multivitamin absorption
A little over a year ago I was diagnosed with Celiac disease and so I have some nutritional deficiencies. So I have looked into several multivitamins and have learned what favorable forms of nutrients to look for in a multivitamin. As mentioned in other reviews this vitamin has the desirable, natural forms of vitamins and nutrients. I have had a lot of energy during the day since I started taking it over a month ago. It compares favorably with other more expensive vitamins. But I was concerned about the vitamin being in tablet form rather than capsule, thinking it may not dissolve well. Being an Organic Chemistry professor, I have access to a variety of individuals with other science based backgrounds. In our Microbiology department, they have an instrument called a stomacher, which mimics the activity of a human stomach. I placed two of the Rainbow light multivitamins, along with a couple other supplements in a bag containing plain distilled water and a little enzyme (overall pH approximately 6). This bag was placed in the stomacher for about 5 minutes. When it came out the solution was pretty much homogeneous (uniform solution) throughout and a yellow / green color. I think other reviewers only considered the pH of the stomach (as I originally thought), but there is a lot of agitation that occurs within to break up food and whatever else is swallowed. So the take home story is it looks like I can stop chewing it up before swallowing it. It is convenient to take one tablet a day but not optimal. Any vitamin has half lifes where the effectiveness diminishes throughout the day. It would be better to take a series of vitamins and minerals throughout the day.
