No supplement is intended to treat, cure, or prevent disease.
Here’s what the latest research suggests about the potential benefits of D-asp.
A systematic review concluded that D-aspartic acid supplements may only increase testosterone in males with low baseline levels.
Fertility
D-asp may improvefertility, but more data is necessary.
More robust clinical trials are necessary before D-aspartic acid can be routinely recommended for fertility.
Discuss treatment options with your healthcare provider if this concerns you.
Schizophrenia
Early research suggests that D-aspartic acid helped reduce symptoms in people with treatment-resistantschizophrenia.
Clinical trials in humans are necessary to confirm these effects.
Keep in mind that mental health conditions like schizophrenia should not be self-treated.
If not appropriately managed, quality of life and functioning could decline.
Safety
Avoid D-aspartic acid if you’re allergic to it or its components (parts).
Keep the following precautions in mind when deciding if D-aspartic acid is suitable for you.
It’s important for brain function and the endocrine system.
It’s often marketed as a testosterone booster or performance enhancer in supplement form.
Though D-aspartic acid may benefit fertility or schizophrenia, it’s too soon to know.
There’s little evidence that this supplement increases testosterone, strength, fertility, or mental health for now.
D-aspartic acid is important for nerve signaling and the release of hormones like testosterone, prolactin, and oxytocin.
More research is necessary to understand the safety of D-aspartic acid.
