That's B12 deficiency.

I take b12 but maybe I’m still not getting enough?

How much are you taking? 5000~10000mcg per day may not be too much, also there are no side effects or overdose risks.

I think you should do a blood test and ensure you're at least over 500 pg/ml.

It's certainly worth checking B12 levels properly. It's quite hard to be B12 deficient and a common reason to be so is due to being unable to absorb it properly in the digestive system (I think this is quite common with celiac disease, for example). That's why injections are a common approach. I went with sublingual administration instead and it worked very well.

For individuals with certain auto-immune diseases (like rheumatoid arthritis), the medication they're on can also interfere with b12 absorption - such as methotrexate. This is a possible consequence of what you mention regarding absorption digestively. Injections are a solution but are not always accessible in every country - in the UK they are extremely hesitant to permit b12 injections, for whatever reason.

If you're willing to pay for yourself, you can look at e.g. Get A Drip. Or marry a nurse who can do it for you. ;)

I had folate anemia and the injection sorted me right out. Supplements didn't help particularly, perhaps because the root cause is poor absorption from EDS.

It’s a b complex pill. It says 15 mcg. Maybe way too low?

The fact that you're taking that B complex pill tells me someone has also spotted B12 deficiency on you, so my hunch was correct?

Anyway, 15mcg is way too low. You need at least 5000mcg daily. I would buy one of these: https://www.amazon.com/NOW-Methyl-B-12-000-Lozenges/dp/B00BH...

Taking a blood test now and after ingesting all the pills will be better to make sure it is doing something.

Orthostatic hypotension, Postural Orthostatic Tachycardia Syndrome, and other related issues are not always (and usually not) B12 deficiency. These issues are downstream of a number of causes.
