Riboflavin (Vitamin B2) helps your hamster convert food into usable energy and supports healthy skin, eyes, and red blood cell production. It works as a coenzyme in numerous metabolic reactions, particularly those involving fat and protein metabolism. Like other B vitamins, riboflavin is water-soluble and needs regular replenishment from the diet. Seeds, grains, eggs, and dark leafy greens all contribute to riboflavin intake.
A small piece of cooked egg (about 2g) provides roughly 0.01mg of riboflavin — your hamster needs approximately 4-8mg of riboflavin per kilogram of feed, about 0.05-0.1mg per day. Fortified pellets, whole grains, and occasional egg provide adequate supply.
0.0% of daily nutrient intake
Vitamin B2 (Riboflavin) makes up 0.0% of your hamster's total daily nutritional requirements by weight. That's a tiny amount — but it matters.
Rough, scaly skin, hair loss, eye problems (cloudy or inflamed eyes), poor growth in young hamsters, reduced energy, and anemia. Severe deficiency can cause neurological symptoms.
Riboflavin excess from dietary sources is not a concern. Any surplus is excreted in the urine, which may appear bright yellow — this is harmless.
