Mason Natural Super Calcium 600 + D3 400

Brand: Mason Natural · Form: TABLET [E0155] On Market

Our assessment

The evidence shows that Mason Natural Super Calcium 600 + D3 400 is a straightforward supplement designed to support bone health. The primary ingredient, calcium at 600 mg per serving, plays a critical role in bone mineralization and neuromuscular function [NIH ODS]. For most adults, this provides a meaningful portion of the daily recommended intake, but you should be aware of your total calcium consumption from all sources. Data on the specific D3 content (400 IU) is not available in the provided data, so we cannot assess its adequacy here.

How it works

Think of calcium as a building block for your skeleton. It works through bone mineralization, helping deposit minerals into bone tissue to maintain density and strength [NIH ODS]. Additionally, calcium supports neuromuscular relaxation, which is essential for proper muscle function and nerve signaling [NIH ODS]. This makes the supplement relevant not just for bone health, but also for basic muscle and nerve performance.

Safety profile

Safety is a key consideration. The FDA has received a total of 592,059 adverse event reports across all supplements, but specific report counts for this product are not available [FDA data]. Regarding calcium itself, high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Very high levels can cause constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. You should also be aware that calcium can reduce the absorption of medications such as bisphosphonates, tetracycline and fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Take this supplement at least 2 hours apart from those medications.

Our recommendation

This supplement can be a reasonable choice for supporting your bone health, provided you are not exceeding your total daily calcium needs from food and other supplements. Start by reviewing your diet. If you already consume dairy, fortified foods, or other calcium-rich items, this 600 mg dose may push you too high. Monitor for side effects like constipation or nausea. If you take any of the listed medications, separate your doses. For personalized advice, consult your healthcare provider to check your calcium and vitamin D levels.
