It’s pretty hard to find an accurate answer on how much vitamin D your body needs. Strong and healthy bones are not easy goals to measure, and therefore also difficult to improve. Doctors generally determine that you can measure an individual’s Vitamin D level by checking the serum 25-hydroxyVitamin D in their blood. However, this measurement has some problems historically, making it difficult to standardize. Even taking Vitamin D supplements has its own course of action. It depends on how well your body can absorb its benefits. If your body fails to absorb Vitamin D properly, you will need a higher dose of supplements.
But, Vitamin D is indeed essential for calcium absorption, which results in bone strength. It helps with optimal skeletal muscle functionality as well. Furthermore, this vitamin is necessary at every age. You can achieve bone strength at its peak level while reaching 20 to 25 years of age. Deficiency of Vitamin D and calcium will come back hard on you during old age, more likely from 50 to 90 years of age. However, if you ever get the chance to maximize bone strength, you should go for it. Vitamin D is excellent for that and many other things.
