Common Questions
Frequently asked
A balanced diet covers most needs, but certain nutrients like Vitamin D, magnesium, and omega-3s are commonly deficient even in healthy diets.
It depends on the nutrient. For most, the bioavailable form matters more than natural vs. synthetic. Look for methylated B vitamins and chelated minerals.
Supplements aren't regulated by the FDA the same way drugs are. Third-party testing verifies that what's on the label is actually in the bottle.
