Blood values and your metabolism
Your blood values make your metabolism visible. Sugar, fats and thyroid all help decide how easily you lose weight. Look up a value below. Each one gives the normal range and what a deviation means.

Vitamin C
Vitamin C is considered especially important for older adults, as it may support immune function, wound healing, and antioxidant protection against age-related oxidative stress. Dietary intake may vary with changing eating patterns. Healthcare providers can help assess your needs.
Vitamin D (25-OH)
Your vitamin D levels show how much reserve you have to absorb calcium. Bones and muscles are the first to notice an empty store. How the number is read depends on your age. Below seventy, 40 nmol/l counts as insufficiency. From seventy, the same result is a deficiency. So the value is rarely read on its own. It is read alongside calcium, phosphate and parathyroid hormone. Your medication counts too. Some anticonvulsants and long-term corticosteroids speed up the breakdown.
Vitamin E
Vitamin E supports healthy ageing by protecting cells from oxidative damage. Maintaining adequate levels may contribute to cognitive health and cardiovascular well-being as you age.
Vitamin K1
Vitamin K1 becomes especially important for bone health as you age. Adequate levels support blood clotting and may help maintain bone density in later years.
Zinc
Zinc supports immune health, wound healing, and cognitive function — all important for maintaining well-being as you age. Absorption may decrease with age, making monitoring valuable.
eGFR (Estimated Glomerular Filtration Rate)
In excess weight and early diabetes the kidneys often filter too hard. That hyperfiltration produces a high eGFR that looks reassuring but is a risk signal. This page explains how weight and blood sugar drive kidney function.
hs-CRP (High Sensitivity CRP)
hs-CRP measures the chronic inflammation associated with cardiovascular ageing. Regular monitoring is a cornerstone of heart health management in later years.
