Our assessment
The evidence shows that this product contains calcium, a mineral best known for its role in bone health. However, the data on calcium is mixed, and high intakes carry potential risks. For most people, getting calcium from food is preferable to supplements unless a deficiency is confirmed by a healthcare provider [NIH ODS].
How it works
Calcium acts as a master regulator for your body's structural and signaling systems. It supports bone density and mineral deposition, and it also plays a key role in neuromuscular relaxation and nerve signaling [NIH ODS]. Think of it as the building block for your skeleton and a helper for your muscles to relax properly.
Safety profile
The FDA has received a total of 592,059 adverse event reports across all supplement categories. For calcium specifically, some research suggests that high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. 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]. Additionally, calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Data on side effects specifically for this Genestra Brands Melatonin Spray product is not available.
Our recommendation
We recommend you do not rely on this product for calcium supplementation. The risks associated with high calcium intake are significant, and this product's primary ingredient is not calcium. If you are considering a calcium supplement, discuss your diet and blood levels with your doctor first. Always inform your pharmacist about all supplements you take to check for potential interactions with your medications [NIH ODS].
