What the Evidence Says

✨ AI-generated · Qwen 3.6 · methodology

Ferrochel and Vitamin C are supported by strong evidence for improving iron absorption and treating deficiency. Folate and Vitamin B12 provide moderate evidence for supporting red blood cell production. L-Histidine's role in this specific complex has more limited clinical documentation.
