Longs Wellness Calcium 600 mg

Our assessment

The evidence shows that calcium is a critical mineral for your bone health and nerve function. For this product, Longs Wellness Calcium 600 mg, the data confirms it supports bone mineralization and neuromuscular relaxation [NIH ODS]. However, you should be aware that the benefits come with specific risks and medication timing requirements.

How it works

Think of calcium as a building block — your body uses it to deposit minerals into bone tissue, keeping your skeleton strong and dense. It also plays a direct role in helping your muscles relax and your nerves send signals properly [NIH ODS]. Without enough calcium, your body will pull it from your bones to maintain these essential functions.

Safety profile

FDA received 592,059 total adverse event reports across all supplements. 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]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].

Our recommendation

Start by checking if you actually need a calcium supplement — many people get enough from diet alone. If you take this product, separate it from medications by at least 2 hours, especially thyroid medication and antibiotics [NIH ODS]. Do not exceed the recommended dose, and talk to your doctor if you have a history of kidney stones, heart disease, or prostate cancer [NIH ODS].
