Our assessment

The evidence shows that this product, HoltraCeuticals Iron Rx, contains calcium as its identified ingredient. Our assessment is that while calcium is essential for bone health, the specific benefits and risks of this particular supplement depend entirely on your individual calcium intake from diet and other supplements. The data provided does not specify the exact dose of calcium in this product, which is a critical piece of information for making a safe recommendation [NIH ODS].

How it works

Calcium acts as a master regulator in your body. It supports bone density and mineral deposition through a process called bone mineralization, and it also plays a key role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly [NIH ODS].

Safety profile

Data not available for specific side effects of this product. However, the FDA has received a total of 592,059 adverse event reports across all supplements. For calcium generally, some research suggests that high 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] [FDA data].

Our recommendation

Before taking this supplement, you should first determine your daily calcium needs from food and other supplements. The product label is missing a specific dose, so you cannot assess your total intake. Also, be aware that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Our recommendation is to consult with your healthcare provider to see if this supplement is appropriate for you, given the lack of specific dosage information and potential for interactions.
