What is THORNE Cognitive Vitality, Magtein Magnesium L-Threonate, Capsules?
THORNE Cognitive Vitality, Magtein Magnesium L-Threonate, Capsules is listed as a 90-count capsule supplement from THORNE, with magnesium L-threonate as its primary supplement type. The listing describes Cognitive Vitality as a dietary supplement for cognitive health, not as an assessment or wellness program. Cognitive Vitality is therefore presented in the supplied product information as a supplement.
That positioning differs from Thorne Clear Focus, described as a caffeine-free nootropic formula supporting focus, memory, and mental clarity, and Memoractiv, described by a separate source as a nootropic dietary supplement for everyday mental performance in healthy adults. The sources provided here don’t establish where a Cognitive Vitality page appears on Thorne’s website. Cognitive Vitality’s Amazon listing gives product specifications and claims, but those details don’t establish a separate Thorne webpage or program.
What does Cognitive Vitality claim to do, and what are its key ingredients?
Cognitive Vitality’s Amazon description says magnesium L-threonate helps increase brain magnesium levels and supports neural connections associated with focus, learning, and short- and long-term memory formation. These are listing claims, not independently verified outcomes in the information provided. Cognitive Vitality is also described as supporting brain health, memory, focus, cognitive function, and sleep quality.
The listed serving contains 2,000 mg of Magtein magnesium L-threonate, providing mg of magnesium. The listing identifies magnesium L-threonate as the supplement type and capsules as the product form. Cognitive Vitality’s available sources don’t include independent product-testing results or a summary of buyer reviews. The listing also includes an NSF Certified for Sport specification, but the supplied material doesn’t provide independent test results for this product. Read the benefit language as the listing’s description rather than evidence that you’ll experience those effects.

How do you take Cognitive Vitality, and what serving size is listed?
Cognitive Vitality’s suggested use is three capsules daily or as recommended by a health-care practitioner. The supplement facts list a serving size of three capsules and servings per container. Those are separate label details: the listing states both the daily-use direction and the serving count, without requiring you to infer a different regimen.
The product name and Amazon specification identify a 90-capsule container, while the serving information lists three capsules per serving. Cognitive Vitality’s sources don’t provide an alternative serving schedule or instructions for adjusting the amount. Follow the product’s stated directions, or ask a health-care practitioner if you need individualized guidance. The listing also says use may be as recommended by a health-care practitioner.
How much does Cognitive Vitality cost, and are subscription or bundle options listed?
Cognitive Vitality is listed on Amazon at $69, and its stated list price is $69.00. The Amazon listing information also reports the product as in stock. These are listing details; the supplied sources don’t confirm a bundle offer or an Amazon subscription option.
A Subscribe & Save option is reported for the iHerb listing, not confirmed for Amazon. That distinction matters if you’re comparing ordering routes: an option reported by another retailer shouldn’t be assumed to apply to the Amazon listing. Cognitive Vitality’s available price information gives no additional bundle pricing or subscription discount. The figures provided are $69 and $69.00, with no other Amazon price or offer confirmed in the supplied material.

What safety information should you check before taking Cognitive Vitality or alternatives?
The supplied Cognitive Vitality listing information says to consult a health-care practitioner before use if you’re pregnant. The available sources don’t provide a complete Cognitive Vitality side-effect or medication-interaction list, so they don’t answer every safety question you may have about this supplement.
Clear Focus has different warnings: its page lists contraindication for a history of hypersensitivity to any ingredient and says not to use it if pregnant, nursing, or trying to conceive. It also says tyrosine is contraindicated for people taking an MAO inhibitor antidepressant medication. Memoractiv’s separate source says people who are pregnant or nursing should avoid it; it also reports cautions about blood thinners or upcoming surgery, antidepressants or MAOIs, and thyroid or liver conditions. These are product-specific cautions, not interchangeable instructions. Check with a health-care practitioner about your own circumstances and medications.
How can you order Cognitive Vitality, and what shipping or return information is available?
Cognitive Vitality is listed as in stock on Amazon. The supplied Amazon information doesn’t state shipping estimates, return conditions, or refund details, so those terms are unknown from these sources.
The iHerb listing is a separate retailer’s information: it says free shipping is available for a selected shipping service and advises proceeding to checkout for an accurate delivery estimate. It also states that the product is guaranteed authentic and covered by that retailer’s easy returns and refunds policy. Those iHerb statements don’t establish Amazon’s shipping or return terms. Before ordering, rely on the terms shown for the retailer you choose; the provided information doesn’t confirm that either retailer’s conditions apply to the other.

How does Cognitive Vitality compare with Thorne Clear Focus, Memoractiv, and Brain Factors?
Cognitive Vitality supplies magnesium L-threonate, with a listed serving of three capsules providing 2,000 mg of the ingredient and mg of magnesium. Clear Focus instead lists L-tyrosine and sage extract; each serving contains mg of L-tyrosine and mg of sage extract, and its serving size is two capsules.
Memoractiv’s separate source lists a two-capsule serving with mg of Acetyl-L-Carnitine, mg of Lutein, and mg of Zeaxanthin Isomers. Thorne describes Brain Factors as promoting cognition, learning, and memory, while its product listing describes Memoractiv as supporting productivity, creativity, and mental focus. The available sources don’t provide comparative trial results, so they don’t establish that one product is more effective. Cognitive Vitality, Clear Focus, Memoractiv, and Brain Factors have distinct listed descriptions and ingredients.
Where can you find Thorne’s Cognitive Vitality page?
The available source information doesn’t identify where a Cognitive Vitality page appears on Thorne’s website. The supplied materials include Amazon product specifications and an iHerb dietary-supplement description, but they don’t establish a Thorne page location for this product. Cognitive Vitality’s location on Thorne’s website is therefore unknown from the information provided.
That gap is distinct from Clear Focus, which is described on thorne.com as a caffeine-free nootropic formula supporting focus, memory, and mental clarity. The Clear Focus page information doesn’t verify a page for Cognitive Vitality. If you’re trying to locate product guidance, don’t treat the available Clear Focus page information as confirmation of a Cognitive Vitality webpage.
