Study

Commissioned by Italian producer of plant extracts Indena [indena.com], researchers gave 38 subjects with slightly elevated blood pressure a placebo for 16 weeks and 40 comparable subjects a supplement that provided 300 milligrams of Grape Seed Extract daily.

The subjects took a capsule with 150 milligrams of Grape Seed Extract just before breakfast and a capsule with 150 milligrams just before lunch.

The researchers used an extract from Indena, Enovita.
