Acetyl-L-Carnitine (ALC)

A major cause of aging is the deterioration of the energy-producing components of the cell which results in reduced cellular metabolic activity, the accumulation of cellular debris, and eventual death of the cell. One of the most effective nutrients to maintain youthful cellular energy metabolism is the amino acid acetyl L-carnitine (ALC), which functions via several mechanisms to protect cells from the effects of ageing. ALC assists in the transport of fat through the cell membrane and into the mitochondria within the cell, where these fats are oxidized to produce the cellular energy ATP.

Acetyl L-carnitine research has shown it promotes a healthy nervous system and memory. ALC activity promotes oxidation which is why it is combined with ALA "

Both young and old rats were treated with L-acetyl-carnitine, a drug which favours the synthesis of acetylcholine, the main neurotransmitter deficient in old age. In aged rats the drug restored a normal number of both axosomatic synapses and giant bouton vesicles. The authors hypothesise that the drug, by a cholinergic-type mechanism, restores the excitatory afferences to the granule whose axon would thus form normal giant boutons with the interneuron, reestablishing the feed-back regulation (Badiali de Giorgi et al 1987). The mechanism for the pathological increase in cell death in the brain that occur in various disease states e.g. HIV, ageing or Alzheimer's disease, occurs by complex and as yet undefined mechanism(s) related to immunological, virological or biochemical disturbances (i.e. energy depletion, oxidative stress, increased protein degradation).

It appears that l-carnitine and its acetylated form, acetyl-l-carnitine, can attenuate the cell damage (Virmani et al 1995). ALC was effective, unlike L-carnitine, in decreasing oxidative damage, including MDA, oxo8dG/oxo8G, and nitrotyrosine, in old rat brain (Liu et al 2004).

Alpha Lipoic Acid

Alpha Lipoic Acid helps defend against degenerative diseases and aging by fighting free radicals. ALA is an antioxidant that regenerates both itself and other essential antioxidants, such as vitamins C and E, and coenzyme Q10. ALA also increases levels of the antioxidant glutathione, which is found in the brain. Insufficient levels of glutathione have been linked to the increased risk of stroke, dementia, Parkinson's and Alzheimer's disease. ALA has also been found to promote liver health. And, in several studies, it has been proven to promote healthy nerve function in diabetic patients

The Alpha Lipoic Acid / Acetyl L-Carnitine combination act as a powerful anti-oxidant and energy booster and together they appear to work better then either one on there own.

Acetyl-L-carnitine is used for Alzheimer's disease, age-related memory deficits, senile depression, Down syndrome, alcoholism-related cognitive deficits, and cerebrovascular insufficiency after stroke. It is also used for peripheral neuropathies, diabetic neuropathy, neuropathy due to anti-viral drugs used in the treatment of AIDS, facial paralysis, male infertility, symptoms of age-related testosterone deficiency, and Personae's disease."  Alpha-lipoic acid is a coenzyme that, together with pyrophosphates, is involved in carbohydrate metabolism and production of adenosine triphosphate (ATP). Exogenous alpha-lipoic acid and the metabolite, dihydrolipoic acid (DHLA), have antioxidant activity and can scavenge free radicals both intra- and extra-cellular.

ALC & R-LA

L-carnitine and α-lipoic acid may offer neurotherapeutic effects (e.g., neurocognitive enhancement) via disparate mechanisms including antioxidant, anti-inflammatory, and metabolic regulation. L-carnitine and α-lipoic acid are pleiotropic agents capable of offering neuroprotective and possibly cognitive-enhancing effects for neuropsychiatric disorders in which cognitive deficits are an integral feature (Soczynska et al 2008).

Codonopsis pilosula radix (CP)

Dang Shen(CP) is a TCM herb to nourish the Center, invigorate qi, generate Fluid and nourish Blood.

