Best place to buy genuine supplements online in India?

ive been reading a lot about vitamin d3, zinc, and omega 3 supplements on this sub and want to start. but theres so many options on amazon and other sites and i keep seeing comments about fake products and wrong expiry dates. where do you guys buy your supplements from? any platform that you trust for getting authentic products? budget friendly options preferred because i dont want to spend 2000 on a bottle of fish oil capsules lol
