Not all iron supplements are created equal. 🩸
First things first… not everyone needs to be taking iron. Too much isn’t better and this is one supplement where the right dose, for the right person, really matters.
But if you do need it, the form makes a big difference.
Many people are given iron as ferrous fumarate… and then struggle with:
• Abdominal pain
• Nausea
• Constipation
Sound familiar?
A gentler option is iron bisglycinate. It’s bound to the amino acid glycine, which helps it pass through the gut more comfortably and improves absorption. In fact, it’s often 2–3 times better absorbed, meaning you get more benefit with fewer side effects.
Then there’s vitamin C. 🍊
It acts as an antioxidant, donating an electron to iron and helping convert it into a form your body can absorb more efficiently. Think of it as the key that helps unlock the door.
So who might actually need to supplement?
• Menstruating women, especially with heavy periods
• Vegans and vegetarians
• Older adults
• Those taking stomach acid inhibitors
The best way to know? Blood testing.
In particular, looking at your ferritin levels, which reflect your iron stores. Optimally, we’re aiming around 90 ng/ml for good energy, recovery and overall function.
Right supplement. Right form. Right person.
That’s where the real difference is made.
