The missing numbered B vitamins were reclassified or determined not to be vitamins. For example, B<sub>9</sub> is [[folic acid]] and five of the folates are in the range B<sub>11</sub> through B<sub>16</sub>. Others, such as [[4-Aminobenzoic acid|PABA]] (formerly B<sub>10</sub>), are biologically inactive, toxic, or with unclassifiable effects in humans, or not generally recognised as vitamins by science, such as the highest-numbered, which some [[naturopath]] practitioners call B<sub>21</sub> and B<sub>22</sub>. There are also lettered B substances (e.g., B<sub>m</sub>) listed at [[B vitamins]] that are not recognized as vitamins. There are other "D vitamins" now recognised as other substances, which some sources of the same type number up to D<sub>7</sub>. The controversial cancer treatment [[laetrile]] was at one point lettered as vitamin B<sub>17</sub>. There appears to be no consensus on the existence of substances that may have at one time been named as vitamins Q, R, T, V, W, X, Y or Z. | The missing numbered B vitamins were reclassified or determined not to be vitamins.
