Therefore, the benefits of fermented cod liver oil supersede the benefits of standard cod liver oil.
Some of the frequently asked questions about cod liver oil:
1. Should pregnant or breastfeeding women avoid it?
Definitely, a breastfeeding woman needs the recommended daily intake of vitamins to bring up a healthy child.
However, our daily required vitamin A is fulfilled by a variety of foods and vegetables we eat every day, and vitamin A deficiency is rare in the United States and other developed nations.
But, it is common in third world countries (developing countries) where many people don't have enough eatables to get their daily required vitamins especially breastfeeding and pregnant women.
However, increased numbers of minerals and vitamins are required for a breastfeeding woman to provide proper milk supply to the infant.
Therefore, a breastfeeding woman needs multivitamin supplements along with fruits and vegetables to cope with the increased demand of nutrients.
Also omega-3s (DHA&EPA or referred as marine omega-3s or n-3 fat) which are found in cod liver oil are good for fetal neurodevelopment and timing of
Therefore, if you are not getting enough omega-3s from your diet, taking them as supplements is a good idea.
Cod liver oil also provides enough vitamin D, and can fulfil the deficiency of it in breastfeeding and pregnant women.
2. Is it effective to treat osteoporosis?
In Osteoporosis, the bones become porous and fragile that results to loss of bone strength.
However, there is a widespread misconception that calcium and vitamin D deficiency is the main cause of weak bones, but it is not true, a healthy diet which is rich in all types of minerals and vitamins keeps the bones rigid and provide them
Also, exposure to sunlight provides us approx. 90% of our required vitamin D and rest of the amount can be absorbed by our daily diet.
Therefore, if we say that cod liver oil alone helps in relieving from osteoporosis it is not correct, however, it is a good source and can provide you enough vitamin D if you are a vitamin D deficient (a 100 gram serving of CLO provides you 210 mcg of vitamin D).
Really Cod liver oil is a good source of omega-3s, vitamin D, and vitamin A and helps to fight with many severe medical conditions.
However, it is necessary to see the labels on supplements before using and consult your doctor before taking any supplement.
