Nature Made Iron 65 mg Review

Nature Made Iron 65 mg Tablets (325 mg Ferrous Sulfate) is presented on this page as a tablet product that provides 65 mg of iron per tablet, delivered as 325 mg of ferrous sulfate. The page describes one daily tablet as providing iron that is vital for red blood cell formation and that supports healthy cognitive function. The product is specially positioned for iron deficiency, and the page states that one in 10 US adult premenopausal women ages 15 to 49 are deficient in iron. The benefits section explains that iron is an essential part of hemoglobin, the protein that enables red blood cells to carry oxygen throughout the body. It notes that iron is an essential nutrient for women in their reproductive years, and it states that adults with iron deficiency should take one tablet per day. The page lists key benefit categories for heart and brain health. The product facts state that the tablet is sourced from high quality ingredients and that iron can be found in red meat. The page also notes that the product is USP verified, meaning USP has tested and verified ingredients, potency and the manufacturing process. The ingredients section highlights that the tablet is gluten free, contains no artificial flavors and contains no synthetic dyes. The label callout lists the amount per serving as 65 mg iron (325 mg ferrous sulfate) and shows item number 2612. The nutrient shortfalls section explains that about 5% of Americans have inadequate intakes of iron. It describes heme iron from sources such as liver, oysters, shellfish, lean red meat, poultry and fish, and non-heme iron from sources such as dried beans, dried fruits, blackstrap molasses, dark green leafy vegetables, prune juice, iron fortified cereals and lima beans. The page notes that non-heme iron is not absorbed as well as heme iron. The product is designed for people with low levels of iron or iron deficiency. The suggested use is one tablet daily with water and a meal. The dosage section includes warnings that accidental overdose of iron-containing products is a leading cause of fatal poisoning in children under 6, that the product should be kept out of reach of children, and that pregnant or nursing people or those taking medication should consult a physician before use. The FAQ states that iron toxicity is rare because absorption is regulated and decreases when iron stores are full. It also notes that taking iron with a meal instead of on an empty stomach can help relieve gastrointestinal effects that may occur at doses above 45 mg per day. The page states that the product is discontinued and no longer available, and that the count is 180 tablets with a one-time purchase price of $10.59. The product is rated 4.6 out of 5 from 51 reviews.
