Direct recommendation

I do measure DHEA-S — the sulfated form — in patients over 50.

Extracted claim

In his practice, Attia measures DHEA-S — the sulfated form — in patients over 50.

Partially supportedHigh confidence

The published literature consistently establishes DHEA-S as a clinically meaningful biomarker, particularly in the context of aging. The adrenopause review (PMID: 18839621) specifically documents the…

Direct recommendation

if you see somebody that has low double digit levels of DHEA right um in highend which is actually usually caused by stress right yeah it's very often caused by stress it's an easy supplement to take um you you supplement them with DHEA and then all of a sudden the hormone production starts again

Extracted claim

Low double-digit DHEA levels, which are often caused by stress, can be treated with DHEA supplementation, after which hormone production resumes.

DHEA sulfate this is a hormone that looks at your adrenal function adrenal function is connected to your sex hormones but often as we're under stress as we age our DHA levels go down and we tend to age faster we tend to have more fatigue we tend to have less libido we tend to have other issues

Extracted claim

DHEA sulfate is a hormone that reflects adrenal function, which is connected to sex hormones; as people experience stress and aging, DHEA levels decline, leading to faster aging, more fatigue, less libido, and other issues.
