How and Why It Works?

The dietary supplement is designed to greatly support the overall vitality and health of men over 30 years*. The right combination of plant extracts rich in concentrated active substances assists the recovery processes in the body after systematic physical exhaustion and stress.*

The plant Tribulus terrestris growing in Bulgaria is wealthy in furostanol saponins which are present in the dietary supplement as a specific mixture of protodioscin, methyl protodioscin, protogracilin, prototribestin and methylprototribestin.[1, 2] They positively influence the secretion of hormones, support the production of luteinizing hormone and the secretion of hormone testosterone, and assist the regulation of male hormonal balance. *[3, 4]

Able Male® supports the overall physiological condition of the body and helps to keep the healthy levels of testosterone in a natural way for a long period of time. *[3, 4] Consequently, there is no need for use of external sources of testosterone. The Bulgarian Tribulus terrestris extract is a wonderful natural ingredient that supports many aspects of men’s life – muscles, sexual desire, endurance, alertness. *[2, 5]

Mucuna pruriens extract contains the active substance phenylalanine hydroxy-l (L-DOPA), and its action is connected to supporting mood and desire to live actively. *[6] L-DOPA is a precursor of dopamine, meaning that its supplementation positively influences the increase of dopamine levels in the body. *[7] It is known that dopamine benefits memory, attention, movement, pleasure, learning, sleep, etc. It also positively influences the energy levels, stamina, vitality and accelerates the recovery processes in the body. *[8, 9]

The ginkgo flavone glycosides from the Gingko biloba extract are a mixture of biologically active substances: quercetin, kaempferol and isorhamnetin. This extract is applied to support man’s ability to concentrate and reduce fatigue. *[10] It positively influences the psycho vegetative conditions, such as fatigue and insomnia. * What is achieved is a more relaxed, balanced and centered man. *[11]

The dry extract from the roots of Geranium sanguineum contains a complex of biologically active polyphenols and anthocyanins, which are strong antioxidants. *[12] The physiological activity of polyphenolic compounds and the synergy between the different phenolic groups are prerequisites for the desired effect of Able Male®. *[13] Geranium extract is used alone or in combination with other plant extracts to assist the health of the immune system. *[14]

Able Male® has a positive effect on the physical condition of the male body, providing better health status and comfort for the individual. *

3. Milanov, S., E. Maleeva, M. Tashkov. – Tribestan effect on the concentration of some hormones in the serum of healthy subjects (1981)

Tribestan effect has been studied on the serum concentration of hypophyseal hormones, of ACTH, STH, LH, FSH, adrenal hormone aldosterone and cortisol and sex hormones – testosterone and estradiol. The experiments have been carried out on 8 males and 8 females, aged 28 – 45 years of age. The product was perorally administered in a single dose of 250 mg, three times daily for 5 days. Serum samples were withdrawn at 8 a.m. and 12 a.m., prior to and post treatment. The product has been established not to change essentially the concentrations of adrenal hormones and of ACTH. The hypophyseal-gonadal axis however has significantly been affected in the females with predominantly increased concentration of FSH and estradiol and in the males – mainly of LH and the testosterone. The mechanism of that action is presumed to be complicated and realized both by direct effect on gonadal apparatus and by the tropic hormones. The probable established changes in the concentration of the hormones studied do not get out of the frames of the physiological limits. The lyophilized extract of Tribulus terrestris, introduced in veterinary practice as TB-68, has pronounced sex-stimulating function. The initial studies of this product showed that it stimulates the spermatogenesis of albino rats (Vankov S., et al., 1973) and enhanced the ovulation of female rats (Vankov S. et al. 1973). Zarkova S. (1976) has also established in rats an increased number of spermatogonia, spermatocytes as well as increase of neutral mucopolysaccharides in seminiferous tubules of the testes. Gendzhev Z. and S. Zarkova, in other experiments (1978) proved the increase of spermatic reserve in the epididymis of rats. With the view to the need of human medicine of a product stimulating sexual function, Tribestan was formulated on the base of the indicated phytochemical product. It contains saponins of furostanol type (Tomova M. et al., 1978). The first studies of Tribestan confirmed its high sex-stimulating activity in experimental animals (Zarkova S., 1981). Later, the clinical studies established a similar stimulating effect in humans as well (Protich M. at al. 1981). The present study was carried out with a view to throwing light on some aspects of the mechanism of that action of Tribestan, aiming at attaining an effect from the product on the serum concentration of some hypophyseal, sexual and adrenal hormones.

