Not sure of the effects...
I really wanted this particular Lokai bracelet (the colors look really great!), so I broke down & bought the Focus bottle. The taste is absolutely horrible! I could not finish a 20 oz bottle of water with the amount of drops in the directions (3, I believe). I tried, but the taste was overwhelming, which it should not have been with 20 oz of water. I never finished the bottle. Complete waste of money. Therefore, I can’t say whether or not it would actually help me focus. Disappointed, as I am looking for something to help me focus and perk me up towards the latter part of a work day.
As for the bracelet , I have had it for about a month & the color is wearing off (I’ve never had problems with any other Lokai bracelet).
