A balanced diet is no longer enough – supplements needed - VitaminDWiki Oct 2012

The amount of Vitamin D, Magnesium, etc. no longer even gets to the level of the RDA

And, the RDA is somewhat similar to the minimum wage, not enough to live on

And there is a huge interaction between Vitamin D, Magnesium and Vitamin K2

There has been at least a 2X reduction in the amount of

• Vitamin D 33 reasons, which include:
  People are indoors more, pigs are indoors, chickens are indoors, fish are farmed (4X less vitamin D),
  People consume less cholesterol, polyunsaturated foods,
  More people are lactose intolerant and do not get vitamin D from milk
• Magnesium for reasons such as
  Chemical fertilizers have far less Magnesium
  Far less Magnesium in bottled or softened waters
  80% less Magnesium in refined wheat
  Magnesium blocked by increased use of Calcium supplements and Fluoride
  Little Magnesium remains after sugar is refined
  80% less Magnesium in white vs brown rice
• Vitamin K2
  Cattle often now eat corn instead of grass
  Farmed fish have much less Vitamin K2 (Fish on farms typically are fed grain, not krill)
     Farmed salmon have 4X less vitamin D. Wonder about Magnesium.
• Omega-3 Fatty Acids
  Far less Omega-3 fatty acids from cows fed on grains than on grass
  Far more (bad) Omega-6 fatty acids from Corn, soy products
  Eat less fish, and farmed fish have far less Omega-3
    Omega-6 fatty acids trippled from 7 grams in 1909 to 25 grams in 1985

  Centrum Silver ingredients
      had been only 400 IU of Vitamin D, 100 mg of Magnesium, and 10 mcg of vitamin K
      Centrum in 2012 has increased Vitamin D and tripled Vitamin K (probably not K2) to 30 mcg, but halved Magnesium to 50 mg
     VitaminDWiki expects that results would have been far better if Centrum Silver had 2000 IU of vitamin D, 100 mcg of Vitamin K2, and 300 mg of Magnesium
