Natural Factors Liver Health Formula
Brand: Natural Factors · Form: CAPSULE [E0159]
Our assessment
The evidence shows that the Natural Factors Liver Health Formula’s primary active ingredient, calcium, is a mineral essential for bone health, but dedicated data on this specific liver health formula is not available. Our assessment is based on the calcium content. While calcium supports bone mineralization and neuromuscular relaxation [NIH ODS], its role in liver health is not directly supported by the data provided. You should be aware that this product’s main claim is not backed by specific studies in the provided data.
How it works
Think of calcium as a structural building block for your bones and a signaling molecule for your muscles and nerves. It supports bone density and mineral deposition, and helps with muscle relaxation and nerve signaling [NIH ODS]. There is no data provided explaining how calcium specifically benefits the liver.
Safety profile
The FDA received a total of 592,059 adverse event reports for all supplements, but specific report counts for this product are not available. For calcium, high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Side effects from very high blood and urine levels include poor muscle tone, poor kidney function, constipation, nausea, weight loss, extreme tiredness, frequent urination, 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
Start by reviewing the product label for the exact dose of calcium, as the data provided does not specify this. Given the potential risks of high calcium intake, do not exceed the RDA without medical supervision. If you take any prescription medications, especially those listed above, space them apart from this supplement by at least two hours [NIH ODS]. Always consult your physician before starting any new supplement, especially one with a primary ingredient like calcium that has known interactions and risks.
