In addition to its bone health benefits, there’s growing evidence that getting extra vitamin D can help other areas of the body. In order to help eliminate these risks, some health authorities recommend that adults should aim to get at least 1,000 to 2,000 IU of vitamin D per day. These amounts will likely require an extra vitamin D supplement, in addition to your daily multivitamin.[1]

The Harvard School of Public Health suggests a once daily multivitamin with extra vitamin D for most people as a nutritional back-up.[2] Because most multivitamins don’t include enough vitamin D or calcium, it is suggested to take these nutrients as additional supplements.

In North America, diets that are rich in fortified milk, fish, and/or other calcium-fortified foods and beverages can help towards optimizing your vitamin D levels however these foods contain only a very small amount of vitamin D. In the UK, cows’ milk is generally not a good source of vitamin D because it isn’t fortified at all like it is in many other countries.[3]

Vitamin D has several functions and is very important, especially during periods of rapid growth such as early infancy. For example, it helps to regulate the amount of calcium and phosphate throughout the entire body. These nutrients are needed to help keep bones and teeth strong and healthy for everyone at any age. A lack of vitamin D can lead to bone deformities such as rickets in children, and bone pain and tenderness as a result of a condition called osteomalacia in adults. Osteomalacia is softening of the bones and it occurs because of a lack of vitamin D or a problem with the body’s ability to break down and use this vitamin properly. Your body needs calcium to maintain the strength and hardness of your bones.[4]

Vitamin D is naturally made by our body under the skin, in reaction to summer sunlight. The amount of vitamin D you get from exposing your bare skin to the sun depends on quite a few factors like; the time of day, where you live and the easier it is for your body to produce vitamin D from sunlight. A good trick is if your shadow is longer than you are tall, your body is not making very much vitamin D. Your body doesn’t make too much vitamin D from sun exposure, but always remember to cover up or protect your skin if you are out in the sun for long periods.

It is always good to consider what other supplements you are already taking before adding additional supplements. Ddrops® products are uniquely suited to support daily vitamin D requirements only. Many multivitamins already contain vitamin D, but the dosages vary and labels should be looked at carefully. It is always best to talk to your healthcare provider as they would be most familiar with what’s best for you and your family.
