Julie Gibson Clark became a familiar name in longevity circles for doing something refreshingly ordinary: spending relatively little money. 

The former structural engineer turned recruiter says she spent more than a year ranked second on the Rejuvenation Olympics leaderboard while keeping her biohacking budget below $150 per month (1).

Her reported DunedinPACE score of around 0.65 drew the most attention. That number suggests her measured pace of biological aging was slower than one biological year for each chronological year. It is an interesting biomarker result, but it does not mean she has stopped aging or will live a set number of extra years.

Key Takeaways:

• Julie Gibson Clark formerly held the #2 position on the Rejuvenation Olympics leaderboard.

• Her reported DunedinPACE result was around 0.65, suggesting a slower measured pace of biological aging.

• Her routine centers on exercise, vegetables, protein, sauna, meditation, sleep, and supplements.

• Her results cannot tell us which habit or supplement caused the change.

Who Is Julie Gibson Clark?

Julie Gibson Clark is a Phoenix-based longevity enthusiast and single mother who previously worked as a structural engineer before becoming a recruiter.

Her approach gained attention partly because it contrasted sharply with expensive longevity programs. Rather than spending hundreds of thousands of dollars, she built her routine around exercise, food, sauna, stress management, and a smaller supplement stack (1).

That distinction matters. Much of her protocol resembles normal health habits taken very seriously, rather than futuristic anti-aging medicine.

Why Did Julie Gibson Clark Become Famous?

Her DunedinPACE testing put her on the longevity map.

DunedinPACE is a DNA methylation test designed to estimate the pace of biological aging. Researchers developed it using changes in 19 measures of organ-system health tracked across roughly two decades. In validation datasets, faster DunedinPACE scores were associated with greater morbidity, disability, and mortality risk (2).

The scale centers around 1.0, representing roughly one biological year of aging for every chronological year.

Julie has reported scores around 0.65 to 0.66. Put simply, her test suggested she was aging at around two-thirds of the reference pace.

There is an important catch. A score of 0.65 does not prove someone will live 35% longer. DunedinPACE is a biomarker used to estimate aging rate, not a countdown clock for lifespan.

What Is Julie Gibson Clark's Longevity Routine?

There is no single magic trick in her routine. It is a collection of habits repeated day after day.

Exercise

Julie mixes strength training with cardiovascular work, including Norwegian 4x4 interval sessions aimed at improving VO2 max. She also walks, stretches, and commonly follows workouts with 20 to 30 minutes in a sauna (3).

That emphasis on cardiovascular fitness has good observational support. A study following 4,137 adults for an average of 24.2 years found that each one-MET increase in cardiorespiratory fitness was associated with an 11.6% lower risk of death from any cause (4).

That does not prove Julie's workouts caused her DunedinPACE result, but cardiovascular fitness is one of the more evidence-backed parts of her routine.

Diet and Fasting

Her food habits lean heavily toward vegetables and protein.

Julie says she aims for more than 100 grams of protein per day based on her lean body mass. Her diet also includes leafy greens, vegetables, fermented foods, protein drinks, eggs, yogurt, meat, and home-cooked meals (3).

She has also discussed following a fasting-mimicking diet.

Research here is interesting but still developing. A 2024 analysis found that three fasting-mimicking diet cycles were associated with lower insulin resistance, reduced liver fat, and a median biological-age reduction of about 2.5 years, independent of weight loss (5).

That finding does not mean everyone following the diet will become 2.5 years biologically younger. It does give researchers a reason to keep studying the approach.

Sleep, Sauna, and Stress

Meditation, morning light, sleep, and sauna also form part of Julie's routine.

These habits can be easy to overlook because supplements get more attention online. Yet her routine is built much more around daily behavior than pills and powders.

What Supplements Does Julie Gibson Clark Take?

Her public supplement protocol has changed over time, so any list should be treated as a snapshot rather than a permanent prescription.

At the time of writing, she publicly lists supplements including (6):

She also lists prescription hormone therapy as part of her personal protocol. That is very different from an over-the-counter supplement and requires medical supervision.

One detail worth noticing is that Julie's stack contains both NR and, at times, NMN. Both compounds are NAD+ precursors, but they should not be treated as interchangeable proof that raising NAD+ slows human aging. Longevity outcomes remain an active research area.

Does Julie Gibson Clark's Anti-Aging Routine Really Work?

Her test results show something interesting happened to a biomarker. They cannot tell us exactly why.

Julie exercises, eats carefully, monitors protein intake, uses a sauna, meditates, takes supplements, experiments with fasting, and pays close attention to sleep. Changing that many variables at once makes it impossible to credit one intervention.

This is where many discussions of her story get ahead of the evidence.

Exercise and cardiorespiratory fitness have much stronger human data behind them than claims that a particular longevity supplement can slow aging. Fasting-mimicking diets have promising human findings, while biological-age testing itself remains a developing field.

Her experience is best viewed as a personal longevity experiment, not a clinical trial.

Final Words

Julie Gibson Clark's story is interesting because there is no single flashy trick behind it. Her routine comes back to the basics again and again: exercise, nutritious food, enough protein, sleep, stress management, sauna, and consistency.

Her DunedinPACE score adds an intriguing layer, but it should stay in context. A slower pace-of-aging biomarker does not prove that one supplement reversed aging or that she will live a set number of extra years.

At Omre, we see supplements as one part of a much bigger healthy-aging routine. Our NMN + Resveratrol formula is designed to support NAD+ pathways and cellular health alongside habits such as regular movement, good nutrition, and quality sleep. It is not a replacement for the basics, but it can fit naturally around them.

FAQs

How old is Julie Gibson Clark?

Julie Gibson Clark has publicly discussed her longevity journey as a woman in her 50s. Her exact age can change across older interviews and profiles, so current first-party information is the better reference.

What is Julie Gibson Clark's biological age?

Julie is better known for her pace-of-aging score than a single biological-age number. Her reported DunedinPACE score has been around 0.65 to 0.66.

What does a DunedinPACE score of 0.65 mean?

DunedinPACE uses 1.0 as a reference pace. A score near 0.65 suggests a measured pace of biological aging below that reference level. It does not mean a person will live 35% longer.

What supplements does Julie Gibson Clark take?

Her current public list includes NR or NMN, omega-3s, vitamin D3/K2, magnesium, B vitamins, NOVOS Core, moringa, chlorella, and maca, among other products (6).

How did Julie Gibson Clark slow her biological aging?

There is no way to identify one cause. Her routine combines exercise, diet, sleep, sauna, meditation, fasting strategies, and supplements, so her personal results cannot isolate the effect of any single intervention.
