The 4X extract capsules took several hours to digest. I tried one cap with a meal and even 32 oz of water. Unfortunately, the capsules were not compatible with my system. However, I am giving this rating 4 stars, as my Customer Service Representative, Tobe, was extremely helpful in resolving my concerns, in exchange for Black Seed Oil SOFT GEL caps. So far, with taking the soft gels, I am extremely satisfied!
