Vitamin and mineral supplement contributing to the maintenance of good health. The niacinamide, thiamine, riboflavin, pantothenic acid and pyridoxine contained in the ampoules contribute to the maintenance of good health, and the added iron provides the optimal recommended daily allowance (RDA). Multi-Vit + Iron also contains vitamin B12 and liver extract.Many conditions either require the intake of extra iron, or can hinder absorption of the iron. Some of these conditions are: various forms of anemia, Crohn?s disease, cystic fibrosis, depression, pregnancy, lactation, female infertility, fatigue, insomnia, poor growth and development, declining athletic performance, menorrhagia, lack of appetite, restless leg syndrome, weak immune system, history of canker sores amongst other symptoms. Iron is an essential mineral for humans to maintain normal physiology. It is a component of proteins involved in oxygen transport, as well as a regulator of cell growth and differentiation. A deficiency of iron limits oxygen delivery to cells, resulting in fatigue, and decreased immunity. Almost two-thirds of iron in the body is bound to hemoglobin, the protein in red blood cells that carries oxygen to the tissues. There are two forms of supplemental iron available, non-heme iron and heme iron. Some of the non-heme or elemental iron, like ferrous sulfate, ferrous fumarate and ferrous succinate, is poorly absorbed, gastric pH dependent and can cause nausea and constipation, unlike plant-based ferrous gluconate. Heme iron is derived from liver extract and is the better-absorbed and utilized form, which does not cause nausea or constipation. Heme iron is already bound to the oxygen-binding protein thus is easier assimilated by the body with up to approximately 20X greater absorption than the non-heme iron. Heme iron helps to build a person?s blood much faster and maintain iron stores over the long term. Iron needs many co-factors like vitamin C and B-vitamins, for its utilization and absorption. Vitamin C improves non-heme iron absorption and can counteract the effects of substances, which inhibit its absorption, like polyphenol components in teas and wine. The lack of certain B-vitamins can cause various forms of anemia, thus adding vitamin B12 to the mix can help to prevent this, along with vitamin B2 (riboflavin) which can improve the body?s response to an iron supplement in anemia cases. Bio Lonreco Inc.?s Multi-vit + Iron is composed of elemental iron, as ferrous gluconate from natural vegetable source, with supporting B-vitamins for absorption, and beef liver to give a supply of heme iron. It has rapid absorption to provide a much needed energy boost, due to the liquid format, and it is also non-constipating and does not cause any gastric distress.