4. Gauthaman, K. and Ganesan, A. – The hormonal effects of Tribulus terrestris and its role in the management of male erectile dysfunction – an evaluation using primates, rabbit and rat Phytomedicine (2008) 15: 44.

Hormonal effects of Tribulus terrestris (TT) were evaluated in primates, rabbit and rat to identify its usefulness in the management of erectile dysfunction (ED). TT extract was administered intravenously, as a bolus dose of 7.5, 15 and 30 mg/kg, in primates for acute study. Rabbits and normal rats were treated with 2.5, 5 and 10 mg/kg of TT extract orally for 8 weeks, for chronic study. In addition, castrated rats were treated either with testosterone cypionate (10 mg/kg, subcutaneously; biweekly for 8 weeks) or TT orally (5 mg/kg daily for 8 weeks). Blood samples were analyzed for testosterone (T), dihydrotestosterone (DHT) and dehydroepiandrosterone sulphate (DHEAS) levels using radioimmunoassay. In primates, the increases in T (52%), DHT (31%) and DHEAS (29%) at 7.5mg/kg were statistically significant. In rabbits, both T and DHT were increased compared to control, however, only the increases in DHT (by 30% and 32% at 5 and 10 mg/kg) were statistically significant. In castrated rats, increases in T levels by 51% and 25% were observed with T and TT extract respectively that were statistically significant. TT increases some of the sex hormones, possibly due to the presence of protodioscin in the extract. TT may be useful in mild to moderate cases of ED.

Mucuna pruriens (Fabaceae) is an established herbal drug used for the management of male infertility, nervous disorders, and also as an aphrodisiac. It has been shown that its seeds are potentially of substantial medicinal importance. The ancient Indian medical system, Ayurveda, traditionally used M. pruriens, even to treat such things as Parkinson’s disease. M. pruriens has been shown to have anti-parkinson and neuroprotective effects, which may be related to its anti-oxidant activity. In addition, anti-oxidant activity of M. pruriens has been also demonstrated in vitro by its ability to scavenge DPPH radicals and reactive oxygen species. In this review the medicinal properties of M. pruriens are summarized, taking in consideration the studies that have used the seeds extracts and the leaves extracts.

8. Kurniawan, I. (2011). Dopamine and effort-based decision making. Frontiers in Neuroscience, 5.

Cognitive control is subjectively costly, suggesting that engagement is modulated in relationship to incentive state. Dopamine appears to play key roles. In particular, dopamine may mediate cognitive effort by two broad classes of functions: 1) modulating the functional parameters of working memory circuits subserving effortful cognition, and 2) mediating value-learning and decision-making about effortful cognitive action. Here we tie together these two lines of research, proposing how dopamine serves “double duty”, translating incentive information into cognitive motivation.

9. Westbrook, A. and Braver, T. (2016). Dopamine Does Double Duty in Motivating Cognitive Effort. Neuron, 91(3), p.708.

Motivational theories of choice focus on the influence of goal values and strength of reinforcement to explain behavior. By contrast relatively little is known concerning how the cost of an action, such as effort expended, contributes to a decision to act. Effort-based decision making addresses how we make an action choice based on an integration of action and goal values. Here we review behavioral and neurobiological data regarding the representation of effort as action cost, and how this impacts on decision making. Although organisms expend effort to obtain a desired reward there is a striking sensitivity to the amount of effort required, such that the net preference for an action decreases as effort cost increases. We discuss the contribution of the neurotransmitter dopamine (DA) toward overcoming response costs and in enhancing an animal’s motivation toward effortful actions. We also consider the contribution of brain structures, including the basal ganglia and anterior cingulate cortex, in the internal generation of action involving a translation of reward expectation into effortful action.

