Antioxidant herb extract used for memory and preservation
We rank Rosemary Extract by price per gram of active ingredient - not by pack size - so a bigger tub with a worse price per dose can't outrank a smaller one that's actually cheaper.
Rosemary Extract is a concentrated form of the active compounds found in the rosemary plant. It is primarily used as an antioxidant, which is a substance that stops other molecules from breaking down or spoiling.
The process begins by taking the leaves of the rosemary plant and using a solvent, such as alcohol or carbon dioxide, to pull out the beneficial oils and compounds. This liquid is then filtered and evaporated to remove the solvent, leaving behind a concentrated powder or oil that can be put into capsules or mixed into other supplements.
This ingredient is generally affordable. The raw plant material is easy to grow in large quantities and the extraction process is straightforward and common, leading to high supply and plenty of competition between manufacturers.

| cognitive function in adults with chronic obstructive pulmonary disease | 1,000 milligrams daily | emerging |
