What are common anti-aging treatments? Scientific evidence comparison of various interventions
Common treatments in anti-aging clinics can be broadly categorized into hormone assessment and supplementation, NAD+ precursors (NMN/NR) and intravenous nutrition, PRP prolotherapy, exosome therapy, chelation therapy, hyperbaric oxygen, and biological age-related tests (DNA methylation clocks, functional medicine, genetic and telomere testing). The level of scientific evidence varies greatly: PRP has stronger randomized controlled trial data for orthopedic indications; NAD+ precursor human trials are emerging; hyperbaric oxygen has small-scale RCTs; exosomes and some injections lack large-scale human studies. This page provides neutral information, does not claim efficacy, and does not constitute medical advice. All indications and risks should be evaluated by a qualified physician on an individual basis.
How to stratify scientific evidence for each treatment
Treatments labeled 'anti-aging' vary greatly in evidence strength. They can be roughly stratified for understanding (neutral summary, not endorsing any intervention):
- PRP: Multiple randomized controlled trials (RCTs) exist for orthopedic indications such as knee osteoarthritis and tendon injuries, but fewer RCTs for cosmetic/systemic anti-aging use.
- NAD+ precursors (NMN/NR): Several human trials have confirmed safety, but large-scale long-term benefits are still lacking.
- Hyperbaric oxygen: Small-scale RCTs exist; larger studies are needed for replication.
- Exosomes and chelation therapy for anti-aging: Limited large-scale human trial data.
- Hormone replacement: More long-term studies exist for specific indications, but use for anti-aging remains controversial.
What common treatments involve
The following is a neutral description of common procedures; suitability must be assessed by a physician:
- PRP prolotherapy: Autologous blood is drawn, centrifuged, and injected into specific areas to aid repair.
- NAD+/anti-aging IV: Intravenous supplementation of coenzymes or vitamins.
- Hormone replacement: e.g., menopausal HRT, testosterone, growth hormone; has FDA-approved specific indications.
- Exosomes, hyperbaric oxygen: Mostly research or adjunctive in nature.
Key points for evaluating treatments and clinics
Before considering any anti-aging treatment, it is recommended to verify each item and not rely solely on marketing:
- Level of scientific evidence and published data for the treatment.
- Whether the institution is legally registered and the physician's specialist qualifications.
- Whether risks, side effects, and alternatives are fully explained.
- If cell therapy, whether it is an approved item and institution under the Specific Management Regulation.
FAQ
How are the scientific evidence levels of various anti-aging treatments roughly classified?
Rough stratification based on current literature (neutral summary, this site does not endorse any intervention): ① PRP has multiple RCTs for orthopedic indications such as knee osteoarthritis and tendon injuries, representing moderate scientific evidence; fewer RCTs for cosmetic/systemic anti-aging use. ② NAD+ precursors (NMN/NR) have several human trials (NMN: Yoshino et al. 2021, Cell Metabolism; NR: multiple) confirming safety, but large-scale long-term studies are lacking. ③ Hyperbaric oxygen has a small-scale RCT by Efrati et al. 2020 (Aging journal). ④ Exosomes and chelation for anti-aging have limited large-scale human trial data. ⑤ Hormone supplementation has more long-term studies for specific indications (e.g., WHI study), but controversy remains for anti-aging use.
What is PRP prolotherapy? What are the differences between orthopedic and anti-aging uses?
PRP (platelet-rich plasma) is obtained by centrifuging autologous blood and then injected into specific sites to promote repair. In orthopedics (knee osteoarthritis, Achilles tendinitis, etc.), there are more RCTs supporting its use, making it the more established application area. Studies on 'cosmetic PRP' and 'PRP for hair growth' are increasing but smaller in scale. A single session costs approximately NT$15,000–35,000 (depending on site and dosage). Indications and outcomes vary by individual and require physician evaluation.
What are NAD+ and anti-aging IV drips?
NAD+ is a key coenzyme in cellular energy metabolism; its precursors NMN and NR can be converted in the body. In 2021, Yoshino et al. (Cell Metabolism) published a small-scale RCT of NMN showing increased skeletal muscle NAD+ metabolism. Common 'anti-aging IV drips' in Taiwanese clinics refer to intravenous supplementation of NAD+ or vitamins, costing several thousand to tens of thousands of NT$ per session. Large-scale long-term anti-aging benefits are still under investigation. It is recommended that a physician evaluate individual suitability; see our 'Regenerative Medicine' section for details.
What should be noted about hormone/growth hormone supplementation?
Hormone supplementation (e.g., postmenopausal estrogen HRT, testosterone, growth hormone HGH) has FDA-approved indications (e.g., menopausal symptoms, diagnosed growth hormone deficiency), but use for 'anti-aging' purposes remains controversial. After the 2002 US WHI study, the risk-benefit of estrogen use was reassessed. Growth hormone has common side effects such as fluid retention and blood glucose effects. Such treatments require comprehensive evaluation and regular monitoring; they should not be used without a diagnosis.
What are exosome therapy and chelation therapy? Is there evidence?
Exosomes are microvesicles secreted by cells. Animal and in vitro studies suggest they may be involved in intercellular communication and tissue repair, but large-scale RCTs for human anti-aging are lacking. In Taiwan, they are also regulated under regenerative medicine laws. Chelation therapy was originally for heavy metal poisoning. The 2013 TACT trial showed a modest benefit in post-myocardial infarction patients, but evidence for 'anti-aging' is insufficient. It should only be considered after thorough evaluation by a qualified medical institution and physician.
Is there evidence for hyperbaric oxygen anti-aging? How to evaluate a clinic?
Hyperbaric oxygen therapy (HBOT) in a small-scale RCT by Efrati et al. 2020 (Aging journal) showed increased telomere length and clearance of senescent cells, but the study had only dozens of participants and requires larger replication. When choosing, ensure the facility has a certified hyperbaric chamber (medical device approval), qualified operators, and emergency protocols, and that a physician evaluates indications.
