FAT VS. WATER-SOLUBLE VITAMINS

Ricky Rubin

Thiamine or thiamin or vitamin B1 is a water-soluble vitamin of the B complex.

WATER-SOLUBLE VITAMINS: (all vitamins B-complex and C). Dissolve in water, are NOT STORED BY THE BODY (low toxicity risk), and are easily absorbed then excreted by the kidneys. OBTAINED FROM DIET. Function to release energy (ATP) from consumed foods through the metabolism of fats, proteins, and carbohydrates. Involved in HEMOPOIESIS (RBC and platelet production in bone marrow). Water-soluble vitamin deficiencies often cause oral pathology (ex: petechaie, angular cheilitis, and glossitis). 

FAT-SOLUBLE VITAMINS (A, D, E, K): absorbed through the intestinal tract and stored in the LIVER and adipose tissues for long periods, thus pose a greater toxicity risk due to accumulation (not readily excreted by the kidneys). Exccessive accumulation can lead to HYPERVITAMINOSIS.
