HBOT — Hyperbaric Oxygen Therapy — places patients in a pressurized chamber breathing concentrated oxygen, dramatically increasing the amount of oxygen dissolved directly into the bloodstream and tissue.

That surplus of oxygen supports cellular repair, reduces inflammation, and can accelerate healing in tissue that's been slow to recover — from injury, chronic inflammation, or reduced blood flow.

It's not a cure-all. It's a tool we use when the data points to oxygen delivery as the limiting factor in recovery.

Most panels test what insurance will cover. Ours tests what actually matters.

The Comprehensive Diagnostics Package covers full hormone panels, inflammatory markers, micronutrient status, metabolic function, and cardiovascular risk markers most routine bloodwork skips entirely.

It's the foundation every protocol at Extension Health is built from — because you can't fix what you haven't measured.

The transition through perimenopause into postmenopause isn't a single event — it's a years-long shift, and treating it as one moment means missing most of the window to intervene.

Our protocol tracks hormone levels (estrogen, progesterone, FSH) across the transition, not just at a single visit, adjusting treatment as the pattern changes: hormone optimization, bone density monitoring, and symptom-targeted support at each stage.

The right protocol six months ago isn't necessarily the right one now. That's the point of tracking it.

Movement, performance, recovery. And the science behind it.

We joined Fleet Feet NYC and Marni on the Move for a morning of Yoga for Runners, followed by a live Marni on the Move podcast conversation featuring our very own ValerieSheehan, FNP, diving into peptides, performance, recovery, and how a more personalized approach can support the way you train.

Longevity isn’t just about living longer, it’s about moving, performing, and feeling your best along the way.

Thank you to Fleet Feet and Marni Salup for joining us in bringing the community together.

You train hard. But is it actually working?

For so many people, fitness is measured by how a workout feels, what a wearable estimates, or what the scale says. Together, Extension Health and NRTHRN Strong are building something more measurable.

Start with the data. Establish your baseline. Train with intention. Then come back and see what changed.

Our new partnership pairs VO₂ Max testing and advanced diagnostics at Extension Health with NRTHRN Strong’s performance-driven approach to strength, cardio, and mobility, connecting what’s happening inside your body with the work you’re putting in.

Extension Health × NRTHRN Strong was featured in F**t Insider, and we’re excited to bring a more data-driven approach to performance and longevity to New York City.

That "wait, when did this happen?" moment in the elevator mirror isn't about the lighting. It's your skin telling you something shifted, usually long before you noticed.⁠
⁠
Collagen production starts slowing down earlier than most people think, often in your late 20s. It's quiet, not dramatic. Which is exactly why most people wait until it's obvious to do anything about it.⁠
⁠
We work with patients before that point, using their own biology to help skin keep doing what it's already built to do. Not covering anything up. Just supporting it.⁠

Introducing our partnership with .

At Extension Health, we use advanced diagnostics to give you a deeper understanding of your health, performance, and longevity.

Our VO₂ Max Diagnostics is one of the clearest measures of your aerobic fitness, and an important marker of cardiovascular health and longevity.

That’s where training meets data.

The NRTHRN Trainer is built on the same demands as cross-country skiing, one of the most complete endurance sports there is. Upper body and lower body working together, challenging your cardiovascular system while building strength, endurance, and mobility at the same time.

Extension Health and NRTHRN Strong are bringing data and performance training together by combining clinical insights with intentional training to help you understand your baseline, train smarter, and measure meaningful progress over time.

Because better performance starts with better data.

Know your baseline. Train with purpose. Measure your progress.

"Cognitive enhancement" conjures images of unregulated nootropics. What we actually prescribe looks nothing like that.

Every protocol starts with diagnostics: inflammatory markers, hormone panels, and metabolic testing, since cognitive decline is frequently downstream of a system-wide issue, not a standalone problem.

From there: targeted peptide therapy for neuroinflammation, hormone optimization when that's the driver, and IV nutrient support where deficiencies show up on labs.

Nothing off a supplement shelf. Everything backed by your own bloodwork.

An oral formulation is showing results that, in early data, approach what we've seen from injectable versions of the same class of drug — a meaningful shift if it holds up.

The appeal is obvious: no needles, easier adherence, and a lower barrier to staying consistent with treatment.

The caveat is just as important: "approaches injectable results" isn't "matches them," and long-term, head-to-head data is still limited. This is a development worth watching, not yet a reason to switch.
