The benefits of the Reishi mushroom develop gradually, rather than providing instant effects. It does not have the electric effects of stimulants, which work instantaneously. Rather, it works slowly, as the compounds build up in your system. Most users experience the benefits of improved energy and immunity within 4 to 6 weeks of regular use at proper dosages.

A number of factors will determine how fast the effects are felt. Your metabolism, digestive health, and the quality of your dosage can all affect the absorption rate. Taking the reishi on an empty stomach can improve bioavailability, but other medications may reduce the impact of the reishi. Differences in individual biochemistry create natural variation.

For best results, maintain consistency every day and establish a routine that suits your lifestyle. This will allow you to fully appreciate the many subtle improvements you may experience. Perhaps you will find that your sleeping patterns become more restful or that you no longer suffer from the dreaded afternoon slump. Patience is all-important with this adaptogen, whose weighty yet gentle cumulative action will yield gradual rather than immediate results.
