Natural Factors Liver Health Formula
Brand: Natural Factors · Form: CAPSULE [E0159] On Market
Our assessment
The evidence shows that the Natural Factors Liver Health Formula contains calcium, a mineral important for bone health, but the data available does not support a specific benefit for liver health. Our assessment is that this product’s primary active ingredient is calcium, and any health effects would be related to that mineral. You should not expect this formula to directly support liver function based on the provided data.
How it works
Calcium works in your body through several mechanisms. It is critical for bone mineralization, helping to build and maintain bone density. It also supports neuromuscular relaxation, meaning it helps your muscles relax and your nerves signal properly [NIH ODS]. There is no data provided that explains how this formula specifically targets liver health.
Safety profile
FDA received a total of 592,059 adverse event reports for all products across all categories, but the specific number of reports for this product is not available. Regarding calcium, high levels in the blood and urine can cause side effects including poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, and abnormal heart rhythms [NIH ODS]. High calcium intakes might also increase the risk of heart disease and prostate cancer [NIH ODS].
Our recommendation
Based on the data provided, we cannot recommend this product for liver health because no evidence was supplied to support that claim. If you are considering a calcium supplement, be aware that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. You should discuss any new supplement with your healthcare provider, especially if you take prescription medications.
