Vitamin A Overdose: Symptoms, Risks & What to Do

Question
I have been taking a suppliment for hairloss, which has worked fairly well, but extremely gradual, and I am still working towards filling in my bald spot. I have not been feeling terribly well lately, and one of the concerns with this suppliment is it contains lots of vitamin A and Iron. It is a 3 pill a day suppliment, and according to the people who make it 6 pills would be risking overdose. I looked online for the symptoms of vitamin A overdose as follows.

Vitamin A overdose:
Blurred vision, dizziness, ringing in the ears, headache, insomnia, irritability, apathy, stupor, skin rash, nausea, vomitting, diarrhea, hair loss, joint pain, menstrual irregularities, fatigue, liver damage, abnormal bone growth, damage to the nervous system.

I think my vision is a little blurred, but don't know if that isn't just because I am 31, and have experienced mild dizziness which I am not sure if I can attribute to the same. I do have headaches in the morning, but not beyond that. Insomnia is nothing new and apathy started when I turned 30 before I started using this product. Today I noticed nausea which is what prompts my question. I can't be sure if this product is overdosing me on A or Iron. Are there tests to show if ones levels are correct? I don't have insurance. I am on medicare and have a physical with a new doctor in a week. I made the appointment like 4 months ago. Is there a test I should ask for while I'm there, or maybe the medicare could cover this test at the ER? Most of my apathy and depression in life stems from losing hair so I don't want to stop using this product if I don't need to. It has yet to cause increased hairloss which is a sympom of overdose. Maybe there are other nutrients that cause vitamin a to be used more efficiently also?

Answer
stop the vitamin A.... if it goes away in 2 weeks, you can blame it on the medicine.  I doubt if someone would do a vitamin A level in the emer room..... that is a specialty send out test.  

I would check your thyroid tests since you have hair loss, depression/apathy also.

Get with a good primary care doctor to work with them.

There are better hair restoration medicines than Vitamin A which is questionable at best.
