TIBC is a biomarker used for longevity, measuring the body's ability to bind and transport iron. Optimal levels support overall health and aging.

TIBC (Total Iron Binding Capacity)

TIBC, or Total Iron Binding Capacity, is a biomarker used in assessing overall health and longevity. It measures the body’s ability to bind and transport iron, which is essential for various biological processes. Elevated TIBC levels can indicate iron deficiency, while low levels may suggest iron overload. Maintaining optimal TIBC levels is crucial for longevity, as iron imbalance has been linked to accelerated aging and age-related diseases. Regular monitoring of TIBC, in conjunction with other biomarkers, can provide valuable insights into an individual’s overall health and help in creating personalized strategies for promoting longevity.

Biomarker Explained

Total Iron Binding Capacity (TIBC) is a vital biomarker used in evaluating overall health and promoting longevity. TIBC measures the body’s capacity to bind and transport iron, which is crucial for various biological processes. Elevated TIBC levels may indicate iron deficiency, while low levels could suggest iron overload. It is important to maintain optimal TIBC levels, as an imbalance in iron has been connected to accelerated aging and age-related diseases. Regular monitoring of TIBC, alongside other biomarkers, offers valuable insights into an individual’s overall health and aids in creating personalized strategies for promoting longevity. By interpreting TIBC levels, healthcare professionals can better assess an individual’s iron status and make informed decisions regarding their health and longevity.

How does Rapaymcin work?

Rapamycin slows aging by targeting the mTOR pathway, shifting the body’s focus from growth to repair. It promotes cellular recycling, reduces overgrowth linked to disease, and enhances resilience to stress.

Imagine your body as a city, bustling with activity.

Cells are the workers, and mTOR (mechanistic target of rapamycin) is the city planner, deciding where to focus resources – building new structures, cleaning up waste, or repairing old ones.

As we age, mTOR often prioritizes building (cell growth) over maintenance (cellular repair), leading to “clutter” in our bodies that contributes to aging and disease.

This is where Rapamycin comes in.

It acts like a wise advisor to mTOR, convincing it to slow down unnecessary growth projects and focus on clean up and repair instead.

Specifically, Rapamycin:

Activates cellular recycling (autophagy):

Think of autophagy as the city’s waste management system. Damaged parts of cells are broken down and reused, keeping the system efficient and healthy.

Reduces harmful overgrowth:

Overactive mTOR has been linked to diseases such as cancer, cardiovascular disease, and neurodegenerative conditions like Alzheimer’s. By dialing back excessive growth signals, Rapamycin helps prevent these issues.

Supports stress resilience:

When cells are less focused on growing, they’re better equipped to handle stress, repair damage, and maintain long-term health.
