Choosing a quality multivitamin is easier with a few guidelines
Choosing a multivitamin-mineral supplement can be puzzling. Conflicting messages abound in the marketplace, especially on the Internet. And, as expected, the confusion is not helped by reports from the media that tend to overemphasize observational studies that confirm bias against supplementation. The reality is that the quality of multivitamin-mineral supplements ranges widely.
The highest quality dietary supplements are those designed according to current science and technologies—they use the most stable and efficacious forms of vitamins and minerals, have optimal solubility rates, are third-party tested for potency and shelf life, and provide optimal vitamin-and-mineral dosages that are divided over the course of the day for best absorption.
On the other end of the quality spectrum are the popular “one-a-day” supplements, which claim to provide all that the body needs in a single tablet; they may provide adequate amounts of many nutrients, but severely neglect others. Other supplements use synthetic vitamins when science demonstrates the body’s preference for the natural forms. Finally, some supplement companies claim higher absorption or bioavailability because their nutrients come directly from, or are paired with, “whole foods”; such claims are misleading because they are not presented with data. These vitamins do not actually come from whole foods, but are simply combined with botanicals that may even inhibit absorption.
Far be it for all marketers to paint a clear picture of the science, or for the media to do a little homework before lumping all dietary supplements in the same category of low quality and worthless. The fact is though, that there have been well-designed studies showing clear benefits from taking supplements in forms appropriate and in dosages that assist in meeting dietary recommendations for optimal health. If this weren’t true, or if multivitamins were somehow “dangerous”, then why do most medical doctors continue prescribing prenatal multivitamins to women who are expecting’
A proper review and critique of multivitamin-mineral supplements should be based on how well it reflects positions of scientific consensus on dosage, forms, and delivery. A few of the things to look for in a supplement are these:
Before ever venturing out to choose a multivitamin-mineral, each of the five points presented above should be considered by those looking to achieve the greatest value from their supplements. All things considered, my choice for a great vitamin is the Ageless Essentials Daily Pack, which comes in convenient A.M. and P.M. packets. Over the course of the day, the pack provides optimal dosages of essential vitamins and minerals such as vitamin D3 (2000 IU), calcium (800 mg for men, 900 mg for women), vitamin E as mixed tocopherols and d-alpha tocopheryl succinate (90 IU), and vitamin K2 (80 mcg).
The pack also includes a potent combination of bioactive compounds that support optimal health and longevity. These include patented, lipid-soluble CoQ10 (100 mg) backed by studies showing eight times greater bioavailability, maximum concentrations of ultra-purified DHAand EPA omega-3 fatty acids (600 mg EPA, 440 mg DHA), trans-resveratrol (250 mg), and more.
