Cortisol is a hormone produced by the adrenal glands that helps regulate the body’s stress response, energy availability, immune activity, and daily (circadian) rhythms.
Cortisol level at the time of collection (often morning if specified).
Educational insight into stress-response signaling; timing is crucial for interpretation.
DHEA‑S (Dehydroepiandrosterone sulfate) is an adrenal-derived hormone that serves as a precursor for other hormones (androgens and estrogens) and is often discussed in the context of stress physiology and healthy aging.
DHEA-S, an adrenal-derived hormone precursor.
Used in wellness education related to stress physiology, aging, and hormone precursor availability.
Vitamin B12 is a water-soluble vitamin important for red blood cell formation, nerve health, and energy metabolism. Cobalamin is the primary form measured in blood.
Vitamin B12 status in blood.
Used in wellness education around energy metabolism, nerve support, and red blood cell formation.
Folate is a B‑vitamin important for DNA synthesis and red blood cell production. It works closely with vitamin B12 in one‑carbon (methylation) metabolism.
Folate status in blood.
Supports education around methylation pathways and red blood cell health; works closely with B12.
Magnesium is an essential mineral involved in muscle, nerve, and energy function. RBC magnesium reflects magnesium inside red blood cells and is sometimes used as a proxy for longer-term cellular status.
Magnesium measured within red blood cells (cellular magnesium status).
Provides educational insight into longer-term magnesium status which can relate to muscle function, sleep, and metabolic wellness.
Vitamin D is a fat-soluble vitamin important for bone and immune function. 25‑hydroxy vitamin D is the standard blood marker used to estimate vitamin D status.
25-hydroxy vitamin D, the standard marker of vitamin D status.
Supports education around bone, immune, and overall wellness. Seasonal changes and supplementation can affect levels.
Ferritin is a protein that stores iron in the body. Blood ferritin is often used as an estimate of iron reserves, though it can also rise with inflammation.
A marker that generally reflects iron storage.
Helps contextualize iron reserves in energy and performance discussions; also can rise with inflammation.
