Science & Research

Iron bis-glycinate is a chelated form selected for absorption and tolerability. Vitamin C supports non-heme iron uptake and is commonly paired in clinical repletion protocols.

Frequently asked questions

OptiFerin-C vs Iron-C—what is the difference?

Will this cause constipation?

Bis-glycinate forms are often better tolerated than ferrous sulfate. If GI upset occurs, discuss dose and timing with your clinician.

Can I take this with my multivitamin?

Review total iron from all supplements to avoid excessive intake unless directed by your practitioner.

How long until ferritin improves?

Repletion timelines vary. Follow-up labs typically guide duration and dose.

How long does one bottle last?

At one capsule daily, a 60-capsule bottle lasts two months.
