Longevity & Healthy AgingLongevity & Healthy Aging

Don't just measure your health. Have a team help you improve it.

Living longer is one thing. Staying healthy, strong, and active throughout those years is what really matters.

Healthspan Year is designed to help you build better health over time.

Your clinician and wellness coach work together to understand your body, identify the areas of your health that need the most attention, and help you make meaningful changes to your nutrition, exercise, sleep, and daily habits.

Through ongoing testing, personalized guidance, and accountability, we help you implement your plan, track progress, and adjust it as we discover new opportunities for improvement.

The goal is to improve your overall health and address modifiable risk factors, because healthier habits and better management of those risk factors can reduce the risk of certain chronic diseases and support more healthy, active years.

What makes HFW different:

  • Discover: Identify the areas of your health that need attention.
  • Improve: Work with your clinician and wellness coach to build healthier habits.
  • Implement: Get support turning recommendations into consistent action.
  • Monitor: Track changes and adjust your plan throughout the year.

The HFW difference

Your physical asks if you are sick. We ask how well you are aging.

A normal checkup can miss what is behind low energy, poor sleep or stubborn weight. Here is what changes when your care runs on data.

Google review

I found out a few of my systems were aging faster than they should be, uncovered some gut issues I’m now working on… The 90-minute review with the doctor was honestly probably the best experience I’ve ever had with a doctor.

Google review

Heal From Within builds protocols, including peptides, supplements, diet and lifestyle factors which are based on testing… Would highly recommend to anyone looking to use peptides the right way, or age healthier in general!

Joe Baierwalter

HFW was able to help me with back pain and stiffness that had been chronic for years… They were very professional and gave me a targeted approach incorporating peptides.

FAQ

Quick answers.

What happens on the free call?

You talk through your goals and history with an advanced care clinician and leave with a clear next step, whether or not you continue with us. Bring recent labs and your clinician will review them for free. When your labs support it, some therapies, like peptides, can be prescribed on that call.

Where do I start if I'm not sure what I need?

Book the free call. Your clinician recommends a starting point based on your goals. For many people that is the 30-Day Health Deep Dive: your biological age, 180 markers across 11 organs and systems, a results review and a priority plan.

Can I use bloodwork I already have?

If you've had bloodwork in the last 6 months, bring it to your free call. For GLP, Recovery and individual peptide protocols, your clinician can often start from it and order only what's missing. Any additional testing is billed by the lab, and insurance may cover it.

How much does it cost?

Programs start at $199 a month, and every price is on our Programs page. Your clinician reviews pricing with you before you commit to anything.

Do you take insurance?

We're self-pay and don't bill insurance, which keeps care decisions between you and your clinician. HSA and FSA cards are accepted.

Do I have to come in?

No. Most patients are seen by secure video, because decisions come from your data. Testing is done at home or at a lab near you.

Who is HFW for?

People who want to feel and perform better now and stay independent longer, whether something feels off or you already feel good and want to stay ahead.
