Nootropic Supplement Product Development

Development of nootropic supplements as products supporting brain and cognitive health requires a focus on efficacy, quality and purity. Regulatory compliance and safety of ingredients for nootropics are key factors in developing formulas and products.

Facts on Nootropic Supplement Product Development:

  1. NaturPro Scientific assists in the development, sourcing, testing and production of nootropic ingredients and products.
  2. Focus, attention, memory and alertness are all clinical endpoints measured for nootropics.
  3. Nootropics may come in the form of capsules, powders, beverages, tea bags, tablets, liquids and even foods.
  4. Caffeine is one of the most widely consumed nootropics.
  5. Here’s an example of a proprietary Nootropic Tea Formula or NooTea.

What are Nootropics?

From Wikipedia:

Nootropics (pronunciation: /n.əˈtrɒpks/ noh-ə-trop-iks)—also called smart drugs or cognitive enhancers—are drugs, supplements, or other substances that improve cognitive function, particularly executive functions, memory, creativity, or motivation, in healthy individuals.[1][2] The use of cognition-enhancing drugs by healthy individuals in the absence of a medical indication is one of the most debated topics among neuroscientists, psychiatrists, and physicians which spans a number of issues, including the ethics and fairness of their use, concerns over adverse effects, and the diversion of prescription drugs for nonmedical uses, among others.[1][3][4] Nonetheless, the international sales of cognition-enhancing supplements exceeded US$1 billion in 2015 and the global demand for these compounds is still growing rapidly.[5]

The word nootropic was coined in 1972 by a Romanian psychologist and chemist, Corneliu E. Giurgea,[6][7] from the Greek words νους (nous), or “mind”, and τρέπειν (trepein), meaning to bend or turn.[8]

Nootropic Safety and Side Effects

Many ingredients used in nootropic supplements are synthetic substances not found in nature or our food supply. These may be considered unapproved drugs. Central nervous system stimulants and plant alkaloids are also areas of concern for safety, due to their impact on the brain. Many CNS stimulants are considered toxic to the liver and other organs. It is essential that nootropic ingredients are supported by safety studies and a long history of human use, in addition to GRAS (generally recognized as safe) or other suitable safety assessments as determined by regulations.

From Wikipedia: “The main concern with pharmaceutical drugs is adverse effects, and these concerns apply to cognitive-enhancing drugs as well. Long-term safety data is typically unavailable for some types of nootropics[9] (e.g., many non-pharmaceutical cognitive enhancers, newly developed pharmaceuticals and pharmaceuticals with short-term therapeutic use). Racetams—piracetam and other compounds that are structurally related to piracetam—have few serious adverse effects and low toxicity, but there is little evidence that they enhance cognition in individuals without cognitive impairments.[22][23] While addiction to stimulants is sometimes identified as a cause for concern,[24] a very large body of research on the therapeutic use of the “more addictive” psychostimulants indicate that addiction is fairly rare in therapeutic doses.[25][26][27] On their safety profile, a systematic review from June 2015 asserted, “evidence indicates that at low, clinically relevant doses, psychostimulants are devoid of the behavioral and neurochemical actions that define this class of drugs and instead act largely as cognitive enhancers.”[28]

In the United States dietary supplements may be marketed if the manufacturer can show that it can manufacture the supplement safely, that the supplement is indeed generally recognized as safe, and if the manufacturer does not make any claims about the supplement’s use to treat or prevent any disease or condition; supplements that contain drugs or for which treatment or prevention claims are made are illegal under US law.”

Types of Nootropics (From Wikipedia):

Stimulants

Miscellaneous

  • l-Theanine – A 2014 systematic review and meta-analysis found that concurrent caffeine and l-theanine use has synergistic psychoactive effects that promote alertness, attention, and task switching;[43] these effects are most pronounced during the first hour post-dose.[43]
  • Tolcapone – a systematic review noted that it improves verbal episodic memory and episodic memory encoding.[44]
  • Levodopa – a systematic review noted that it improves verbal episodic memory and episodic memory encoding.[44]
  • Atomoxetine – can improve working memory and aspects of attention when used at an optimal dose.[33]

Dietary supplements

  • Bacopa monnieri – A herb sold as a dietary supplement. There is some preliminary evidence for memory-enhancing effects.[45]
  • Panax ginseng – A review by the Cochrane Collaboration concluded that “there is a lack of convincing evidence to show a cognitive enhancing effect of Panax ginseng in healthy participants and no high quality evidence about its efficacy in patients with dementia.”[46] According to the National Center for Complementary and Integrative Health “Although Asian ginseng has been widely studied for a variety of uses, research results to date do not conclusively support health claims associated with the herb.”[47] According to a review published in the journal “Advances in Nutrition”, multiple RCTs in healthy volunteers have indicated increases in accuracy of memory, speed in performing attention tasks and improvement in performing difficult mental arithmetic tasks, as well as reduction in fatigue and improvement in mood.[48]
  • Ginkgo biloba – An extract of Ginkgo biloba leaf (GBE) is marketed in dietary supplement form with claims it can enhance cognitive function in people without known cognitive problems. Studies have failed to find such effects on memory or attention in healthy people.[49][50]

Racetams

Racetams, such as piracetam, oxiracetam, and aniracetam, are structurally similar compounds, which are often marketed as cognitive enhancers and sold over-the-counter. Racetams are often referred to as nootropics, but this property of the drug class is not well established.[51] The racetams have poorly understood mechanisms of action; however, piracetam and aniracetam are known to act as positive allosteric modulators of AMPA receptors and appear to modulate cholinergic systems.[52]

According to the US Food and Drug Administration, “Piracetam is not a vitamin, mineral, amino acid, herb or other botanical, or dietary substance for use by man to supplement the diet by increasing the total dietary intake. Further, piracetam is not a concentrate, metabolite, constituent, extract or combination of any such dietary ingredient. […] Accordingly, these products are drugs, under section 201(g)(1)(C) of the Act, 21 U.S.C. § 321(g)(1)(C), because they are not foods and they are intended to affect the structure or any function of the body. Moreover, these products are new drugs as defined by section 201(p) of the Act, 21 U.S.C. § 321(p), because they are not generally recognized as safe and effective for use under the conditions prescribed, recommended, or suggested in their labeling.”[53]

Null findings in systematic reviews

  • Omega-3 fatty acids: DHA and EPA – two Cochrane Collaboration reviews on the use of supplemental omega-3 fatty acids for ADHD and learning disorders conclude that there is limited evidence of treatment benefits for either disorder.[54][55] Two other systematic reviews noted no cognition-enhancing effects in the general population or middle-aged and older adults.[56][57]
  • B vitamins – no cognition-enhancing effects in middle-aged and older adults.[57]
  • Vitamin E – no cognition-enhancing effects in middle-aged and older adults.[57]
  • Pramipexole – no significant cognition-enhancing effects in healthy individuals.[44]
  • Guanfacine – no significant cognition-enhancing effects in healthy individuals.[44]
  • Clonidine – no significant cognition-enhancing effects in healthy individuals.[44]
  • Ampakines – no significant cognition-enhancing effects in healthy individuals.[44]
  • Fexofenadine – no significant cognition-enhancing effects in healthy individuals.[44]
  • Salvia officinalis – Although some evidence is suggestive of cognition benefits, the study quality is so poor that no conclusions can be drawn from it.[58]
