Overview: Conventional wisdom previously dictated that a person who eats a varied diet does not need dietary supplements Cordyceps private label. Concern about wasting valuable resources on unneeded supplements and possible toxic reactions led many health care professionals to advise against anything more than a basic vitamin and mineral supplement that contained only the basic RDA recommendations.
Recent data about the role of vitamins and minerals, not just to prevent classic deficiency states, but to alter the course of chronic diseases, prevent cancer and heart disease, and/or to optimize the functioning of a healthy individual, have continued to raise the question of whether a higher dose supplement might not be beneficial.
This is a hotly debated area of medicine today. Practicing physicians must make decisions about what to recommend everyday based on incomplete research information. Each clinician must make their own choice based on their evaluation of the literature. Thus, whether we are only trying to answer our patients’ questions, or trying to formally recommend appropriate supplements to our patients, we must not only answer the question, “What is the level of intake…judged to be adequate to meet the known nutrient need of practically all healthy persons,” the question answered by the National Research Council in determining the RDA’s, but we must delve further into determining the level of intake judged to be optimal to meet the nutrient needs of those for whom we care.
To answer this question in future posts, we will address four issues for each vitamin and mineral reviewed: 1. What are the known sources and biochemical function(s) in the human body of each vitamin or mineral? 2. What are the possible safety concerns and the safety ranges for the vitamin or mineral? 3. What are the current recommended daily allowances? and 4. What is the published medical literature tell us about each vitamin and mineral? At the conclusion of the review recommendations will be made for an “evidence-based supplement” for our readers.
Who Should Take a Supplement? The decision whether to recommend a supplement and at what dose is more complex than it may initially appear. Several variables must be considered in order to make an educated guess at what will best benefit an individual. These include the average dietary intake of the individual with regard to vitamins and minerals, their age and gender, any metabolic or endocrine function that increases their needs, any medical illnesses they have that may impact their ability to absorb, utilize, or increase their daily needs, and the effect of medications the individual may be taking on vitamin and mineral metabolism in the body.
