Higher Nature Nails & Hair
Brand: Higher Nature · Form: CAPSULE [E0159] On Market
Our assessment
Our assessment: The evidence shows that calcium supports bone health and neuromuscular function, but the data for using this specific supplement to improve nail and hair strength is limited [NIH ODS]. For you to see a benefit, your diet would likely need to be deficient in this mineral first.
How it works
Think of calcium as a structural building block for your body. It is best known for bone mineralization, helping to support bone density and mineral deposition, and it also plays a role in neuromuscular relaxation, supporting muscle relaxation and nerve signaling [NIH ODS]. While nails and hair contain trace minerals, calcium's primary role is not in their growth or strength.
Safety profile
FDA received a total of 592,059 adverse event reports across all supplements. For calcium specifically, safety data notes that some research suggests high intakes might increase the risk of heart disease and prostate cancer. High levels 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
Our recommendation: Do not take this supplement unless you have a confirmed calcium deficiency. The data does not support its use for nail and hair health specifically. If you are considering it, check with your doctor about medication interactions and have your blood calcium levels tested first [NIH ODS].
