"Take one serving daily" sounds simple until you ask what a serving actually is. On a fruit and vegetable supplement, the answer lives in one specific line of the Supplement Facts panel - and it means something more precise, and more limited, than most people assume.
1. The Serving Size line is the basis for the panel's amounts
Federal labeling rules for dietary supplements require the Supplement Facts panel to state a serving size, and the amounts declared on the panel are per that serving - with one permitted exception: the rules allow a product to add a separate "Per Day" column alongside the per-serving amounts. If the serving size is 3 capsules, then each declared per-serving total - including a proprietary blend's total weight - is the amount in 3 capsules, not in 1. Two products can declare identical blend totals while meaning different things per capsule, simply because their serving sizes differ.
The serving size itself is not an arbitrary number the maker picks. Under 21 CFR 101.12, the reference amount for a dietary supplement is tied to the maximum amount recommended per eating occasion on the product's label - or one unit (for example, one capsule) when the label makes no recommendation. The serving size you read is built from that framework.
2. A label serving is not a dietary-guideline serving
Nutrition guidance also uses the word "serving" - as in servings of fruits and vegetables per day. These are two different systems sharing one word. A dietary-guideline serving is a standardized food-measure unit used in healthy-eating guidance. A supplement label's serving size is the regulated basis for that product's panel, derived as described above. A capsule serving is not a counted serving of vegetables in the dietary-guidelines sense, and a label does not establish that equivalence. When a product's marketing implies its serving replaces food servings, that implication is not coming from the Supplement Facts panel - the panel does not say it.
3. Per serving vs. per day
The Serving Size line and the Suggested Use or Directions line are related but separate. Serving Size is the basis for the declared per-serving amounts; Suggested Use is how the maker recommends taking the product. On some products they match - a 3-capsule serving taken once daily. On others they differ: a 1-capsule serving with directions to take one capsule three times daily means your daily intake is three times every per-serving amount on the panel. Read both lines before doing any math with the numbers.
4. Turn the serving into bottle math
Once you know the serving size and the servings per container, the rest is arithmetic. A hypothetical 90-capsule bottle at 3 capsules per serving holds 30 servings; at a 3-capsule daily serving, that is a 30-day supply. The same numbers drive price comparison - our walkthrough of cost per serving for fruit and vegetable supplements uses exactly this math, and our capsules-per-serving equivalency guide covers the same line from the powder-comparison angle. When a product hides its serving size or declares amounts without a clear basis, you cannot compare it with another product on the same basis.
Where Vitamized stands
Vitamized Superfood Fruit & Vegetable Capsules are a 38 fruit and vegetable superfood blend with BioPerine, 3 capsules per serving, Made in USA. The serving size and the declared blend totals are stated on the photographed Supplement Facts panel on the product page - the panel is the basis, and it is there to read.
