Emergen-C Vitamin D & Calcium Mixed Berry
Brand: Emergen-C · Form: POWDER [E0162] On Market
Our assessment
The evidence shows that this product provides a combination of calcium and vitamin D, nutrients that work together for bone health. For most adults, the RDA for calcium is 1,000 mg daily, and for vitamin D it is 600 IU daily [NIH ODS]. This supplement can help you meet those targets, but it is important to consider your total intake from food and other supplements to avoid exceeding safe limits.
How it works
Think of calcium and vitamin D as a team for your bones. Calcium supports bone mineralization and density, while also playing a role in muscle relaxation and nerve signaling [NIH ODS]. Vitamin D helps your body absorb that calcium effectively. Without enough vitamin D, your body cannot use the calcium you consume, making this combination particularly effective for skeletal health [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports for this product. Regarding calcium specifically, very high intakes can cause constipation, nausea, and abnormal heart rhythms [FDA data] [NIH ODS]. High calcium levels in the blood may also lead to poor kidney function and extreme tiredness [NIH ODS]. Some research suggests that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. You should also be aware that calcium can reduce the absorption of certain medications, including bisphosphonates, tetracycline antibiotics, and levothyroxine [NIH ODS].
Our recommendation
Start by assessing your total daily calcium intake from food and other supplements. If you are already getting 800-1,000 mg from your diet, you may not need this supplement. If you do use it, take it with food and separate it from any thyroid or antibiotic medications by at least two hours [NIH ODS]. Data not available for the specific vitamin D dosage in this product, so check the label carefully to ensure you are not exceeding 4,000 IU per day from all sources [NIH ODS].
