Science & Ingredients

What makes Longelite exceptional?

✔ Developed based on scientific evidence
Our products are formulated based on current scientific knowledge, clinical studies, and expertise in the field of longevity. We use only ingredients that already have a certain amount of convincing evidence behind them and an excellent safety profile. In most cases, these are ingredients that have been tested (and have demonstrated both efficacy and safety) in randomized controlled trials in humans — the gold standard of modern science.

✔ Clinically relevant dosing
We do not use “cosmetic” or symbolic amounts. The doses of our ingredients correspond to the amounts that have shown efficacy in human clinical studies — even when this is sometimes more challenging and costly.

✔ Synergy, not a mix
Each formula is designed so that the individual ingredients act synergistically — they enhance each other rather than weaken each other. We focus on absorption, stability, and bioavailability, because only then can a supplement have a real effect.

✔ Transparency and purity
We take our formulations seriously. We do not use any unnecessary fillers, synthetic colorants, or chemical sweeteners — in flavored products we use only natural stevia, and in the future we plan an even better sweetener that is unfortunately not yet available in the Czech Republic. All active ingredients come from verified suppliers and are independently tested for heavy metals, microbial contamination, molds, pesticides, and other contaminants. Details matter — and with health products, this is doubly true.

Who is Longelite for?

For anyone who:

• wants to live longer and healthier,
• is looking for a science-backed approach to prevention,
• cares about health, energy, and mental performance,
• does not want to believe marketing, but scientific evidence,
• is looking for a reliable, clean, and transparent product.

How does Longelite fit into a healthy lifestyle?

Longelite is not a replacement for a healthy lifestyle — but it is a smart complement. It is designed to support in particular:

• Metabolic health (insulin sensitivity, glucose tolerance, lipid profile),
• Controlled inflammation (prevention of chronic inflammation),
• Mitochondrial health and DNA protection (cellular energy production and prevention of excessive oxidative damage),
• Health of key organs (skin, blood vessels, liver, brain, and others),
• Musculoskeletal system (support for performance, recovery, and building muscle mass),
• Resilience to environmental stress (e.g., UV, toxins, lack of high-quality sleep),
• Slowing biological aging – mechanisms at the cellular and systemic level.

Longelite vs. the competition?

While most supplements are built on trends, we follow the path of science. We fundamentally do not use ingredients with disproven efficacy. We do not believe in “magic pills,” but we formulate complex, science-backed supplements that can truly help you age more slowly, more healthily — and with greater joy in life.

Key longevity ingredients

Longevity cannot be built on one “miracle ingredient.” That is why at Longelite we use the synergy of the most researched molecules with the potential to slow aging at the cellular level, support regeneration, and protect against chronic lifestyle-related diseases. Among our key active ingredients are the following.

Antioxidants and cellular protection

Astaxanthin – the strongest natural antioxidant, protects mitochondria, eyes, skin, and the brain.
EGCG (green tea extract, catechins) – supports metabolism, reduces inflammation, protects DNA.
Curcumin – modulator of inflammatory pathways (NF-κB), benefits the brain and joints.
Ergothioneine – referred to as the “longevity vitamin,” protects mitochondria from oxidative stress.
PQQ (pyrroloquinoline quinone) – stimulates mitochondrial biogenesis, supports cellular energy.

Molecules linked to autophagy and cellular renewal

Apigenin – a flavonoid with potential senolytic activity, protects the nervous system.
Spermidine (wheat germ extract) – stimulates autophagy, associated with lifespan extension.
Nattokinase – an enzyme supporting cardiovascular health and blood circulation.

Metabolic health and prevention of lifestyle-related diseases

Berberine HCl – “natural metformin,” supports insulin sensitivity, glucose balance, and lipid profile.
Momordica charantia (bitter melon) – a traditional plant with effects on glucose metabolism.
Chromium picolinate – essential for blood sugar regulation and insulin response.

Essential micronutrients for longevity

Vitamin D3 + K2 (MK7) – synergistically support immunity, bone and vascular health, and hormonal balance.
Zinc, selenium, copper (chelated forms) – trace minerals essential for immunity, antioxidant enzymes, and hormonal balance.
Vitamin C – a fundamental antioxidant, important for collagen, immunity, and cellular protection.
