Carlson L-Lysine Amino Acid Powder
Brand: Carlson · Form: POWDER [E0162]
Our assessment
The evidence shows that L-lysine is an essential amino acid, but the data provided here is for calcium, not lysine. Based on the specific data available, we cannot assess L-lysine directly. For the ingredient calcium found in some formulations, the data confirms it supports bone mineralization and neuromuscular relaxation [NIH ODS]. However, you should be aware that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS].
How it works
Think of calcium as a structural and signaling mineral — it supports bone density through mineral deposition and helps your muscles relax and nerves signal properly [NIH ODS]. Data on how L-lysine specifically works is not available in the provided information.
Safety profile
Data on adverse events for L-lysine specifically is not available. For calcium, FDA received a total of 592,059 adverse event reports across all supplements. Side effects from high calcium levels include 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] [FDA data]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Because the provided data focuses on calcium rather than L-lysine, a specific recommendation for this product is not possible from the given information. If you are taking this product for its calcium content, be cautious about total intake from all sources and consult your doctor, especially if you take any of the listed medications [NIH ODS]. For L-lysine’s specific effects and safety, data is not available in this report.
