Live well, age well: what really helps you stay healthy for longer
The steps with the strongest evidence for a longer, healthier life are everyday habits: stay active and strong, sleep well, don't smoke, and keep your weight, blood pressure, blood sugar and cholesterol in a healthy range. Peptides and NAD+ get a lot of attention, but none has been shown in human trials to help people live longer. A physician can help you focus on what matters most for you.

Live well, age well
"Aayu" is a Sanskrit word that means "to live" and "to age." We chose it because both matter. You want more years, and you want them to feel good: strong enough to carry the groceries, sharp enough to enjoy your work, with energy left for the people you love.
The good news is that the steps with the strongest evidence are things you can work on this month, with the right help.
What has the strongest evidence
- Move most days, and lift. Aim for at least 150 minutes a week of moderate activity, plus strength work on two or more days. That's the federal guideline.
- Protect your muscle. Muscle and strength fall with age, and some muscle is lost along with fat during weight loss. Strength training and enough protein help you keep them.
- Sleep at least seven hours. Loud snoring or daytime sleepiness can be a sign of sleep apnea, which is common and treatable.
- Know your numbers. High blood pressure, blood sugar and LDL cholesterol each raise the risk of heart attack, stroke and kidney disease, and bringing them down lowers it.
- Don't smoke. Quitting at any age lowers the risk of heart disease, stroke, lung disease and cancer.
- Keep up with screening and vaccines. What you need depends on your age, sex and history.
Where weight fits
Weight touches almost every item on that list. Extra weight raises the risk of type 2 diabetes, heart disease, sleep apnea and joint problems, and losing some of it can improve blood pressure, blood sugar and sleep apnea. It's also hard to do alone, which is why it's where our physicians focus.

Where peptides, NAD+ and supplements fit
You've probably seen peptides, NAD+ drips and supplements marketed for aging. Some have interesting lab and animal results, and it's fair to be curious. So far, none has been shown in human trials to help people live longer or stay healthier. Our peptide guide grades the evidence for each one, so you can see what's promising and what's proven.

Where Aayu Well stands
We don't offer a separate longevity or peptide program right now. What we do every day is the care with the strongest evidence for aging well: weight, metabolic health, mood and sleep, with a physician who takes the time to listen.
Questions people ask
Can an Aayu Well physician help me age well?
Yes. Our physicians focus on the parts of healthy aging with the strongest evidence: weight, blood sugar, blood pressure, muscle, sleep and mood. Bring your questions about peptides or supplements too, and you'll get a straight answer.
What is longevity medicine?
It usually means care aimed at staying healthy for longer, not just treating illness. The parts with solid evidence look a lot like good preventive care: your risk factors, screening, fitness and muscle.
Is there a reliable test for biological age?
Biological age tests, such as epigenetic clocks, are still research tools. Results differ from one test to the next, and they haven't been shown to guide treatment yet.
Do NAD+ drips or peptides slow aging?
Not that anyone has shown in people yet. Our peptide guide grades the evidence for each one, so you can see what's promising and what's proven.
