Hi Joseph, When I was diagnosed with DLBCL I requested a consult with a dietitian to look at the supplements that I had been taking. She dame all of them to be fine to keep taking. Those include a multivitamin, turmeric, Optiferin-C, B6 with magnesium, and omega-3. I have not gotten on B12 for fatigue, but I know plenty of people who have and it does help. I would say check with a dietitian and your oncologist just to be sure.

Hello Joseph, my dx DLBCL I had a vitamin D deficiency and a vitamin K deficiency. I was advised to take a supplement of both. I’ve never had any experience of blood thinning at all, however, that doesn’t mean that it will be the same for you so I definitely communicate with your oncologist.
Also for the fatigue, I started taking a supplement of vitamin B 12 which made a huge difference. I hope this helps.

JosephSikora,
Hi and welcome to the site. Everyone on here is so kind, supportive and helpful. I have/had DLBCL stage IV and had treatments of RCHOP chemo. I've been in remission for 3 1/2years. I take multi vitamin, B12, D3 with calcium, C, Balance of Nature. I hope this helps answer your question. Kelly

No I was given a print out and went to the vitamin cottage.

Thank you, were they prescribed by your Doctor.
