Our assessment
The evidence shows that this product contains calcium, but for St. John’s Wort, Ginseng, and Ginkgo, data is not available from the provided sources. For the calcium component, our assessment is that it supports bone health, but the risks and interactions require careful attention. You should not take this supplement without consulting your healthcare provider, especially if you are on any medications [NIH ODS].
How it works
Calcium is a master regulator for your body. It supports bone mineralization and density, and it is critical for neuromuscular relaxation and nerve signaling [NIH ODS]. For the other ingredients in this product—St. John’s Wort, Ginseng, and Ginkgo—specific mechanisms of action are not available from the provided data.
Safety profile
The FDA has received a total of 592,059 adverse event reports across all supplements, but a specific report count for this product is not available. For calcium specifically, 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].
Our recommendation
Our recommendation is to exercise caution. Calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Because data on the St. John’s Wort, Ginseng, and Ginkgo components is not available, we cannot assess the full safety profile of this combination product. You should speak with your doctor before starting this supplement [NIH ODS].
