My son (22) had a colectomy, his colon was removed and subsequent J Pouch etc. He recently is very fatigue, weightloss etc could this be a b12 defiec?

My son (22) had a colectomy, his colon was removed and subsequent J Pouch etc. He recently is very fatigue, weightloss etc could this be a b12 defiec?

Unlikely: B12 absorption and the intrinsic factor that are involved in the process are all part of the small intestine function. The colon is more of a storage area, water retriever than anything else, so loss doesn't often give significant problems. Fatigue is a good reason for an office evaluation. ...Read more

How much of B12 supplement can my body absorb per day? Does taking more 5000 mcg in 5 times (in 2hours gap) mean more absorption than 1000mcg one time?

How much of B12 supplement can my body absorb per day? Does taking more 5000 mcg in 5 times (in 2hours gap) mean more absorption than 1000mcg one time?

Sublingual B12: Is best. Get the kind that melts under your tongue and with folate (folic acid) if possible. 500 to 1000 mcg is a common dose. If you swallow the B12 you will get much lest benefit because it has to go through your GI system. Peace and good health. I see you struggle w/fatigue. You may find the MicroNutrient Test from Spectracell lab in Tx helpful. ...Read more

Does fat content increase the absorption of vitamin D2, or this only apply to D3? Does vitamin D2 interact with B12? How do I optimize D2 absorption?

Does fat content increase the absorption of vitamin D2, or this only apply to D3? Does vitamin D2 interact with B12? How do I optimize D2 absorption?

Optimizing D absorpt: Vit D3 is superior to D2. Both are fat soluble. Absorption is enhanced with food and fat. To optimize effects, be sure you have vit K2 going in as well -- approx 100 mcg of vit K2 for every 1000 iu of D3 is appropriate. ...Read more

Any way to cure the intrinsic factor in the digestion system for the absorption of vitamin B12 complex?

Any way to cure the intrinsic factor in the digestion system for the absorption of vitamin B12 complex?

Yes and No: Most intrinsic factor deficiencies are due to either partial gastrectomy or auto-antibodies that attacked the parietal cells of the stomach. In both, the damage may already be done. However, you can get B12 in the body in a few ways. 1) take a higher dose of B12 starting at 2mg (literature supported), 2) take sublingual drops (salivary gland absorption), 3) get im injections of methyl b12. ...Read more

Am 70yrs. I had bad depresion for 14 month, eat once daily and sleep 3 hrs. Does that cause macrocytic anemia. B12, folic ok. Can it be bad absorption?

Am 70yrs. I had bad depresion for 14 month, eat once daily and sleep 3 hrs. Does that cause macrocytic anemia. B12, folic ok. Can it be bad absorption?

Yes.: I may have answered this already. Depression can cause poor appetite and may cause malnutrition over a long period of time. However if your B12 and Folic Acid are normal, then I do not believe you have macrocytic anemia. The cause of macrocytic anemia is due to the absence of intrinsic factor in your stomach causing malabsorption of nutrients that can cause macrocytic anemia. ...Read more

Can hpylori bacteria cause macrocytic anemia for 70 yrs man. Had it from 2 yrs and treated. Folic, B12 ok. Can it be no absorption though normal vit.?

No: H. Pylori does not causes macrocytosis. If B12 is below 400, consider checking methylmalonic acid as it still could be B12 deficiency. In a 70 year old, maxrocytosis could be a sign of bone marrow disorder, called myelodyspalstic syndrome. Also, certain drugs can cause macrocytosis. ...Read more

Do I take vitamin b complex with magnesium or can I take vitamin B12? For better absorption of magnesium. Currently also take vit D3 thanks

Do I take vitamin b complex with magnesium or can I take vitamin B12? For better absorption of magnesium. Currently also take vit D3 thanks

OK but not 4 absorb.: It is perfectly fine to take b complex/b12 with magnesium but won't enhance absorption. Magnesium is best absorbed on an empty stomach ; b vits can cause stomach upset on empty stomach. B vits, esp. B6, often work in synergy with mag. The best-absorbed forms of mag. Are glycinate ; taurate; citrate is ok too. Epsom salt baths ; topical "magnesium oil" are also good ways to get magnesium into you. ...Read more

Serum b12> 1999 mma 0.4, homocysteine high 19. No folate (folic acid) or iron deficiency normocytic anemia not responding to procrit. Is this an absorption issue?

Anemia: Can be caused by blood loss or bone marrow suppression as well. More information is needed (how long have you had a normal iron, folate (folic acid) and b12 level. What is your reticulocyte count? (is your bone marrow producing new RBC's)? How low is your HCT and has it come up or gone down with B12. Is the RDW elevated (do you put out large and small RBC's at the same time? Any blood loss? ...Read more

Expert opinions? Which is better after colectomy: ileostomy or j-pouch?

J pouch usually requires a temporary ileostomy and thus an extra operation to close the temporary ileostomy.