10. Kennedy, Scholey, Wesnes - Modulation of cognition and mood following administration of single doses of Ginkgo biloba, ginseng, and a ginkgo/ginseng combination to healthy young adults.

It has previously been demonstrated in separate studies that single doses of Ginkgo biloba, Panax ginseng, and a combination of the two extracts can improve different aspects of cognitive performance in healthy young volunteers. The present study directly compared the effects of single doses of G. biloba, ginseng, and a product combining the two on aspects of mood and cognitive performance in the same cohort of healthy, young adult volunteers. The study followed a randomised placebo-controlled, double-blind, balanced, cross-over design. Twenty participants received 360 mg of ginkgo, 400 mg of ginseng, 960 mg of a product combining the two extracts, and a matching placebo. Treatment order was dictated by random allocation to a Latin square, with a 7-day wash-out period between treatments. Cognitive testing comprised completion of the Cognitive Drug Research (CDR) computerised assessment battery and two serial subtraction mental arithmetic tasks. Mood was assessed with Bond-Lader visual analogue scales. Following a baseline cognitive assessment, further test sessions took place 1, 2.5, 4, and 6 h after the day’s treatment was taken. The results largely supported previous findings. All three treatments were associated with improved secondary memory performance on the CDR battery, with the ginseng condition evincing some improvement in the speed of performing memory tasks and in the accuracy of attentional tasks. Following ginkgo and the ginkgo/ginseng combination performance of both the Serial Threes and Serial Sevens, subtraction tasks was also improved at the later testing sessions. No modulation of the speed of performing attention tasks was evident. Improvements in self-rated mood was also found following ginkgo and to a lesser extent the combination product.

11. Hemmeter, Annen, Bischof, Brüderlin, Hatzinger, Rose, Holsboer-Trachsler. - Polysomnographic effects of adjuvant ginkgo biloba therapy in patients with major depression medicated with trimipramine.

Sleep disturbance and cognitive impairment are frequent complaints of depressed patients under standard antidepressant medication. Therefore, additional therapies are required which specifically focus on the improvement of these deficits without exerting major side effects. Ginkgo biloba extract (EGb) has been shown to improve cognitive abilities in elderly subjects and in patients with disorders of the dementia spectrum. Animal studies surmise that EGb may reduce CRH activity, which is substantially related to depressive mood and behavior, predominantly cognition and sleep. An open non-randomized pilot study has been conducted to investigate the effects of ginkgo biloba extract (EGb Li 1370) on cognitive performance and sleep regulation in depressed inpatients. 16 patients were treated with a trimipramine (T)-monotherapy (200 mg) for six weeks. In eight of the 16 patients, an adjunct EGb therapy (240 mg/d) was applied for four weeks after a baseline week, the other eight patients remained on trimipramine monotherapy (200 mg) during the entire study. Polysomnography, cognitive psychomotor performance and psychopathology were assessed at baseline, after short-term and long-term adjunct EGb treatment, and after one week of ginkgo discontinuation (at the respective evaluation times in the eight patients on T-monotherapy). This report focuses on the results of EGb on sleep EEG pattern. EGb significantly improved sleep pattern by an increase of sleep efficiency and a reduction of awakenings. In addition, sleep stage 1 and REM-density were reduced, while stage 2 was increased. Non-REM sleep, predominantly slow wave sleep in the first sleep cycle, was significantly enhanced compared to trimipramine monotherapy. Discontinuation of EGb reversed most of these effects. Based on the animal data, these results suggest that EGb may improve sleep continuity and enhance Non-REM sleep due to a weakening of tonic CRH-activity. The compensation of the deficient Non-REM component in depression by the EGb application may provide a new additional treatment strategy, especially in the treatment of the depressive syndrome with sleep disturbance.

