This item clearly said that it is 500mg of Resveritrol, yet when I received it, it only has 150 mg of Resveritrol with their own added ingredients and with their ingredients, it adds up to 500mg, but not of Resveritrol which is what I had entered in the search engine. This is the second time misleading information has been placed on Amazon.com; NOW Resveritrol did the same thing when they advertised 250 mg of Resveritrol but when I received it, it had only 10 mg. This is unethical an deceitful. Most probably don't read the labels once they received their product. This has been returned.
