ESA and iron enhance surgery outcomes
Use of preoperative erythropoietin-stimulating agents is associated with decreased thrombotic adverse events compared to red blood cell transfusion in surgical patients with anaemia.
Evaluates cardiovascular surgical risks
We aimed to understand how preoperative treatments like erythropoietin-stimulating agents (ESAs) and intravenous (IV) iron influence the risk of blood clots in surgical patients dealing with anaemia.

In our investigation, we found that patients who received ESAs—whether accompanied by IV iron or not—had lower risks of serious post-operative complications, including blood clots, compared to those who were given red blood cell transfusions. Specifically, those treated with ESAs without IV iron showed significant reductions in mortality and the occurrence of venous thromboembolic events.

Interestingly, when IV iron was combined with ESAs, it appeared to further enhance outcomes, notably improving survival rates. Our results suggest that combining these treatments might yield benefits for patients undergoing surgery, reflected in higher haemoglobin levels and fewer complications compared to traditional blood transfusions.

Iron's unclear role in DVT
May-Thurner Syndrome: An Unusual Case of Unilateral Severe Deep Vein Thrombosis in a Middle-Aged Women.
Limited effectiveness of iron therapy
We explored a 50-year-old woman who came to us with noticeable swelling and pain in her left leg lasting ten days. Upon evaluation, we found that she had deep vein thrombosis (DVT) associated with May-Thurner Syndrome (MTS), where a vein is compressed by an artery. Initially, her blood tests showed normocytic anemia, yet the tests for blood clotting disorders returned normal.

Treatment began with anticoagulation therapy using enoxaparin, coupled with iron supplementation. While iron is typically known for helping with anemia, its specific effect on blood clot resolution in this case remains unclear. Our patient's initial treatments were expanded to include catheter-directed thrombolysis to dissolve the clot, followed by a procedure to relieve venous compression.

We observed significant success in reducing the thrombus burden and restoring blood flow post-stenting. However, we noted that the role of iron supplementation alone in treating the blood clot is ambiguous when combined with other therapies. Thus, while iron is essential for overall health and could play a supportive role, its independent effectiveness against DVT is undetermined in this scenario.

Improved energy levels
I have always had low iron levels in my blood, affecting my health with constant weakness and fatigue. Headaches and low blood pressure plagued me. After taking this in the morning, waking up became easier, and I fell asleep more quickly at night. My weakness vanished, and my blood pressure normalised. I recommend it to everyone.

Restored hemoglobin levels
This supplement helped me raise my hemoglobin from 80 to 120. I am immensely grateful to its manufacturers. I took two packs, one tablet with meals daily. Now, I no longer experience dizziness or weakness which plagued me due to low hemoglobin since childhood, following a major blood loss from an operation and frequent nosebleeds. Wishing everyone good health and happiness!

Felt less fatigued
I have suffered from low blood iron for a long time, causing low hemoglobin and ferritin, leading to fatigue and lethargy. When my iron levels dropped further, I suffered headaches and low blood pressure. Diets didn’t help. After several purchases here, I finally noticed a decrease in fatigue after a few weeks. My hemoglobin rose to 134, and I feel significantly better.

No side effects experienced
I purchased this supplement for my father after significant blood loss and surgery. Unlike other iron supplements that caused gastrointestinal issues, this one has not. It effectively resolves the iron deficiency without compromising quality of life. I appreciate its effectiveness!

Improved health signs
Iron is crucial for the human body as it helps supply oxygen to tissues. Without it, I experienced pale skin, weak hair, and brittle nails. I've been taking one tablet daily, and my health has noticeably improved, causing less fatigue and restoring my sleep pattern. I highly recommend it if you find this review helpful.
