Great product but stains teeth
I love that this products as it has really nice ingredients. I use it not only for extra energy but with B complex to target stress. The only very important warning they left off the label that it stains teeth very strongly when used as according to label. I swirled it as recommended and after some time my teeth got dark grey which i could only remove with teeth whitener (mix of baking soda and 3% hydrogenperoxide). So now i swallow it immediately and drink water to rinse my mouth.
