We explored the connection between vitamin D levels and the frequency of upper respiratory tract infections (URTI) in physically active individuals throughout different seasons. In our research, we observed over 1,600 military recruits during their basic training, noting that only 21% were vitamin D sufficient during winter. Alarmingly, those who had sufficient vitamin D levels were found to be 40% less likely to experience URTIs compared to their deficient counterparts, suggesting that maintaining adequate vitamin D may be crucial for better respiratory health during demanding training periods.
Building on these findings, we conducted a follow-up study with 250 recruits, where we implemented various vitamin D supplementation strategies. Participants received either a placebo, simulated sunlight exposure, or oral vitamin D3 supplementation. The results were promising: vitamin D helped alleviate the severity of URTI symptoms and significantly reduced the number of days experiencing a cold. Notably, both sunlight and dietary supplementation were equally effective in boosting vitamin D levels and improving outcomes.
Overall, achieving vitamin D sufficiency can markedly reduce the burden of URTIs, particularly in physically demanding scenarios such as military training.

I love that these capsules don't contain lanolin. I've been taking one daily for 15 years, and they have reversed my osteopenia and improved my immune system. Most years, I hardly catch the common cold, perhaps only once. They're essential, and Carlson sources these from the wild with no chemical processing.

We explored the effects of vitamin D supplementation in patients with liver cirrhosis—a progressive disease that often manifests alongside vitamin D deficiency. In a carefully designed study, we involved sixty patients who participated in a double-blind, randomized controlled trial. Each patient received either a weekly dose of 50,000 IU of vitamin D or a placebo over 12 weeks.
Throughout the study, we assessed key health markers before and after supplementation, including liver function tests, lipid profiles, and glycaemic indices such as fasting blood glucose and insulin resistance. By the end of the trial, our findings indicated that vitamin D supplementation significantly improved fasting blood glucose levels and insulin resistance in the participants.
Specifically, we observed noteworthy increases in serum 25-hydroxy-vitamin D levels and reductions in fasting blood glucose and insulin resistance indicators. These results suggest that vitamin D might be an important player in improving metabolic health for those suffering from liver cirrhosis.

We observed a fascinating case involving a male in his 40s who experienced persistent inflammatory back pain for three months. Despite having a negative test for HLA-B27, a marker often associated with axial spondyloarthritis, clinical assessments suggested possible underlying issues.
The clinical investigation led to an MRI, which confirmed bilateral symmetrical sacroiliitis. Interestingly, further tests showed he had very low vitamin D levels along with elevated parathyroid hormone—indicating a possible deficiency impacting his condition.
After starting treatment with vitamin D alongside nonsteroidal anti-inflammatory drugs (NSAIDs), he experienced notable relief from his symptoms. His condition improved significantly, and follow-up tests indicated that his vitamin D levels had normalized.
This case demonstrates the potential benefits of vitamin D in managing back pain, especially when classical markers are inconclusive. It highlights how a thorough diagnosis can reveal interconnected health issues and improve treatment outcomes.

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.

Eicosapentaenoic acid reduces MS symptoms
We explored the therapeutic effects of eicosapentaenoic acid (EPA) in tackling multiple sclerosis through a study involving mice with experimental autoimmune encephalomyelitis (EAE). The mice were given diets enriched with or without EPA. Remarkably, the mice that received the EPA-infused diet displayed significantly lower clinical scores compared to those that did not.
Furthermore, we observed that the production of inflammatory markers like IFN-γ and IL-17 was notably reduced in the EPA-treated mice. This reduction is particularly important, as these markers are associated with the progression of multiple sclerosis. Additionally, there was an enhancement in the expression levels of peroxisome proliferator-activated receptors within the CD4T cells infiltrating the central nervous system.
These findings suggest that EPA could serve as a promising new approach to therapy for multiple sclerosis, showcasing its potential in reducing inflammation and improving clinical outcomes in those affected by this condition.

We explored the potential benefits of vitamin D3 supplementation in alleviating knee pain associated with osteoarthritis (OA). In this open-label clinical trial, we assessed the effects of daily doses of 4000 IU vitamin D3 over three months in 80 patients suffering from knee OA.
Our findings revealed notable improvements in pain levels and overall physical function. The patients showed significant reductions in pain scores measured by the Visual Analog Scale (VAS) and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) subscores after the treatment period. Remarkably, 86.7% of those treated responded positively to the therapy.
Interestingly, we observed changes in systemic cytokine levels: while some pro-inflammatory markers increased, others, including TNF-α and IL-17, showed significant reductions. This suggests that vitamin D3 not only helps with pain relief but also may influence inflammatory processes in the body.
Overall, our results indicate that vitamin D3 supplementation could be a promising therapeutic option for managing symptoms of knee OA. Nonetheless, future research should further investigate the role of specific inflammatory mediators, like IL-33, in the progression of knee osteoarthritis.

Cod liver oil aids rheumatoid arthritis
In a recent study involving 43 patients suffering from rheumatoid arthritis, we explored the impact of taking 1 gram of cod liver oil daily for three months. The results were striking. We observed notable reductions in morning stiffness by an impressive 52.4%, alongside decreases in both painful and swollen joints, each showing a 40% improvement. Pain intensity also saw a significant drop of 67.5%.
Additionally, the feedback from the patients was overwhelmingly positive. Approximately 68% reported that the treatment was effective, while a remarkable 95% praised its tolerability. However, it’s worth noting that 11 patients did experience some nonsevere adverse effects, but only three of those were possibly related to the cod liver oil itself.
Overall, it seems that cod liver oil can indeed offer relief for those grappling with rheumatoid arthritis, making it a treatment worth considering for improving symptoms of this autoimmune disorder.

Cod liver oil shows potential benefits
We explored the impact of cod liver oil on cardiovascular health, particularly its influence on heart disease processes. While marine fish consumption offers some benefits, high doses of fish oil can raise certain cholesterol levels and potentially increase risks.
In our study, we observed that when swine were given an atherogenic diet along with cod liver oil, important reductions in harmful monocyte adhesions and platelet clumping occurred. This suggests that fish oil may help improve blood flow and could be less risky than previously thought.
However, while promising, these effects from cod liver oil need more investigation to clarify their relevance in humans.

We investigated how cod liver oil affects coronary artery disease in pigs on a high-fat diet over eight months. By comparing 7 pigs that received cod liver oil to 11 control pigs, we observed significantly less disease in the oil-fed group. Notably, lesion size and arterial narrowing were reduced, suggesting that cod liver oil may influence heart health. Both groups had high lipid levels, but the differences in atherosclerosis weren't linked to these levels. This study hints at the oil's potential to slow coronary disease progression via changes in metabolism.
