Three Kasivit products sold together: Brain & Focus Formula, Focus Fuel Mushroom Coffee and CoQ10.
These are three separate products that are also sold individually. The combination has not been studied, and none of the products is a treatment for memory loss, tiredness or any other condition. The coffee contains caffeine and the Brain & Focus Formula contains green tea extract, so count the total from all sources.
Kasivit Brain & Focus Formula — per the confirmed label, a 2-capsule serving provides a multivitamin and mineral base plus a 609 mg proprietary blend that includes Bacopa monnieri extract, green tea extract, phosphatidylserine, huperzine A, DMAE bitartrate, GABA and DHA; the amount of each blend ingredient is not stated. It contains soy and fish (tuna). In trials, Bacopa extract on its own showed modest effects on memory tests: a systematic review of six randomized trials in adults without dementia (12 weeks, 300 to 450 mg of extract a day) found better memory free recall on 9 of 17 tests and little evidence of effects on other thinking skills (Pase 2012). Huperzine A and phosphatidylserine have been studied mainly in older adults with memory problems. No study of this formula is cited.*
Focus Fuel Mushroom Coffee (Medium Roast) — per the label, 90% roasted Arabica coffee, 5% organic Lion's Mane powder and 5% organic Chaga mushroom powder, with a serving of 1 tablespoon (10 g). It contains caffeine; the caffeine amount is not stated. A 16-week trial in 30 adults aged 50 to 80 with mild cognitive impairment found higher cognitive scale scores with 3 g a day of Lion's Mane powder than with placebo, and the scores fell after the powder was stopped (Mori 2009). A 10 g serving of this coffee contains about 0.5 g of Lion's Mane powder, and no study of mushroom coffee is cited. Chaga is high in oxalate, and a case report describes kidney injury after daily use of chaga powder (Kikuchi 2014).*
Kasivit CoQ10 — coenzyme Q10 as ubiquinone in a vegetable capsule. Studies of CoQ10 supplements have given mixed results: meta-analyses of randomized trials found no significant benefit for muscle pain in people taking statins (Banach 2015; Kennedy 2020), while the Q-SYMBIO trial in 420 people with moderate to severe heart failure reported fewer major cardiovascular events with CoQ10 added to standard care (Mortensen 2014). The heart-failure result applies to people with heart failure and not to other people. No study of this product is cited. If you take a statin or warfarin, ask your prescriber or pharmacist before use, and do not stop or change a statin because of a supplement.*
Bundle price of $89.99 vs. $99.48 when the three products are bought separately.
