Sundown Naturals Liquid-Filled Calcium Plus Vitamin D3
Brand: Sundown Naturals · Form: SOFTGEL CAPSULE [E0161] On Market
Our assessment
The evidence shows that Sundown Naturals Liquid-Filled Calcium Plus Vitamin D3 can be an effective way to support bone health, but you need to be aware of specific dosage and safety considerations. The key ingredient, calcium, plays a critical role in bone mineralization and density [NIH ODS].
How it works
Think of calcium as the building block for your skeleton. It supports bone mineralization and density, and also helps with neuromuscular relaxation and nerve signaling [NIH ODS]. This combination with vitamin D3 helps your body absorb the calcium you take in.
Safety profile
FDA received a total of 592,059 adverse event reports across all supplement categories. For calcium specifically, some research suggests that high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. High levels of calcium in your blood and urine can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Start by reviewing the label for exact dosage information. Because calcium can interact with common medications, you should take this supplement at least two hours apart from any prescription drugs you use. If you have a history of kidney stones, heart disease, or prostate cancer, consult your doctor before starting this supplement. Data not available on specific report counts for this product alone.
