Vitamin D3 ineffective for CFS
Effect of intermittent vitamin D3 on vascular function and symptoms in chronic fatigue syndrome--a randomised controlled trial.
Directly tests treatment effectiveness
We conducted a thorough investigation into whether high-dose intermittent vitamin D3 could alleviate symptoms of chronic fatigue syndrome (CFS) and improve vascular health. This double-blind, randomized placebo-controlled trial involved patients meeting established criteria for CFS. Participants received either 100,000 units of vitamin D3 or a placebo every two months for six months.
Over the course of the study, we measured key outcomes such as arterial stiffness, blood pressure, cholesterol levels, and fatigue levels through various tests. Surprisingly, our findings showed that vitamin D3 treatment did not lead to any significant improvements in these areas. We observed only a slight increase in vitamin D levels in the treatment group, but this did not translate into better vascular health or reduced fatigue.
In conclusion, we honestly found that high-dose vitamin D3 did not offer any notable benefits for patients struggling with chronic fatigue syndrome. This study highlights the complexities of treating CFS and suggests that vitamin D3 may not be the solution some had hoped for.

Beta-glucan shows cognitive improvements
Yeast Beta-Glucan Supplementation with Multivitamins Attenuates Cognitive Impairments in Individuals with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome: A Randomized, Double-Blind, Placebo-Controlled Trial.
Vitamin D3 effects unclear
We conducted a randomized, double-blind, placebo-controlled trial to explore how yeast beta-glucan, along with multivitamins, affects individuals suffering from Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS). In our study, 65 participants received either beta-glucan combined with vitamins and zinc or a placebo for 36 weeks.
Interestingly, while our primary focus was on beta-glucan, which was shown to significantly improve cognitive fatigue, the role of vitamin D3 within this combination was not clearly established. This makes it challenging to directly assess the impact of vitamin D3 alone on chronic fatigue syndrome outcomes.
Overall, we discovered that beta-glucan supplementation could positively influence cognitive fatigue, offering promise for future research on nutritional support in ME/CFS patients. However, definitive conclusions about vitamin D3's effectiveness remain inconclusive due to the combined nature of the treatment.

Pain and fatigue relief
The Vitamin D helped alleviate my chronic fatigue syndrome. My joints no longer hurt, and I regained energy that had been lacking. I also stopped experiencing frequent headaches, and my nails and hair became stronger. Remarkably, I didn't catch a cold during this period.

Chronic fatigue alleviated
Upon discovering I was deficient, I began taking Vitamin D3, which nearly eliminated my chronic fatigue syndrome. I highly recommend getting tested and ensuring proper vitamin intake.

Gradual symptom relief
After regularly taking Vitamin D, I noted a gradual improvement in chronic fatigue syndrome. My energy levels increased, and I experienced decreased joint pain and improved skin health. It's essential for maintaining bone health in the future.

No fatigue experienced
I initially took a high dosage of Vitamin D for chronic fatigue syndrome, leading to superb benefits. I stopped feeling fatigued and could engage in physical activities joyfully, a marked change from my previous condition.

More energy daily
I've been taking vitamins for three months, and the fatigue I used to experience in the evenings has decreased. I now have enough energy and motivation throughout the day. The price is reasonable, and I recommend this for anyone during the colder months, especially for managing chronic fatigue syndrome.
