'Vegetarian' Vitamin D supplements are sourced from Sheep

Many consumers and prescribers are unaware that cholecalciferol (vitamin D3) commonly found in health supplements and marketed as 'vegetarian' is typically derived from fish oils and from lanolin obtained from sheep's wool. Vitamin D3 is more effective at boosting serum vitamin D levels than the usual plant sources of vitamin D such as ergocalciferol (known as Vitamin D2).

Whether you are on a plant-based diet or looking to live an ethically responsible lifestyle, neither of these two options really offer a solution. Lanolin, far from being a natural pure option, will likely have been contaminated by sheep dip or insecticide at some point.

IMUNI Immune Defence contains a specialised vegan-friendly Vitamin D3 formula which is proudly obtained from lichens - an animal-free, sustainable, eco-friendly, cleaner source.

Fact: lichens comprise a fungus living in a symbiotic relationship with an algae or cyanobacterium (or both).
