Nature's Answer Eyebright Herb
Brand: Nature's Answer · Form: LIQUID, SUPPLEMENT FORM [E0165]
Our assessment
The evidence shows that eyebright herb is not a standardized supplement with a well-defined mechanism. Data on this specific ingredient is limited, and we cannot make a strong efficacy claim based on the information provided. For general health, you should focus on nutrients with robust clinical backing.
How it works
While the product is labeled as eyebright herb, the only ingredient data available is for calcium. Calcium supports bone mineralization by aiding bone density and mineral deposition, and it also promotes neuromuscular relaxation for proper nerve signaling [NIH ODS].
Safety profile
The FDA has received a total of 592,059 adverse event reports across all supplement categories [FDA data]. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer. High blood levels can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Data for eyebright-specific side effects is not available.
Our recommendation
We recommend you prioritize calcium from food sources or a standard calcium supplement if needed, as eyebright herb lacks sufficient evidence for specific health benefits. Be aware that calcium can reduce absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Always consult your pharmacist or doctor before starting this product.
