Let me echo the response from above. Getting your iron and/or iron binding labs is really the best way to detect an iron deficiency.
Anemia can be caused by several things, including a few different nutritional deficiencies. And sometimes it’s not the diet, per se, but less absorption of a particular nutrient. For example, B12 deficiency can lead to a type of anemia. A lot of older people have low intrinsic factor and just absorb less B12, even omnivores.
And then, anemia can be due to blood loss. Hence, the labs are necessary. There’s a whole algorithm a physician can go through to rule in or rule out causes of anemia, of which iron deficiency is merely one of them.
And then there’s the symptoms of anemia. Do you feel tired or get tired easily on exertion. (Although there are a hundred different causes for this, too.)
So, try not to worry or predict if you’re getting enough iron until you see the lab results. If you’re not experiencing any symptoms or feeling off, then I wouldn’t worry about it.
So much internet talk these days about nutritional deficiencies. IMO, most problems from diet are dietary excess. These days with modern food and labels, it’s really really hard to develop a true nutritional deficiency unless you’re ill, elderly, or have some kind of specific condition.
Even a college student on a 2 week bender of taco Bell only will accidentally fall ass backwards into the minimum vitamins and amino acids necessary to prevent a nutritional deficiency.
Reference: my brain and 21 years experience as a pharmacist. Trust me, 9 out of 10 people taking vitamin supplements don’t need them and are just making their urine yellow for no reason.
The supplement industry is a $37 billion solution to a problem that doesn’t exist. If we could just reroute that wasted money into covid vaccine distribution, the lives that could be saved would be tremendous, and we’d improve quality of life so much more than supplements. Just my 2 cents.
