Evidence-based nutrition, in plain English — every entry sourced from clinical research.

Folate is the natural form of vitamin B9, the leafy-green vitamin that takes its very name from “foliage”. It is abundant in spinach, lentils, asparagus, broccoli and citrus fruit, and is the nutrient famously needed before and during early pregnancy to help a baby’s neural tube close properly. Beyond pregnancy, folate is busy in every dividing cell, building DNA and renewing blood. The water-soluble form is fragile, so prolonged boiling leaches much of it away; light steaming or eating greens raw preserves far more.

What is Folate?

Folate is a water-soluble B vitamin that plays a critical role in synthesising and repairing DNA, forming red blood cells and supporting healthy growth in pregnancy. While many general diets overlook it, maintaining optimal levels of Folate is frequently tracked by people working to optimize their Homocysteine.

How Folate Impacts Homocysteine

Research links diets rich in Folate to changes in Homocysteine. Diets naturally abundant in this compound often support lower Homocysteine markers by supplying the methyl groups that, together with vitamin B12, convert homocysteine back into methionine and keep this remethylation cycle turning.

Encyclopedia Insight: For maximum absorption, pair Folate-rich foods with vitamin B12 from animal foods, its partner in the same remethylation pathway, plus gentle cooking to protect this heat-sensitive vitamin to optimize bioavailability.
