As a health and nutrition expert with a focus on dietary supplements, I often get asked about the best forms of certain nutrients, including zinc. When it comes to zinc supplements, it's important to consider bioavailability, which is a measure of how well a substance is absorbed and utilized by the body. Zinc oxide is often used in topical applications due to its anti-inflammatory and wound-healing properties, but it's not the best form for oral consumption because of its low bioavailability. Chelated zinc refers to zinc that has been bonded to an amino acid or other molecule to improve its absorption. Among the chelated forms, zinc gluconate and zinc citrate are considered to be well-absorbed by the body and are commonly recommended. However, zinc orotate stands out as it is a chelated form of zinc that is believed to have even higher bioavailability than other chelated forms. This means it may be more readily absorbed and utilized by the body compared to other zinc supplements. It's also important to note that individual needs and responses to supplements can vary, so what works best for one person might not be the best for another. It's always a good idea to consult with a healthcare provider before starting any new supplement regimen. read more >>
