Dear friends,
This is Madhu, 35 year female, writing from India. Since, 3 months I was having the following symptoms.
1.Severe tiredness
2.Mental confusion
3.Burning sensations in the palms and toes
4.Occasional muscle pain
I have consulted a general physician/neurologist/endocrinologist and was found to be negative for diabetes, thyroid issues. Total protein(normal), ANCA(negative), ESR(normal), ANA(negative), anti ds DNA(negative) and CRP(negative). Nerve conduction study was also normal.

In the meantime, thanks to this forum, I was taking vit B12(1500 microgram) supplementation. I did undergo the vit B12 and vit D tests voluntarily(doctor didn't order) and the results were below.
Vit D 25-Hydroxy serum- 13.2 nmol/litre
Vit B12-537 pg/ml(may not be a true value as I was on B12-1500 microgram supplementation until the previous day of the test.

Currently(just started), I am taking natural factors Vit B12 5 mg(batural factors) in empty stomach in the morning(neurologist prescribed a multivitamin capsule which has B12 1500 microgram at night after dinner-i didn't follow his recommendation, thank to the information from this great forum) and Vit D(cholecalciferol 60, 000 IU once in a week for 8 weeks).

My request to the fellow friends here for the following
1. Am I doing a right thing?
2.Do any of you recommend any additional supplementation such as Benfotiamine/alpha lipoic acid etc to start.
3.Do you recommend any additional tests?

In India, I am having very limited access to these supplements. I did get the vit B12 from natural factors with lots of difficulties.

Please help.

Thanks in advance
Madhu
