Brand: Nature's Sunshine · Form: TABLET [E0155] On Market
Our assessment
The evidence shows that this product combines amino acids with calcium and L-carnitine, but the data we have is limited to the calcium component. Our assessment: you should understand that the benefits and risks here are based on the calcium content, as specific data for the full blend is not available.
How it works
Think of calcium as a key structural support for your body. It supports bone density and mineral deposition, and also helps with neuromuscular relaxation and nerve signaling [NIH ODS]. The amino acids and L-carnitine in this formula are intended to support muscle function and energy metabolism, though specific data for these ingredients in this product is not available.
Safety profile
Safety data is based on the calcium ingredient. Some research suggests that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. 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 [NIH ODS]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. The FDA has received 592,059 total adverse event reports across all supplements, but specific report counts for this product are not available [FDA data].
Our recommendation
Before taking this supplement, review your total calcium intake from food and other supplements to avoid exceeding safe levels. If you take any medications listed above, separate calcium intake by at least 2 hours to prevent absorption issues [NIH ODS]. Data not available for the specific benefits of the amino acid and L-carnitine blend in this product, so consult your healthcare provider for personalized advice.
