Sage is a herb, so the good news is that vegetarians and vegans are able to eat sage.
When it comes to dietary supplements, you should ensure that you check the ingredients to ensure that they are suitable for both vegetarians and vegans.
A Vogel Menoforce Sage Tablets and Vitabiotics Ultra Sage 1000mg Tablets are both suitable for anyone following a vegan or a vegetarian diet as they do not contain any animal products.
