Iron is an essential element for blood production. About 70% of your body’s iron is found in hemoglobin, which is essential for transferring oxygen in your blood from your lungs to your tissues. If you struggle with any kind of inflammation, this production can be reduced, and being low on iron phosphate means your body will struggle to supply oxygen to your cells. Deficiency symptoms can include fatigue, low to moderate fevers, a weak immune system, a red face, nosebleeds, sore throats, anemia, and blood problems. Luckily, iron phosphate can easily be supplemented with homeopathic cell salt #4 Ferrum Phos.
