Viridian Nutrition’s Vitamin D3 used in clinical trial

D3 successful in preventing Vitamin D deficiency over winter, reveals study. 

Viridian Nutrition’s Head Nutritionist discusses the clinical study involving Viridian’s Vitamin D3. 

A clinical trial has shown individuals who supplemented with Viridian Nutrition’s Vitamin D3 improved their levels of the micronutrient - avoiding vitamin D deficiency during the winter months.

Uncovering the Vitamin D study

The study, by the University of Surrey, involved two parallel randomized controlled trials (RCT) on 135 women split across high and low latitudes. They all had the same ethnic background and each participant had varying levels of vitamin D at baseline.

The individuals received either 15 micrograms or 15µg (600IU) daily or a placebo for 12 weeks.  The results showed that supplementation with Viridian’s Vitamin D supplement daily compared to placebo, significantly raised vitamin D levels, regardless of location and therefore the amount of sunlight.

Interestingly, the research found supplementation had clearly prevented vitamin D deficiency throughout winter, even though 18% were deficient in this group at the beginning.

The study also suggested increasing recommended vitamin D intake to reach optimal levels during the cold season.  Researchers found that optimal blood plasma levels are 75nmol/l which is up to 3 times previous levels. From this, the study recommended that the daily intake for women living in England would be between 15 micrograms or 15μg (600 IU) and 37 micrograms or 37 μg   (up to 1490 IU) to meet the optimal threshold by the end of winter.

Researchers are a leading authority

The published study was conducted by M. Mendes at the University of Surrey alongside Dr. Susan Langham-New who is a Professor in Human Nutrition and is a member of the Scientific Advisory Committee on Nutrition (SACN).

A well-known authority in vitamin D, Dr. Susan Langham-New was part of the SACN Vitamin D Working Group which published the new UK Vitamin D Requirements in 2016.

Reaction from Viridian’s head nutritionist

Viridian Nutrition’s Head Nutritionist Aimee Benbow, said: “This clinical trial confirms that Viridian Nutrition’s Vitamin D3 is effective in improving vitamin D concentrations in the body. The outcome of this study is yet another step forward in vitamin D research.

“We pride ourselves on the fact that our formulations are based on high quality clinical studies, with strict standards on purity, and contain only 100% active ingredients with no unnecessary binders or fillers.

“Picking the right supplements can be difficult as they can vary so it’s important to check the label to ensure it’s a high-quality supplement with 100% active ingredients.”
 
Having sufficient levels of vitamin D in the body is vital

Vitamin D plays an important role in many areas of health. Firstly, vitamin D is essential for keeping bones1 and muscles2 healthy. Vitamin D status has also been closely linked to cardiovascular health3 and has strong associations with cognitive wellbeing4.

Importantly, vitamin D is also involved with supporting the immune system with evidence to suggest that vitamin D may help in prevention of colds and flu viruses5.

Vitamin D deficiency is currently a major global public health issue with increasing prevalence. The main source of vitamin D is through the action of UV from the sun onto our skin.
