Q1. Are multivitamins harmful if taken daily?
Not necessarily. But in the case where one's diet is well balanced, the macronutrients do the body some harm. In this case the vitamins A,D E, and K would be harmful.
Q2. Can I take protein powder every day?
Yes, but only if there is a protein deficit in your diet. Whole sources i.e paneer, eggs, and dals should always come first.
Q3. Is it okay to buy supplements online?
Only from website which have been verified. Check for FSSAI (India), FDA registered (USA), and third party tested.
Q4. Can supplements replace food?
Absolutely not. The term supplement mplies an adjunct not a substitute and hence should not be used to replace food.
Deficiency management (confirmed by bloodwork)
During pregnancy
Recovery post-surgery
When dietary restrictions apply (like dairy allergies)
Not really. But they can do damage if misused.
When used properly, supplements are good. Think of them like adding spices to food; with the right amount, they're helpful, but too much will spoil the dish. If you're working a regular job and following a proper diet with good sleep and exercising regularly, then most likely you don’t need all those pills you have in the drawer.
Provided you use them properly, these can be very helpful if you need them due to your health condition or lifestyle. For more information you can visit WellnessZ, as they have 5+ years of experience in this industry.
