RECOMMENDED RANGES
Men and women may need different context.
We only show a different amount when physiology, dietary requirements or clinical evidence supports it. Otherwise, we say the range is the same.Typical guidance
The typical adult range is often the same. Pregnancy, breastfeeding, fertility treatment and menopause may change appropriateness.
Important context: A separate male and female serving is not established for this intervention; avoid inventing a difference where research does not support one.
