Igennus Pure & Essential, Vegan Vitamin D3, 1-Year Supply, 1000 iu, Natural Plant-Based Algae, Small Tablets for Kids & Adults
Igennus Healthcare Nutrition
Why we love it
Plant-based for sustainable living.
Superior D3 form utilized.
Promotes intensive immune support.
Main Highlights
PLANT-BASED EXTRACT – derived from algae, a naturally rich source of vitamin D3, sustainably farmed in a controlled environment, free from contaminants
ACTIVE D3 FORM – vitamin D3 (cholecalciferol) is the superior form produced in the body, therefore better absorbed and utilised. Until recently, the only vegan-friendly sources offered vitamin D2
INTENSIVE IMMUNE SUPPORT – a daily dose of 1000 iu to ensure healthy levels of vitamin D3 in the body to support the immune system (unlike large doses which upset the ratio of calcium and vitamin D)
SMALL TABLETS & HIGH ABSORPTION – we use tablets rather than oil-based capsules to avoid issues associated with fat malabsorption. Tablets are very small, suitable for both children and adults
SUSTAINABLE & VEGAN – algae is an environmentally friendly source of vitamin D3, GMP manufactured in the UK, 1-year supply
