Hello there. I can understand your concern. Though nutritional supplements are good and are prescribed to many patients from time to time but there is no alternative to natural things. Cap. Revital H is good and is to be taken once a day after food but i would also suggest you to have more greens, vegetables and fruits. Alternatives to revital H would be cap. Absolut 3g or tab. Glutanase. They are all pretty much the same only the number of contents and the strength differ. Best regards. Dr. Anil kumar jain.
