Hi Vandana,
First of all, thank you so much for your positive review!
Additionally, regarding your question about the capsules, we wish to notify you that the outer covering doesn't specifically contain any nutritional value. They are made from cellulose and are known as HPMC capsules (Hydroxypropyl Methylcellulose).
You can consume the capsule with the outer covering however if you want you can just consume the content inside the capsule and rest assured, it won't lose its efficacy by anyway.
Though just make sure you are having the product regularly along with a proper diet and lifestyle and you should be able to see the results within 3-6 months.
