Natural energy supplements for women: iron and B12
Search for a natural energy supplement for women and two nutrients come up again and again: iron and vitamin B12. Both are involved in the body's normal energy-yielding metabolism and in forming red blood cells, which is why they sit at the center of this topic.
Food first
Iron and B12 are both found in animal foods. Beef liver is one of the most concentrated food sources of each, which is why it appears in discussions of energy as well as organ supplements generally. Red meat, shellfish and eggs also carry both. Plant foods can provide iron, in a different form, and B12 is the harder of the two to get without animal foods or fortified products.
Where organ supplements fit
An organ supplement is dried organ in a capsule. A liver capsule therefore contains the iron and B12 that were in the liver, in food amounts that follow the serving size. Our overview of organ supplements for women explains how servings and blends differ, and the label of any specific product lists what a serving provides.
Reading an energy label
- Iron listed per serving, and whether it is elemental iron.
- B12 amount per serving, usually in mcg.
- Whether the iron and B12 come from food ingredients or are added separately.
- Vitamin A, if liver is an ingredient, counted with your other supplements.
The caution that matters
Iron is not a more-is-better nutrient, and feeling tired has many causes that a supplement does not address. If tiredness persists, that is a reason to see a qualified professional and get properly checked, not to keep adding products. Do not start an iron supplement on a guess, and keep total iron from all sources in view.
