Grape seed extract

Also called grape seed, grapeseed, vitis vinifera, opc.

The best price per 300 mg and per month, form by form, across 1 UK retailer, and where to buy it cheapest. A unit for comparing, not advice.

Comparing grape seed extract

We count the grape seed extract a label states per serving, whatever the pack size or the serving size, so every product sits on one scale. Products that combine grape seed extract with other ingredients are listed separately, because their price buys more than grape seed extract. 300 mg is our unit for comparing prices, not a dose to take: the label’s directions and a pharmacist decide that.

How we work out these prices

We count the weight of extract per serving. Where a label quotes a “whole herb equivalent” (for example “5,000 mg from a 10:1 extract”), we use the actual extract weight. Branded, standardised extracts are compared separately from unbranded ones.
