Celery seed oil contains a unique ingredient called 3-n-butylphthalide (3nB), which is responsible for its characteristic flavour and odour. Studies have also shown that 3nB supports good, blood circulation by maintaining healthy blood vessels. It also supports in maintaining healthy joints and muscle. Kordel’s Celery Seed contains a standardised amount of 85% 3nB extracted from Celery seed, thus ensuring a correct and consistent amount of active ingredients needed to achieve its effect in each capsule.
