Frequently Asked Questions on Longevity

LongevLife is Israel's AI-based Longevity platform. The system estimates your biological age, analyzes blood tests, and builds a personalized scientific protocol to improve health and longevity. The name expresses the connection between Longevity and Life.

Longevity is a scientific field concerned with how to live more years and at higher quality. The goal is not just to "live to 100" but to be 70 with the energy, sharpness, and strength of a 50-year-old. In research this is called improving Healthspan, the healthy years of life.

Anti-aging looks mainly at outward appearance: skin, wrinkles, hair. Longevity looks at internal physiology: organ function, cellular health, blood markers, biological age. LongevLife focuses on Longevity, not aesthetic treatments.

Lifespan measures how many years you live. Healthspan measures how many of them you live in health, independence, and full function. Per Global Burden of Disease data, the average Israeli lives to 83 but the last 15-20 years come with functional decline. Longevity aims to close that gap.

Biohacking is the use of scientific methods for biological optimization. In a scientific approach there are three levels: lifestyle (sleep, nutrition, movement), supplements and measurement (NMN, CoQ10, wearables), and advanced interventions (under medical supervision). LongevLife works on the first two levels.

David Sinclair (Harvard) research on Sirtuins and NAD+. Elizabeth Blackburn Nobel laureate for the discovery of telomeres. Steve Horvath Developed the epigenetic clock for measuring biological age. Peter Attia A Longevity physician who makes the science accessible to the general public.

Epigenetics is changes in gene expression without changing the DNA itself. With age, epigenetic changes accumulate and affect cell function. The good news: epigenetic changes are reversible. Lifestyle, nutrition, and supplements can shift gene expression for the better.

Senescence is a state in which cells stop dividing but do not die. Such cells secrete inflammatory substances that harm neighboring cells. The accumulation of senescent cells is one of the central mechanisms of aging. Senolytics are compounds that help clear these cells.

Per the landmark Nature paper (2013, updated 2023): 1. genomic instability, 2. telomere attrition, 3. epigenetic alterations, 4. loss of proteostasis, 5. decline in NAD+/Sirtuins, 6. deregulated nutrient sensing, 7. mitochondrial dysfunction, 8. cellular senescence, 9. altered intercellular communication.

Biological age is a measure of the age of your cells, as opposed to chronological age which counts days. Two 50-year-olds can show completely different biological ages: 42 for one and 61 for the other. The difference shows up in blood tests, energy, focus, and flexibility. Biological age can be improved.

Four main methods: DNA Methylation An "epigenetic clock" test, the most accurate (companies like TruAge). Telomere length a measure of chromosomal age. Blood biomarkers CRP, HbA1c, Omega-3 Index, vitamin D, and more. Vitality Score LongevLife's, based on a questionnaire and blood tests.

Yes. Studies show that genetics determine about 20% of your aging. 80% is subject to lifestyle. Research-backed changes in nutrition, sleep, exercise, and supplements have shown a reduction of up to 6 years of biological age within a few months.

There is no specific average figure for Israel, but studies show that people with a healthy lifestyle (adequate sleep, a Mediterranean diet, exercise) present a biological age 5-10 years below their chronological age. People with an unhealthy lifestyle may present a biological age 10-15 years higher.

According to Longevity research, ordered by impact: 1. Sleep (most critical), 2. glucose regulation, 3. low chronic inflammation, 4. physical activity, 5. chronic stress, 6. nutrition, 7. exposure to toxins.

LongevLife's Vitality Score is a score from 0-100 calculated from a comprehensive questionnaire (energy, sleep, stress, focus, nutrition) and blood tests if uploaded. 70+ is considered good, 85+ excellent. The score updates with each daily check-in and lets you track improvement over time.

Two "epigenetic clocks" for measuring biological age. The Horvath clock (2013) measures the general biological age of tissues and organs. The GrimAge clock (2019) predicts mortality more accurately. Both are based on DNA methylation and are considered the gold standard in research.

NMN (Nicotinamide Mononucleotide) is a precursor to NAD+, a molecule that activates longevity genes (Sirtuins) and enables DNA repair. NAD+ levels drop 50% by age 60. Common dose: 250-500mg in the morning on an empty stomach. Studied in 21+ clinical trials on ClinicalTrials.gov.

Both are NAD+ precursors. NR is less expensive and has been studied for more years. NMN is considered more directly absorbed by some tissues. Research has not yet determined which is better. Both are safe to use per the existing clinical trials.

