What vitamin/herbal suppliment can I use to increase oxygen flow to brain?
 

I dont have lung problems/asthma/allergies etc. but i've been having a hard time feeling like I am getting enough oxygen. I am constantly trying to get a full breath and yawning constantly trying to feel satiated with my breathing but I havent been able to. I exercise regularly and eat healthy. Any ideas?:)

Have you been checked for anemia? Also, stress can cause shallow breathing.

Yoga and meditation also help with teaching normal breathing.

I would get checked out before taking iron however. I see in your profile, you have B12 deficiency? This should be checked out to see if you have low iron as well. If you do not have adequate B12 now, your red cells will become large and this is called macrocytic anemia. These larger cells don't get thru tiny capillaries easily.

vinpocetine is one, but it is not exactly the safest.

Thanks everyone for the responses :) I dont have a B12 deficiency although I thought I did my neurologist confirmed that I didnt. I am having some neurological issues they are still trying to find out what it is but one of my main issues is feeling light headed/dizzy and like im not getting enough oxygen. I was hoping there was some sort of vitamin that helped enhance the oxygen flow until they find out whats really wrong.

Do you have a recent B12 reading?
 

Sorry to say this, but most doctors are not well-versed nutritionally, especially about B12 levels; many are still using old, outdated levels with very low minimums that they consider to be part of the normal range.

A lot of the old lab ranges indicate values of 185-200 as bottom of normal range; I don't think anyone here would say that was adequate. (At least 500 or so would be minimal "normal" levels, and that value is used in most European ranges and in Japan. Most of us would rather see much higher levels; B12 has no known toxicity level.)

A better indicator of B12 deficiency would be results from homocysteine and methylomaic acia (MMA) testing--but many docs don't have knowledge of this, either.
