Vitamin K2 and Erectile Dysfunction

While Vitamin K2 is not a direct treatment for ED, emerging research suggests that it may support vascular health and testosterone regulation, two key factors in maintaining strong erections. Here’s how:

Erectile dysfunction is often linked to poor blood circulation due to plaque build up in arteries, a condition known as atherosclerosis [1]. Vitamin K2 prevents calcium build up in blood vessels and keeps arteries flexible for healthy circulation [2] . Since erections depend on strong blood flow, better vascular health may reduce the risk of ED.

Testosterone is essential for libido and erectile function. Some studies suggest that Vitamin K2 can help boost testosterone production by improving testicular function and reducing oxidative stress. A 2011 study in rats found that supplementing with Vitamin K2 significantly increased testosterone levels compared to a control group [3]. While human studies are limited, these findings indicate potential benefits for men with low testosterone-related ED.

Heart disease and ED share similar risk factors, including high blood pressure and poor arterial health [4]. Since Vitamin K2 is known for reducing arterial stiffness and improving heart function, it may indirectly support better erectile performance by maintaining optimal blood flow.

There is no official Recommended Daily Allowance (RDA) for Vitamin K2, but experts suggest between 100–200 mcg per day for optimal cardiovascular and bone health [5]. The best food sources include:

• Natto (fermented soybeans) – highest natural source
• Cheese (Gouda, Brie, Cheddar)
• Egg yolks
• Grass-fed meats

For those struggling to get enough from diet alone, Vitamin K2 supplements may be beneficial. However, always consult a healthcare provider before starting any new supplement.

While Vitamin K2 is not a proven ED treatment, it may help improve vascular health and testosterone levels, which can indirectly support better erectile function.
