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.
Most Relevant Research
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 aids rheumatoid arthritis
The role of vitamins D, B12, C, and K in modulating inflammation and disease management in rheumatoid arthritis: a comprehensive review.
Most Relevant Research
We explored how vitamin D plays a role in managing rheumatoid arthritis (RA), a condition that causes joint inflammation and discomfort. It's been found that many people with RA often suffer from vitamin D deficiency, which may worsen their symptoms and overall disease severity.

Our review indicates that vitamin D could help modulate immune responses and lower inflammation levels. Supplementing with vitamin D has shown potential in improving various disease activity markers, signaling that it could be a valuable addition to treatment strategies for RA.

Besides vitamin D, we also looked at other important vitamins like B12, C, and K. While vitamin D stands out for its immune benefits, B12 supports energy and neurological health, C helps with collagen production and inflammation reduction, and K contributes to bone health.

Together, these vitamins create a comprehensive approach to managing RA, emphasizing the need for further research to determine the best ways to use them effectively.

Reduces chronic pain
Most Useful Review
Inexpensive and helpful for body pain. As someone fair-skinned, I struggle with Vitamin D deficiency which has been confirmed by rheumatologists who diagnosed me with fibromyalgia and osteoarthritis. They recommended Vitamin D3, which assists with my fibromyalgia symptoms. When I'm low on this supplement, I notice a significant decrease in pain. Though I dislike the inclusion of maltodextrin, the reduction in my chronic pain is enough to continue using it.

Vitamin D reduces cold severity
Influence of Vitamin D Supplementation by Simulated Sunlight or Oral D3 on Respiratory Infection during Military Training.
Most Relevant Research
We explored the connection between vitamin D levels and upper respiratory tract infections (URTIs) among military recruits during their training. This observation spanned across different seasons and included over 1,600 recruits. Our aim was to understand how achieving sufficient vitamin D levels could potentially impact the frequency and severity of colds among physically active individuals.

In an additional phase of the research, we conducted a randomized controlled trial with 250 male recruits. They received either a placebo, simulated sunlight exposure, or oral vitamin D3 supplements during winter. This comparison allowed us to see if these methods effectively increased vitamin D levels to a sufficient status of 25(OH)D at 50 nmol/L or higher.

Notably, our findings showed that only 21% of recruits had adequate vitamin D during winter, yet those who did were 40% less likely to suffer from URTIs. Furthermore, both vitamin D supplementation strategies similarly helped nearly all participants achieve sufficient levels. Vitamin D supplementation notably reduced the severity of URTI symptoms by 15% and the number of days with URTIs by 36% compared to placebo.

While the supplementation strategies did not significantly alter other immune factors, such as salivary secretory immunoglobulin A, the overall reduction in respiratory infections indicates a beneficial effect of maintaining vitamin D sufficiency during military training.

No colds experienced
Most Useful Review
This is my child's favourite D3 variant: strawberry flavour in a small, easy-to-chew tablet. I've purchased it multiple times and will continue to do so. When taken daily through fall, winter and spring, in addition to multivitamins, it yields excellent results - I can't recall the last time my child had a cold.

Vitamin D3 correction improves pain
Role of Pre-operative Correction of Vitamin D3 Deficiency in Controlling Post-operative Bone Pain after Unicompartmental Knee Arthroplasty.
Most Relevant Research
We explored the impact of vitamin D3 levels on bone pain that patients experience after undergoing unicompartmental knee arthroplasty (UKA). The study involved 240 participants who were divided into three groups based on their vitamin D status—some received treatment before surgery, some after, and others had normal levels to begin with.

By administering vitamin D3 in three doses, we aimed to see if correcting deficiencies could alleviate post-operative bone pain. Throughout the recovery period, we measured pain levels using the visual analog scale at various intervals after the surgery.

Our findings clearly demonstrated that patients who corrected their vitamin D3 deficiency before surgery reported significantly better pain control after the operation compared to those who were treated afterwards or those who started with adequate levels. This highlights the importance of testing and addressing vitamin D status prior to orthopedic procedures, showing that it is a modifiable risk factor affecting recovery.

Pain relief noted
Most Useful Review
Chic vitamin D. It has a delightful taste and excellent dosage. After two weeks, my child's Vitamin D level increased to 9 units, the bone pain in his legs disappeared, and he no longer complaints of fatigue or headache. This is a commendable result. We'll continue the course, have tests, and update the review. Vitamin D is crucial for calcium integration into bones, making it essential for our health. If you found this review helpful, please give it a thumbs up and stay healthy!
