EFVC 1000 Sugar Free Orange Effervescent Tablet contains a high amount of vitamin C from amla, along with added vitamin C and zinc. These nutrients are known to support immune function, act as antioxidants, and help in collagen formation. Because the vitamin C dose is much higher than the daily requirement, this product should not be taken routinely. It should be used only if a doctor advises it for a specific medical condition. Using this supplement without proper guidance or in very high doses may lead to side effects in some individuals.
