Passionflower

Also called passion flower, passiflora incarnata, passiflora.

The best price per 500 mg and per month, form by form, across 1 UK retailer, and where to buy it cheapest. A unit for comparing, not advice.

Comparing passionflower

We count the passionflower extract or herb a label states per serving, whatever the pack size or the serving size, so every product sits on one scale. Products that combine passionflower with other ingredients are listed separately, because their price buys more than passionflower extract or herb. 500 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.
