Nature's Sunshine Free Amino Acids with Magnesium & L-Carnitine
Brand: Nature's Sunshine · Form: TABLET [E0155]
Our assessment
The evidence shows that this supplement provides calcium, a mineral essential for bone health and nerve function. However, the specific amounts of calcium, magnesium, and L-carnitine in this product are not detailed in the data we have, which limits our ability to give a precise recommendation. We can only speak to the role of calcium based on the information provided [NIH ODS].
How it works
Think of calcium as a structural building block for your bones and a signal messenger for your nervous system. It supports bone mineralization and density, and it is critical for muscle relaxation and nerve signaling [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports for all supplements combined. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer. Very high blood levels can lead to poor muscle tone, poor kidney function, constipation, nausea, weight loss, extreme tiredness, and abnormal heart rhythms [NIH ODS]. Calcium can also reduce the absorption of medications like bisphosphonates, tetracycline and fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
If you are considering this product, check the label for exact amounts of each ingredient. Be cautious with total calcium intake from all sources (food and supplements), as high levels carry risks [NIH ODS]. If you take any of the listed medications, separate your calcium dose by at least two hours. Always consult your doctor before starting a new supplement.
