Indiana Botanic Gardens Calcium 600 With Vitamin D

Our assessment

The evidence shows that this product combines two well-studied nutrients, but the data has important limitations. We can evaluate the ingredients individually, but specific information on this exact product is limited. The primary ingredient, calcium, is essential for bone health, but you need to be cautious about dosing and potential risks [NIH ODS].

How it works

Think of calcium as a structural builder for your bones. It supports bone density and mineral deposition, which is critical for maintaining skeletal strength as you age. Additionally, calcium plays a role in neuromuscular relaxation, helping your muscles relax and nerves signal properly [NIH ODS]. Vitamin D, included in this formulation, helps your body absorb the calcium you consume [NIH ODS].

Safety profile

Data not available for this specific product from the FDA database. However, the FDA received a total of 592,059 adverse event reports across all supplement categories, but no specific side effect counts for this product are provided. For calcium itself, 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]. You should also know that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].

Our recommendation

Start by checking your total calcium intake from food and other supplements to avoid exceeding recommended limits. Take this supplement with food for best absorption. If you take any of the medications listed above, separate your calcium dose by at least two hours [NIH ODS]. Given the potential heart disease and prostate cancer risks with high intakes, do not exceed the recommended dosage on the label without consulting your doctor [NIH ODS].
