FeRiva 21/7® is enhanced with complementary nutrients

21 DOSES: One red tablet, once-daily, replenishes iron and more
Iron (as Ferrous asparto glycinate [Sumalate®]) 75mg Highly absorbed iron that can be taken with or without food1-8
Vitamin C (as Ascorbic acid) 175mg Pushes iron from GI tract into intestine’s cells9-11
Succinic acid 150mg Helps transport iron from the intestine’s cells into the bloodstream12,13
Folic acid……………..400mcg
1mg Fosters red blood cell development with traditional folic acid + a bioactive form that helps some women more2,15-17
Vitamin B12 (as Cyanocobalamin) 12mcg Essential for red blood cell formation2,17
Zinc (as Zinc bisglycinate) 10mg Zinc deficiency often accompanies iron deficiency18,19
7 DOSES: To allow cells to regenerate and restore absorption potential, purple tablets are iron-free

*FeRiva 21/7® contains non-branded L-methylfolate vs. ingredients supplied by branded manufacturers.
The L-methylfolate [(6S)-N5-methyltetrahydrofolic acid calcium salt] in FeRiva 21/7® is less than 1.0% D-isomer.
PRECAUTIONS: Folic acid alone is improper therapy in the treatment of pernicious anemia and other megaloblastic anemias where Vitamin B12 is deficient. Folic acid in doses above 1.0 mg daily may obscure pernicious anemia in that hematologic remission can occur while neurological manifestations progress. While prescribing this nutritional supplement for pregnant women, nursing mothers or for women prior to conception, their medical condition and other drugs, herbs and/or supplements consumption should be considered.


21/7 dosing improves absorption and tolerability


21 days active iron therapy replenishes
iron during the time intestinal cells are most able to absorb iron13,14


7 days iron-free allows cells to regenerate
and replace those blocked from absorbing iron optimally13-15
7 days iron-holiday helps prevent side effects
