I'm here to answer questions about supplements and nutrition. If you're interested in supplements that may impact sleep or dreaming, such as melatonin or valerian root, feel free to ask!

Several supplements have been studied for their potential to enhance dream recall and vividness:

1. Vitamin B6 (Pyridoxine): Research suggests that vitamin B6 may enhance dream recall. In a study where participants took 240 mg of vitamin B6 before bed, it was found to increase the amount of dream content they recalled¹. However, it did not significantly affect the vividness, bizarreness, or color of the dreams.

2. Galantamine: This supplement, typically used to enhance cognitive function, has been shown to stimulate lucid dreaming and increase dream recall². Participants taking galantamine reported more vivid and detailed dreams.

3. Cholinergic Substances: Enhancing cholinergic neurotransmission can potentially improve dream recall and the likelihood of lucid dreams³. Galantamine is an example of such a substance.

While these supplements have shown some promise in studies, it's important to approach them with caution, considering possible side effects and individual variability in response. Always consult with a healthcare provider before starting any new supplement regimen.
