Herb Pharm Cramp Bark
Brand: Herb Pharm · Form: LIQUID, SUPPLEMENT FORM [E0165]
Our assessment
The evidence shows that the active ingredient in this product, calcium, plays a well-established role in bone health and nerve function [NIH ODS]. However, data for the specific "Cramp Bark" extract is not available in the provided information, so we must focus on the calcium content. Our assessment is that while calcium is essential, relying on this product for muscle cramp relief is not supported by the specific data provided for this formulation.
How it works
Calcium supports neuromuscular relaxation and helps your muscles and nerves signal properly [NIH ODS]. Think of it as a key regulator for muscle contraction and relaxation. The product's name suggests a benefit for muscle cramps, but the provided data does not include any clinical studies on "Cramp Bark" itself for this purpose.
Safety profile
FDA received 592,059 total adverse event reports for all supplements, but specific side effect counts for this product are not available. For calcium, high intakes may increase the risk of heart disease and prostate cancer [NIH ODS]. High blood calcium levels can cause poor muscle tone, poor kidney function, constipation, nausea, weight loss, extreme tiredness, and abnormal heart rhythms [NIH ODS]. Calcium can also reduce absorption of medications like bisphosphonates, tetracycline antibiotics, and levothyroxine [NIH ODS].
Our recommendation
We recommend you do not rely on this product for treating muscle cramps based on the data provided. If you are considering it for calcium, get your intake from food first. If you take calcium supplements, keep your total daily intake (from food and supplements) at or below the Tolerable Upper Intake Level. Always separate calcium supplements from other medications by at least 2 hours [NIH ODS]. Consult your doctor before starting any new supplement.
