No: The average 500 mg capsule of cod liver oil contains approximately 1000 IU of Vitamin A and 225 IU of Vitamin D. The acute toxic dose of Vitamin A for an average adult is >660,000 units of Vitamin A, which would be 600 capsules of cod liver oil. Acute toxicity of Vitamin D in adults is generally a non-issue as it would take a massive overdose to cause acute symptoms.
