Quick answer: The most powerful natural anti-aging strategies are daily habits: strength training and aerobic exercise, deep sleep, a whole-food diet, time-restricted eating, stress care and mild hormetic stressors like sauna. Supplements such as NAD+ precursors, spermidine, collagen, astaxanthin and senolytic compounds are being studied, and they work best on top of those foundations.
Key takeaways
The most powerful natural anti-aging tools are daily habits such as strength training, deep sleep and a whole-food diet.
Time-restricted eating, stress care and mild stressors like sauna also support the biology of aging.
Supplements such as NAD+ precursors and spermidine are still being studied and work best on top of those foundations.
Daily habits that matter most
The habits that matter most are strength training plus aerobic and interval exercise, seven to nine hours of sleep in a dark room, and a whole-food, plant-rich diet with enough protein. A consistent overnight fasting window, sauna or cold exposure if appropriate, and strong social connections and stress care complete the picture.
Supplements being studied
NAD+ precursors (NMN, NR) support cellular energy (see NAD+), and spermidine has been studied for autophagy. Fisetin and quercetin have been studied as senolytics (see senolytics), and collagen with vitamin C supports skin and joints.
Astaxanthin is an antioxidant studied for skin, astragalus compounds have been studied for telomere support, and berberine supports AMPK and blood sugar.
Much of this research is early. Amounts should be individualized. My tiered options are described in longevity protocols, and the products I use are in my Fullscript dispensary.
Tracking your progress
Markers such as hs-CRP, fasting insulin, A1C and lipids reflect how you are aging metabolically. Epigenetic age and telomere tests are available but still evolving. Functional labs are optional. They can be helpful in more complex cases, and in my practice they are available only to patients working 1-on-1 with me.
Anti-aging and the biology of aging
Effective anti-aging strategies target the core processes of aging: mitochondrial dysfunction, inflammaging, senescent cells, deregulated nutrient sensing, disabled autophagy, telomere attrition and epigenetic changes. Habits can influence many of them at once, which is why they come first. Related: practicing longevity.
When to see a naturopathic doctor
It may be time to see a naturopathic doctor if you want an evidence-based healthy-aging plan, or if you are taking several longevity supplements and want to simplify. The same is true if you want to track biomarkers of aging, or if you take medications and want to check interactions.

Frequently asked questions
What is the most effective natural anti-aging strategy?
