One of the biggest mistakes people make is taking inexpensive vitamins or buying them based on "deals". Cut-rate products often contain additives, food allergens, sugar, artificial food coloring and flavoring. Many are coated with shellac, or contain potentially hazardous chemicals like chlorine. We know from various studies that potency and purity can vary widely from pill to pill and bottle to bottle. Another problem is freshness.
Most supplement companies would worry about a visit from the FDA, but Shaklee scientists invited FDA representatives to the Norman, Oklahoma manufacturing plant to discuss quality control standards for the industry. The FDA came away impressed by the rigorous quality control measures at Shaklee that far exceed those typically found in the dietary supplement industry.There will always be bogus ingredients in the marketplace.
