It also supports bone health by aiding calcium absorption, which is attributed to vitamin D. Additionally, the omega-3 fatty acids may help in reducing inflammation and supporting cardiovascular health by promoting healthy cholesterol levels.
Cod liver oil is commonly available in liquid form or as soft gel capsules. It can be taken daily as a supplement to help meet nutritional needs that might not be fully covered by diet alone, such as during periods of increased nutritional demand.
While cod liver oil offers several health advantages, excessive intake of vitamin A can be harmful. Therefore, it is important to follow recommended dosage guidelines to avoid potential adverse effects, such as those related to vitamin A toxicity.
