What goes in a supplement spec sheet

The product specification sheet is the single most important document in supplement manufacturing that nobody outside the industry has heard of. It is the definitive description of what the product is — the reference that production builds to, that QA tests against, that customers and auditors rely on. A vague or inconsistent spec sheet causes problems everywhere downstream; a complete, accurate one prevents them. Here is what a proper spec sheet contains, and why it should come from the formula rather than a blank template.

Product identity and format

The spec opens by defining what the product is: its name, format (capsule, tablet, powder), the dosage form details, the unit and serving size, and the pack configuration. This frames everything that follows — a per-capsule spec means something different from a per-scoop one.

Composition and the active declaration

The heart of the spec is the composition: the full ingredient list with quantities, and the declared actives per serving with their label claims. This is where elemental content, standardized constituents and overage logic all surface — the spec states what the product delivers and, where relevant, what is input to achieve it. An accurate composition section is the spine of the whole document.

Specifications and limits

Beyond what is in the product, the spec defines acceptable ranges: assay tolerances on the actives, microbial limits, heavy-metal and contaminant limits, physical parameters like weight and disintegration. These are the criteria QA tests finished batches against. They turn the formula from a recipe into a quality standard with pass/fail lines.

Allergens, suitability and claims

A complete spec states the allergen profile, the suitability flags (vegan, vegetarian, gluten-free and so on), and the claims the product carries with their basis. These are derived from the ingredients, which is exactly why generating them from the formula is more reliable than asserting them by hand — a hand-typed allergen line is one missed ingredient away from being wrong.

Packaging, storage and shelf life

The spec defines the packaging, the storage conditions, and the shelf life with its basis in stability data. These connect the product to its real-world handling and to the overage assumptions baked into the composition — the shelf life and the label claim are two ends of the same stability story.

Why it should be generated, not typed

Here is the core argument: almost everything in a spec sheet is derived from the formula — the composition, the actives, the allergens, the suitability, the claims. Typing it into a template by hand introduces transcription errors and, worse, drift: the formula changes and the spec doesn't, so the document no longer describes the product. Generating the spec from the formula keeps it correct by construction and current by default. The spec becomes a view of the formula, not a separate artifact to maintain.

Because specification requirements differ by market and customer, confirm the content needed for your specific products and buyers rather than relying on a general summary.

Where Lemoniq fits

Lemoniq generates the specification from the formula — composition, actives, allergens, suitability, claims and more flowing from the same source — so the spec is correct by construction and never drifts out of sync with the product it describes.

The takeaway

A spec sheet defines what a product is, and its value depends entirely on being accurate and current. Because almost all of it derives from the formula, the reliable way to produce one is to generate it from the formula — not to type it into a template that starts drifting the day the formula changes.

Lemoniq generates accurate, always-current spec sheets straight from the formula. We solve this exact problem. See how it works