CoQ10 is an essential cofactor in the mitochondrial respiratory chain. The body produces it, but production declines from age 40. Ubiquinol is the active form, preferable after age 40. Recommended dose: 100-200mg with a fatty meal. A meta-analysis of 13 clinical trials (2022) showed efficacy in reducing fatigue.

Ubiquinone is the more common form in supplements. The body needs to convert it to Ubiquinol (the active form). After age 40, conversion capacity declines. So for people over 40, Ubiquinol directly is recommended - more expensive, but more effective.

Magnesium is involved in 300+ enzymatic reactions in the body. 70% of the population in Israel is deficient. For sleep: Magnesium Glycinate (400mg before sleep) is well absorbed and does not cause diarrhea. For cognition: Magnesium L-Threonate crosses the blood-brain barrier. For muscle relaxation: Magnesium Citrate.

The optimal level for Longevity: 50-80 ng/ml. Most Israelis are in the 20-30 range, considered "normal" but not optimal. Typical dose: 2,000-4,000 IU per day, always with K2 (MK-7) to direct calcium to the bones and not the arteries. Test levels before and after 3 months.

The research dose: 2-3 grams EPA+DHA per day. Check the Omega-3 Index in a blood test - above 8% is considered optimal. Most Israelis are at 4-5%. Use a quality fish-oil supplement with 500mg+ EPA+DHA per capsule. Store in the fridge to prevent oxidation.

Ashwagandha (KSM-66 is the most studied form) is an adaptogen that reduces cortisol. Chronic stress and high cortisol are significant drivers of accelerated aging. Dose: 300-600mg per day. Improves sleep, reduces anxiety, and supports thyroid function.

Resveratrol activates the SIRT1 gene in lab and animal studies. In humans the evidence is less clear-cut due to low absorption. Pterostilbene (a Resveratrol derivative) shows better absorption. NMN is currently considered more effective for the same purpose.

Yes, but with attention to timing. In the morning: NMN, vitamin D+K2, omega-3. With a meal: CoQ10 (needs fat for absorption). Before sleep: Magnesium Glycinate, L-Theanine. Consult a doctor if taking medications, especially blood thinners.

Because we count hours instead of measuring quality. Deep sleep (Slow Wave Sleep) is the stage in which the body repairs DNA, clears neurological waste, and produces growth hormone. 8 hours with 4 awakenings and 40 minutes of deep sleep is inferior to 6 deep hours. Measure HRV in the morning for a true picture.

Deep sleep (Slow Wave Sleep / N3) is the stage in which the body produces growth hormone, repairs tissue, and clears the brain via the glymphatic system. Healthy people need 1.5-2 hours of deep sleep out of 8 hours total. Below one hour is a significant deficit.

HRV (Heart Rate Variability) is the variation in time between heartbeats. High HRV = a flexible nervous system capable of recovery. Measured in the morning after sleep. Consistently low HRV signals excess stress, inadequate sleep, or overtraining.

17-19 degrees Celsius. The body needs to lower its internal temperature to enter deep sleep. A room that is too warm prevents this process. In Israel: an AC set to 18 is one of the best Longevity investments.

The half-life of caffeine is 5-6 hours. Coffee at 2:00 PM = half the caffeine still in the blood at 8:00 PM. To improve deep sleep: stop coffee after 1:00 PM. If you are especially sensitive, after 11:00 AM. Green tea contains L-Theanine, which balances the stimulating effect.

GABA (Gamma-aminobutyric acid) is the main inhibitory, calming neurotransmitter. Magnesium is an essential cofactor for GABA production. Magnesium deficiency = low GABA = difficulty relaxing and falling asleep. Magnesium Glycinate 400mg before sleep supports this axis.

Melatonin is not a "sleeping pill" but a time signal. A low dose (0.5-1mg) is effective for resetting the biological clock, especially for jet lag or shift work. A high dose (5-10mg), which most people take, is unnecessary and may impair natural production. Use it as a signal, not as a dose.

Mitochondria are the cell's "reactors" - they produce ATP, the energy molecule. A healthy heart cell contains 5,000 mitochondria. With age, their function declines and their number falls. Mitochondrial Biogenesis - the creation of new mitochondria - occurs mainly in response to Zone 2 training.

Zone 2 is an activity pace at which you can talk but breathe faster than usual. Brisk walking, easy cycling, relaxed swimming. This is the precise stimulus that creates Mitochondrial Biogenesis. 30-45 minutes, 3 times a week - one of the best Longevity investments.

