## Abstract

Background. SuperUlam is a proprietary blend of natural ingredients aimed at supporting brain health. We aimed to evaluate the effect of SuperUlam on attention and mood in healthy adults. Methods. Twenty healthy individuals aged 35–65 were enrolled in this randomized, double-blind, placebo-controlled, crossover study. Study duration was 3 weeks and consisted of 3 visits. Measurement of cognitive function included computer-based testing of reaction time, complex attention, working memory, sustained attention, and executive functioning. Mood testing was performed via the profile of mood states (POMS) survey and the Chalder fatigue scale. Results. Cognitive function testing demonstrated a significant improvement from baseline in executive functioning, cognitive flexibility, reaction time, and working memory in the product group only (P<0.05). When comparing the study product to placebo, the data demonstrated a significant decrease in tension, depression, and anger (P<0.05). There was no significant difference between the product and placebo in the other measures of mood, including vigor, fatigue, confusion, and total mood disturbance. No adverse events were reported. Conclusions. Supplementation with SuperUlam is safe to consume with potential benefits to cognitive function and mood.

## 1. Introduction

In the past several years, much attention has been paid to products aimed at increasing energy, attention, and concentration. Products such as energy drinks, herbal supplements, and teas are often marketed to healthy individuals who wish to improve their cognitive health. Although popular and readily available, these products are not without risks. While consumption of one serving by a healthy adult may prove no harm, adverse cardiovascular and neurologic effects have been reported [1]. This has led to an increasing interest by consumers for safe products that can acutely increase concentration and memory.Ginkgo bilobais a tree leaf extract commonly used as a memory and concentration enhancement. It has been investigated extensively both in patients with dementia or cerebral insufficiency as well as in healthy adults [2–5]. Plant extracts such as sireh (Piper betle) are used traditionally as stimulants throughout Asia. The spice turmeric (Curcuma longa), commonly found in Asian curries, has been described to have antioxidant and has neuroprotective effects [6]. A recent study demonstrated that consumption of curry-spiced foods was associated with increased Mini-Mental State Examination scores in healthy elderly individuals [6]. Pegaga (Centella asiatica, also known as gotu kola) and curry leaf (Murraya koenigii) have both been shown to have neuroprotective effects in laboratory research [7, 8]. In Ayurvedic medicine, pegaga is known as a rejuvenating herb for nerve and brain cells and is thought to increase intelligence, longevity, and memory [7, 8]. Both vitamin C and vitamin E have been reported to have potential benefits to cognitive function in elderly patients and those suffering from Alzheimer’s disease [9, 10]. Ulam raja (Cosmos caudatus) is an annual plant found in tropical regions and is traditionally used in Malaysian culture for antiaging and vascular health. Extracts from this plant have been found to be high in proanthocyanidins, which are a class of flavanols that have antioxidant properties [11].SuperUlam is a proprietary product containing extracts of sireh (Piper betle), turmeric (Curcuma longa), pegaga (Centella asiatica), curry leaf (Murraya koenigii), selasih (Ocimum basilicum), kesum (Polygonum minus), ulam raja (Cosmos caudatus), and vitamins C and E. We aim to evaluate the effects of this proprietary blend on areas of cognitive function and mood.Cognitive testing is aimed at making quantitative assessments of cognitive capabilities and degree of high-level thinking. The CNS Vital Signs Systems is a computerized neurocognitive test battery comprised of seven tests: verbal memory, visual memory, finger tapping, symbol digit coding, the Stroop test, a test of shifting attention, and the continuous performance test. The results of the CNS Vital Signs System have been shown to be reliable and valid, compared with conventional neuropsychological tests upon which they are based [12].There are a number of approaches toward testing of mood. POMS is a psychological rating scale used to assess transient, distinct mood states [13]. The moods included are tension, depression, anger, vigor, fatigue, confusion, and total mood disturbance. The Chalder fatigue scale is a self-rating measure for both physical and mental symptoms [14]. The scale consists of eight questions relating to physical symptoms and six questions relating to symptoms of mental fatigue. Items are scored in a Likert format, with response options ranging from “better than usual” to “much worse than usual.” Lower scores are preferable.This randomized, double-blind, placebo-controlled crossover study aims to evaluate the effects of SuperUlam on cognitive function and mood in healthy adult subjects.


