I have been using the 500mg now for a couple of weeks and have noticed a vast improvement in my focus and energy levels,I can honestly say I have never been a morning person but now I am up early walking my dog before work in the best mood ever my partner can't believe the change,I have also had an improvement with my arthritis and insomnia I have slept right through the night since taking the oil. Now for the shocker I have been using this on my dog ..please note Sarah at blessed has not recommended this as their product is not for animal use ..my akita has fear aggression and has severe anxiety she also has has ACL surgery to both legs and spends her days suffering with joint paint , I have been giving her 3 drops a day and she is a lot calmer and more relaxed and she is now on two 40 min walks per day where before she could only manage 10 mins she also had acid reflux every morning and was sick now this has stopped so this is proof enough for me personally how good this product is so thank you!
