Viridian Nutrition has added Vitamin D3 4000IU to its range, making it the highest potency product in its 9-strong vitamin D range 

Vitamin Vitamin D3 has been clinically studied at the University of Surrey and shown to increase blood serum levels of vitamin D. 

Aimee Benbow, nutrition director at Viridian, said: “We are continually reviewing our NPD programme, and in the case of vitamin D, we know there isn’t a one size fits all.

Everyone has different intake requirements, which could be due to addressing deficiencies, and preferences for specific formats whether it’s capsules, liquid or sprays.

“People are also seeking a more convenient way of adding vitamin D to their regimen. The new Viridian Vitamin D3 4000IU is ideal to take 1 – 3 times per week.

“Whereas most vitamin D3 supplements on the market are derived from the lanolin in sheep’s wool, Viridian Vitamin D3 provides vitamin D3 in a vegan form derived from lichen.”
