Brand: Herb Pharm · Form: LIQUID, SUPPLEMENT FORM [E0165]
Our assessment
The evidence shows that Black Haw is a botanical supplement, and our assessment must be based on the data available for its primary ingredient, Calcium. For general bone and muscle health, Calcium is well-supported, but specific claims for Black Haw as a standalone product are limited by the data provided. You should approach this supplement with realistic expectations about its proven benefits.
How it works
Calcium works through a dual mechanism: it supports bone mineralization by helping deposit minerals into your skeleton, and it promotes neuromuscular relaxation by assisting in nerve signaling and muscle relaxation [NIH ODS]. Think of it as a key player in keeping your bones dense and your muscles functioning smoothly.
Safety profile
The FDA has received a total of 592,059 adverse event reports across all supplements. For Calcium specifically, high intakes may increase the risk of heart disease and prostate cancer. Side effects from excessive calcium include constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS] [FDA data]. Data on side effects specific to Black Haw is not available.
Our recommendation
If you are considering Black Haw for its Calcium content, be aware that Calcium can reduce the absorption of certain medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Start with a low dose and consult your doctor, especially if you take any of these medications. Data not available for a specific dose recommendation for Black Haw.
