Metagenics Meta-Sitosterol 2.0
Brand: Metagenics · Form: TABLET [E0155]
Our assessment
The evidence shows that Metagenics Meta-Sitosterol 2.0 contains calcium, a mineral essential for bone health. For you, the key is understanding both the benefits and the specific risks associated with calcium supplementation. Data on the exact amount of calcium in this product is not available on the label provided, so you should check the bottle for the precise dosage per serving [NIH ODS].
How it works
Think of calcium as a structural building block for your skeleton. It supports bone mineralization and density, which is critical for preventing fractures as you age. Additionally, calcium plays a role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly after contraction [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports across all supplement categories. For calcium specifically, 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 [FDA data] [NIH ODS].
Our recommendation
Start by determining your total daily calcium intake from food and other supplements. Do not exceed the tolerable upper intake level of 2,500 mg per day for adults. Calcium can reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin, so take this supplement at least 2 hours apart from those drugs [NIH ODS].
