Hematinic formulas provide the nutrients needed for creating new red blood cells. Studies indicate that a hematinic formula using a combination of folate, vitamin B12, and iron is superior to a formula using any one of these nutrients alone. Each of these nutrients is dependent upon the other for proper red blood cell formation. Ferrasorb combines the two active forms of vitamin B12 – adenosylcobalamin and methylcobalamin – and the two active forms of folate – folinic acid and L-5-methyltetrahydrofolate, with well-absorbed iron picolinate – for a superior hematinic product.

Individuals who might benefit from a hematinic formula include those with a greater need for iron, those who tend to lose iron chronically, and those who do not absorb iron well. Such individuals include teenage girls, pregnant women, women of childbearing age (particularly if they have heavy menses), individuals with malabsorption syndromes (Crohn's disease or Celiac disease), elderly patients with low hydrochloric acid secretion, and individuals with poor kidney function.

An iron deficiency can manifest as weakness, fatigue, shortness of breath on exertion, dizziness, tinnitus, spots before the eyes, drowsiness, irritability, infrequent menses, and loss of libido.

What is picolinic acid? Picolinic acid is a metabolite of tryptophan, is similar to niacin, and is naturally produced in the pancreas. Picolinic acid can bind to minerals in the gastrointestinal (GI) tract and facilitate their absorption into the bloodstream. Conventional iron supplementation, including forms such as ferrous sulfate, can cause GI side effects – including nausea, vomiting, constipation, diarrhea, and dark-colored stools – because these conventional forms are poorly absorbed.
