Solgar Gentle Iron Review

Solgar Gentle Iron Vegetable Capsules provide an essential mineral that supports energy metabolism and serves as a vital component of hemoglobin. Low iron status affects almost 80% of people, especially women and the elderly. Solgar's patented Gentle Iron formula helps promote energy utilization, improve iron status, form new red blood cells, and help transport oxygen throughout your body. Menstruating women, mothers, and athletes may particularly benefit from this supplement to help them maintain good health and an active lifestyle. While some standard iron supplements cause gastrointestinal irritation and constipating effects, this unique, patented chelated formula (iron bisglycinate chelate) is specifically formulated for enhanced absorption, making it non-constipating and gentle on your stomach and system so you can enjoy the supplement without harsh side effects. Each serving of one vegetable capsule delivers 25 mg of Iron (as iron bisglycinate chelate), which is 139% of the Daily Value. As a dietary supplement for adults, the suggested use is to take one vegetable capsule daily, preferably with a meal or as directed by a healthcare practitioner. The formula is Gluten-Free, Dairy-Free, and Kosher (Solgar's KOF-K certification #K-1250), and it is completely free of gluten, wheat, yeast, sugar, salt, artificial flavors, artificial sweeteners, and artificial colors. It is available in 90 capsule (UPC 033984012493) and 180 capsule (UPC 033984012509) bottle sizes, utilizing US Patent Numbers 6,706,904 and 6,716,814 licensed by Albion International Inc. Warnings indicate that if you are pregnant, nursing, taking any medications, or have any medical condition, you should consult your healthcare practitioner before taking any dietary supplement, and discontinue use if any adverse reactions occur. Accidental overdose of iron-containing products is a leading cause of fatal poisoning in children under 6, so keep this product out of reach of children and store at room temperature. Since 1947, Solgar has committed to The Gold Standard of quality, creating nutritional supplements in small batches through tireless research, responsibly sourced raw materials, USP water filtration, and HEPA air filtration.
