Corrections
Accuracy matters on a health topic. If you think something in a guide is wrong or out of date, tell us which guide and what you'd change, with a source if you have one. We review every correction and update the guide's "Updated" date when we make a change.
We can't give personal advice
We aren't medical professionals and can't recommend supplements or doses for your individual situation. Please talk to a doctor or pharmacist, especially if you're pregnant, breastfeeding, taking medication, or managing a medical condition.
