the BMJ found that Second Nature achieved substantially higher weight loss than four other providers in the National Diabetes Prevention Programme.³

These are completer analyses rather than intent-to-treat analyses, which means they reflect outcomes for people who remained engaged with the programme.

Boots: established clinical team, limited published outcomes

Boots’ weight-loss service is led by a named clinical team that includes GPs, pharmacists, and a BANT-registered nutritionist. Their clinical lead for weight loss, Dr Sam Wellappili, is a GP with training in nutritional therapy and lifestyle medicine.⁴

Boots reports that 90% of their weight-loss patients are happy with the service.⁴ However, they haven’t published programme-specific weight-loss outcomes in a peer-reviewed journal, so it’s not currently possible to directly compare clinical results between the two providers.

Their coaching partner, Liva Healthcare, works with the NHS on diabetes prevention and has its own evidence base for digital health coaching, though this is separate from the Boots weight-loss service.

Support and coaching compared

Second Nature

Second Nature pairs medication with a structured behaviour change programme developed by dietitians, psychologists, and behavioural scientists. The programme uses the COM-B model (capability, opportunity, motivation) and runs across four phases over 12 months or more.¹

Day-to-day support is provided by registered dietitians and nutritionists (HCPC or AfN registered), available five days a week via in-app messaging. You’re also placed in a small peer support group with others at a similar stage, which provides accountability and shared experience.

The programme covers nutrition (using a balanced plate model rather than calorie counting), physical activity, sleep, and the psychological aspects of eating behaviour, with daily educational content delivered through the app alongside coaching.

Boots Online Doctor

Boots offers support through several channels. Their primary coaching is delivered through the Boots Online Doctor Coach app, built in partnership with Liva Healthcare, a digital therapeutics company that also works with the NHS on diabetes prevention.⁵

Through Liva, you’re assigned a health coach who provides personalised advice via video consultations and in-app messaging. Coaches include qualified dietitians, nutritionists, and health coaches trained in behavioural psychology.⁵

Boots also offers a free, self-paced 10-week programme in their Tracker app, covering psychology, nutrition, sleep, metabolism, and motivation. Additional resources include a podcast (22 episodes covering topics from GLP-1 medications to cravings and self-sabotage), weekly live webinars, and exercise videos.⁴

For those who prefer face-to-face contact, Boots has piloted in-store consultations with Pharmacist Independent Prescribers at 17 stores, and free weigh-ins and pharmacy advice are available at over 1,500 stores nationwide.⁴

Key differences in approach

The main distinction is depth versus breadth. Second Nature’s model is built around sustained 1-to-1 coaching from registered dietitians within a structured multi-phase programme, with peer group support and published outcomes demonstrating its effectiveness.

Boots’ model offers more variety in how you access support — app coaching, self-paced learning, podcasts, webinars, in-store services — across a wider range of channels, backed by a trusted high-street brand and CQC registration.

Aftercare and weight maintenance

Research shows that around two-thirds of people regain weight within a year of stopping semaglutide without ongoing support.⁶ This makes aftercare one of the most important factors when choosing a provider.

Both providers have developed approaches to address this, though they differ in structure.

Second Nature

Transition support is built into the programme itself. The later phases of Second Nature’s programme focus on consolidating habits and preparing for life after medication.

If you and your prescriber agree to reduce or stop medication, your dietitian continues to support you through that transition within your existing programme.

Boots

In March 2026, Boots launched a free 12-month aftercare programme, which they describe as the first of its kind from an online healthcare provider in the UK.

It was developed in response to NICE guidance recommending at least 12 months of structured follow-up after stopping weight-loss treatment.²

The aftercare programme includes unlimited messaging with Boots Online Doctor clinicians, monthly emails with expert resources on nutrition and activity, access to webinars and podcasts, weight tracking through their app, and free in-store weigh-ins. It’s available to patients who used the Boots weight-loss service for at least six months before stopping treatment.²

Medication options and availability

Both providers prescribe Mounjaro, Orlistat, and Wegovy, including the newer 7.2 mg Wegovy dose approved by the MHRA in January 2026.⁷

Boots offers a wider range of medication options, including Nevolat (a generic version of liraglutide, taken as a daily injection).

Since Eli Lilly raised Mounjaro’s UK list prices in September 2025, both providers have highlighted Wegovy as a potentially more affordable alternative. Boots specifically reduced the price of Wegovy following the Mounjaro price increase.

Pricing

Pricing for weight-loss medications changes frequently, so check each provider’s website for the most current figures. As a general guide at the time of writing:

Second Nature charges an all-inclusive monthly fee covering medication, delivery, dietitian coaching, app access, and peer support. Wegovy ranges from approximately £99 to £249 per month, depending on dose. Mounjaro pricing is available on the Second Nature website.

Boots Online Doctor charges per medication pen, with support resources included at no extra cost. Wegovy ranges from approximately £95 (0.25 mg starting dose) to £209 (2.4 mg maintenance dose) per pen. The Liva coaching programme is an additional service.

