Iron by Flora. Details:Many healthcare providers recommend taking an iron supplement if you’re low on this essential mineral. But form matters. Some iron capsules aren’t very bioavailable, so you don’t absorb and utilize much of what you take. And most forms of iron are hard on the digestive tract, causing constipation and GI upset. Enter Ferritin+, a plant-based ferritin-iron made with organic peas. Ferritin is a naturally protein-coated form of iron found in legumes that allows for controlled release and efficient absorption, which helps to minimize digestive upset. Our clinical studies have shown that plant-based ferritin iron capsules can effectively increase and maintain healthy iron levels. * Support your energy levels and red blood cell production with Ferritin+.
