Timeline is one of the most research-backed brands in the longevity space, with human trials on its Mitopure ingredient and NSF Certified for Sport softgels. It is expensive and the benefits are gradual, but for buyers who want evidence over hype, it is a standout.
What we like
- Single, well-defined ingredient with multiple randomized, placebo-controlled human trials
- Consistent 500 mg daily dose across softgels, gummies and powder
- NSF Certified for Sport and Clean Label Certified softgels; vegan formulas
- Sugar-free gummy option sweetened with a stevia-derived ingredient
- 30-day money-back guarantee to test a first month
Keep in mind
- Costs about $99 for a one-month supply
- Effects are gradual; the brand suggests at least four months of use
- Research does not support every broad 'longevity' claim
- Full skincare routine adds significant extra cost
Timeline was created by Amazentis, a Swiss life-science company that has spent nearly two decades studying Urolithin A, a compound the gut produces from polyphenols in foods such as pomegranates, walnuts and berries. The catch is that many people do not produce much Urolithin A on their own. Timeline's answer is Mitopure, a highly purified form delivered in a consistent daily dose.
The brand focuses on mitochondria, the energy-producing parts of cells, and on a process called mitophagy, in which worn-out mitochondria are recycled. We looked at what Timeline sells, how strong the research is, what it costs, and who is most likely to benefit.
Why Urolithin A, and why Mitopure
As we age, mitochondrial recycling slows down, and damaged mitochondria can build up in tissues such as muscle. Urolithin A has been shown in research to stimulate mitophagy. Because gut bacteria vary so much from person to person, eating pomegranate or nuts does not reliably give everyone meaningful amounts. Timeline cites its own NOURISH study, which reported at least six times higher Urolithin A blood levels over 24 hours with Mitopure than with eight ounces of pomegranate juice.
Timeline developed Mitopure in collaboration with researchers at EPFL, the Swiss Federal Institute of Technology in Lausanne, and says the ingredient has received a favorable FDA GRAS review.
What the research shows
This is where Timeline is stronger than most longevity brands. It points to randomized, double-blind, placebo-controlled human trials, including:
- a study published in Cell Reports Medicine, which the brand says showed a 39% improvement in a marker of mitochondrial renewal after 16 weeks compared with placebo;
- a trial looking at gene expression related to mitochondrial function;
- a trial in overweight adults aged 40 to 65 that measured hamstring muscle strength.
The brand says there are more than 25 human clinical trials on Mitopure. Some caution is still fair: the company funds much of this research, effect sizes are modest, and studies mainly measure muscle and cellular markers rather than long-term outcomes such as lifespan or disease. Mitopure is best thought of as support for muscle and cellular health, not a way to stop aging.

Choosing a format
Every supplement format delivers the same 500 mg daily dose of Mitopure, so the choice comes down to preference:
- Softgels: two vegan softgels a day with no noticeable taste. They carry NSF Certified for Sport and Clean Label certification, which makes them the best choice for athletes in tested sport.
- Gummies: two strawberry-flavored, sugar-free gummies a day, sweetened with Reb M, a stevia-derived sweetener. They are vegan, non-GMO, gluten-free and free of the big eight allergens. The brand's most popular format.
- Powder: single-serve sachets you stir into yogurt, smoothies or other food.
If you are unsure, softgels are the simplest and most certified option; gummies are best if you dislike swallowing pills.
Timeline skincare
Timeline also applies Mitopure to the skin. Its topical range includes a Gentle Cleanser, a Resurfacing Exfoliator for limited weekly use, a Firming Serum that combines Mitopure with peptides, niacinamide and humectants, a lighter Dewy Cream, a richer Barrier Cream for dry or compromised skin, and an Eye Cream. Bundles such as the Inside-Out Starter Set pair supplements with skincare.
The serum is the core product if you only buy one. Everyone else can skip the full routine: a good sunscreen and a gentle moisturizer remain the most important anti-aging steps.
Pricing and how to buy
Timeline is premium. At the time of our research, a one-month supply of Mitopure softgels or gummies was listed at about $99 as a one-time purchase. Subscriptions are offered on some products and can reduce the cost and keep you supplied, but check the delivery interval and renewal terms before you commit.
Each supplement is covered by a 30-day money-back guarantee. Because Timeline recommends taking Mitopure for at least four months to judge the effects, think of the guarantee as protection against disliking the format or tolerating it poorly, rather than a full test of results. Review sites regularly publish first-order discount codes.
Who should consider Timeline
Timeline makes most sense for adults in midlife and beyond who are already doing the fundamentals, such as strength training, eating enough protein and sleeping well, and who want an evidence-led add-on aimed at muscle health. Endurance athletes and people focused on recovery may also be interested in the research on muscle performance.
It is less suitable for budget shoppers, younger adults without a specific reason, and anyone looking for a quick energy boost. Mitopure will not replace exercise, and it works best alongside it.
How to run a fair trial
If you decide to try Mitopure, set yourself up to judge it honestly. Before you start, note a few simple baselines you can repeat: how many push-ups or bodyweight squats you can do, your time on a familiar walk or run, or the weights you use for a regular lift. Take your daily dose at the same time each day, keep your training and diet roughly steady, and recheck those numbers at around three and four months. If you see no meaningful difference by then, it is reasonable to stop and redirect the money toward coaching, better food or other basics that have stronger general evidence.
Our verdict
Timeline is one of the few longevity brands whose core claims rest on published human trials, and its certification and labeling are excellent. The price is the main barrier. If it fits your budget, start with softgels or gummies, commit to about four months, and judge it by measurable changes such as strength or endurance. For comparison, fatty15 and partiQlar approach healthy aging through different nutrients.
