DHEA-S

What it measures 

Measures the upstream precursor hormone that drives sex hormone production and is one of the most reliable markers of biological aging. Paired with cortisol, reveals whether your body is in a building or breakdown state. 

Best for 

Anyone over 35 experiencing unexplained fatigue, reduced drive, muscle loss, or hormonal changes. Particularly useful alongside a cortisol result. 

If results need attention 

Your Protocol doctor will contextualise your levels against your age and other hormone markers, and suggest a personalised plan. Note: DHEA supplementation is not approved in Singapore, so guidance will focus on lifestyle and specialist referral where needed.
