It is not necessary (just take iodised salt which is easily available in the market ). Rest of the various types of suppliment (herbal or natural products) are not essential. You can take them if you are interested with your own discretion. Read about healthy and balanced diet from the internet and understand the concept of nutrition. Follow a disciplined and healthy lifestyle on a regular basis to stay fit and healthy.
