How much zinc should I take to boost testosterone?
Most studies suggest 15-30mg of zinc daily can support healthy testosterone levels in men over 35. However, it's best to consult with your doctor to determine the right dosage for you.
Can I get enough zinc from my diet?
While foods like oysters, beef, and pumpkin seeds are good sources of zinc, it can be challenging to get enough consistently through diet alone. Supplementation can help ensure adequate intake.
What are the side effects of taking too much zinc?
Excessive zinc intake can lead to nausea, vomiting, stomach cramps, and diarrhea. Long-term overconsumption can also interfere with copper absorption, so stick to recommended dosages.