## 2. Methods

### 2.3. Study Design

This was a randomized, double-blind, placebo-controlled, crossover study. Simple randomization was prepared using a computer program based on the atmospheric noise method, and sequential assignment was used to determine group allocation. Group allocation was placed in individually numbered envelopes to maintain blinding of all individuals and study staff. Study subjects attended three visits, consisting of a screening visit followed by two visits where product is administered. Subjects were screened at visit 1 to determine study eligibility. This included detailed history and physical examination, questionnaires on alcohol use and compliance, POMS testing, and CNSVS testing. Prior to discharge, subjects were provided standardized food to consume prior to the next visit and instructed to fast for 10 hours and sleep between 4.5 and 5.5 hours the night before the next visit. Subjects were also asked to refrain from consuming caffeine 24 hours prior to baseline visit. On visit 2, subjects were randomized to receive a single dose of either the SuperUlam product or placebo. Testing consisted of CNSVS testing, the Chalder fatigue scale, and POMS scoring. After baseline testing was completed, the subject consumed the study product in clinic, and testing was then repeated every hour for five hours. Standardized food was provided during this time. Between visit 2 and visit 3, subjects underwent a seven-day washout period of any related supplements or stimulants. Crossover of study product was performed at visit 3, where subjects who had received placebo at visit 2 would receive product at visit 3, and those who received product at visit 2 would receive placebo at visit 2. Otherwise, previsit preparation and visit procedures were conducted in a manner identical to visit 2. Product was only consumed in clinic and no product was dispensed for home consumption.


### 2.4. Outcome Measures

The primary objective of this study was to assess the effects of the SuperUlam product compared to placebo on the ability to improve attention and memory. Endpoints included cognitive function measurements, which were assessed using the computer-based CNS Vital Signs System (CNSVSS) (Morrisville, NC). The secondary objective of this study was to assess the effects of the SuperUlam product compared to placebo on mood state which were measured by the POMS and the Chalder scales. Table3 outlines the scoring system and definitions for the CNSVSS, POMS, and Chalder scales. The tertiary objective of this study was to evaluate the safety of SuperUlam. Safety endpoints included vital signs (temperature, blood pressure, pulse, and respiratory rate) and adverse event (AE) reporting.Table 3

P < 0.05 versus placebo at this time point.When comparing hour 5 to baseline, subjects receiving active study product demonstrated statistically significant improvement in cognitive flexibility (P=0.048), reaction time (P=0.01), working memory (P<0.01), sustained attention (P=0.048), and executive functioning (P=0.042). Subject in the active group did show an increase in processing speed from baseline to hour 5 (P<0.01), a higher speed meaning that the subject took longer to take the test. The overall composite score or the average standard score across all tests showed a statistically significant improvement from baseline to hour 5 (P<0.001).When comparing hour 5 to baseline, subjects receiving the placebo product demonstrated statistically significant worsening in reaction time (P<0.01) and processing speed (P=0.047). Additionally, a significant worsening in working memory among the placebo group was noted when comparing baseline to hours 1 (P<0.01), 2 (P<0.01), 3 (P<0.01), and 4 (P<0.01). Subjects in the placebo group demonstrated improvement from baseline to hour 5 in sustained attention (P=0.02). There was no statistically significant change in the average standard score between baseline and hour 5 in the placebo group.Of the components of the POMS score at hour 5, when compared to placebo, the active product group demonstrated a significant improvement in depression (P<0.01) and anger (P<0.001). Otherwise, there was no significant difference in any of the other components of POMS scoring between product and placebo at hour 5.When comparing hour 5 to baseline, subjects receiving active study product demonstrated statistically significant improvement in tension (P=0.02), depression (P<0.001), anger (P<0.001), vigor (P<0.001), confusion (P=0.03), and total mood disturbance (P<0.001). Subjects receiving placebo demonstrated significant improvement in anger (P<0.001), vigor (P<0.001), confusion (P<0.001), and total mood disturbance (P<0.001) (Table 6).Table 6

