I’ve blogged about the Sleep promoting effects of combined GABA and 5-HTP. There is another combination of nutrients that has been shown to help with sleep: GABA and the herb Apocynum venetum leaf extract.
In this 2015 paper: The Improvement of Sleep by Oral Intake of GABA and Apocynum venetum Leaf Extract
The electroencephalogram (EEG) test revealed that oral administration of GABA (100 mg) and [Apocynum venetum Leaf Extract] AVLE (50 mg) had beneficial effects on sleep.
In this study they found that GABA helps people to fall asleep quickly and Apocynum venetum Leaf Extract induces deep sleep, and that they work well when taken together.
The authors conclude that both GABA and Apocynum venetum leaf extract:
can be regarded as safe and appropriate for daily intake in order to improve the quality of sleep.
Earlier this year I heard Dr. Peter Bongiorno present at the Integrative Healthcare Symposium and one of the herbs he covered was Apocynum venetum leaf extract for depression. Since this was new to me, I invited him to share about this herb on the recent Anxiety Summit: Serotonin and anxiety: tryptophan, 5-HTP, serotonin syndrome and medication tapers
I also briefly mentioned the above GABA/Apocynum venetum leaf extract study in my talk on the recent Anxiety Summit – GABA: Blood brain barrier controversy, concerns, best forms and how to do a trial for eliminating anxiety
I find that many of my clients with anxiety also have sleep problems and GABA is often helpful if their sleep issues are related to low GABA levels, often manifesting as physical tension.
One of the signs of low serotonin, in addition to anxiety and worry, is insomnia and I find tryptophan (and sometimes 5-HTP) to be very helpful for many clients too. I’ll often have someone use both GABA and tryptophan (or GABA and 5-HTP) and the combination seems to be a good one.
I have not yet used Apocynum venetum leaf extract alone with clients or in combination with GABA and look forward to learning more. Have you have tried it alone or in combination with GABA? Have you used it with clients?
