Thiamine (Vitamin B1) is essential for converting carbohydrates into usable energy and maintaining healthy nerve function in your hamster. The nervous system is particularly sensitive to thiamine levels, and since hamsters have a high metabolic rate relative to their size, they burn through B vitamins quickly. Whole grains, seeds, and legumes are good natural sources. Thiamine is water-soluble and not stored in the body, so a consistent daily supply from the diet is important.
A teaspoon of whole oats provides roughly 0.05mg of thiamine — your hamster needs approximately 4-8mg of thiamine per kilogram of feed, translating to about 0.05-0.1mg per day. Whole grains, fortified pellets, and seeds provide adequate thiamine in a balanced diet.
0.0% of daily nutrient intake
Vitamin B1 (Thiamine) makes up 0.0% of your hamster's total daily nutritional requirements by weight. That's a tiny amount — but it matters.
Neurological symptoms including uncoordinated movement, head tilting, circling, muscle weakness, loss of appetite, weight loss, and in severe cases seizures or paralysis. Thiamine deficiency can develop within weeks on an inadequate diet because body stores are minimal.
Thiamine excess is not a practical concern. As a water-soluble vitamin, any excess is excreted in the urine. Toxicity from dietary sources does not occur.
