PQQ is pyrroloquinoline quinone. It is sometimes called methoxatin, pyrroloquinoline quinone disodium salt, and a longevity vitamin. It is a compound made by bacteria and is found in fruits and vegetables.

PQQ in bacteria helps them digest alcohol and sugar, which makes energy. This energy helps them survive and grow. Animals and plants don't use PQQ the same way that bacteria do, but it helps plants and animals grow. It also seems to help them tolerate stress.

Plants absorb PQQ from the bacteria in the soil. They use it to grow, which is then found in fruits and vegetables. It naturally exists in lots of different foods, including:

• Fermented soybeans, or natto
• Green peppers
• Kiwi
• Parsley
• Tea
• Papaya
• Spinach
• Celery

It's also often found in breast milk. This is probably because it is absorbed from the fruits and vegetables consumed and passed into milk.
