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 Calcium as an ingredient, but data on its effectiveness for male libido is not available. Our assessment: based on the provided data, this product's only identified ingredient is Calcium, which has a well-established role in bone health, not libido support. You should not expect this product to improve sexual function or desire based on the information provided.
How it works
Calcium supports bone mineralization and neuromuscular relaxation [NIH ODS]. Think of it as a key mineral for structural strength and nerve signaling, not for libido or sexual health. The mechanism does not target hormonal pathways or blood flow related to sexual function.
Safety profile
The FDA has received 592,059 total adverse event reports for all supplements, but specific data for this product is not available. For calcium, high 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 reduce absorption of medications including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Data not available for this product's effectiveness for men's libido. Our recommendation: do not rely on this product for sexual health. For bone health, calcium is well-supported, but you should get your levels checked before supplementing. Always discuss any supplement with your healthcare provider, especially if you take prescription medications that interact with calcium [NIH ODS].
