Nature's Bounty Gentle Iron Review

Gentle Iron from Nature's Bounty is a capsule supplement that the page describes as a source of iron for people who want gentle support. The product description says iron is a necessary component of hemoglobin, the oxygen carrier in the blood, and promotes cellular energy utilization. It also states that iron supports normal red blood cell production and is important for women's nutritional health. The page highlights three points: it supports red blood cell production, it is gentle on your stomach, and it contains folic acid and vitamin B-12. Each serving is one capsule, and each container holds 90 servings. The supplement facts list 60 mg of vitamin C as ascorbic acid at 100 percent daily value, 400 mcg of folic acid at 100 percent, 8 mcg of vitamin B-12 as cyanocobalamin at 133 percent, and 28 mg of iron as ferrous bis-glycinate at 156 percent. The other ingredients are vegetable cellulose and gelatin, with less than 2 percent of silica and vegetable magnesium stearate. The label is marked non-GMO, with no artificial color, no artificial flavor, no sugar, no starch, no milk, no lactose, no soy, no gluten, no wheat, no yeast, and no fish, and it is sodium free. Directions say that adults should take one capsule daily, preferably with a meal. The warning advises pregnant or nursing women, people taking any medications, and people with any medical condition to consult a doctor before use. It also says to discontinue use and consult a doctor if any adverse reactions occur, to store at room temperature, and not to use the product if the seal under the cap is broken or missing. The product is manufactured by Nature's Bounty, Inc. in Bohemia, New York. The FAQ advises following the label directions and consulting a doctor or healthcare professional before taking more than the recommended amount.
