Iron tablets and vitamins?


Hello Dr.
Hong: I have been diagnosed with iron deficiency anemia, and my doctor has prescribed iron chewable tablets of 100mg (two tablets a day).
Can I purchase vitamin C and B-complex vitamins on my own to take alongside to enhance iron absorption? If so, how much vitamin C and B-complex should I take daily for it to be effective?

Zeng, 20~29 year old female. Ask Date: 2019/08/23

Dr. Hong Kunyi reply Pharmacology


Hello, Miss: It is acceptable to take iron supplements along with an appropriate amount of vitamin C and B vitamins, as the dosages vary among manufacturers.
As long as you follow the recommended dosage on the packaging, it should be fine.
Vitamin C and B vitamins are water-soluble vitamins, and any excess intake will be excreted through urine and will not accumulate in the body.
However, please be reminded of the following precautions when taking iron supplements: 1.
Do not consume tea simultaneously with iron supplements.
2.
Avoid dairy products when taking iron supplements for blood replenishment.
3.
Iron supplements should not be taken with grains (such as corn, barley, wheat, and sorghum).
4.
Iron supplements should not be taken with calcium tablets or certain types of antibiotics (such as tetracyclines).
These are some recommendations to keep in mind.
Wishing you good health and well-being.

More Info


Yes, you can take Vitamin C and B complex vitamins alongside your iron supplements to enhance iron absorption. Iron absorption can be significantly improved by Vitamin C, which helps convert iron into a more absorbable form in the intestines. This is particularly beneficial for individuals with iron deficiency anemia, as you have been diagnosed.


Vitamin C and Iron Absorption
Vitamin C (ascorbic acid) is known to increase the bioavailability of non-heme iron, which is the type of iron found in plant-based foods and supplements. When taken together, Vitamin C can help reduce ferric iron (Fe3+) to ferrous iron (Fe2+), which is more easily absorbed by the body. A common recommendation is to take about 100-200 mg of Vitamin C with your iron supplement. This amount is generally considered effective and safe for enhancing iron absorption.


B Complex Vitamins
The B vitamins, particularly B12 and folate (B9), play a crucial role in the production of red blood cells. While they do not directly enhance iron absorption, they are essential for overall hematopoiesis (the formation of blood cells). If you are considering taking a B complex supplement, a standard dose would typically provide around 50-100% of the daily value for each B vitamin. However, it's important to note that B vitamins are water-soluble, meaning that excess amounts are usually excreted through urine, reducing the risk of toxicity.


Dosage Recommendations
1. Vitamin C: Aim for 100-200 mg daily, taken with your iron supplement. This can be in the form of a separate Vitamin C tablet or a multivitamin that includes Vitamin C.


2. B Complex: A standard B complex supplement usually contains a range of B vitamins, and taking one tablet daily should suffice. Ensure that it contains adequate amounts of B12 and folate, especially if you are at risk for deficiencies.


Important Considerations
While combining these supplements can be beneficial, there are some important considerations to keep in mind:
- Timing: Iron supplements are best absorbed on an empty stomach, but if you experience gastrointestinal discomfort, you may take them with food. If you take Vitamin C with your iron, it can be taken at the same time or shortly before/after.

- Avoid Certain Foods: When taking iron supplements, avoid consuming dairy products, tea, coffee, and high-fiber foods at the same time, as these can inhibit iron absorption.

- Consult Your Doctor: Always consult with your healthcare provider before starting any new supplements, especially if you are already on medication or have other health conditions. They can provide personalized recommendations based on your specific health needs.


Conclusion
In summary, taking Vitamin C and B complex vitamins with your iron supplements can be beneficial for enhancing iron absorption and supporting overall blood health. Stick to the recommended dosages, and be mindful of timing and dietary interactions to maximize the effectiveness of your supplements. Always keep your healthcare provider informed about any changes in your supplement regimen.
