Our green tea extract contains a small amount of naturally-occurring caffeine (about 1/20th of the amount you'd find in a cup of coffee). It's unlikely that this small amount of caffeine will be problematic for individuals with heart issues.
However, if you are particularly sensitivity to caffeine, we recommend removing green tea extract from your blend. If you'd like to remove green tea extract from your blend, no problem! Just email your Registered Dietitian at RD@gainful.com
As always, please consult your physician before starting any supplements, including protein powder.
