Herb Pharm Hydrangea
Brand: Herb Pharm · Form: LIQUID, SUPPLEMENT FORM [E0165]
Our assessment
The evidence shows that Hydrangea has a traditional history of use, but for the specific ingredient Calcium, the data is clear. Calcium is essential for bone health, but supplementation requires careful consideration of your overall diet and health status. Our assessment is that while calcium is critical, you should only supplement if you cannot meet the RDA through food, as high intakes carry significant risks [NIH ODS].
How it works
Think of calcium as a structural builder for your bones. It supports bone mineralization and density, and it also plays a key role in neuromuscular relaxation and nerve signaling [NIH ODS]. Your body maintains a very tight control over calcium levels in your blood, pulling it from your bones if your dietary intake is low.
Safety profile
FDA received a total of 592,059 adverse event reports across all supplement categories. For calcium specifically, the risks are significant at high intakes. Some research suggests that high calcium intakes might increase the risk of heart disease and prostate cancer. High levels of calcium in the blood and urine can cause 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]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
We recommend that you first assess your dietary calcium intake from foods like dairy, leafy greens, and fortified products. If you are considering a supplement, do not exceed the RDA without a healthcare provider’s guidance due to the serious risks associated with high intake [NIH ODS]. If you take any of the listed medications, separate your calcium supplement by at least 2 hours to avoid absorption issues. Data not available for specific interactions with Hydrangea [NIH ODS].
