Difference Between Prescription Vitamin D And Over The Counter
Vitamin D is essential for the proper functioning of our body. It helps the body absorb calcium, which is necessary for strong bones and teeth. It is also important for the functioning of our immune system and maintaining a healthy heart. Our body produces vitamin D when we are exposed to sunlight. However, due to various reasons, many people may not get enough vitamin D from sunlight alone. In such cases, vitamin D supplements may be required.
Prescription Vitamin D
Prescription vitamin D is a type of vitamin D supplement that can only be obtained with a prescription from a healthcare provider. It is usually prescribed for people with a vitamin D deficiency or those who have conditions that make it difficult for their bodies to absorb vitamin D. Prescription vitamin D is available in different forms such as capsules, tablets, and injections. The dosage and duration of the prescription are determined by the healthcare provider based on the individual's needs.
Over The Counter Vitamin D
Over the counter (OTC) vitamin D supplements are vitamin D supplements that can be purchased without a prescription. They are available in various forms such as tablets, capsules, drops, and gummies. OTC vitamin D supplements are usually recommended for people who do not have a vitamin D deficiency but need additional vitamin D for maintaining their overall health. The dosage and duration of the supplement are usually mentioned on the label, and it is recommended to follow the instructions carefully.
