Support a Sharper Mind. Protect What Matters Most.

Prevagen Extra Strength is the enhanced-dose brain health supplement featuring apoaequorin — a unique protein originally discovered in bioluminescent jellyfish — combined with vitamin D3 to support memory, mental clarity, and healthy brain function. As we age, our brains become increasingly vulnerable to the effects of cellular stress, calcium dysregulation, and the gradual decline in proteins that protect brain cells — processes that contribute to the mild memory lapses, mental fog, and reduced sharpness that many adults begin to notice in their 40s, 50s, and beyond. Prevagen Extra Strength provides 20mg of apoaequorin per capsule — double the dose of the original Prevagen formula — for those who want maximum support for brain health and cognitive function. With 60 capsules delivering a full 2-month supply, Prevagen Extra Strength is the convenient, once-daily brain health supplement trusted by millions of Americans for supporting the memory and mental clarity that make life richer and more connected.

Suggested Use

Take 1 capsule daily in the morning with or without food. Prevagen is designed for once-daily use — do not exceed the recommended dose. For best results, use consistently every day as brain health supplements work cumulatively over time; many users report noticing improvements in memory and clarity after 30–90 days of consistent daily use. Prevagen is generally well-tolerated; however, consult your healthcare provider before use if you are pregnant, nursing, have a known medical condition, or are taking prescription medications. If you are allergic to shellfish or other sea creatures, consult your physician before use. Keep out of reach of children. Store at room temperature away from direct sunlight.

Key Features

• Apoaequorin — Prevagen's Unique Active Ingredient: Apoaequorin is a calcium-binding protein originally isolated from the Aequorea victoria jellyfish, which uses it to produce bioluminescence. In the body, calcium dysregulation in brain cells is a known contributor to neuronal stress and the cognitive changes associated with aging — brain cells gradually lose their ability to regulate calcium levels, which can impair their function and survival. Apoaequorin was studied for its potential to support calcium balance in brain cells and provide a neuroprotective effect, and it is the ingredient that makes Prevagen categorically different from conventional brain vitamins or nootropic supplements
• Extra Strength 20mg Dose: Prevagen Extra Strength delivers 20mg of apoaequorin per capsule — twice the 10mg found in the original Prevagen formula. This higher dose is designed for individuals seeking maximum brain health support, those who have been using the original formula and want to step up their regimen, or those advised by their healthcare provider to use a higher-strength option. The extra strength formula maintains the same safety and tolerability profile established for apoaequorin in human studies
• Vitamin D3 for Brain & Neurological Health: Prevagen Extra Strength includes 50mcg (2,000 IU) of vitamin D3 — the bioactive, preferred form of vitamin D that is most efficiently absorbed and utilized by the body. Vitamin D receptors are expressed throughout the brain, and vitamin D plays documented roles in neuronal function, neuroprotection, mood regulation, and the modulation of neurotransmitter synthesis. Vitamin D deficiency — which is extremely common, particularly in older adults and those with limited sun exposure — has been associated with cognitive decline and increased dementia risk, making D3 a meaningful addition to a brain health formula
• Trusted by Millions: Prevagen is the #1 pharmacist-recommended memory support supplement brand in the United States, with a large and loyal user base built over years of consistent availability and a well-established safety record. Its unique mechanism of action, straightforward once-daily dosing, and widespread availability have made it the go-to brain health supplement for adults concerned about maintaining their memory and cognitive vitality as they age
