Insights & Discussion
Honey contains 20(S)-Hydroxyvitamin D3 (20(OH)D3) and its derivatives, including 20(OH)-7DHC, 25(OH)D3, and 1,25(OH)2D3, indicating their production in bees and suggesting potential health implications.
This study explores the presence of vitamin D3 derivatives in honey, emphasizing the detection of 20(OH)D3 and related compounds. Analysis using LC-MS revealed distinct peaks corresponding to these derivatives, implying their production in bees during the summer in Alabama.
The identification of 20(OH)D3, 20(OH)-7DHC, 25(OH)D3, and 1,25(OH)2D3 in honey suggests their synthesis within bees, highlighting potential biochemistry and photochemistry processes. This finding opens avenues for understanding the health-related implications of these compounds in honey.
We determined the concentration of 20(OH)D3 in honey to be 0.26 µg/g, corresponding to approximately 10 IU/g.
Using an LC-MS assay utilizing 20(OH)D3-d3 as internal standard, we determined the concentration of 20(OH)D3 in honey to be 0.26 µg/g, corresponding to approximately 10 IU/g based on the conversion for vitamin D3 (400 IU = 10 µg). While this may seem relatively low, it must be noted that 20(OH)D3, unlike vitamin D3, is an activated form of the vitamin. It is non-calcemic but exerts many of the other activities of 1,25(OH)2D3 seen in cell culture and in animal studies, with comparable potency. Thus, while the amount of 20(OH)D3 in honey is relatively low, it could potentially be of physiological significance.

Review Article Honey Melatonin Serotonin
The identification of L-DOPA, dopamine, 5-hydroxytryptophan, tryptamine, serotonin, N-acetylserotonin, melatonin, 2-hydroxymelatonin, AFMK, AMK, and vitamin D3 derivatives in honey aligns with their presence in insects and plants. Serotonin and melatonin, integral to tryptophan metabolism, serve diverse roles as hormones, neurotransmitters, and antioxidants. Dopamine and tryptamine, essential neurotransmitters, have broad significance across species. The detection of these molecules in honey, a widely consumed health-promoting substance, enhances its beneficial effects on human health.
The findings highlight the multifaceted composition of honey, encompassing compounds with recognized roles in neurotransmission, antioxidant activity, and hormonal regulation. The presence of these molecules not only broadens honey's spectrum of health benefits for humans but also implies their significance in the intricate physiology of social insects, influencing bee development and colony functions. The co-detection of these compounds with vitamin D3 derivatives further underscores the interconnectedness of honey with insect and plant biology, shedding light on potential synergies that contribute to the diverse positive effects of honey on human health.
