Olive leaf extracts – were you told that your child should take them?

Or maybe you read about it in a Facebook group?

Does it seem kind of mysterious?

Maybe you’ve heard some good things, but then maybe you also heard some bad things. You might be curious, but just not sure about trying it.

Olive leaf extract can impact a lot of health, so let’s get learning. Olive leaf Extract is from the leaf of the Ola Europa tree. It contains a molecule, Ola European, which helps the tree remain healthy by inhibiting fungal growth. There are also many other beneficial molecules within the actual olive leaf extract. Oleuropein is also an antibacterial and has activity against parasites. So that is one specific molecule that’s in the olive leaf extract.

Most people learn that olive leaf extract is potent against Candida. However, it’s so much more than that. As you just saw on the previous slide, candida is only one aspect that Olive Leaf extract is active against.

Think of trees needing to be healthy, out in nature. Would nature make molecules that would only target one thing? No, not at all. Nature is extremely smart. Nature has evolved to be multi-purposeful and the olive leaf extract is going to have more potency than just against Candida.

Why is olive leaf extract used?

Mainly it’s to target dysbiosis (gut dysbiosis). Although many people only associate olive leaf extract with targeting Candida.
