Her Return
Built for female physiology: perimenopause and menopause, estrogen, progesterone and testosterone, bone density, and the ways stress and hormones meet in a woman's body.
Kristy King, MD
Return to Rhythm
Return to Rhythm is a structured 16-day program at Longevity Labs, The Shops at Mauna Lani, for women, men and couples facing burnout, depression, anxiety, hormonal change or a metabolic wake-up call. You work with one physician, Dr. Kristy King, from the first lab draw to the day you fly home. Starts are rolling.
Three tracks
His Return
Built for male physiology: testosterone evaluation and treatment when appropriate, with monitoring of red blood cell count and prostate health, fertility counseling for men who want children, and earlier attention to heart risk.
Return Together
For couples. Each partner has their own medical plan, chart and consent. You share coherence sessions where we measure both heart rhythms at once and watch them come into step, and you each have private time with Dr. King. Ketamine sessions are always individual.
Men and women are different physiologically, and each track is designed for that from the first lab draw.
Before you arrive
We begin with a 15-minute visit to see if Return to Rhythm fits. Screening questionnaires and a focused blood panel of about 20 markers, including hormones and cardiometabolic markers, are drawn near home before you travel. Your plan is drafted before day one.
What arrives after you book
A welcome letter and your schedule, your screening questionnaires, a lab requisition, your DNA, microbiome, DUTCH Plus, pace of aging and urine test kits, a continuous glucose monitor, and a guide to lodging near the clinic.
The four pillars
Bone
Estrogen protects bone. Hormone therapy lowers hip fracture risk, one of the best established findings in women's medicine. We review your bone health and your hormone options together.
Brain
Depression, alcohol, blood pressure, blood sugar, cholesterol, inactivity and isolation are among the 14 risk factors the 2024 Lancet Commission linked to dementia. Return to Rhythm works on many of them at once.
Heart
Lipids, glucose, insulin and blood pressure measured at the start and again before you leave, with a plan to carry forward.
Mind
Physician-administered ketamine sessions with Dr. King present, clinical hypnosis, breathwork and heart rate variability training, in a sequence built on published research.
Coming back into coherence
When your nervous system is steady, your heart rhythm rises and falls in a smooth, even wave. Stress, poor sleep, hormone shifts and constant screens break that rhythm up. We measure your coherence when you arrive and again before you leave, using your heart rhythm, your daily stress-hormone curve and your sleep. Then you practice coming back into it every day, with slow breathing and live heart rhythm feedback, hypnosis, and time away from your phone.
How we measure
| How we measure | |
|---|---|
| Before you arrive | A focused blood panel of about 20 markers: hormones, thyroid, glucose and insulin, lipids with ApoB, inflammation, iron, vitamin D and B12. Your DNA once, your gut microbiome, your pace of aging (DunedinPACE), your daily cortisol curve and hormone metabolites (DUTCH Plus), and a urine test for BPA and phthalates. A continuous glucose monitor arrives with your kit so we see your baseline before you travel. |
| During the program | A continuous glucose monitor and daily heart rhythm training. |
| At the end | Your mood scores, heart rhythm coherence, sleep, glucose, lipids and urine chemicals again. |
| At three months | A1c, ApoB, hormones and your pace of aging once more. |
A digital reset
Screens and social media now shape how we sleep, focus and feel, and the isolation of the pandemic years left many of us more alone than we realized. Before you arrive, we ask for your phone's own weekly screen-time report. During Return to Rhythm, mornings are phone-light, the hours after each ketamine session are screen-free, and every day includes real time with real people. You leave with your before-and-after numbers and a plan for home.
What the 16 days include
- Arrival and full intake
- A series of ketamine sessions spaced across the stay for people who are good candidates
- Clinical hypnosis before and after sessions
- Daily slow breathing and heart rate variability training
- Neurofeedback through a certified partner where it fits
- A hormone decision visit, with the option to leave with up to six months of hormone therapy when appropriate
- A metabolic reset with nutrition, movement and sleep
- Repeat measurements before you go home, and a written plan for your own doctor
What you eat
Three personalized whole-food, plant-based meals a day, delivered to where you stay. Rich in plant fats like avocado, olive oil, nuts and seeds, low in sugar, adjusted to your glucose readings, DNA and microbiome, with electrolytes and coconut water.
A sample day
- Tofu scramble with spinach, mushrooms, avocado and hemp seeds.
- Greens bowl with seitan or tempeh, pumpkin seeds and avocado miso dressing.
- Coconut cauliflower curry with tofu and macadamias.
- Walnuts, olives, flax crackers and chia pudding.
Protein for your stage of life
| Adult women | 0.8 minimum, and 1.0 to 1.2 grams per kilogram for metabolic health. |
| Perimenopause and after | 1.0 to 1.2, with 25 to 30 grams per meal. |
| 65 and older | 1.2 to 1.5. |
Women need more protein after menopause, not less. Your plan is set to your stage, your body and your kidneys. Your kit includes creatine, algal omega 3, vitamin D, B12 and magnesium.
Where you stay
You book your own lodging near the clinic on the Kohala Coast. Because you cannot drive after a ketamine session, we help you choose a place within walking or shuttle distance.

Is it right for me?
Some people are not candidates for ketamine, and heavy daily drinking needs medical care before travel. Your 15-minute visit is where we decide together.
