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.

Fatigue reduction noted
I recommend this concentration of D3 for children. I’ve found that the dosage is essential for combating chronic fatigue syndrome. Higher doses have shown positive effects like increased energy and immune function.

Reduced daytime fatigue
I take this Vitamin D alongside Omega 3, Lycytine, and Magnesium. My chronic fatigue syndrome has improved significantly, as I no longer feel exhausted during the day. The capsules are easy to take, and I sense their quality in my overall wellbeing.

Easier mornings
Following my doctor’s advice for chronic fatigue syndrome, I take vitamin D3 twice daily. After just three weeks, waking up became a breeze, my mood improved, and I felt energised. This vitamin will be a staple for me during the winter months.

Supports calcium metabolism
Annually, I take vitamin D from November to April to support my chronic fatigue syndrome and calcium metabolism. I've noticed significant benefits, including better immune responses and mood improvement.

Eliminated constant fatigue
In my region, vitamin D3 is essential due to lack of sunlight. After my wife and I began taking it, our chronic fatigue syndrome faded, and we feel great now. I trust this brand completely.
