Mimio offers a clever, focused concept: a daily capsule of compounds the body produces during an extended fast. Its ingredients are individually studied and the product comes with a guarantee and HSA/FSA eligibility, but evidence for the finished formula in humans is limited and it costs about $90 a month.
What we like
- Clear, single-product focus with a simple two-capsule daily dose
- Ingredients such as spermidine, nicotinamide, PEA and OEA have been individually researched
- No dietary changes or fasting required
- 30-day money-back guarantee and HSA/FSA eligibility
- Compostable pouches and refillable tins
Keep in mind
- About $90 a month, or roughly $81 on subscription
- Headline lifespan results come from model organisms, not people
- Ingredient doses are not prominently shown on the homepage
- Only one product, so there is little choice
Fasting has become one of the most discussed strategies in longevity science, with research linking extended fasts to processes such as autophagy, the cell's way of clearing out damaged components. The catch is that multi-day fasts are difficult, uncomfortable and not appropriate for many people. Mimio Health was founded to offer a workaround: a daily supplement made from compounds that naturally rise in the body during a prolonged fast.
The company calls this approach biomimetic, meaning it aims to imitate the body's own chemistry rather than introduce something foreign. In our research we looked at who is behind Mimio, what is in the capsule, what the evidence does and does not show, and whether the monthly cost is likely to be worthwhile for you.
The company and its founder
Mimio was founded in 2023 by Dr. Chris Rhodes, who holds a PhD in nutritional biochemistry from UC Davis. The company says it spent around seven years researching how the body responds to fasting, focusing on which metabolites rise during a 36-hour fast and how they might influence cellular health.
The result is a single formula rather than a product range. That focus makes Mimio easy to understand: there is one product, one dose and one central idea. The brand describes its products as created by doctors and third-party certified, though it does not name the certifying body on its homepage.
What is inside the capsule
Mimio's formula combines four compounds that the brand says are naturally elevated during extended fasting:
- Spermidine, a polyamine found in foods such as wheat germ and aged cheese, which has been studied for its role in autophagy.
- Nicotinamide, a form of vitamin B3 and a precursor to NAD+, a coenzyme involved in cellular energy and repair.
- Palmitoylethanolamide (PEA), a fatty acid amide studied for its role in inflammation balance and discomfort.
- Oleoylethanolamide (OEA), a related compound studied for its role in appetite regulation through a receptor called PPAR-alpha.
The suggested use is two capsules daily. The brand recommends taking them with or before a meal, saying this may help increase satiety and reduce the metabolic impact of eating. The formula is vegan, gluten-free and non-GMO.

How strong is the evidence?
Each of Mimio's ingredients has its own research base, and the company says they are backed by more than 100 clinical studies collectively. That is not the same as evidence for the combined product, however. Mimio's most eye-catching claim, that its formula extended lifespan by up to 96%, comes from studies in model organisms, which are simple laboratory animals used in early research, not humans. Its claims about pathways such as autophagy, mTOR and AMPK are based on in vitro, or laboratory, research.
None of that makes the product worthless, but it does mean the benefits for people remain to be shown. The company says clinical studies are ongoing. For now, Mimio is best seen as a plausible, research-informed experiment rather than a proven longevity treatment.
Price, subscription and guarantee
A 30-day supply costs $90 as a one-time purchase. Subscribing takes 10% off and delivers automatically each month, bringing the cost to about $81. Mimio is HSA and FSA eligible, which can reduce the effective cost for people with those accounts, and it comes with a 30-day money-back guarantee.
Packaging is designed to reduce waste, with compostable refill pouches and refillable tins. Shipping costs are shown at checkout.
Using Mimio sensibly
- Be clear about your goal. If you want to support healthy aging without fasting, Mimio fits that brief. If you want to lose weight, diet and activity will do far more.
- Give it time. Effects on cellular processes are not something you will feel quickly, so commit to the guarantee window and then reassess.
- Keep foundations in place. Sleep, exercise and a nutrient-rich diet have far stronger evidence for healthy aging than any single supplement.
- Check interactions. If you take medication or other NAD+ precursors, review overlapping ingredients with a clinician.
Who it suits
Mimio is aimed at longevity-curious adults who like the science of fasting but find extended fasts impractical, people already interested in compounds such as spermidine or NAD+ precursors and those who prefer a single, focused product over a large stack. The guarantee lowers the risk of trying it.
It is less suited to budget shoppers, anyone who wants proven outcomes before paying, or people who expect to feel immediate effects. If you are pregnant, breastfeeding, managing a medical condition or taking medication, check with your doctor first.
How it compares with other longevity products
Many longevity supplements focus on a single pathway, such as NAD+ boosters built on NMN or nicotinamide riboside, or urolithin A products aimed at mitochondrial renewal. Mimio's approach is broader in concept, combining several compounds tied to the fasting response in one capsule. Structured fasting-mimicking diet kits take a different route again, replacing food for several days with a set meal plan. Compared with those kits, Mimio requires no change to how you eat, which makes it easier to sustain but also means it is unlikely to replicate everything a fast does. If you already take an NAD+ precursor, check for overlap with Mimio's nicotinamide before combining products.
Our verdict on Mimio Health
Mimio is one of the more intellectually coherent longevity supplements available, with a clear concept, a credentialed founder, sensible packaging and a money-back guarantee. Its main limitation is evidence: the finished formula's benefits in people have not yet been established, and the lifespan claims come from model organisms. For informed buyers who understand that, it is a reasonable product to explore in 2026. Use the 30-day guarantee as a trial period, and treat it as an addition to, not a replacement for, the everyday habits with the strongest evidence for healthy aging.
