Ferritin often detects iron deficiency earlier than hemoglobin. Learn why non-anemic iron deficiency can cause fatigue and brain fog, how to interpret ferritin with other labs, who may benefit from testing, and how traditional food strategies support iron—while avoiding iron overload risks.
foundations
Ferritin often drops before hemoglobin and may reveal non-anemic iron deficiency behind fatigue, brain fog, and restless legs. Learn why ferritin matters, who may need testing, and how diet and traditional practices influence iron status—while staying mindful of iron overload risks.

A focused, evidence-based look at MTHFR polymorphisms—what they change in methylation, how common they are, and what matters most (homocysteine and B vitamin status) versus hype.
foundations
A clear, evidence-based look at homocysteine as a methylation marker—what raises it, what it predicts, and how food-first strategies with B vitamins support healthy levels.
