Taylor MD Formulations Stress B Complex RX

Our assessment

The evidence shows that this product is a B-complex formulation with added calcium. Based on the data provided, calcium plays a key role in bone mineralization and neuromuscular relaxation [NIH ODS]. However, we cannot assess the specific benefits of the B-complex portion because data on those ingredients is not available. For the calcium component, you should be aware of important safety considerations.

How it works

Calcium acts as a master regulator for your bones and muscles. It supports bone density and mineral deposition, and it helps your muscles relax and your nerves signal properly [NIH ODS]. Think of it as the structural foundation for your skeleton and the calming signal for your nervous system.

Safety profile

FDA received 592,059 total adverse event reports across all supplement categories. For calcium specifically, high intakes might 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 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].

Our recommendation

We recommend you consult with your healthcare provider before starting this supplement, especially if you take any of the medications listed above. Be mindful of your total calcium intake from all sources, including food and other supplements. If you have a history of kidney stones, heart disease, or prostate cancer, discuss the risks with your doctor [NIH ODS]. Data on the B-complex portion is not available, so we cannot provide a specific recommendation for that component.
