Your body produces a powerful longevity protein called Klotho (α‑Klotho). First discovered in 1997 and named after the Greek Fate who spins the thread of life, Klotho has been the subject of nearly 30 years of research and over 3,000 published studies. Today, science confirms that this protein is essential for vitality, cognition, and healthy aging.
Produced primarily in the kidneys, brain, and liver, Klotho acts as both a cell-surface receptor and a circulating hormone. Its levels remain highly stable throughout the day, providing continuous support to your body's vital systems.
Research consistently links higher Klotho levels to profound health benefits, including:
Our natural Klotho production steadily decreases as we age, driving systemic decline, including ovarian aging and metabolic dysfunction.
We now know that it is possible to boost Klotho levels to improve cognition and health. This platform provides a comprehensive summary of how Klotho works, the evidence supporting its benefits, and actionable natural and therapeutic approaches to optimize your Klotho levels.
Disclosure: We serve as consultants and distributors for multiple options listed here, and we can refer inquiries to all known available options. Our goal is to help you find the best fit for your individual needs. To that end, we are committed to providing transparent, science-backed information that clearly outlines both the risks and benefits associated with each approach.
Higher klotho levels are linked to improved cognitive function, synaptic resilience, and protection against age-related neurodegeneration and ApoE4-related vulnerability.
Elevated klotho levels are associated with better cardiovascular function, reduced arterial stiffness, lower risk of heart disease, and lower vascular inflammation and oxidative stress.
Higher klotho is linked to increased lifespan, resilience to age-related decline across multiple tissues, reduction of oxidative damage, improvement of metabolic regulation and cellular homeostatis.
Elevated klotho levels support muscle function, physical resilience, promotes muscle regeneration, mitochondrial health, and reduced inflammatory signaling in muscle tissue.
Klotho can be increased through exercise and diet.

A variety of klotho protein "peptides" are readily available. The protein itself is very unstable with a short half life of approximately 6 hours so injections are generally daily to keep klotho levels up.
There is a USA brand launched December 2025 which claims their "albumin binding klotho" lasts for 17 days and may be injected every 2 weeks. There is some concern that this type may eventually lead to one's body rejecting their own natural klotho, and this specific type has not been shown to be effective for cognition or longevity as no data is available yet. We look forward to seeing some research on this product.
Costs depending on the type are approximately US$600-$1,100/month or $7,200-$13,200/year
Klotho gene therapy via AAV (Adeno-associated virus) has been available for several years in South America. One intramuscular injection is purported to last for 3-5 years and costs between US$120,000 to $250,000.
The concern with AAV is that one may produce an immune response to the viral vector (high dose prednisone is recommended for 1 month to dampen the immune system). A strong antibody response may prohibit the use of a therapy using AAV in the future, making it a one-time treatment. There may be an integration risk with some AAVs.
A 5 person study using an AAV intranasal delivery model using a combination of klotho and h-tert in 2021 can be found in the Science page.
mRNA delivered in lipid nanoparticle (LNP) formulations provides cells with transient instructions to produce Klotho protein without altering genomic DNA. The approach uses synthetic KL‑encoding mRNA encapsulated in LNPs (Lipid Nano Particles) with PEG (Polyethylene Glycol) for systemic or local delivery, producing protein expression for days to weeks per dose and enabling repeat dosing as needed.
Klotho gene therapy via MRNA technology lasts a few to several weeks. It is recommended to "top up" every 2-3 months utilizing a theory that klotho levels are best "pulsed" in extremely high levels. This may be contrary to human studies demonstrating that klotho levels remain relatively steady through the day and the optimal levels for improved health and reduced risk of many chronic disease are levels above 603-698 pg/mL with a natural human range of 285.8–1,638.6 pg/mL.

Approximate cost: US$35,000 in Central America
mRNA klotho is currently in a trial which will measure the development of anti-PEG antibodies with repeat dosing.
Anti-PEG antibodies may cause immunogenicity, rapid elimination of a drug upon repeat dosing, may trigger complement activation, which may lead to adverse events ranging from injection site reactions, to cardiovascular events, to anaphylaxis.

Klotho plasmid delivery could be referred to as a klotho production booster. It uses pure DNA, is non integrative (not Crispr) and does not alter genes.
Polymers
Klotho plasmid therapy using a polymer such as low molecular weight PEI (Polyethylenimine) to shuttle the DNA into the nucleus either intramuscularly, intranasally, or subcutaneously. This method has very low toxicity and may be repeated. It has been available for 3 years in Asia. A subcutaneously version has been available more recently in Central America.
This method is non-integrative - the DNA sits separately from the genome. No serious adverse effects have ever been reported with the use of klotho plasmids.
Duration depends on several factors, approximate duration are: intramuscular injection 12+ months, the intranasal up to 1 year. The primary differences are the intranasal affects the brain, whereas intramuscular affects brain and body. Low dose methylprednisone or dexamethasone may be used for 3-5 days to increase optimal transfection.
The estimated price for intranasal is US$7,000, intramuscular US$25,000-$30,000.
Subcutaneous is estimated to be available for US$30,000-$50,000 and may last up to 12 months.
Electrical Current
Klotho plasmid therapy using electrical pulses is non-integrative and uses micro-pulses to open pores for pure DNA delivery. This is the most straight forward pure delivery method without the use of methylprednisone or anything other than the DNA, glucose and a sterile water solution. Lasts 12+ months.
Approximate cost US$25,000-$30,000 depending on location and services.

3 Months after Intramuscular Klotho Plasmid
Since I’ve had the klotho treatment a few months ago I have enjoyed a lot more energy and verve. Not only did I feel cognitively sharper, but importantly...I perceived the world through rose tinted glasses, as if I were in my twenties again. It restored my youthful, invaluable, spring in my step.

5 Months after Intranasal Klotho Plasmid (TBI)
After a head injury my cognitive function deteriorated. Over years I was able to function relatively normally, but after the klotho drops I found my thinking and mental skills increased. I feel normal again.
