Brand: Herb Pharm · Form: LIQUID, SUPPLEMENT FORM [E0165]
Our assessment
The evidence shows that the product Herb Pharm Periwinkle has no specific data available on its ingredients or benefits. However, the data provided includes information on calcium, which is a separate ingredient not listed in this product. For calcium, the evidence shows it supports bone density and muscle relaxation [NIH ODS]. You should be aware that no studies or data are available for periwinkle itself in the provided information.
How it works
Think of calcium as a structural builder — it supports bone mineralization and helps with nerve signaling for muscle relaxation [NIH ODS]. This mechanism is relevant only to calcium, not to periwinkle, as data for periwinkle is not available.
Safety profile
Data not available for Herb Pharm Periwinkle. The FDA received 592,059 total adverse event reports across all supplements in the data set [FDA data]. For calcium specifically, side effects include constipation, nausea, weight loss, and abnormal heart rhythms at high levels [NIH ODS]. No side effect report count is available for periwinkle.
Our recommendation
Because no data is available on the ingredients or safety of Herb Pharm Periwinkle, you should consult your healthcare provider before taking this supplement. For general bone health, evidence supports calcium, but this product does not list calcium as an ingredient based on the data provided [NIH ODS].
