People usually call this Himalayan pink salt. Miners extract it from underground salt reserves. Iron compounds and trace minerals give this salt its pink colour. Pink salt contains small amounts of iron, potassium, and magnesium. But these tiny amounts do not meet your daily nutritional needs. You cannot call pink salt much healthier than regular salt just for these trace minerals.
You can choose pink salt for its unique look, colour, or taste. You must check the label for added iodine if you replace regular salt with pink salt. You might face health issues if you consume non-iodized pink salt regularly without other iodine sources.
