20 key bone building nutrients — an overview

By 4 years ago

Depending on how we count them, there are at least 20 bone building nutrients which are essential for optimal bone health — “essential” in that our bodies cannot manufacture them, so we must get them from our food and drink. Let’s take a quick look at them, one by one, so you can get a better idea of their roles in bone health and how much of each you should be getting.

Remember, none of these nutrients does its work in isolation — you need some of each and every one, so they can all work together to keep your bones standing strong all your life long. Taking a top-grade multivitamin–mineral complex and essential fatty acids will ensure that your cells have adequate levels of these nutrients ready at hand from minute to minute, day after day, to prevent bone loss leading to osteoporosis, other degenerative diseases, and accelerated aging.

About… Dietary Reference Intakes (DRI),
Adolescent Recommended Dietary Allowances (RDA),
Adult Recommended Dietary Allowances (RDA),
Adequate Intakes (AI), and
Estimated Average Requirements (EAR)

    • The Dietary Reference Intake (DRI) is a system of nutritional guidelines developed by the Institute of Medicine (IoM) of the US National Academy of Sciences. It was first introduced in 1997 to broaden the set of existing Recommended Daily Allowance (RDA), which is the system currently still in use in food nutrition labeling. The DRI includes two sets of values that serve as goals for nutrient intake (from the National Academy of Sciences). These are the RDA andAdequate Intake (AI).
    • Table of RDAs for Adolescents and Teenagers.

    • Recommended Dietary Allowances (RDA) represents the daily dietary intake of a nutrient regarded to be sufficient for meeting the requirements of nearly all (97–98%) healthy individuals in each age and gender group. The RDA reflects the average daily amount of a nutrient considered adequate to meet the needs of most healthy people. If there is insufficient evidence to determine an RDA, an AI is set.Adult RDA figures come from: National Academy of Sciences, Institute of Medicine, and the Food and Nutrition Board, through the United States Department of Agriculture Food and Nutrition Information Center website.

    • Adequate Intake (AI) values are more tentative than RDA, but both may be used as goals for nutrient intake.

  • In addition to the values that serve as goals for nutrient intakes, the DRI includes a set of values called Tolerable Upper Intake Levels (UL). The UL represent the maximum amount of a nutrient that appears safe for most healthy people to consume on a regular basis.
  • The Estimated Average Requirement (ERA) calculations are the average daily nutrient intake level estimated to meet the requirement of half of the healthy individuals in a particular life stage and gender group. They are established by the Institute of Medicine (IoM).

Keep in mind that these are values that are meant to cover adequacy for most folks, not for optimizing health! The common therapeutic dose for bone health may be significantly higher in “special need” cases.
