Guest guest Posted March 25, 2009 Report Share Posted March 25, 2009 Are there any reliable methods for testing nutrient deficiency? Hair analysis is at best very controversial. If there were a very reliable test of nutrient deficiency then there would be much less controversy over supplementation. If a test could determine accurately which nutrients a body needed then it would only be necessary to take supplements meeting the tested nutrient deficiencies not the endless array of supplements recommended by some and tons of trial and error with supplements to meet the deficiency. Thanks for any replies. Quote Link to comment Share on other sites More sharing options...
