Mindsip insights from this episode:
Utilize 30 mg/kg Vitamin C dosage for optimal health benefits
The effective oral dose of Vitamin C used in the monkey study was 30 mg per kilogram of body weight, which translates to 2,400 mg for an 80 kg person.
Lower blood iron levels with Vitamin C for anti-aging benefits
One way Vitamin C likely protects against faro aging is by dramatically pushing down elevated blood iron levels.
Link iron overload to aging process through gene activity
Genes that are especially active during iron overload significantly overlap with general aging-related genes, suggesting a direct link between iron and the aging process.
Investigate 'faro aging' linked to iron accumulation in the body
A new form of aging called 'faro aging' is being studied, which is linked to the accumulation of iron (Fe) in the body over time.
Supplement Vitamin C to reduce faro aging in older monkeys
In old monkeys, supplementing with Vitamin C significantly reduced their faro aging score, making it similar to that of middle-aged monkeys.
Limit excess iron to prevent damaging Fenton reaction
Excess iron increases the odds of the Fenton reaction, which creates highly unstable hydroxyl radicals that damage cell membranes and DNA.
Monitor iron levels across organs as you age
As we age, iron levels consistently elevate not just in our blood but also in tissues like muscle, lung, heart, and liver.
Reduce iron intake to enhance physical performance
In mice, a high-iron diet led to not only increased DNA damage but also made them weaker, slower, less coordinated, and less cognitively sharp.
