I started taking CurraNZ after suffering with bad hay fever. I read that blackcurrant extract could help reduce hay fever symptoms, and started out taking one a day. I noticed a slight improvement, as well as improvements to my circulation. I decided to up the dose to two capsules, in divided doses and now have more energy during the day. It doesn't completely eliminate the hay fever, and on bad days I take three capsules in divided doses (throughout the day). I have also found I have less aches and pains since taking the capsules and my eyes are less watery. I would recommend these, but I think the optimal dosage is 2-3 capsules daily.
