In most cases we do not recommend combining lucid dreaming supplements, at least at first. You really need to know what actually helped you achieve lucid dreaming success, and combining things only muddies that water. You end up having to take that same combination over and over in order to replicate that success, even though only one of them truly worked. This can be both expensive and unnecessary, and that is why our usual advice is to only combine when you’ve taken each lucid dreaming supplement individually for a little while at least first.
However, in some cases there are exceptions to this rule, and there are a few lucid dreaming supplement combinations that are not only worth taking from the start, but also reported to only work well in these combinations. In other words, in a few cases the lucid dreaming supplements work in tandem, and that is how they should be taken for maximum effect. The most well-known example of this is the combination of Galantamine and Choline. Choline is a water-soluble vitamin that is part of the B-complex vitamins. Alone some people find that Choline does very little when it comes to helping you achieve lucid dreams, but in combination with Galantamine there can be a strong effect. Choline seems to increase the lucid dream promoting action of Galantamine. In fact, many preparations of Galantamine include choline.
A step further, there appears to be another chemical that can be used in combination with the above two that makes this preparation an even stronger lucid dreaming supplement. Alpha-GPC is taken by some who feel it improves memory and learning. But in combination with Galantamine and Choline, Alpha-GPC may help you achieve lucid dreaming success.
