Nordic Naturals Ultimate Omega-D3 Lemon
Brand: Nordic Naturals · Form: SOFTGEL CAPSULE [E0161]
Our assessment
The evidence shows that the key active ingredient in Nordic Naturals Ultimate Omega-D3 Lemon is not vitamin D, but calcium. Our assessment: calcium is a critical mineral for bone health and nerve function, but it carries significant risks that you need to understand before taking any supplement containing it [NIH ODS].
How it works
Think of calcium as a structural builder for your skeleton. It supports bone mineralization and density, and it also plays a role in neuromuscular relaxation and nerve signaling [NIH ODS]. However, you should be aware that this product's label lists calcium, not vitamin D, as the active ingredient. For vitamin D content specifically, the data is not available.
Safety profile
FDA received 592,059 adverse event reports related to this ingredient category. The specific risks for calcium are serious: high intakes might increase the risk of heart disease and prostate cancer. Symptoms of excessive calcium in the blood and urine include 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
Because data on this product's vitamin D content is not available, and because calcium carries significant cardiovascular and kidney risks, do not take this supplement without first consulting your doctor. If you need calcium, get it from food sources first. If you take calcium supplements, never exceed the recommended dose and monitor for symptoms of toxicity [NIH ODS].
