Iron Supplements Philippines: Signs of Low Iron, Best Form, and How to Take It
Share
If a blood test shows low iron, an iron supplement taken with vitamin C and away from calcium, coffee and tea is the usual approach. Iron bisglycinate is a gentler form that many people find easier on the stomach than ferrous sulfate.
At BeHealthy: Bronson Iron Bisglycinate 25 mg — ₱1,419 (180 count). Get a CBC first — tiredness alone is not proof of low iron.
Namumutla, hinihingal sa hagdan, laging pagod? Low iron is one of the most common nutrient problems among Filipino women and young children, according to DOH and FNRI nutrition surveys. But the same symptoms have other causes, so the first step is a blood test, not a bottle.

Signs Your Iron May Be Low
Feeling drained even after enough sleep.
A common sign doctors check during a physical exam.
Especially on stairs or light exertion.
Less specific, but common with low iron.
Hemoglobin Levels: When Is It Anemia?
A complete blood count (CBC) measures hemoglobin. The WHO uses these cut-offs for anemia:
| Group | Anemia if hemoglobin is below |
|---|---|
| Adult men | 13 g/dL (130 g/L) |
| Non-pregnant women | 12 g/dL (120 g/L) |
| Pregnant women | 11 g/dL (110 g/L) |
| Children 6–59 months | 11 g/dL (110 g/L) |
Philippine labs often report hemoglobin in g/L — divide by 10 to compare with the g/dL figures above. Your doctor may also check ferritin, which shows your iron stores.
Find the cause. Anemia can come from heavy menstrual periods, bleeding in the stomach or intestines, pregnancy, or conditions unrelated to iron. Adults with anemia should see a doctor rather than self-treat, especially men and women after menopause.
Iron-Rich Filipino Foods
| Food | Iron type | Absorption |
|---|---|---|
| Atay (liver), beef, pork | Heme | High |
| Dilis, tahong, sardinas | Heme | High |
| Malunggay, kangkong, spinach | Non-heme | Lower — pair with vitamin C |
| Munggo, beans, tofu | Non-heme | Lower — pair with vitamin C |
Absorption trick: eat calamansi, tomato, guava or other vitamin C foods in the same meal as plant sources of iron. Save coffee and tea for at least an hour after.
Types of Iron Supplements
| Form | Notes |
|---|---|
| Iron bisglycinate (chelated) | Bound to glycine; often better tolerated on the stomach |
| Ferrous sulfate | Common and inexpensive; stomach upset and constipation are frequent |
| Ferrous fumarate / gluconate | Other common salts with similar side effects |

Frequently Asked Questions
The best iron supplement is one your doctor recommends for your lab results and that you can take consistently. Iron bisglycinate, such as Bronson Iron Bisglycinate 25 mg (₱1,419), is a gentler form many people tolerate better than ferrous sulfate.
Hemoglobin rises gradually, usually over several weeks once iron intake is corrected. Follow your doctor's treatment, eat iron-rich foods with vitamin C, and avoid taking iron with calcium, coffee or tea. A repeat blood test shows whether it is working.
The WHO considers anemia present below 13 g/dL for adult men, 12 g/dL for non-pregnant women and 11 g/dL for pregnant women. Philippine labs often report in g/L, so 120 g/L equals 12 g/dL.
Iron is absorbed best on an empty stomach in the morning with a source of vitamin C. If it upsets your stomach, take it with a small meal instead, and keep it at least two hours away from calcium.
Common side effects are constipation, nausea, stomach upset and dark stools. Gentler forms such as iron bisglycinate may cause fewer stomach problems. Tell your doctor if side effects stop you taking it.
Malunggay contains iron, but it is the non-heme type, which the body absorbs less easily than iron from meat and fish. Eating it with vitamin C foods such as calamansi or tomato helps absorption.
Yes. Iron and vitamin B12 do not interfere with each other, and both support red blood cell formation. Your doctor may test for both if you have anemia.
