Although less than two dozen cats were actually reported as being afflicted with a B1 deficiency, it is impossible to tell how many felines were displaying latent symptoms of the condition, symptoms that went unnoticed by their owners.
These include, vitamin B1 (thiamine), vitamin B2 (riboflavin), vitamin B3 (Niacin), vitamin B5 (pantothenic acid), vitamin B6 (pyridoxine), vitamin B7 (biotin), vitamin B12 (cobalamin), and choline (the unofficial B vitamin).
Since the average household cat has no access to other viable sources of B1, repeated intake of a deficient food product will lead to an incidentally irreversible thiamine deficiency.
Vitamins can help increase hair growth, so taking a multivitamin rich in B vitamins or vitamins B12, B6 and B1 supplements, can provide your hair with the nutrients it needs.
This supplement contains vitamins C, D2, E, B1, B2, B3, B6, B12, folic acid, iodine, zinc, copper and magnesium, along with PABA, Fenugreek, Aloe Vera and silica.
