Two things I have learned post-sleeve (and these are important):
- The Vitamin B12 in a multi-vitamin PILL (or gummi) does NOT work in a sleeved stomach.
- A Vitamin B12 PILL (or gummi) will NOT work in a sleeved stomach.
The reasons are complex, you can look it up but basically the interaction between mouth saliva and stomach acid isn't sufficient to digest and absorb Vitamin B12 in your sleeved stomach.
So what can you do? You need 1000 mg of Vitamin B12 per month. Anything less and you WILL feel tired/lethargic all the time!
You basically have two options:
1. A 500ml injection of Methylcobalamin B12 in your butt twice a month. Do not use the far cheaper Cyanocobalamin injections, it doesn't work nearly as well....I found this out through experience!
2. A 1000mcg sublingual (under the tongue) B12 supplement. Again, look for the word "Methylcobalamin". This is for people who cannot stand needles. You CAN take two tablets if you still feel tired but about 50% of the population absorbs "too much" B12 at this level and it causes insomnia for them.
I just switched from Cyanocobalamin injections to Methylcobalamin injections 10 days ago and my energy level has increased tremendously! I couldn't figure out why so I went and did a little research.