Modern research showed that Dang Shen was a tonic, having adaptogenic, anti-fatigue, and anti-ageing and anti-anoxic effects. It could improve the learning and memory of mice, and improve immunity as well. Dang Shen could elevate RBC count, increase amount of hemoglobin and lower WBC count. Extracts of Dang Shen could increase blood flow volume in the brain, lower limbs and internal organs. Dang Shen at different concentrations had inhibitory or exciting effect on isolated ileum of guinea pigs, and had treating as well as preventative and protective effects on gastric ulcers. It also elevated the content of PGE 2 in stomach tissues. Dang Shen could significantly excite isolated uterus of rats, increase plasma corticosterone in mice and elevate blood sugar. It also had anti-inflammatory, anti-bacterial, analgesic, anti-tussive and expectorant effects.

In clinic, Dang Shen is used to treat coronary heart disease, arrhythmia, hypotension, hyperlipemia, chronic bronchitis, neurosis, chronic enteritis, prolapse of the anus, dysfunctional uterine bleeding, malposition of the fetus, fabism, altitude stress and psoriasis, etc.

Dang shen (CP) alcohol extract had the effects of invigorating energy, activating blood flow and resolving blood stasis on rats and anti-ageing on mice.

The time of anti-anoxia, the weight of immune organs (thymus and spleen) on the 7th day and 14th day were measured. The effects of alcohol extract on rats with qi-xu and Blood stasis syndrome showed whole blood viscosity (high-sheer, middle-sheer, low-sheer), plasma viscosity, aggregation indexes of red blood cells, packed red blood cell were decreased significantly and red blood cell electrodeposition time was sped up significantly. The group of high dose of alcohol extract of CP extended the time of anti-anoxia significantly (Xu et al 2008).

With one untreated group as the control to give the normal saline 0. 1 ml/d; the other three groups were administrated with respectively low dose in their drinking water(0.5 g/ml), middle dose( 1.0 g/ml), and high dose ( 1.5 g/ml). 10 days later immune organs’ weight, weight gain, celiac macrophage phagoeytosis and the red cell immunity function were detected, and splenic histology was studied by microscope. Results showed that compared with the control group, spleen index were increased significantly. Additionally, compound codonopsis oral hquids highly enhanced E-C3bRR of mice and decreased E-ICRR significantly. Therefore, it is proved primarily that compound codonopsis oral liquids can influence and regulate the immunity of normal mice.

Immunomodulatory effect of a polysaccharide-enriched preparation of Codonopsis pilosula roots.

Wang ZT, Ng TB, Yeung HW, Xu GJ. Gen Pharmacol. 1996 Dec; 27(8): 1347-50.

A polysaccharide-enriched fraction (CPPS) was prepared from Codonopsis pilosula root extract utilizing a procedure that entailed extraction with aqueous buffer and precipitation with ethanol. 2. After administration of CPPS in drinking water to C57BL/6 mice at a dosage of 10 mg/L for 4 weeks, the splenocytes exhibited lowered mitogenic responses to Concanavalin A (ConA) and lipopolysaccharide (LPS). The in vitro production of reactive nitrogen intermediates was inhibited. 3. However, when oral administration of CPPS was prolonged to 8 weeks, there was a potentiation of ConA-stimulated and LPS-stimulated mitogenic responses. 4. When tested under in vitro conditions, CPPS augmented the mitogenic response of splenocytes to ConA. However, there was no effect on the pinocytic activity of mouse macrophages, nor was there any proliferative activity on mouse melanoma B16 cells.

The effects of Chinese herbs on improving survival and inhibiting anti-ds DNA antibody production in lupus mice.

Chen JR, Yen JH, Lin CC, Tsai WJ, Liu WJ, Tsai JJ, Lin SF, Liu HW. Am J Chin Med. 1993; 21(3-4): 257-62.

