Compound in Strawberries Slows Aging in Mice – LEAF Science – 13-Jul-2017
Fisetin is a naturally occurring plant polyphenol from the flavonoid group.
It is found in many fruits and vegetables, such as strawberries, apples, persimmons, onions, and cucumbers.
Found to clear senescent cells in a petri dish.
No evidence that fisetin has a senolytic effect in mice in vivo.
When added to the diet of SAMP8 mice delays some of the accelerated aging.
Geroprotectors: Creatine – LEAF – 16-May-2017
Creatine is a small peptid and an important energy buffer in muscle cells.
The body produces approximately 1 gram of creatine per day.
Creatine is naturally-occurring in many foods, particularly meat and fish.
But cooking denatures it so difficult to get enough of it in your diet.
Has neuroprotective properties and may reduce brain lesions.
Applied as a cream creatine may restore skin elasticity and reduce wrinkles by replenishing collagen stores.
Geroprotectors: Magnesium – LEAF – 26-Mar-2017
Not everyone gets enough of this essential element which is vital for cellular processes.
The daily intake of magnesium should around 300 mg for women and 400 mg for men.
Cocoa, dark chocolate, bananas, dark leafy greens, avocados, sesame seed, dried fruit, nuts and dates are all rich sources.
Magnesium deficiency can contribute to hypertension and diabetes as well as affecting cardiovascular health.
Geroprotectors: Honokiol – LEAF – 21-Feb-2017
Honokiol is a lignan isolated from the bark, seed cones, and leaves of the trees of various Magnolia species.
Well documented antioxidant.
Inhibits inflammatory signals via the activation of the NF-kb protein complex.
Potential treatment for rheumatoid arthritis.
Further studies may be needed to ascertain its long term effects.
Geroprotectors: Glucosamine – LEAF – 19-Feb-2017
One of the most commonly used supplements frequently taken to promote joint health.
Glucosamine naturally occurs in cartilaginous joint tissues and is involved in protein and lipid synthesis.
Plenty of food sources but cooking denatures it so hard to get sufficient from diet alone.
Inhibits the NF-kB protein complex, a central mediator of inflammation and central to the aging process, especially when combined with chondroitin.
Studies have also shown a reduction of cancer mortality risk.
It may be worth considering as part of your health regimen.
Geroprotectors: Quercetin – LEAF – 31-Jan-2017
In various studies quercetin has demonstrated antioxidant, anti-bacterial, anti-inflammatory and anti-carcinogenic properties.
Quercetin is naturally found in some fruit and vegetables such as apples, onions and dark cherries.
But to get a typical dose (around 500mg) used for health purposes would mean eating at least fifty apples a day!
Quercetin is a naturally occurring member of the flavonoid family – a large family of water-soluble chemicals, which are not created by the body
Isoquercetin has the same benefits as regular quercetin has but has better bioavailability and absorption by the body.
Geroprotectors: Pterostilbene – LEAF – 28-Jan-2017
Pterostilbene has antioxidant, anti-inflammatory and anticarcinogenic properties.
Estimated content per blueberry varying between 99 ng to 520 ng – obtaining enough from dietary means isn’t really a realistic proposition.
Available as a dietary supplement from various suppliers.
Pterostilbene has increased bioavailability compared to resveratrol and other stilbene.
Increases sirtuins which are best known for their pro-longevity effects in dietary restriction experiments.

$50 per month for Elysium Basis probably is not the best investment of your supplement budget.
