What to know first
- Start with serving size and servings per container.
- Compare the amount per serving with the dose used in credible research or professional guidance.
- “Daily Value not established” does not prove an ingredient works.
Read in the right order
First check the serving size: two capsules can turn a seemingly low price into half as many days of use. Next review each dietary ingredient, its chemical or botanical form, the amount per serving, and percent Daily Value when one exists.
Then read “other ingredients” for fillers, colors, sweeteners, capsule materials, and potential allergens. The manufacturer or distributor and net quantity should also be clearly identified.
Interrogate the claim
A high percent Daily Value is not necessarily more beneficial, and it may increase risk. A proprietary blend can disclose total blend weight while hiding individual amounts, making evidence and safety comparisons difficult.
Keep the label or a photo for your clinician and pharmacist. Check whether the total from food, fortified products, and multiple supplements exceeds recommended or upper intake levels.
