The biological activity of Leucocyanidin is primarily attributed to its potent antioxidant capacity. It effectively scavenges free radicals, such as reactive oxygen species (ROS) and reactive nitrogen species (RNS), thereby protecting cellular components from oxidative damage. It can chelate metal ions that catalyze oxidative reactions. Furthermore, it may influence cellular signaling pathways related to inflammation and apoptosis, and serves as a building block that can be oxidized and polymerized to form more complex proanthocyanidins, which have enhanced bioactivity.

Leucocyanidin is indicated for use as a high-purity biochemical standard in phytochemical and nutritional analysis. Its primary applications are in research focused on plant biochemistry, antioxidant mechanisms, and the biosynthetic pathways of flavonoids and tannins. It is also studied for its potential application as an antioxidant ingredient in nutraceuticals for combating oxidative stress, in cosmetic formulations for skin protection, and in food science for its role in food quality and stability.

While direct clinical trials on Leucocyanidin are limited, its efficacy is strongly supported by extensive in vitro and ex vivo studies demonstrating superior free radical scavenging and metal chelating activities. Research on its more stable polymeric forms, the proanthocyanidins (e.g., from grape seed, pine bark), shows clinical benefits for vascular health, anti-inflammation, and skin protection, implying the foundational role of monomers like Leucocyanidin. Its potential health benefits are inferred from its strong antioxidant profile and its role as a precursor to clinically studied compounds.
