Mechanistically, traditional explanations have focused on hemodynamic factors and macro- or microvascular damage
Both ranges contain the authorised fertility nutrients (zinc, selenium, folic acid, vitamin B6) but at different doses and alongside different additional ingredients
The mechanism is mechanical: slowed transit time allows colonic bacteria to ferment undigested carbohydrates longer, producing excess gas (methane and hydrogen)
Reductions in glutathione synthesis and tissue glutathione concentrations in aged animals (compared to younger ones) are suggestive of a potentially lower ability to respond to oxidative stress or toxin exposure (28)
As we age, our glutathione levels decline significantly , leaving us more vulnerable to oxidative stress, environmental toxins, and accelerated aging