12. Murzakhmetova M, Moldakarimov S, Tancheva L, Abarova S, Serkedjieva J.- Antioxidant and prooxidant properties of a polyphenol-rich extract from Geranium sanguineum L. in vitro and in vivo.

A polyphenol-rich extract from Geranium sanguineum L. (PC) protected biological membranes due to its antioxidant capacity. PC caused a dose-dependent decrease of the osmotic hemolysis of human erythrocytes and increased their resistance against the toxic effect of H(2)O(2); no effect on catalase activity was observed. While PC reduced the accumulation of TBA-reactive products in rat liver microsomes in inducible lipid peroxidation (LPO), the non-induced LPO was not affected.Further the effect of PC on the products of LPO was investigated in the lungs, livers and sera of intact and influenza virus-infected mice (VIM). The infection enhanced LPO in the lungs and livers. In the group of PC-treated VIM, malondialdehyde (MDA) in the lungs and livers was brought to control levels. PC-treatment caused a significant increase of MDA in the lungs of intact mice, a slight one in the livers and did not affect MDA in the sera. Thus the extract exhibited prooxidant characteristics in intact animals as well as antioxidant properties in VIM. The reducing ability of PC on LPO could be an alternative mechanism of its protective effect in experimental influenza infection. Copyright (c) 2008 John Wiley & Sons, Ltd.

13. Assen Panteva, Stefka Ivanchevab, Lidija Stanevaa, and Julia Serkedjievac,* - Biologically Active Constituents of a Polyphenol Extract from Geranium sanguineum L. with Anti-Influenza Activity

From the aerial roots of the medicinal plant Geranium sanguineum L. a polyphenol-rich extract with strong anti-influenza activity has been isolated. To investigate its active fractions, the extract was partitioned by solvents with increasing polarity. The n-BuOH fraction contained the majority of the in vitro antiviral activity; the EtOAc fraction was the most effective one in vivo. A bioassay-directed fractionation of the n-BuOH and EtOAc fractions was performed to obtain information about the nature of the chemical components of the plant extract, responsible for the antiviral effect. The individual constituents were identified by spectroscopic methods and comparison with authentic samples and by HPLC. The cell-toxic and virus-inhibitory effects of the fractions and some individual polyphenol compounds, found in Geranium sanguineum L., were studied using the replication of representative influenza viruses in cell cultures. This study showed that the presence of a variety of biologically active compounds as well as the possible synergistic interactions between them seem to be decisive for the overall antiviral effect.

14. Serkedjieva J1, Ivancheva S. - Antiherpes virus activity of extracts from the medicinal plant Geranium sanguineum L.

The herpes virus inhibitory effect of five extracts from the Bulgarian medicinal plant Geranium sanguineum L. (Geraniaceae) was investigated. The water extract (WE) from the aerial roots of the plant was the least toxic for cell cultures and inhibited significantly the replication of herpes simplex virus type 1 and type 2 (EC50 = 3.6-6.2 microg/ml) as shown by the reduction of virus induced cytopathogenic effect (CPE) and the protection of cells in MTT assay. The inhibition was dose-related, strain-specific and depended on virus inoculum. In higher concentrations (MIC90 = 120 microg/ml) the preparation exhibited strong extracellular virus inactivating activity. The presence of WE throughout the whole replicative cycle was necessary for the full expression of the antiviral effect. In a preliminary experiment in albino guinea pigs the extract delayed the development of herpetic vesicles following primary infection with HSV-1, strain Kupka. Phytochemical investigation of the plant preparation revealed the presence of flavonoids, catechins, a polyphenolic acid and condensed tannins. The inhibitory effect of the extract on herpes simplex virus replication is related to the rich content of polyphenol compounds.
