Both liquid zinc and zinc tablets are zinc supplements, but they are different in their dosage forms. Liquid zinc is a liquid preparation, which is easier to absorb and more rapidly acting than solid zinc. Liquid zinc is more suitable for the elderly and children in particular, as it is more difficult for younger babies to take tablets orally, so it is recommended that children take liquid zinc such as zinc gluconate for zinc supplementation, while the elderly are also more suitable for oral liquid zinc due to slow gastrointestinal motility and slow absorption. However, in many cases it is more important to supplement zinc through diet, paying attention to nutritional balance. You can eat animal offal or shellfish, and plants such as peanuts are also foods with high zinc content.
