Overview
Island Nutrition sells this as a 1 fluid ounce bottle of organic liquid oregano oil drops, certified USDA Organic and grown in Spain. The maker states a 75% carvacrol concentration on the label and markets the product for immune support, framed as a stated claim rather than a medical one.
The label describes the taste as very strong oregano flavor, which tracks with it being sold undiluted rather than pre-mixed into a carrier oil or capsule. It fits several diet labels, including gluten free, keto, plant based, vegan, and vegetarian, which is worth noting for anyone filtering by those needs.
At $38 for a single ounce, it sits at a premium price point per ounce compared to some other liquid drops in this category, though the USDA Organic certification and consistent 4.6 average across 3,200 reviews suggest buyers generally find it worth the cost. As with any supplement, it is worth talking to a healthcare professional before adding it to a routine.

What buyers say

Frequently asked questions
What does the 75% carvacrol figure mean?
Carvacrol is the compound the maker highlights as the main stated component of the oil, and 75% refers to the concentration listed on the label. This is a description of the product's makeup, not a claim about treating or preventing any condition.
Is it suitable for a vegan or keto diet?
Yes, the label lists compatibility with gluten free, keto, plant based, vegan, and vegetarian diets.
How strong does it taste?
The maker describes it as a very strong oregano taste since the oil is undiluted. Many buyers mix it into water or juice to make it easier to take, and it is a good idea to check with a healthcare professional before starting any new supplement.
