It’s possible to find high-quality vitamin/mineral supplements at the health food store that use only co-natural vitamins and no synthetics. The problem with supplements based on co-naturals is that they can never be complete.
The will never contain the unknown factors such as vitamin
B29, which will not be identified for another hundred years. What
co-naturals are useful for is “spiking up” a supplement based on one of
the optimum options above. An example would be a “food-based” supplement
augmented with co-natural vitamins E and C.
Avoid At All Costs:
Supplements made in whole, or part, from synthetics or elemental
nutrients are not an option. At their best, they are only 50 percent as
effective as a natural vitamin. At their worst, they actually may carry
harmful side effects. Key red flags to look for in ingredient lists are
dl-alpha-tocopherol, ascorbic acid, and oyster shell calcium
