Herb Pharm Usnea

Our assessment
The evidence shows that the primary ingredient in this product is calcium, a mineral essential for bone health and nerve function. However, the data on the specific Herb Pharm Usnea product is limited, and we must rely on the ingredient-level information available. Our assessment is that while calcium is a well-studied nutrient, you should approach this supplement with caution due to potential risks at high intakes [NIH ODS].
How it works
Calcium acts as a master regulator for your body's structural and signaling systems. It supports bone mineralization, helping to maintain bone density, and it is critical for neuromuscular relaxation, which allows your muscles to relax and your nerves to transmit signals properly [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports across all supplements, but specific side effect counts for this product are not available. For calcium specifically, high intakes may 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]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
We recommend you consult with your healthcare provider before taking this supplement, especially if you are on any medications that interact with calcium. Do not exceed the recommended daily allowance without medical supervision. Data not available on the specific dosage or efficacy of the Herb Pharm Usnea product itself [NIH ODS].
