Introducing The Eterna Journal
Longevity isn’t built in a single treatment or a single visit. It’s created through consistent, science-guided habits that help your body repair, regenerate, and thrive over time.
That’s why we’re introducing our new weekly newsletter, The Eterna Journal — a short, practical dose of evidence-based guidance designed to help you feel better, stay stronger, and age more powerfully.
Each week, we’ll spotlight a key longevity topic — beginning with one of the Four Pillars of Longevity. You’ll learn how these essential lifestyle foundations shape the way we age, and how we elevate them with regenerative and functional medicine tools.
We’re excited to guide you, week by week, on your longevity journey.
Age smarter. Feel better. Glow longer.
Warmly,
Irene Gladstein, MD, FACS

Longevity Pillar 1: Move
The Foundation of Vitality
Physical activity is the most powerful longevity intervention known. It protects the heart, strengthens the brain, lowers cancer risk, and preserves independence.
We pair movement with peptides, red light therapy, and recovery biologics so your body can rebuild stronger after every effort.
⸻
Longevity Pillar 2: Nourish
Feed Your Cells Wisely
Nutrition is more than calories. It’s cellular information. Whole, anti-inflammatory eating patterns support metabolism, brain health, and hormone balance.
We support this with functional nutraceuticals and metabolic peptides to personalize your nutritional foundation.
⸻
Longevity Pillar 3: Sleep
The Regeneration Cycle
Deep sleep is when your body repairs DNA, clears brain toxins, and resets hormones. Without it, aging accelerates.
We optimize sleep with circadian-balancing peptides, red light protocols, and nervous system support.
⸻
Longevity Pillar 4: Restore
Regulate Stress and Connection
Chronic stress ages the body from the inside out. A regulated nervous system protects the heart, brain, and immune system.
We integrate neuro-regulatory peptides, mitochondrial support, and guided recovery systems to restore resilience.
