Timeline Nutrition built its reputation around Mitopure, a proprietary form of Urolithin A developed with 18 years of research alongside the Swiss Federal Institute of Technology in Lausanne (EPFL). The brand backs its formulas with 25 human clinical trials and holds 80 patents protecting the ingredient, a rare depth of documentation for a supplement company. From gut-activated capsules to topical serums, Timeline Nutrition now applies the same molecule across both skincare and daily supplements, giving shoppers several ways to try the science firsthand.
Pros:
✅ Supports firmer, more resilient-looking skin over time
✅ Helps skin appear more even in tone and texture
✅ Fits easily into an existing nightly skincare routine
✅ Targets visible signs of cellular aging at the skin’s surface
This lightweight facial serum delivers Mitopure directly to the skin, pairing the Urolithin A molecule with a topical delivery system designed to support mitochondrial renewal at the cellular level. It suits anyone already using serums or actives who wants to layer in a longevity-focused ingredient rather than switch their whole routine. Early adopters describe the texture as "silky, not sticky" and note it absorbs quickly under moisturizer. Those new to active skincare may want to patch test first, since individual skin sensitivity can vary.
Highlights:
- Formulated with Mitopure, Timeline’s patented Urolithin A ingredient
- Lightweight, fast-absorbing serum texture
- Designed for nightly use on cleansed skin
- Backed by the same research platform as Timeline’s oral supplements
Pros:
✅ Leaves skin feeling smoother after regular use
✅ Helps refine the look of pores and rough texture –
✅ Preps skin so other products absorb more effectively
✅ Gentle enough for a consistent weekly routine
This resurfacing treatment combines exfoliating action with Mitopure to address surface texture while supporting the skin's deeper cellular processes. It works well for people who already exfoliate regularly and want a formula that goes beyond standard acids or scrubs. Reviewers describe results as "gradual but noticeable" after a few weeks of consistent use rather than an overnight transformation. Those with very reactive or compromised skin barriers should introduce it slowly or check with a dermatologist first.
Highlights:
- Contains Mitopure alongside resurfacing exfoliating agents
- Designed for periodic, not daily, application
- Part of Timeline’s two-step topical skincare system
- Developed using the brand’s Urolithin A research platform
Pros:
✅ Supports cellular energy and muscle strength with consistent use
✅ May help offset age-related decline in mitochondrial function
✅ Simple one-step addition to a daily supplement stack
✅ Backed by gold-standard clinical trial data
Timeline's bestselling softgels deliver a precise, concentrated dose of Urolithin A in the simplest available format, no flavoring or fillers involved. A landmark clinical trial cited by the brand found mitochondrial renewal increased by 39% after 16 weeks compared to placebo, a figure that has helped make Mitopure the most-discussed Urolithin A ingredient in longevity circles. The softgels suit adults focused on healthy aging, endurance, or strength maintenance without altering their exercise routine. Holding a 4.5-star average across more than 4,500 reviews, it is Timeline's most popular product. These statements have not been evaluated by the FDA, and this product is not intended to diagnose, treat, cure, or prevent any disease; pregnant or nursing individuals and anyone on medication should consult a doctor before use.

For those who prefer chewables over capsules, this sugar-free, strawberry-flavored gummy delivers the same core Mitopure ingredient in a more approachable format. It appeals to anyone who has struggled with pill fatigue or simply wants a supplement that feels less clinical day to day. With a 4.8-star rating from nearly 1,900 reviews, it holds the highest satisfaction score in Timeline's current lineup. As with the softgels, results build gradually over weeks rather than days, and individuals with dietary restrictions should review the ingredient label for sugar alcohols or allergens before starting.
Highlights:
- Sugar-free, strawberry-flavored gummy format
- Delivers the same Mitopure dose found in the softgels
- Rated 4.8 stars across approximately 1,875 reviews
- Convenient for travel or on-the-go supplementation
Final ThoughtsShoppers new to Urolithin A might start with either the softgels or gummies, Timeline's two most-reviewed products, before layering in the topical serum or exfoliator once a routine is established. Athletes and adults over 40 focused on strength and mitochondrial health are the clearest fit, while anyone expecting rapid, visible changes within days should temper expectations, since the clinical data points to gradual improvement over 16 weeks. Those on medication or managing a health condition should talk to a physician first, given the ingredient's systemic effects on cellular energy.
