Overview
Bronson's B12 tablet delivers 1000 mcg of vitamin B12 in a sustained release tablet, formulated non-GMO, in a 100 count bottle aimed at nervous system and energy support.
Sustained release means the tablet is built to release its B12 gradually rather than all at once, which is the main thing separating it from a standard immediate release B12 tablet at the same dose. As a water soluble vitamin, B12 the body does not use gets excreted rather than stored, which is the usual reasoning behind a sustained release format.
- 1000 mcg vitamin B12 per tablet
- Sustained release delivery
- 100 tablets per bottle
- Non-GMO formulation
Who it's for
Aimed at people supplementing B12 for energy or nervous system support, particularly anyone on a diet that limits B12 rich animal foods. Not a substitute for treating a lab-confirmed B12 deficiency, which typically needs a doctor's guidance on dose and form.
Pros and cons
- 1000 mcg dose per tablet, a common B12 supplementation level
- Sustained release format
- 100 count bottle, over three months at one tablet daily
- Tablet form may absorb less reliably than sublingual or liquid B12 for some people
- Unflavored, plain tablet
Performance notes
The sustained release tablet is built to extend how long the B12 stays available for absorption, compared with a tablet that dissolves and releases its full dose right away.
