Compare every Parsley product across UK retailers on Suppio, ranked by true value - price per active dose, not pack size. Prices refreshed daily.
Herb used as a diuretic and source of vitamins
We rank Parsley by price per gram of active ingredient - not by pack size - so a bigger tub with a worse price per dose can't outrank a smaller one that's actually cheaper.
Parsley is a common culinary herb. In supplement form, it is used as a source of vitamins and as a diuretic, which is a substance that helps the body get rid of excess water and salt through urine.
It is primarily taken to support the body's fluid balance and to provide essential nutrients. Because it acts as a diuretic, it is often used by people looking to reduce water retention.
The plant is harvested and then dried using controlled heat to preserve its nutrients. Once dried, the leaves are ground into a fine powder, which is then either packed into capsules or sold as a loose powder.
Parsley supplements are generally mid-range in price. This is because while the plant is easy to grow in large quantities, the cost of drying and processing the leaves into a concentrated powder adds to the final price.
