How to compare
whole-food supplement labels.

Comparing whole-food supplements starts with the label for the exact product you are considering. Read the serving size, disclosed ingredient amounts, other ingredients and directions together. A long ingredient list is a starting point for questions, not a way to predict your results.

1. Identify the exact product and serving

Write down the full product name and format before comparing two labels. The NIH Office of Dietary Supplements explains that a Supplement Facts panel includes the serving size, dietary ingredients, amounts per serving and Daily Values where established. Check whether a serving means one scoop, several capsules or another quantity. Compare amounts per serving rather than the package size alone. Read NIH’s explanation of supplement labels.

2. Separate listed ingredients from disclosed amounts

FDA explains that individual amounts may not be disclosed for ingredients within a proprietary blend. Seeing a plant named on a label therefore does not always tell you its individual quantity. Mark an undisclosed amount as unknown instead of estimating it from a photograph, ingredient count or another product’s label. See FDA’s dietary supplement questions and answers.

3. Read the other ingredients and directions

Check the full label, including the other ingredients, not just the front of the container. NIH identifies flavors, sweeteners and binders among ingredients that can appear outside the Supplement Facts panel. Keep the exact product’s directions and cautions with your comparison. A powder and a capsule sharing a brand name should each have their own column on your notes.

4. Turn the comparison into questions

• Can I read the current label clearly, including the serving size?
• Which amounts are disclosed, and which remain unknown?
• What ingredients or cautions do I need to discuss with a pharmacist or clinician?
• Does the preparation or capsule routine fit how I would actually use the product?
• What are the current seller’s price, shipping and return terms?

FDA advises talking with a doctor, pharmacist or other health professional before purchasing or using a supplement because interactions can occur. Bring the actual label and your medication and supplement list. FDA also explains that it does not approve dietary supplements before they are marketed. A label is product information, not a substitute for that conversation.

Use the checklist with the Feast guide

Our Premium Feast and Turbo Charged powder guide includes label viewers beside the powder options. There is also a Turbo Charged capsule option; use its own seller-provided label and directions. Open the relevant label, record the information above, and ask the seller about anything that is missing. Current formulas and offers can change.
