Nitrate (beetroot extract)

Nitrate (beetroot extract) suppliers and sourcing guide

Beetroot extract is a concentrate of red beet (Beta vulgaris) root, sold for its naturally high nitrate content. Beets are washed, pressed or extracted with water, and the juice is concentrated and spray-dried, sometimes on a carrier such as maltodextrin; some suppliers further concentrate the nitrate fraction. Brands buy it as a deep red powder standardized to a stated nitrate percentage, or as whole beet root powder with a lower, natural nitrate level.

Forms and grades of nitrate (beetroot extract)

Suppliers sell different products under the same name. Specify the one you need.

  • Nitrate-standardized extract

    Beet juice or extract powder standardized to a stated nitrate content, often several percent, for capsules, shots and drink mixes.

  • Whole beet root powder

    Dried, milled beet root with natural, variable nitrate and more fiber, also used for color.

  • Juice concentrate

    Liquid beet juice concentrate with a stated Brix and nitrate level, for ready-to-drink products.

  • Organic grades

    Powders and concentrates from certified organic beets, often without added carrier.

What to check on the COA

Compare each result with your own specification when the lot arrives.

Nitrate and nitrite
Nitrate and nitrite by ion chromatography or HPLC; nitrate is the standardization target and nitrite should be low.
Betanin or color value
Betanin by spectrophotometry or HPLC, which tracks color and shows heat damage.
Moisture and water activity
Loss on drying and water activity; beet powders are sugary and cake easily.
Heavy metals
Lead, cadmium, arsenic and mercury by ICP-MS; root crops can take up cadmium and lead from soil.
Pesticides
Multi-residue pesticide screen by LC-MS/MS and GC-MS.
Microbiology
Total plate count, yeast and mold, coliforms, and absence of Salmonella and E. coli.

Storage, lots and expiry

Storage and shelf life

Keep beetroot extract in sealed, moisture-proof, light-proof packaging in a cool, dry place; it is hygroscopic and its red color fades with light, heat and air. Liquid concentrate should be kept closed and chilled if the supplier specifies. Shelf life is set by the supplier's specification, with retest of nitrate, color and micro for older stock.

Lots and expiry dates

Record the nitrate result for each lot and dose from it, since beet nitrate varies widely with variety, soil, fertilizer and season. Note carrier content, which dilutes nitrate in some grades.

Regulatory status

Facts from regulators and standards bodies, each linked to its source.

  • 21 CFR 73.40 lists dehydrated beets (beet powder), a dark red powder prepared by dehydrating edible beets, as a color additive that may be used for coloring foods generally in amounts consistent with good manufacturing practice, with a lead limit of not more than 10 parts per million. This listing covers beet powder used for color, not nitrate-standardized extracts as such.

  • Health Canada's Natural Health Products Ingredients Database lists beet root powder (Beta vulgaris root, powdered) as an approved non-medicinal ingredient with the allowed purpose of colour additive.
