accumulation of uric acid crystals in and around joints).

Interactions with Dietary Supplements
Vitamin
B12
Colchicine may interfere with vitamin B12 in the body. Research is inconsistent. Both
colchicine and vitamin B12 deficiency are reported to cause neuropathies (disorders of the
nervous system), but it remains unclear whether neuropathies caused by colchicine could be due
to vitamin B12 depletion.1 2
Nutrient malabsorption
Colchicine has been associated with impaired absorption of beta-carotene, fat, lactose (milk sugar), potassium, and sodium.3
