Vitamin D and nausea in gastroparesis
Low Vitamin D Levels in Patients with Symptoms of Gastroparesis: Relationships with Nausea and Vomiting, Gastric Emptying and Gastric Myoelectrical Activity.
Strong link but unclear benefits.
We delved into an intriguing question: how do low vitamin D levels affect nausea in people experiencing gastroparesis, a condition that slows gastric emptying? By measuring the vitamin D levels of patients from the Gastroparesis Clinical Consortium Registry, we aimed to uncover the relationships between vitamin D, nausea, and gastric function.

Our findings revealed that over half of the patients had low vitamin D levels, specifically 56.1% of the 513 individuals studied. We observed a clear association between these low levels of vitamin D and increased experiences of nausea and vomiting. This was particularly notable in patients with delayed gastric emptying, where those with low vitamin D levels reported significantly more nausea.

While the study showed a correlation, it did not address whether supplementing with vitamin D could directly alleviate these symptoms. Instead, we found that lower vitamin D levels also related to a greater retention of food in the stomach after meals, which hints at a connection to gastric neuromuscular dysfunction. Overall, our study emphasized a noteworthy link between vitamin D and nausea but stopped short of confirming any direct treatment benefits.

Vitamin D, genetics, nausea link
Variation in the vitamin D receptor gene, plasma 25-hydroxyvitamin D, and risk of premenstrual symptoms.
Influence of genetics noted
We explored how vitamin D levels affect nausea and other premenstrual symptoms (PMS) while considering the influence of genetics. Our study involved 716 women between the ages of 20 and 29, who provided blood samples to measure their vitamin D status and completed questionnaires about their PMS experiences.

By classifying participants as either vitamin D sufficient or insufficient based on their plasma levels, we examined how these levels correlated with nausea, alongside a specific genetic variation in the vitamin D receptor gene. Interestingly, we found that women with the CC genotype who had low vitamin D levels were more likely to experience nausea, whereas those with the TT genotype exhibited a low likelihood of suffering from nausea under similar conditions.

Overall, we can say that vitamin D's impact on nausea does not occur in isolation; it is modified by genetic factors. This highlights the importance of considering both vitamin D status and genetic background when trying to understand the factors contributing to PMS symptoms like nausea.

No unpleasant feelings
Great value. My lab results indicate low Vitamin D levels. This product is affordable and makes it easy to take the necessary Vitamin D. After taking this, I experienced no unpleasant feelings of nausea or headaches, and I would highly recommend it.

No nausea experienced
Absorbs into the body very well. I prefer gel capsules, but these round tablets outperformed the liquid gel caps I used before. Due to absorption issues, I need to take Vitamin D3 supplements. I won’t name the brand of liquid gel caps, but I will be buying these from now on. I don’t experience any nausea with them and take them alongside other medications at night.
