Michael's Naturopathic Programs Testosterone Factors

Our assessment

The evidence shows that this product contains calcium, a mineral essential for bone health and nerve function [NIH ODS]. However, we cannot verify the specific benefits of "Testosterone Factors" because data on the full formula and its effects on testosterone are not provided. Our assessment is that calcium is a well-studied nutrient, but its role in testosterone support is not established by the data we have.

How it works

Calcium plays a critical role in your body as a structural component for bones and teeth, a process called bone mineralization [NIH ODS]. It also supports neuromuscular relaxation, meaning it helps your muscles relax and your nerves send signals properly [NIH ODS]. Think of calcium as a key messenger that helps your muscles and nerves communicate effectively, but this mechanism is not directly linked to testosterone production based on the information available.

Safety profile

The FDA has received a total of 592,059 adverse event reports across all supplements, though specific reports for this product are not available [FDA data]. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer [NIH ODS]. 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]. Calcium can also reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].

Our recommendation

We recommend you speak with your healthcare provider before taking this supplement, particularly if you have a history of kidney stones, heart disease, or take prescription medications. Data on the specific testosterone claims is not available, so we cannot support using this product for that purpose. If you choose to take it, monitor for side effects like nausea or constipation [NIH ODS].
