Overview of Prevagen Regular

Prevagen Regular
Prevagen Regular

Prevagen Regular contains 10mg of apoaequorin per capsule. The recommended serving is one capsule per day, providing 10mg of the key active ingredient.

Prevagen Regular is designed for people experiencing normal age-related memory changes like occasional forgetfulness or difficulty with word recall. The lower 10mg dose delivers cognitive support while remaining extremely safe and well-tolerated.

According to the manufacturer Quincy Bioscience, Prevagen Regular promotes sharper mind, clearer thinking, and better recall. It is said to improve proteins that decline with age related to memory and cognition.

The benefits of Prevagen Regular build up gradually over time. Many users report noticeable improvements in as little as 30 days, but full effects are achieved after 90 days of consistent use.

Prevagen Regular is safe for long-term daily use. It does not require a prescription and has no known drug interactions. The 10mg apoaequorin dose has undergone extensive safety testing with no major side effects. Some people report mild digestive upset.

Overview of Prevagen Extra Strength

Prevagen Extra Strength contains 20mg of apoaequorin per capsule, twice the amount in the regular formula. It is designed for more significant memory and cognitive issues related to aging.

The higher 20mg apoaequorin dose provides greater support for memory, focus, learning, and overall mental performance. It delivers benefits faster, with users experiencing improvements within 30 days.

Prevagen Extra Strength helps with moderate to severe age-related memory lapses. It is most effective for people struggling with recall, learning new information, concentrating, or handling complex tasks.

While Prevagen Extra Strength works more rapidly and powerfully, it may also have more side effects than the regular version, especially when initial use begins. Taking with food can minimize digestive upset.

Just like the regular version, Prevagen Extra Strength does not require a prescription. But some people are advised to consult a doctor before use if they have underlying health conditions or take medications.
