Herb Pharm Rhubarb
Brand: Herb Pharm · Form: LIQUID, SUPPLEMENT FORM [E0165]
Our assessment
The evidence shows that the primary active ingredient in Herb Pharm Rhubarb (based on available data) is calcium. Our assessment: calcium is a well-studied mineral essential for bone health, but the specific product “Herb Pharm Rhubarb” has very limited data on its own effectiveness or safety. Data on the specific herbal preparation and its intended benefits is not available. We must rely on general calcium data, but this does not confirm that the product provides any therapeutic benefit.
How it works
Calcium acts as a master regulator for your body. It supports bone mineralization and density, and it helps with neuromuscular relaxation by aiding nerve signaling and muscle function [NIH ODS]. Think of it as a key building block for your skeleton and a calming signal for your nerves.
Safety profile
FDA received 592,059 total adverse event reports across all supplements, but specific side effect counts for this product are not available. For calcium in general, high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. 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]. Calcium can also reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Do not rely on this product for calcium supplementation without consulting your doctor. Data not available on the specific benefits or risks of the rhubarb preparation itself. If you need calcium, choose a standard supplement with known dosing and third-party testing. Always check with your pharmacist about potential interactions with your medications [NIH ODS].
