The parts about CODEX ALIMENTARIUS, WHO and WTO do not seem to be false alarms, as best as I can tell. See my several posts above.
And you got the wrong year in your research. These House and Senate bills, for the 108th Congress, were on the topic at hand:
Dietary Supplement Safety Act of 2003 (Introduced in Senate)
S 722 IS
108th CONGRESS
1st Session S. 722 To amend the Federal Food, Drug, and Cosmetic Act to require that manufacturers of dietary supplements submit to the Food and Drug Administration reports on adverse experiences with dietary supplements, and for other purposes.
IN THE SENATE OF THE UNITED STATES
March 26, 2003 Mr. DURBIN introduced the following bill; which was read twice and referred to the Committee on Health, Education, Labor, and Pensions
Dietary Supplement Access and Awareness Act (Introduced in House)
HR 3377 IH
108th CONGRESS
1st Session H. R. 3377 To amend the Federal Food, Drug, and Cosmetic Act with respect to dietary supplements.
IN THE HOUSE OF REPRESENTATIVES
October 28, 2003 Mrs. DAVIS of California (for herself, Mr. WAXMAN, and Mr. DINGELL) introduced the following bill; which was referred to the Committee on Energy and Commerce
And so I suspect the article you initially posted is a bit confused, mixing news of early 2005 (about WHO, CODEX and WTO) with old warnings of last sessions bills.