## 4. Discussion

Interest in products aimed at improving cognitive performance and mood is steadily increasing. Younger individuals are interested in products that allow them to both study longer and increase energy for social life. As pharmaceutical agents are often plagued with side effects [15], many individuals are in search of a natural option for improving cognitive functioning and mood. Products containing Ginkgo biloba and natural sources of caffeine such as tea and guarana have been investigated in clinical trials and are readily commercially available [2–5, 16, 17]. Other products, such as energy drinks, may not be well researched, may be costly, may require large amounts, or may contain caffeine or other stimulants.SuperUlam is a proprietary mixture of vitamins C and E as well as extracts from plants shown in laboratory research or traditional use to improve concentration, mood, and/or energy. Extracts of sireh (Piper betle), turmeric (Curcuma longa), pegaga (Centella asiatica), curry leaf (Murraya koenigii), selasih (Ocimum basilicum), kesum (Polygonum minus), and ulam raja (Cosmos caudatus) are included. Although the potential mechanisms of action for cognitive and mood improvements of these agents are not completely clear, there is evidence of neuroprotective effects of turmeric (Curcuma longa) and its constituent curcuminoids [18–21], as well as vitamins C and E (tocotrienols and tocopherols) [22–29] in animal models. Tocotrienols have been shown to reduce tumor necrosis factor-alpha and interleukin-1beta in brain regions of ethanol-treated animals [24]. A recent review described in vitroin cell culture studies that suggest the signal transduction mechanisms that may be involved in the neuroprotective effects of curcumin in turmeric (Curcuma longa) [30].Centella asiaticais used traditionally in Ayurvedic and Chinese medicines as a brain tonic  [7, 31–34]. The neuroprotective effects of Centella asiaticahave been shown in various animal models [31, 32, 35], and the learning and memory-enhancing effects of a Centella asiaticaextract were shown in a labyrinth test [36]. In an animal model, Centella asiaticaalso had antidepressant effects, reducing corticosterone levels and increasing levels of monoamine-related neurotransmitters [37].Murraya koenigii (curry leaf extract) has also been shown to improve memory in animal models, perhaps by reducing cholinesterase activity [8, 38]. Ocimum basilicum has been traditionally used to support neuroprotection. An animal model has shown that extracts of Ocimum basilicum extract can improve memory and also have antioxidant effects [39]. Other constituents of SuperUlam with known antioxidant potential include Polygonum minus (kesum) [40], Cosmos caudatus (ulam raja), traditionally used to improve blood circulation, [11] and vitamins C and E [23, 25, 26, 41].While this the first published human trial demonstrating the safety and efficacy of the proprietary SuperUlam product, evidence from other clinical trials demonstrates the effects of many of the individual ingredients found in SuperUlam. Early clinical evidence suggests improvement in cognitive function associated withCentella asiatica [42]. More recently, an aqueous extract of Centella asiatica standardized to constituent tannic acids, as well as asiaticoside and asiatic acid, improved cognitive performance in healthy men and women [43, 44] and in elderly subjects with mild cognitive impairment [45, 46].In this study, SuperUlam was investigated for its ability to improve concentration and mood in healthy adults aged 35–65 years. Significant improvements were noted in multiple aspects of cognitive function and mood state. Of note, the data did demonstrate a worsening in processing speed in both active and placebo groups. We attribute this to fatigue related to performing the testing itself. This is of interest given that these subjects were all partially sleep deprived and had already experienced hours of testing. A loss of vigor and increased confusion would be expected at this stage. A reduction in confusion at this stage may be related to a higher level of mental clarity. Overall, the results suggest that SuperUlam improved concentration earlier in the study (approximately hours 1-2) and mood later in the study (hours 3–5) in healthy adults.In conclusion, the SuperUlam product appears to have a neurostimulatory and neurocognitive performance enhancement effect, impacting various aspects of cognition and memory at different times between one and five hours after a single dose. The product also appears to induce a state of relaxation as evidenced by reductions in tension, anger, and depression between hour four and five after dosing. The results of this study suggest that this product may be of interest to generally healthy middle-aged adults.We attribute the lack of statistical significance in our study to small sample size. A future higher-powered study is needed to investigate an appropriate number of individuals to generate further statistically significant results. Further animal andin vitrostudies are needed in order to fully determine the mechanism of action. Pharmacokinetic and pharmacodynamic testing may be required to understand the dissolution, absorption, and activity characteristics of this product. There is also need for investigation in older individuals and young adults, as well as in adults using medications or with disorders that may increase the risk of cognitive impairment.
