Q: my b12 level was <109 pmol/l. i took half of the vitamin course, 500 mg daily for about a month, then stopped and tested two months later and the result is 133. is this normal absorption given finishing half of the course? if not, what's the cause?

Malabsorption: Your stomach and intestine may not be absorbing B12 normally. You may need to get injection of vitamin B12. You may try taking sub-lingual form of B12 for three months and repeat the test to see if you may be able to avoid getting injections.

Q: 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.

Q: effect of acid secretion on absorption of iron and vitamin b12?

Acid has a profound: Effect on iron. Acid is better. Not an issue with b12, as the issue is intrinsic factor from the stomach which is a cofactor in B12 absorption.

Q: 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.

Q: is it better to swallow or chew vitamin b12 tablets to maximize absorption?

Chew: Chewing it might expose more surface area of the B12 vitamin to the intrinsic factor in the stomach that carries the vitamin to the terminal ileum where it gets absorbed.

Question 1

how can i keep my energy levels since i had a total colectomy with j pouch? not anemic, b12 and thyroid are find.

Accepted Answer

Sometimes: A lack of energy in someone with your surgery is due to dehydration. Try drinking 80-100 ounces of gatorade type fluids daily. See your surgeon to discuss other potential deficiencies that might explain you lack of energy.

Question 2

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?

Accepted Answer

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.

Question 3

does sublingual b12 absorption work?

Accepted Answer

B12 deficiency: Intranasal, sublingual, oral, and intramuscular are all effective means of increasing vitamin B12 levels.

Question 4

took omerprazole on and off for a few years. b12 low. will b12 absorption return to normal now i know longer take omerprazole? or absorption will always be hindered from historic omerprazole use? thank you?

Accepted Answer

: You may take sub-lingual form of vitamin B12 to partially circumvent the intestinal absorption issue.
For healthy diet: http://www.choosemyplate.gov/., exercise 30 minutes/day, drink enough water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs. 
Get HPV and Covid vaccines. Wish you good health!

Accepted Answer

NO: by the time it dissolves under your tongue- it should be absorbed and not affected by coffee.

Question 6
