NOW Ultra Omega 3-D
Brand: NOW · Form: SOFTGEL CAPSULE [E0161] On Market
Our assessment
Our assessment: The NOW Ultra Omega 3-D product is a combination supplement, and we must evaluate its calcium component specifically. The evidence shows that calcium is essential for bone health, but you need to be careful with dosing. The RDA for most adults is between 1,000 mg and 1,200 mg daily from all sources [NIH ODS].
How it works
Think of calcium as a building block for your skeleton. It supports bone mineralization and density, and it is also critical for neuromuscular relaxation and nerve signaling [NIH ODS]. Without enough calcium, your body will leach it from your bones, weakening them over time.
Safety profile
Data not available for this specific product. However, FDA has received a total of 592,059 adverse event reports across all dietary supplements [FDA data]. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Very high levels in the blood can cause constipation, nausea, weight loss, extreme tiredness, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Calcium can also reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, and levothyroxine [NIH ODS].
Our recommendation
Our recommendation: Check the label for the exact calcium dose in this product, then add up your total daily intake from food and other supplements. Do not exceed 2,000 mg total per day from all sources unless directed by your doctor [NIH ODS]. If you take any prescription medications, take calcium supplements at least two hours apart from those drugs [NIH ODS].
