Longevity

Longevity without the hype: keep an eye on the basics.

Aging well starts with exercise, food, sleep and regular check-ups with your doctor, not with magic pills. berryl shows you protein, fiber, your supplements and body measurements in one place. With Premium, every note names its source.

What longevity is about

Longevity literally means a long life. What people usually mean is something else: as many healthy years as possible. Half of the people aged 18 to 70 asked in Germany know the term, and more than two thirds see potential in it. That was the result of a Forsa survey for the German health insurer DAK-Gesundheit in August 2026. 74 percent would move more, 71 percent count on social contacts, and 59 percent see better sleep as an important approach.

The evidence is strongest for the unspectacular. In the article on the survey, Prof. Stefan Kluge, scientific director of the Longevity Forum Deutschland, names this foundation: not smoking, regular exercise, a balanced diet and enough sleep. He adds keeping classic risk factors such as high blood pressure, high blood lipids or diabetes under control. For some expensive tests and dietary supplements, on the other hand, a proven benefit is missing, he says.

The basics in numbers

AreaGuidanceSource
Exerciseat least 150 to 300 minutes of moderate or at least 75 to 150 minutes of vigorous activity a week, plus muscle-strengthening activity of at least moderate intensity for all major muscle groups on 2 or more days. From 65, as part of this, varied activity of at least moderate intensity on 3 or more days that focuses on balance and strengthWHO 2020
Proteinabout 0.8 g per kilogram of body weight a day for healthy adults (US RDA 0.8 g, EFSA 0.83 g); the DGE (Germany) gives 1.0 g from age 65 (estimated value)NIH, EFSA, DGE
Fiber25 g a day for adults (EFSA); in the US 14 g per 1,000 kcal, about 25 to 38 gEFSA, National Academies

What berryl shows

Your numbers in one place.

Protein and fiber

Log food by search, barcode or photo. berryl shows protein and fiber next to calories. You set your own protein goal.

Supplements added up

Vitamin D in your multivitamin and in a single product? berryl adds up food and supplements and compares the total with the upper limits.

Sleep and activity

Steps, sleep, resting heart rate and HRV from Health Connect or from a wearable such as WHOOP. You decide what berryl may read.

Body measurements

Weight, blood pressure, blood sugar, body fat and circumferences with date and time, entered by hand or from your scale via Health Connect.

With a source

With Premium, every note names its source. Where nutrition data, reference values and upper limits come from is explained on How berryl calculates.

What berryl deliberately does not do

  • No “biological age” and no longevity score. Numbers like these combine many values into one. How well that works is not sufficiently backed by evidence. berryl shows each value on its own, next to its reference.
  • No supplement recommendations. berryl adds up what you take and points out upper limits. What you take is your decision, ideally with advice from your doctor or pharmacist.
  • No diagnosis. berryl gives you information. Your doctor interprets your health values.

Longevity supplements: what is allowed

Many substances are marketed around longevity. Whether they may be sold as food in the EU at all is regulated very differently. Health claims such as “slows aging” are not authorized for any of these substances.

SubstanceStatus in the EU
NMN (nicotinamide mononucleotide)Novel food, not authorized so far. In May 2026, EFSA assessed one NMN product as safe. The decision of the European Commission is still pending.
SpermidineA wheat germ extract with a high spermidine content is authorized, with a defined specification and conditions (Union list of novel foods). There are no authorized health claims for spermidine.
CreatineAvailable as a food supplement. For adults over 55 there is one authorized claim: “Daily creatine consumption can enhance the effect of resistance training on muscle strength in adults over the age of 55.” It applies to adults over 55 who do regular strength training: with 3 g of creatine a day and resistance training in which the workload can be increased over time, performed at least three times a week for several weeks, at an intensity of at least 65 to 75% of the one-repetition maximum.

As of October 2026. Sources: EFSA opinion on NMN (CIRS), German consumer advice center (Verbraucherzentrale) on NAD and NMN, Union list, Implementing Regulation (EU) 2017/2470, amended for spermidine by (EU) 2020/443, Implementing Regulation (EU) 2017/672. Not legal advice.

Already taking something like this? Then talk to your doctor or pharmacist about it, especially if you take medication.

Fasting timer and habits

Both are in the app and both are optional. With the fasting timer you choose a plan such as 16:8, 18:6 or OMAD or set your own number of hours. berryl shows how long you have been fasting and can remind you when it ends. For 24 hours and longer, the app advises talking to your doctor first.

With habits you tick off what you set out to do, such as strength training, a fixed bedtime or time with friends. berryl counts your streak and reminds you if you want. Ideas to get started are included.

If you only want to use berryl for nutrition, just leave both out: you choose which areas appear in the menu bar.
