Cold fingers and hands (as well as toes and feet) and reduce Lethargy

hi, Thanks to all your efforts and useful information,
i have a thalassemia minor and suffer lack of concentration in planning everyday tasks and confusion also  often  my fingers and toes are cold.
I have some question:
1-   Please introduce me some best supplements for improving concentration (now I consume Neurozan VITABIOTICS)
2-   If I need Folate (B9), can you guide me about amount of consumption and good supplements that suitable for vegetarians?
3-   Also please advise me some recommendations that can improve my concentration and reduce Lethargy.
 Thank you so much and the result of my last blood test is shown in below:

All very commonly reported issues with thal minor.

Your vitamin D is low. 30 is the minimum "normal" level, but thal minors should strive to get the level above 50. Once weekly dosing with high potency capsules, 50,000-60,000 once weekly may be needed to raise the level. Natural vitamin E (if it's in gel caps, you can poke a tiny hole in the capsule with a pin and squeeze out the vitamin E). 400 IU daily. This will help improve the circulation, while providing a top antioxidant. Vitamin C, 500-1000 mg daily will also improve the condition of the tiny blood vessels, making it easier for blood to flow to the extremities. 2 mg L-methylfolate along with 1000-25000 mcg of sublingual vitamin B-12 which dissolves under the tongue. If tiredness persists, take l-carnitine tablets, as well. Make sure you get some exercise to help improve your circulation.


If you want to send me links to supplement descriptions, I can take a look and see if they are appropriate, keeping the need for veg products in mind (I do the same for myself).
