Hello!
I know we should wait 4 months without any B12 supplements, injections, or fortified foods before testing B12 in the blood to get an accurate result.
What about the MMA test? Is the waiting period the same?
Thanks!
Hey!
I was worried about being one of the few people who are hyperresponsive to dietary cholesterol, so I followed an almost vegan diet along with low saturated fat intake.
My LDL dropped from 230 to 108 without any medication.
Around 1 month ago, I started eating fish again (100 g of sardines, mackerel or salmon) and 100g of turkey breast daily. Occasionally some eggs (but not many).
Now tested and my LDL didn’t increase, in fact, it went down from 115 to 108.
And eating fish did amazing for my triglycerides. It used to be around 100, now it is 54!
Does this mean I can eat more high-cholesterol foods without restrictions and not see my levels rise? I’d like to eat more eggs and chicken gizzards more often.
Thanks a lot!
In the B12 Wake Up group on Facebook, they say that when you have vitamin B12 malabsorption, the only treatment is injections and that supplements don’t work.
Even if the supplement increase the blood levels way above normal injections should be done. Is that true?
Hey guys can you looks at my iron history?
I was almost vegan for 2/3 years but I back eating 100g fish and 100g turkey breast daily (no other animal products) in the beggining of this year.
18/06/2025:
Ferritin: 159 ng/mL
Iron: 135 µg/dL
20/02/2026:
Ferritin: 83 ng/mL
Iron: 101 µg/dL
Start iron supplement: 20 mg, 3 times a week for 2 or 3 weeks
24/03/2026:
Ferritin: 160 µg/L
Iron: 81.5 µg/dL
Stopped supplement
30/04/2026:
Ferritin: 109 µg/L
Iron: 29 µg/dL
I don't have any new noticable symtom.
My blood panel is normal.
My b12 was low as well in the beggining of the year and I took supplement. 1000 mcg every other day for 10 weeks. I stop it 1 month ago.
What do you think about this? What is going on!?
Thanks!
Hey!
When you become B12 deficient due to a vegan diet, the enterohepatic recycling mechanism become permanently impaired.
Eating enough animal products no longer be enough, meaning you’d need artificial B12 for life?
And would that be pills or injections?
Thanks!
Hello!
I followed an almost vegan diet for a few years until last December, when my vitamin B12 dropped to 273 pg/mL.
At that time, my plan to maintain B12 levels was to eat fish 2 to 3 times per week, but I ended up eating only about one can of tuna per week on average, with no other animal products. I also wasn’t consuming any fortified foods.
After that result, I went back to eating animal products daily and started supplementing with hydroxy B12 (1000 mcg, 3 to 4 times per week) starting January 20th. Since then, my daily animal product intake has been about 90 g of fish (rotating sardines, mackerel, and salmon) and 100 g of turkey breast. That 's it.
My B12 history over the past few years:
09/05/2022: 364 pg/mL
08/01/2024: 524 pg/mL
18/06/2025: 461 pg/mL
(I think I went almost vegan in 2023)
24/12/2025: 273 pg/mL
(After this result, I changed my diet and started supplementation)
24/03/2026: 615 pg/mL
(After this result, I stopped supplementation on 03/04/2026 to try maintaining levels through diet alone)
30/04/2026: 401 pg/mL
(After just one month without supplementation, there was a significant drop)
Other relevant markers:
18/06/2025:
Ferritin: 159 ng/mL
Iron: 135 µg/dL
Folate: 13.19 ng/mL
20/02/2026:
Ferritin: 83 ng/mL
Iron: 101 µg/dL
Folate not tested
(I noticed a drop in iron levels and took supplements for 2 to 3 weeks: 20 mg, 3 to 4 times per week)
24/03/2026:
Ferritin: 160 µg/L
Iron: 81.5 µg/dL
Folate: 10.8 ng/mL
(After this result, I stopped iron supplementation)
30/04/2026:
Ferritin: 109 µg/L
Iron: 29 µg/dL
Folate not tested
(Iron is now below the limit, but ferritin is okay, so I’m confused...)
Can this first big drop be the result of ending the supplement and now don't drop much more?
And what the well is going on with my iron?
I have not had any new symptoms in recent years.
Thank you so much!
