I recommend New Zealand green-lipped mussels~

New Zealand green-lipped mussel 17,500 IU Vitamin D only needs to be taken once a day, one capsule. It contains 99.15% mussel extract, which is a shellfish. When eating, there is a slight smell of seaweed, but the fact that mussels are very good for joints is well known. It is also said to help reduce the risk of osteoporosis, so I have been diligently taking it for several years.
