ProCaps Laboratories Vitamin D3-1000
Brand: ProCaps Laboratories · Form: CAPSULE [E0159] On Market
Our assessment
The evidence shows that this supplement provides 1,000 IU of vitamin D3 per serving, which is above the standard 600 IU RDA for most adults [NIH ODS]. Our assessment: this is a reasonable dose for many people, particularly if you have limited sun exposure or are over age 70, but you should not take additional vitamin D supplements without checking your blood levels first [NIH ODS].
How it works
Vitamin D acts as a master regulator in your body. It is essential for calcium absorption and bone mineralization, helping to maintain strong bones and support muscle relaxation and nerve signaling [NIH ODS]. Think of it as a key that unlocks your body's ability to use calcium effectively — without enough vitamin D, your bones can become thin and brittle [NIH ODS].
Safety profile
The FDA has received a total of 592,059 adverse event reports across all dietary supplements. Data not available for specific side effect counts for this exact product. High levels of vitamin D can lead to elevated calcium in the blood, which may cause poor muscle tone, poor kidney function, constipation, nausea, weight loss, extreme tiredness, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Be aware that calcium supplements may reduce the absorption of medications such as bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Start with 1,000 IU of vitamin D3 daily. For best results, take it with a meal that contains fat to improve absorption. Have your blood levels checked after three months to ensure you are in a healthy range. Do not combine this with other vitamin D supplements without medical supervision [NIH ODS].
