Crystal Star Men's Libido
Brand: Crystal Star · Form: CAPSULE [E0159] On Market
Our assessment
The evidence shows that Crystal Star Men's Libido contains the mineral calcium. While calcium is essential for several bodily functions, there is no clinical data in the provided information to support its use specifically for male libido. The data provided does not include any studies on this product or its combination of ingredients for this purpose.
How it works
Calcium is a mineral primarily known for its role in bone mineralization and neuromuscular relaxation, helping to support bone density and nerve signaling [NIH ODS]. This mechanism is not directly linked to libido enhancement in the data provided.
Safety profile
FDA has received a total of 592,059 adverse event reports for all dietary supplements. For calcium specifically, the data warns that high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Side effects from very high calcium levels can 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]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Data on side effects specifically for this product is not available.
Our recommendation
Based on the data provided, we cannot recommend Crystal Star Men's Libido for enhancing male libido. The primary ingredient, calcium, has a well-documented role in bone health but no demonstrated effect on libido in the available information. You should speak with your healthcare provider before taking this supplement, especially if you take any of the medications that interact with calcium [NIH ODS]. If you are concerned about your libido, a consultation with a medical professional is the most appropriate next step.
