Misleading labeling IMO.

I was looking for a higher dose than the standard 2,000 FU level. So when I came to the DaVinci offering I thought it was 20,000FU in two capsules, thus 10,000FU per capsule. Perfect. There are studies reporting 10,800FU gives much better results than the standard recommended dose. Yes their prices are higher but obviously you are getting a larger dose per capsule. I figured it was more bioavailable due to the NSP-2 brand formulation. After I ordered I wondered why it had a "FU /g "rather than the normal "FU" ?? Most sellers of Nattokinase only have "FU" after the potency. I researched on Google and found that very few sellers list it using so many FU per gram. Obviously a marketing tool to give the impression you are getting a higher dose supplement. So in reality each capsule of DaVinci Nattokinase PLUS only has 1,500 FU of Nattokinase. Yes upon reading the small print on the side of the bottle states clearly 2 capsules contain 20,000 fibrin units (FU) per gram. I rarely even read the side of the bottle. The back label has everything I need to know. This must confuse many people as I read many reviews online saying they were happy to find a Nattokinase at a higher dose. When in reality it is a smaller dose. I am sure Davinci Labs makes great quality products but in my opinion they should label using the standard potency units most of the industry uses so as to not confuse buyers. You have wasted my money. I take enough pills already and don't want to take another 7 capsules everyday just to get the Natto I want. I will buy Swanson Nattozimes.