Common causes: iron/ferritin deficiency, low vitamin D, low B12, hypothyroidism, magnesium deficiency, chronic inflammation, inadequate sleep, unbalanced glucose. Before supplements, do blood tests. Treating deficiencies is far more effective than any supplement.

An energy dip at 2:00-4:00 PM is caused mainly by a glucose spike after a lunch of simple carbs. Prevention: combine protein and healthy fat in every meal to stabilize glucose. A short 10-minute walk after a meal reduces the spike by 30%.

Glycation - a reaction between sugar and protein - damages collagen, DNA, and other proteins. Every glucose spike causes glycation. Over years, this is one of the significant drivers of accelerated aging. Stable glucose regulation = a central protection for biological age.

The Mediterranean diet is one of the most studied diets for Longevity. Its features: Extra Virgin olive oil, fatty fish, leafy vegetables, legumes, nuts, a little poultry and red meat. Improvements in inflammation markers, LDL, glucose, and cognitive function - all backed by clinical trials.

There is evidence of benefit: improved insulin sensitivity, reduced inflammation, stimulation of autophagy (cellular cleanup). The 16:8 protocol (16 hours fasting, 8 hours eating) is the most common. It is not for everyone: not for pregnant women, not for people with a history of eating disorders, and not without medical consultation.

Sulforaphane is a compound in broccoli that activates the NRF2 pathway - an important defense mechanism against cancer and aging. Tip: cut broccoli 40 minutes before cooking. The enzyme Myrosinase activates the Sulforaphane before heat destroys it. Broccoli sprouts contain 50-100x more.

Oleocanthal, the active compound in Extra Virgin olive oil, suppresses inflammation similarly to ibuprofen. In addition: Oleic acid (omega-9) supports heart health, and antioxidant polyphenols. 3 tablespoons a day reduce CRP (an inflammation marker) by 37% after 8 weeks, per studies.

Estrogen acts as a natural antioxidant and protects brain, heart, and bone cells. The drop in estrogen during perimenopause accelerates aging. Women after age 50 without HRT sometimes show accelerated biological age. Supporting hormonal health through nutrition and supplements is very relevant.

Ozempic Face is loss of facial volume during rapid weight loss with GLP-1 drugs. It is not a direct side effect of the drug but a result of losing weight too fast without supporting muscle-mass preservation. Prevention: protein 1.6-2g/kg of body weight, strength training, close medical follow-up.

Blood iron can be "normal" while ferritin (the iron store) is low. Ferritin below 30 is borderline and functionally problematic, even without anemia. Iron deficiency causes fatigue, hair loss, reduced focus, and shortness of breath. Test ferritin, not just a blood count.

Women respond differently to stress, supplements, and training. The HPA axis works differently. Women benefit more from strength training to preserve muscle mass after age 40. Prolonged fasting may harm the hormonal axis in women. Supplement doses are sometimes different too. One size fits all does not work.

The Oura Ring Gen 4 is considered the gold standard for sleep measurement. Advantages: accurate HRV, deep-sleep measurement by stages, body temperature, Readiness Score. Downside: a $5.99 monthly subscription. For anyone serious about in-depth sleep analysis.

A CGM (Continuous Glucose Monitor) is a small sensor on the arm that measures glucose 24/7. 14 days with a CGM teach you more about the body than 10 years of diets: which foods raise glucose, how exercise and sleep affect it, and when energy dips happen. Available without a prescription.

An Apple Watch is enough as an entry point: ECG, oximeter, basic HRV, and integration with Apple Health. If you already have an iPhone and Apple Watch, use them. For deeper sleep analysis, the Oura Ring is preferable. For athletes, a Garmin with 21-day battery.

A clinical trial tests an intervention (drug, supplement, protocol) in humans under controlled conditions. It passes Helsinki-committee approval, includes a control group (placebo), blinding (participants do not know whether they received the treatment), and structured follow-up. This is the highest standard of scientific reliability.

Four main advantages: access to innovative treatments before they are available to the public, close and free medical monitoring, a deep understanding of your body, and sometimes financial compensation. In the Longevity field, they usually look for healthy participants aged 40-70.

The Ministry of Health's MyTrial database (gov.il/he/pages/clinical-trials-website) lists all trials in Israel. You can search by topic, age, and location. For international trials, ClinicalTrials.gov contains 500,000+ trials, some of which accept participants from Israel.
