Source Naturals Amino Muscle
Brand: Source Naturals · Form: CAPSULE [E0159]
Our assessment
Our assessment: The evidence shows that Source Naturals Amino Muscle is a supplement containing calcium as a key ingredient. For general health, calcium is essential for bone mineralization and neuromuscular relaxation [NIH ODS]. However, the data available for this specific product is limited, so we must focus on the ingredient with published data.
How it works
Think of calcium as a structural builder and signal messenger. It supports bone density by depositing into your skeleton, and it helps your muscles relax and your nerves send signals properly [NIH ODS]. These functions are vital for daily movement and overall cellular communication.
Safety profile
The FDA has received 592,059 total adverse event reports for all supplements, but specific report counts for this product are not available. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer. 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]. Calcium can also reduce absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
We recommend you check the label for the exact calcium dosage per serving. If you are taking any medications listed above, take this supplement at least two hours apart from them. Start with the lowest effective dose and monitor for side effects like constipation or nausea. Data not available for other ingredients in this product, so consult your healthcare provider before use [NIH ODS].
