Solgar Megasorb Vitamin B12 5000 mcg
Brand: Solgar · Form: SUPPLEMENT FORM, OTHER [E0172] On Market
Our assessment
The evidence shows that calcium is a critical mineral for bone health, but supplementing with high doses requires careful consideration. For most adults, the goal is to meet, not exceed, the RDA through diet and targeted supplementation. For a product like Solgar Megasorb Vitamin B12 5000 mcg, which contains only vitamin B12, calcium is not a relevant ingredient. Our assessment of calcium specifically: it is essential, but more is not always better.
How it works
Think of calcium as a structural builder and a cellular messenger. It supports bone density and mineral deposition through a process called bone mineralization, and it helps your muscles relax and your nerves signal properly through neuromuscular relaxation [NIH ODS]. Your body tightly regulates calcium levels, so getting the right amount is key for these daily functions.
Safety profile
Data not available for this specific product. However, FDA has received a total of 592,059 adverse event reports across all dietary supplements. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer, while very high blood levels can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS].
Our recommendation
We recommend you get your calcium needs assessed by a healthcare professional before starting any supplement. If you are taking medications like bisphosphonates, tetracycline or fluoroquinolone antibiotics, levothyroxine, or phenytoin, be aware that calcium can reduce their absorption [NIH ODS]. For the Solgar Megasorb Vitamin B12 5000 mcg product, its purpose is B12 supplementation, not calcium, so these calcium-specific cautions do not apply to that product.
