Natural Factors Liver Health Formula
Brand: Natural Factors · Form: CAPSULE [E0159]
Our assessment
The evidence shows that this product contains calcium, which is a well-studied mineral for bone health. However, the data we have is for calcium alone, not the specific "Natural Factors Liver Health Formula." We cannot assess the full formula, but we can provide guidance on the calcium component. For most adults, the RDA for calcium is 1,000 mg daily, but this product's exact dosage is not available in the data provided [NIH ODS].
How it works
Think of calcium as a structural building block for your skeleton. It supports bone mineralization and density, and it also plays a role in neuromuscular relaxation and nerve signaling [NIH ODS]. For a liver health formula, calcium is not typically the primary active ingredient, so its role here may be supportive rather than therapeutic for liver function.
Safety profile
The FDA received a total of 592,059 adverse event reports across all supplements in the database, though specific reports for this product are not available. For calcium specifically, high intakes can increase the risk of heart disease and prostate cancer. Side effects from high calcium levels include 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 and fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Data not available for the complete formula, so we cannot give a specific recommendation for this product. If you are considering it, consult your healthcare provider first, especially if you take any of the medications listed above. For general calcium needs, getting calcium from food sources is often preferred, and supplementation should be based on your dietary intake and medical advice [NIH ODS].
