How can I increase my erections with supplements

To potentially enhance erection quality through supplements, there are specific options mentioned by Andrew Huberman and Dr. Kyle Gillett during a discussion in the Huberman Lab:

1. Vitamin D: It also acts as a hormone (sterile hormone) and can help optimize testosterone levels if you are deficient in this vitamin.
2. Boron: Useful for those with high Sex Hormone Binding Globulin (SHBG) levels, boron can acutely lower SHBG, usually effective in doses ranging from 5 to 12 milligrams per day. This can help increase the amount of free testosterone available for biological effects. However, this effect is not sustained long-term.

It is also mentioned that the ideal level of free testosterone in males should be about 2% of one's total testosterone. Both supplements can influence hormone levels, potentially affecting factors like libido and energy, which in turn could improve erectile function 1.

Always consult your healthcare provider before starting any supplement regimen to ensure it is appropriate for your health condition and needs.