When comparing prices, check what’s included: Second Nature bundles everything into one monthly fee, while Boots prices the medication and coaching separately.

Who should choose each option

Second Nature may suit you if:

• You want dietitian-led coaching integrated with your medication from day one
• Published, peer-reviewed clinical outcomes are important to you
• You’ve struggled to maintain weight loss in the past and want structured habit-change support
• You value peer support from others at a similar stage
• You prefer an all-inclusive monthly price with no separate costs

Boots may suit you if:

• You prefer the trust and convenience of a well-known high-street brand
• You’d like the option of face-to-face consultations or in-store weigh-ins
• You want access to a wider range of medications (including Nevolat and Orlistat)
• You’re interested in the free 12-month aftercare programme when you stop treatment
• You prefer a self-paced approach with a variety of support resources (podcast, webinars, app)

Frequently asked questions

Is Second Nature or Boots more effective for weight loss?

Second Nature has published peer-reviewed research showing 19.1% average weight loss at 12 months with semaglutide and behavioural support.¹

Boots has not published comparable programme-specific outcomes, so a direct comparison isn’t currently possible. Both providers prescribe the same medications, so the difference in results is likely due to the type and intensity of support provided alongside medication.

Does Boots offer dietitian support?

Boots’ coaching is delivered through a partnership with Liva Healthcare. Their coaching team includes dietitians, nutritionists, and health coaches trained in behavioural psychology.⁵

Boots also has a BANT-registered nutritionist and GPs on their in-house clinical team.⁴ Second Nature’s day-to-day coaching comes from HCPC-registered dietitians and AfN-registered nutritionists.

Can I get Wegovy 7.2mg from both providers?

Yes. Both Second Nature and Boots offer the 7.2 mg dose, which was approved by the MHRA in January 2026.⁷

This dose is for patients who have been stable on 2.4 mg for at least four weeks and need further weight loss. It’s currently administered as three separate 2.4 mg injections taken together.

What happens when I want to stop taking medication?

Both providers offer support for stopping treatment. Second Nature builds transition support into its programme phases, with your dietitian guiding you through the process.

Boots launched a free 12-month aftercare programme in March 2026, available to patients who had used its services for at least six months.² Research shows that structured follow-up after stopping GLP-1 medication significantly reduces weight regain.⁶

Is Boots cheaper than Second Nature?

It depends on what you’re comparing. Boots’ medication-only prices may be lower than Second Nature’s all-inclusive fees, but Second Nature bundles dietitian coaching, peer support, and programme access into its monthly price.

If you add Liva coaching to your Boots prescription, the total cost may be comparable. Check both providers’ websites for current pricing.

Does Boots offer in-person appointments?

Boots has piloted face-to-face weight-loss consultations with Pharmacist Independent Prescribers at 17 stores in the UK.⁴

Free weigh-ins and pharmacy advice are available at over 1,500 Boots stores. Second Nature is fully remote, which suits people who prefer not to visit a clinic or store.

Can I switch from Boots to Second Nature (or vice versa)?

Yes. You can switch providers, though you’ll need a new clinical assessment. If you’re already on a stable dose of Mounjaro or Wegovy, you won’t necessarily need to restart from the lowest dose. Both providers can guide you through the process.

Does Second Nature have NHS backing?

Second Nature has been commissioned by the NHS since 2017 and currently works with 43 ICBs and Health Boards across the UK.³

The private Mounjaro and Wegovy programmes are separate from the NHS-commissioned services, but they’re built on the same behavioural science and clinical infrastructure.

Boots’ weight-loss service is private-only, though their coaching partner, Liva Healthcare, works with the NHS separately on diabetes prevention programmes.

Are these services safe?

Both providers are regulated. Second Nature works with a GPhC-registered pharmacy partner for prescribing and dispensing. Boots Digital Health is registered with the Care Quality Commission.⁴

Both have clinical teams that review your medical history before prescribing and monitor your progress throughout treatment.

Which provider has better reviews?

Second Nature has a 4.5/5 Trustpilot rating from over 7,800 verified reviews. Boots reports that 90% of its weight-loss patients are satisfied with the service, though this is based on internal data rather than an independent review platform.⁴

Take home message

Second Nature and Boots both offer legitimate, regulated weight-loss services with Mounjaro and Wegovy. The right choice depends on what matters most to you.

Second Nature’s strength is its depth of clinical evidence and specialist focus. Published research shows 19.1% average weight loss at 12 months with semaglutide and dietitian-led support, and the programme is built on eight years of NHS-commissioned weight management experience.^1,3

Boots’ strength is the breadth and accessibility of its offering. A trusted high-street brand, CQC registration, multiple support channels (app coaching, podcasts, webinars, in-store services), a wider range of medication options, and a dedicated 12-month aftercare programme for patients who stop treatment.^2,4

Second Nature’s published research shows that semaglutide combined with dietitian-led coaching produced 19.1% weight loss at 12 months, compared to 13.7% with medication alone in clinical trials; a pattern consistent with wider evidence that behavioural support improves outcomes.¹
