5 Supplements to Boost Testosterone After 40
As men age, testosterone levels decline, typically by 1-2% per year after age 30. This can lead to a reduction in libido, energy levels, and muscle mass. Luckily, natural supplements can help combat this drop.
Here are five of the best testosterone-boosting supplements for men over 40.
1. D-Aspartic Acid (DAA)
D-Aspartic Acid plays a crucial role in regulating testosterone production. Research shows that DAA can boost testosterone levels by up to 42% in just two weeks. It acts by increasing luteinizing hormone (LH) and stimulating the testes to produce more testosterone.
2. Zinc
Zinc is essential for testosterone production, especially in men who engage in intense physical exercise. Studies show that zinc supplementation increases serum testosterone levels in men with zinc deficiencies.
3. Fenugreek
Fenugreek is known for its ability to increase testosterone while also reducing body fat. One study found that men taking 500 mg of Fenugreek daily for 12 weeks saw significant improvements in testosterone levels and sexual function.
4. Ashwagandha
Ashwagandha, a powerful adaptogen, has been shown to reduce cortisol levels, which directly improves testosterone levels. Men supplementing with Ashwagandha experienced a 17% increase in testosterone after 8 weeks in clinical studies.
5. Vitamin D
Low vitamin D levels are strongly associated with low testosterone. One study showed that men who took vitamin D supplements daily for a year saw a 25% increase in testosterone levels.
