Herb Pharm Motherwort
Brand: Herb Pharm · Form: LIQUID, SUPPLEMENT FORM [E0165]
Our assessment
The evidence shows that Motherwort can be a helpful herb for nervous tension and heart palpitations, but the data on its active ingredient, calcium, is more robust. Our assessment: If you are looking for a supplement to support bone health and muscle relaxation, calcium is well-studied, but you should be aware of its risks and interactions [NIH ODS].
How it works
Think of calcium as a master regulator for your bones and nerves. It supports bone mineralization, helping to build and maintain strong bone density, and it also aids in neuromuscular relaxation, which means it helps your muscles relax and your nerves send signals properly [NIH ODS].
Safety profile
The FDA has received 592,059 total adverse event reports across all supplements. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. Side effects from high blood and urine calcium levels include poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS] [FDA data].
Our recommendation
Start with a moderate dose and get your blood calcium levels checked. Be aware that calcium supplements can reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin, so take them at a different time of day [NIH ODS].
