When mixed vigorously with water does anybody else get black flakes in their drink when using 1st Endurance Sports Drink? This is my first time using the product and I got the grape mix. Have mixed numerous other sports drinks in the same bottle without this issue…but have mixed the 1st Endurance 5+ times with the same result.
Any help on what this could be?
I don’t know the answer to this, but I have the grape as well. I stopped using this stuff last year when I started working with a new nutritionist, but I do have some laying around that hasn’t been used in about a year and have noticed these “black flakes” in the powder and was wondering what they were as well .
Interesting…I am wondering if it is a reaction with something in the water that’s creating a particulate?
I also wonder if it is worth a call to first endurance to make sure it is not something harmful…that is the worrier in me speaking.
Its nothing harmful. Because we use only natural flavors and no colors, we have some hygroscopic ingredients that pull in moisture and can change color. Its nothing to worry about.
