Metabolic Maintenance Vitamin D-3
Brand: Metabolic Maintenance · Form: CAPSULE [E0159] On Market
Our assessment
The evidence shows that this product is a straightforward vitamin D-3 supplement. The primary ingredient, calcium, is well-documented for its role in bone health, but you should be aware that this product appears to contain calcium, not vitamin D-3 as the name suggests. The data provided does not confirm the vitamin D-3 content. Our assessment is that you should verify the label to ensure this product meets your specific needs, as the core benefits and risks are tied to calcium [NIH ODS].
How it works
Think of calcium as a structural building block for your skeleton. It supports bone mineralization and density by depositing into your bone matrix. Additionally, it plays a key role in neuromuscular relaxation, meaning it helps your muscles relax and your nerves signal properly after they contract [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports across all products. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. Excess calcium in your 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
Start by checking the product label to confirm it contains vitamin D-3, as the data only specifies calcium content. If you are taking medications, be aware that calcium can reduce absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Do not exceed recommended doses to avoid the serious side effects listed above. Data not available for specific vitamin D-3 benefits or dosing from this product.
