My only concern is the dosage at 5 capsules daily

Nothing to report yet as it's my very 1st purchase - I'm commenting to point out the dosage advertised is incorrect: it's not 5,000mg as advertised - it's 500mg. disappointed that there's no usage info except dosage of 6-10 tablets which was also incorrectly advertised as 2 tablets daily
