Atlantic Naturals Immune Complex Elderberry

Our assessment

The evidence shows that Atlantic Naturals Immune Complex Elderberry contains calcium as an ingredient. Based on the data provided, we cannot assess the specific benefits of the elderberry component, as no data on elderberry was supplied. For the calcium content, our assessment is that it supports bone density and muscle relaxation, but you need to be aware of important safety considerations [NIH ODS].

How it works

Think of calcium as a structural builder and a nerve signaler. It works by supporting bone mineralization and mineral deposition, which helps keep your skeleton strong. It also plays a role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly [NIH ODS].

Safety profile

Data not available for this specific product. However, for the calcium ingredient, FDA has received a total of 592,059 adverse event reports across all supplements. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. High levels 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] [FDA data].

Our recommendation

Our recommendation is to be cautious. Calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. You should take this product at least two hours apart from those medications. Because the data on the elderberry component is not available, we cannot fully assess this product's safety and efficacy. Consult your healthcare provider before starting, especially if you have kidney issues or take prescription medications.
