The Benefits of KEEY

KEEY is Extensia's flagship supplement, meticulously crafted to combat all 12 hallmarks of aging and enhance your overall well-being. Experience transformational benefits that help you look and feel your best.

  • Boost Energy Levels: Reclaim youthful vitality and combat age-related fatigue. Ingredients like NMN support increased NAD+ levels, leading to enhanced energy and strength for an active lifestyle.
  • Enhance Cognitive Function: Stay sharp and mentally agile. Brain-supporting compounds like Spermidine and Fisetin are included to promote memory and cognitive function as you age.
  • Promote Longevity: Stay younger for longer. Our blend targets all hallmarks of aging with ingredients like Quercetin and Alpha-Ketoglutarate (AKG), associated with improved health markers and longevity in various studies.
  • Slow Down Skin Aging: Combat visual signs of aging from within. Ingredients such as D-Glucosamine and AKG help reduce wrinkles and improve skin elasticity, combating visible signs of aging.
  • Strengthen Immunity: Support your body's natural defenses. Compounds like Curcumin and Fisetin aid in immune function, helping you stay healthier as you age.
  • Improve Physical Performance: Maintain strength and mobility. Ingredients like NMN and Betaine (TMG) support muscle mass and physical performance, vital for an active lifestyle.

10 Highly-Effective Ingredients

KEEY combines the power of ten scientifically-backed ingredients, each selected for their proven ability to support longevity and overall well-being:

  • Nicotinamide Mononucleotide (NMN): Enhances energy output and promotes a longer lifespan by increasing NAD+ levels.
  • D-Glucosamine: Boosts collagen production, improving skin elasticity and reducing wrinkles, promoting a more youthful appearance.
  • Spermidine: Linked to a lifespan extension of up to 30% in model organisms and improved longevity markers in humans.
  • Fisetin: May enhance cognitive function and memory while helping to eliminate senescent cells that contribute to aging.
  • Quercetin: Clinically proven to target and eliminate senescent cells, playing a vital role in extending healthspan and reducing the effects of aging.
  • Alpha-Ketoglutarate (AKG): Reduces low-grade inflammation, a key driver of aging, by up to 80% in mammals, and may decrease biological age by up to 8 years.
  • Betaine (TMG): Shown to increase muscle mass and enhance strength and performance in clinical trials, supporting physical vitality.
  • Lithium: Low-dose supplementation has been linked to improved health outcomes, including neuroprotective effects.
  • Curcumin: Improves vascular health by enhancing endothelial function and reducing oxidative stress.

Great product but

I absolutely love the product,
But the company has a bad habit of not shipping the product on schedule
I mean, you buy three months and sometimes you don’t get your second month until you’re all out of your first month
I don’t know why they don’t ship out all three of them at the same time

I've been following the longevity science for years, and Keey is a game changer. Basically, It's replaced 90% of my previous supplement stack. Now all I take in addition is my collagen, a multivitamin, and my Omega-3s.
