Apoaequorin

What other names is Apoaequorin known by?

Apoaecuorina, Bioluminescence, Prevagen, Protéine-Liant-le Calcium.

What is Apoaequorin?

Apoaequorin is a protein that was obtained in 1962 from a specific type of jellyfish that glows. When apoaequorin is exposed to calcium, the protein and calcium bind and a blue light is produced. For more than 40 years, apoaequorin has been used to study how calcium works inside cells. Recently apoaequorin has been manufactured on a larger scale for use in the dietary supplement Prevagen.

People take apoaequorin by mouth to improve mental function, memory, and sleep quality.

Insufficient Evidence to Rate Effectiveness for...

  • Amyotrophic lateral sclerosis (ALS, Lou Gehrig’s disease). Some reports suggest that taking 20 mg of apoaequorin every 2-3 waking hours and an additional 20-40 mg 30-60 minutes before bed along with other drugs and supplements might slow the progression of ALS. The effects of taking apoaequorin alone are not clear.
  • Mental function. Early research shows that taking 10 mg of apoaequorin (Prevagen, Quincy Bioscience) daily for 90 days might improve some measures of mental function in older adults.
  • Memory. Early research shows that taking 10 mg of apoaequorin (Prevagen, Quincy Bioscience) daily for 90 days might improve forgetfulness, word recall, and the need for reminders in some people. But, this research is of lower quality.
  • Sleep quality. Early research shows that taking 10 mg of apoaequorin (Prevagen, Quincy Bioscience) daily for 90 days might increase sleep time by around 30-40 minutes per night, cut nighttime awakenings by 50%, and improve sleep quality in over 90% of people with trouble sleeping. But, this research is of lower quality.
  • Other conditions.
More evidence is needed to rate the effectiveness of apoaequorin for these uses.

How does Apoaequorin work?

Apoaequorin is a protein that was originally discovered in the jellyfish species Aequorea victoria. When apoaequorin binds with calcium, a blue light is produced.

Problems with calcium regulation in the human brain are thought to play a role in age-related mental decline. Because apoaequorin has a similar structure to human calcium-binding proteins, some researchers believe it might help regulate calcium in the brain and reduce memory loss and mental decline.

Are there safety concerns?

Apoaequorin is POSSIBLY SAFE when taken by mouth appropriately. A 10 mg dose of a specific apoaequorin product (Prevagen, Quincy Bioscience) has been used safely for up to 90 days. No clinical research has adequately evaluated side effects caused by apoaequorin. Some people who have taken apoaequorin have reported potential side effects to a manufacturer of the product. Some of the most commonly reported side effects were headache, dizziness, and nausea. Others less common events were memory problems, difficulty sleeping, and anxiety. There have also been a smaller number of reports of more serious potential side effects such as heart and nervous system-related events. It is important to understand that although these events occurred while people took this product, this does not necessarily mean that the product caused these events. There is not enough information about these potential side effects to know if apoaequorin was the actual cause of these side effects.

Special Precautions & Warnings:

Pregnancy and breast-feeding: There is not enough reliable information about the safety of taking apoaequorin if you are pregnant or breast feeding. Stay on the safe side and avoid use.

Dosing considerations for Apoaequorin.

The appropriate dose of apoaequorin depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for apoaequorin (in children/in adults). Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.

Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, and Insufficient Evidence to Rate (detailed description of each of the ratings).
