If you’ve been in a gym environment, you’ve probably heard the term testosterone booster at one point or another. While there are diverging opinions on it — with one group of people treating it as a classic snake-oil scam, there are also numerous people vouching for its benefits, so it becomes increasingly hard to situate oneself.
The truth is that certain manufacturers are essentially producing garbage supplements, including testosterone boosters. This is either because they’re using novel ingredients with no scientific backing, or they’re just not using the optimal dosages.
To help you find a good vegan testosterone supplement, we’ve primarily looked at supplements that don’t contain ingredients like Vitamin D3 (derived from lanolin), or capsules made from gelatin.
We’ve also researched which ingredients contribute to an increase in testosterone production and made sure to find testosterone boosters that contain those ingredients served in an appropriate dose.
Here is a quick table previewing the best supplements we found:
Centra Peak
