Ferrous gluconate is available in a liquid form, often used as an alternative to organic ferrous sulfate. One of the benefits of ferrous gluconate is that it provides 75 mg of elemental iron from ferrous fumarate. However, it is important to be aware of potential side effects associated with the use of ferrous fumarate. Additionally, combining ferrous gluconate with Viactiv calcium citrate may enhance the overall absorption of iron and calcium in the body. It’s advisable to consider these aspects when incorporating ferrous gluconate into your dietary regimen, especially if you are also taking Viactiv calcium citrate for added nutritional support.
