I had surgery about 6 months ago. I have always been low on Vit D. Even before surgery. 

Been taking extra Vit D since surgery and again today I need to increase my dose by adding Thiamine.

Does anyone know why the Doctor would suggest increasing protein as a result of a blood draw?

Will email my nut too.

your prealbumin or albumin levels might have been low - that may be why your surgeon suggested increasing your protein intake.   Mine tend to run low as well, so I'm supposed to try get 80-100 grams of protein a day

Thanks. Just sent a note to my nut lady and I see the surgeon on Friday. 

Are you taking an oil based Vitamin D? If so, that may explain why you continue to run low. Try a dry D3 if you aren't already. I use one by BioTech and have not had any issues since.

They have me on that once a week oil based blue pill

Plus Thiamine and another Vitamin D3 uggh

Even before surgery, the prescription Vitamin D did very little to raise my levels. I think I went from a 9 to a 12...something ridiculous like that. It wasn't until I started the dry D3 that my levels actually improved.

If you need more thiamine you can also try benfotiamine another form of thiamine. I take a prescription vitamin D 50,000 units once a week.

I had low Vit D for over a decade before WLs, and could never get my levels up to more than borderline status. I started using Liquid vitamin D that I buy at the vitamin shoppe and i am fiinally in low end of normal.

I get dry D3 at amazom, 50,000I IU. The bottle -app $20 for 100 capsules lasts me 1.5 years. My numbers are now 60-80.. And I line to keep it that way.
