Absent any impaired absorption, age-related or otherwise, with a high dose oral B12 supplement one would in general expect to absorb (up to) 1-2 micrograms via intrinsic factor plus about 1% via passive diffusion. Do you have any data one how much B12 is absorbed (per tablet) with your specific, time release formulation? Thank you.
P.S.: For sustainability reasons, a greater than 60 tablets package size would be much appreciated- maybe also forgoing the plastic bottle completely.
Hi, it is difficult to give absolute figures as there are so many factors involved, however we do know the sustained release tablet format makes the B12 available for absorption over a 4-8 period, which gives the body a very good chance to absorb the vast majority of it. B12 is highly water-soluble and so the body takes what it requires with the rest safety excreted. Our current bottles are a sugar cane compound that is 100% biodegradable within 10 years.
