Brand: The Vitamin Shoppe · Form: CAPSULE [E0159]
Our assessment
The evidence shows that this product combines 5-HTP with vitamin B6, but our assessment is based on the data provided for its calcium content. We must be transparent: the provided data does not include specific information on 5-HTP, vitamin B6, or the product's specific effects. For calcium, the data supports its role in bone health, but you should be aware of significant safety considerations before taking this or any supplement [NIH ODS].
How it works
Think of calcium as a structural and signaling powerhouse. It supports bone mineralization and density, and is critical for neuromuscular relaxation and nerve signaling. The data indicates it helps your muscles relax and your nerves communicate properly [NIH ODS].
Safety profile
The FDA has received a total of 592,059 adverse event reports across all supplements. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. High blood and urine levels of calcium can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS] [FDA data].
Our recommendation
Data not available for a specific recommendation on this product's 5-HTP or B6 content. For the calcium component, you should be cautious: it can reduce absorption of medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. We recommend consulting your physician before starting this supplement, especially if you take any of these medications or have a history of kidney or heart conditions.
