Brand: SmarterVitamins · Form: SOFTGEL CAPSULE [E0161] On Market
Our assessment
Our assessment: The evidence for this supplement is limited. While calcium is an essential mineral for bone health, the data provided shows no specific benefits for the combination of 5-HTP and Vitamin B6 in this product [NIH ODS]. You should be aware that the core ingredient with available data here is calcium, which supports bone mineralization and neuromuscular relaxation [NIH ODS].
How it works
Think of calcium as a structural building block for your bones and a regulator for your nerves and muscles. It supports bone density through mineralization and helps your muscles relax after contraction [NIH ODS]. Data not available for the specific mechanisms of 5-HTP or Vitamin B6 in this formulation.
Safety profile
The FDA has received 592,059 total adverse event reports across all supplements. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer [NIH ODS]. High levels in your blood and urine 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]. Calcium can also reduce absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Our recommendation: Because data for 5-HTP and Vitamin B6 is not available in the provided information, you should be cautious with this product. If you choose to take it, be aware of calcium’s interactions with other medications and the risk of side effects at high doses [NIH ODS] [FDA data]. Consult your doctor before starting, especially if you take any antibiotics, thyroid medication, or have a history of kidney problems.
