Bangkok's longevity clinics offer everything from blood tests and exercise plans to drips, hyperbaric oxygen and cell-based injections. The longevity medicine evidence behind these options varies enormously. Some interventions have been tested in hundreds of thousands of people over decades; others rest on mouse studies, small pilot trials or a clinic's own testimonials.

This guide sorts common longevity interventions into three tiers: well supported, promising but unproven, and experimental or higher-risk. It also explains how to read a clinic's "study" claim and what to ask your doctor. For an overview of how longevity services work in the city, see our longevity services guide.
Well-supported basics (exercise, sleep, BP, lipids)
The interventions with the strongest evidence for a longer, healthier life are not glamorous. They are the foundations of preventive medicine, and they are where a good longevity doctor should start.
Physical activity
Regular activity is linked with lower risk of heart disease, type 2 diabetes, several cancers and early death across a very large body of research. The World Health Organization recommends adults get at least 150 minutes of moderate or 75 minutes of vigorous aerobic activity a week, plus muscle-strengthening on two or more days. Strength and fitness both decline with age, and both can be trained at almost any age.
Blood pressure control
High blood pressure is one of the biggest modifiable risk factors for stroke and heart disease. A large analysis of 123 trials with more than 600,000 participants found that every 10 mm Hg reduction in systolic blood pressure cut major cardiovascular events by about 20% and all-cause deaths by about 13%. Lifestyle changes help, and medication is used when needed.
Lipids
Lowering LDL cholesterol in people at elevated risk is backed by decades of trials. The Cholesterol Treatment Trialists' Collaboration reports that statins reduce heart attacks, strokes and revascularisation procedures by roughly a fifth for each 1 mmol/L drop in LDL. Whether you need treatment depends on your overall risk, which your doctor should calculate.
Sleep, smoking and weight
Not smoking, moderate or no alcohol, a healthy body weight and enough sleep all have consistent evidence for reducing disease risk. Sleep is also central to day-to-day recovery; our guide to sleep and recovery covers practical habits.
The honest takeaway: if a clinic skips these basics and goes straight to drips or injections, it has its priorities upside down.
Promising but unproven
This tier includes interventions with a plausible biological rationale and some early human data, but no convincing evidence that they extend healthy lifespan in people.
| Intervention | What is known | Main gaps |
|---|---|---|
| NAD+ precursors (NMN, NR) | Raise NAD+ levels in blood and tissues; generally well tolerated in short trials | Unclear whether this improves function or health; small, short studies |
| IV NAD+ | Widely marketed in Bangkok | Very little controlled human data on benefits |
| Metformin for ageing | Diabetes drug with strong safety record; animal and observational data | The TAME trial designed to test it in healthy older adults has not launched |
| Rapamycin and similar drugs | Extends lifespan in some animal models | Limited human data; immune and metabolic side effects possible |
| Hyperbaric oxygen (HBOT) | Approved uses exist for specific medical conditions | Longevity claims rely on small studies with surrogate markers |
| Biological age tests | Research tools that correlate with health outcomes | Results vary by test; unclear how to act on them |
A 2023 review of NAD+-boosting supplements in humans concluded that these compounds can raise NAD+ and appear safe in the short term, but that evidence for improved physiological function is unclear. Our article on whether NAD+ IV therapy works looks at the drip versions in detail, and our review of HBOT longevity claims does the same for hyperbaric oxygen.
Metformin is a useful example of how long proof takes. The Targeting Aging with Metformin trial is designed to enrol more than 3,000 older adults over six years, but according to its organisers it still needs funding and has not started. Until trials like this report, "anti-ageing" use of any drug remains a hypothesis.
Experimental and higher-risk (stem cells, exosomes)
Cell-based and "regenerative" treatments sit in a different category. They are often expensive, involve injections or infusions of biological material, and carry real risks, including infection and reactions to contaminated products.
In Thailand, stem cell treatment in medical facilities is restricted. A 2024 report in The Nation, citing Ministry of Public Health standards, said permitted uses centre on haematopoietic stem cell transplantation for specified blood disorders, performed at approved institutions, and that injections advertised for other purposes are illegal. Rules can change and clinical research may operate under separate approvals, so check the current position with the Medical Council of Thailand or the Ministry of Public Health.
Exosomes, the tiny particles released by cells, are sometimes sold as a cell-free alternative. The US Food and Drug Administration states that no exosome products are approved, and that the only approved stem cell products are cord-blood-derived cells for blood-production disorders. It specifically warns that none are approved for orthopaedic, neurological, cardiovascular conditions, chronic pain or fatigue.
If you are offered stem cell therapy in Bangkok for ageing, joint pain or general vitality, treat it as a serious red flag rather than an advanced option.
How to read a clinic's "study" claim
Clinics often say a treatment is "clinically proven" or "backed by research". These questions help you judge what that means.
- Was it in humans? Many longevity claims come from mice, worms or cells in a dish.
- Was there a control group? Before-and-after results without comparison can reflect placebo, natural change or selective reporting.
- How many people, for how long? A 12-person, 8-week study cannot show effects on lifespan.
- What was measured? A change in a blood marker or "biological age" score is not the same as fewer heart attacks or longer life.
- Who paid for it? Industry funding does not invalidate a study, but independent replication matters.
- Is it published? A peer-reviewed paper is more reliable than a brochure or press release.
- Does it match the product? A trial of an oral supplement does not prove an IV version works.
Common phrases to treat with caution
- "Reverses ageing" or "turns back your biological clock"
- "Detoxifies" or "cleanses at the cellular level"
- "No side effects"
- "Used by celebrities and athletes"
- Package discounts that require you to pay for many sessions upfront
Questions to ask your doctor
A good longevity consultation should feel like careful preventive medicine, not a sales meeting. Bring these questions to the doctor, whether at a hospital centre or a clinic you find through our longevity directory.
- What are my main health risks, based on my history, family history and tests?
- What is my blood pressure, LDL cholesterol and blood sugar status, and do they need action?
- Which of your recommendations have strong evidence in humans, and which are experimental?
- What are the risks and side effects of each treatment you suggest?
- How will we measure whether it is working, and when will we stop if it is not?
- Can you give me a written plan I can share with my doctor at home?
- What is the full cost, and can I pay per session rather than upfront?
See a doctor promptly, rather than a wellness clinic, if you have chest pain, breathlessness, fainting, unexplained weight loss or other new symptoms.
Frequently asked questions
Are stem cell treatments legal in Thailand?
Regulation is restrictive. Recent reporting citing Thai health authorities says stem cell treatment is permitted mainly for specified blood disorders at approved institutions, and that clinics advertising injections for other uses are acting illegally. Rules can change, so confirm the current position with the Medical Council of Thailand or Ministry of Public Health before considering any treatment.
Is NAD+ proven to slow ageing?
No. NAD+ precursors raise NAD+ levels in the body and seem well tolerated in short trials, but there is no good evidence that they slow ageing or extend lifespan in humans. Evidence for IV NAD+ is even thinner.
Does anti-ageing medicine work at all?
The parts that overlap with conventional preventive medicine work well: exercise, blood pressure and lipid control, not smoking and good sleep. The parts sold as unique anti-ageing treatments are mostly unproven.
Are biological age tests worth doing?
They can be interesting, but different tests give different results and there is limited guidance on how to act on them. Standard markers like blood pressure, lipids and blood sugar remain more useful for decisions.
