Douglas Laboratories Microbiome Fiber
Brand: Douglas Laboratories · Form: POWDER [E0162]
Our assessment
The evidence shows that Douglas Laboratories Microbiome Fiber contains Calcium as a key ingredient. Calcium is well-supported for bone health, but our assessment is that you need to be cautious about the total amount you are taking from all sources, as the data shows high intakes carry significant risks [NIH ODS].
How it works
Think of calcium as a structural building block for your skeleton. It supports bone mineralization and density, and also plays a role in neuromuscular relaxation and nerve signaling [NIH ODS]. However, for a product labeled as a microbiome fiber, the primary mechanism for gut health is not provided in the data.
Safety profile
FDA received 592,059 total adverse event reports across all supplements. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer. High blood and urine 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] [FDA data]. Calcium can also reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Data not available on a specific recommended dose for this product. We recommend you check the label for the exact amount of calcium per serving. To stay safe, do not exceed the daily upper limit from all supplements and food combined. Always take calcium supplements with food and separate them from the medications listed above by at least 2 hours [NIH ODS].
