Nutrition Now Calcium + D3 500 mg/1000 IU
Brand: Nutrition Now · Form: GUMMY [E0176]
Our assessment
The evidence shows that this combination supplement is a straightforward way to meet your daily needs for two essential nutrients. Our assessment is that for most adults, this product offers a standard dose of 500 mg of calcium and 1000 IU of vitamin D3, which aligns with general bone health recommendations [NIH ODS]. However, you should be aware that the data on calcium supplementation has important safety considerations that we will cover below.
How it works
Think of calcium and vitamin D as a team. Calcium is a mineral that supports bone mineralization, muscle relaxation, and nerve signaling [NIH ODS]. Vitamin D3 helps your body absorb that calcium effectively. Without enough vitamin D, your body cannot properly use the calcium you take in, which is why they are so often paired together in a single supplement [NIH ODS].
Safety profile
FDA has received a total of 592,059 adverse event reports for products in this category [FDA data]. Regarding calcium specifically, some research suggests that high intakes might increase the risk of heart disease and prostate cancer. High levels of calcium in the 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
We recommend you use this supplement only if your diet is low in calcium and you have confirmed low vitamin D levels. The 500 mg of calcium is a moderate dose, so you should calculate your total daily intake from food and other supplements to avoid exceeding recommended limits. Be sure to take this supplement at a different time than any medications listed above to avoid absorption issues [NIH ODS].
