If you're looking for natural digestive comfort — specifically occasional heartburn and reflux relief — **D-Limonene** is a terpene compound from citrus peel with limited but targeted clinical research. At 250mg per softgel, you're getting a dose that falls within the range used in the few available studies, though the evidence base is quite small compared to well-studied digestive supplements.
The formula is straightforward — just D-limonene from orange peel in an MCT oil base with a standard gelatin softgel. What this means for you: one capsule daily with food keeps it simple, and the oil-based delivery may help with absorption since D-limonene is fat-soluble.
The biggest limitation is the evidence itself. There are very few human clinical trials on D-limonene for any health outcome, and the existing studies are small and not well-replicated. If you're looking for well-researched digestive support, the clinical backing here is thin. This is more of an emerging ingredient than an established one.
