Natrol Cognium: Standalone Cera-Q (Silkworm!) Capsule

Natrol Cognium

Natrol Cognium is a nootropic supplement powered by Cera-Q, a new ingredient derived from silkworm cocoon protein.

Nootropics come in all shapes and sizes. Some are amino acids, others are herbs, and still others are synthetic drugs (like modafinil, discussed in last week’s edition). But you’ve never encountered a nootropic compound quite like today’s product.

Natrol Cognium is a new single-ingredient nootropic that’s derived from silkworms of all things! And unlike many other nootropics on the market, this one actually has a fairly sizeable amount of research backing it as an effective brain boosting and anti-aging supplement.

You may have seen the ingredient before, but if not, get ready to meet Cera-Q.

Cognium Ingredients

Cognium’s lone ingredient is Cera-Q, a trademarked form of silk protein hydrolysate derived from fibroin, the primary protein in silkworm cocoons. Cera-Q is standardized from 60% silk protein hydrolysate, and each serving of Cognium contains 100mg of the brain-boosting protein.

Note: You might also see Cera-Q labeled as BF-7, Brain Factor-7, in several of the research studies. Whatever you want to call it, it’s certainly more appealing sounding than “hydrolyzed silkworm cocoon protein”!

Cera-Q Benefits

As we mentioned up top, Cera-Q has been extensively tested in humans, and so far nine clinical studies have been completed demonstrating significant improvements in memory and cognition after only four weeks of use. But the list of benefits doesn’t end there:

  • Increased Cerebral Blood Flow

    Natrol Cognium Ingredients

    Cognium is pure Cera-Q. If you’ve been intrigued by the ingredient, here’s a way to run it solo.

    Imaging studies done on individuals consuming Cera-Q find that it enhances cerebral blood flow and glucose to certain areas of the brain which are responsible for cognition and memory.[1]

  • Antioxidant Protection

    Cera-Q is also able to defend the body against reactive oxygen species (ROS), which have can increase inflammation and hinder immune system function. Specifically, when subjects were given the protein, ROS were 65% lower in subjects treated with Cera-Q.[2]

  • Neuroprotection

    A 2004 study in Korea enlisted 13 men and 53 women with an average age of 42. Subjects consumed either placebo, 200mg, or 400mg of Cera-Q daily for three weeks.

    Individuals then completed the Digit Symbol Test portion the Korean-Wechsler Adult Intelligence Scale, which is used to measure age, brain damage, depression, dementia. Following the three week trial, the group consuming 200mg and 400mg worth of Cera-Q improved scores by 11.3% and 22.2%, respectively, while the placebo group experienced no improvement over baseline testing.[3]

  • Improved Memory

    Natrol Cognium Pillars

    Cognium supports the 6 pillars of brain health.

    Another Korean study recruited 99 healthy Korean adults and had them consume either placebo, 200mg, or 400mg of Cera-Q daily for three weeks, then perform the Rey-Kim Memory Test, which measure auditory and visual memory.[4]

    As expected the placebo group saw no significant improvements, but the two Cera-Q groups demonstrated significant improvements in memory, measured by word recall in a dose-dependant manner.

    Additionally, subjects also experienced an improvement in memory quotient (MQ), which is “the most direct index reflecting memorizing ability.”[4] And, low memory quotient is also associated with impaired logic and memory recall.[4]

  • Upregulates Acetylcholine production

    The same human study which showed significant improvements in memory, also found that giving Cera-Q to rats was able to increase acetylcholine production[4], which is important in preserving cognitive function as acetylcholine levels tend to decline throughout life.[5]

  • Improves Math Skills

    Cera-Q isn’t just great for memory and word recall, it can also enhance your mathematical abilities too! The Paced Auditory Serial Addition Test (PASAT) measures cognitive function by measuring processing speed and flexibility, as well as calculation ability. A 2009 study had subjects consume 10mg of Cera-Q mixed with 200mL of plain milk and then perform the PASAT.[6]

    According to the researchers:

    “BF-7 milk significantly enhanced the memory, attention, and mathematical abilities of the students. The number of errors made by students taking the Gronwall version of the PASAT was dramatically reduced from an average of 1.46 (before BF-7 milk intake) to 0.42 (after BF-7 milk intake for 30 d)” [6]

  • Better Learning

    As you’d expect, Cera-Q also improves one’s learning ability, which can most likely be attributed to the protein’s ability to enhance acetylcholine production in the body.[4,5,6,9] Acetylcholine is the “learning neurotransmitter” after all!

  • Increased Attention

    Natrol Cognium Name

    No more “senior moments” when using the memory boosting power of Cera-Q.

    Attentiveness is crucial to successful learning, memorization, and basically being productive in everyday life. In other words, if you’re not “with it”, you’re not much use to anyone (including yourself). Cera-Q has been shown across several trials to not only improve learning, memory, and cognition, but also increased attentiveness in both the young and old.[6,7,12]

  • Effective for Children too!

    Cera-Q isn’t just for adults, several trials have investigated its effects on young, healthy children and found that it works there too. In particular, children receiving Cera-Q have demonstrated improved learning, memory, attention, and cognition.[7,8,9]

How the Cera-Q in Cognium is Made

Natrol Cognium Brain Gains

Ready for some serious brain gains courtesy of silkworm cocoon protein.

As you can imagine, extracting silkworm cocoon proteins aren’t the easiest things in the world to do. In order to extract the protein, researchers place the silkworm cocoon in a solution of water and a proprietary mix of enzymes to isolate the fibroin protein. The enzymes then break the fibroin protein strands into shorter peptide chains of amino acids.[11] From there, the resulting mixture is dried to remove the water so all you’re left with is the powdered protein.


Consume 1 tablet in the morning and 1 tablet in evening with a meal.


Who’s ready to start chowing down on some silkworm cocoons?!

Well, maybe you don’t have to go quite that far, but there’s definitely something going on here with Cera-Q, a.k.a. BF-7. Natrol Cognium represents an easy way for those of you intrigued by Cera-Q to get a taste of its effects with no other confounding ingredients like stimulants or other nootropics.