Systemic lupus erythematosus (SLE) is an important autoimmune disease with multiple organ system involvement. From preliminary studies, we have found that six Chinese herbs: Atractylodes ovata, Anqelica sinensis, Cordyceps sinensis, Liqustrum lucidum, Codonopsis pilosula and Homo sapiens can improve defective in vitro interleukin-2 (IL-2) production in patients with SLE. In order to investigate the in vivo effects of these herbs, we used NZB/NZW F1 mice, a typical lupus animal model used to test these herbs. It was found that C. pilosula, H. sapiens and C. sinensis could prolong the life span of female NZB/NZW F1 mice and inhibited anti-ds DNA production. Although A. sinensis could prolong the life span of experimental mice, it did not inhibit the production of anti-ds DNA antibody. These herbs may have great potential for the management of human SLE in the future.

Objective To observe the inhibitory action of astragalus injection on apoptosis of hippocampal neurons induced by hypoxia/hypoglycemia and reoxygenation. MethodsHippocampal neurons of neonate rats cultured primarily for eight days were deprived of oxygen and glucose for 0. 5 h and then cultured normally; at the same time, the neurons were treated by astragalus injection. MTT was used to dectect the activities of neurons, the morphological changes of neurons were observed by light microscope and Annexin V-FITC/PI double staining flow cytometry(FCM)was used to examine the apoptotic rate of neurons. ResultsCompared with normal control group, the activities of neurons at each time point of reoxygenation of hypoxia/hypoglycemia and reoxygenation(model)group were decreased significantly(P<0.05), and the activity of neurons at 6 h after reoxygenation was the lowest, there had obvious difference compared with those of other time points(P<0.05). In astragalus injection low and high concentration group, the activities of neurons had no significant difference compared with those of model group at the same time point(P>0.05); while the activity of neurons in astragalus injection middle concentration group was increased significantly(P<0.05). The apoptotic rates of neurons in model group were increased than those in normal control group(P<0.05); while those in astragalus injection groups were markely decreased than those in model group at each time point(P<0.05). In model group, a great quantity of apoptotic and necrotic cells were observed by light microscope; nucleus of apoptotic cells were shrinkaged, fragmented and deep-stained and apoptotic bodies were also observed. In astragalus injection groups, the apoptotic cells were obviously decreased and the main pathological changes were shrinkage of nucleus, and the extent of neorobiosis of neurons were lightened significantly. ConclusionsThe astragalus injection can inhibit hippocampal neurons apoptosis induced by hypoxia/hypoglycemia and reoxygenation and increase the activities of neurons, so it plays a role in protecting hippocampal neurons.

Astragali radix (Huang Qi; AR)

AR increases metabolic rate and cAMP (Zhang Yao...1985) but decreased cGMP in plasma but increased cAMP and cGMP in the spleen and increased cGMP in the liver (Zhong Cheng…1984). AR relieves copper induced oxidative stress and is similar to SOD as a free radical scavenger (Chen & Chen P.852). AR strongly inhibited strongly inhibited p16 and p21 (families of cyclin-dependent kinase (CDK) inhibitors) expression and protects cells against senescence (Wang et al 2008).

Biotin

Biotin is necessary for cell growth, the production of fatty acids, and the metabolism of fats and amino acids. It plays a role in the citric acid cycle, which is the process by which biochemical energy is generated during aerobic respiration. Biotin not only assists in various metabolic reactions, but also helps to transfer carbon dioxide. Biotin is also helpful in maintaining a steady blood sugar level (Santa María et al 2009). Biotin is added as R-LA competes and depletes Biotin levels when R-LA is taken in amounts over 100 mg.

D-Pinitol

D-pinitol (3-O-methyl-chiroinositol), an active principle of the traditional antidiabetic plant Bougainvillea spectabilis, is claimed to exert insulin-like effects.

D-pinitol can exert an insulin-like effect to improve glycaemic control in hypo-insulinaemic STZ-diabetic mice. D-pinitol may act via a post-receptor pathway of insulin action affecting glucose uptake.(Bates et al 2000). D-Pinitol is a methylated sugar that is an isomer, or type of inositol. It is a naturally occurring insulin-like compound, found in pine trees, legumes, and in the flowers and leaves of many plants, which is extremely anabolic and acts as a powerful insulin mimicker. D-Pinitol has recently been subjected to an in vitro study exploring its effects upon living muscle cells. This unpublished study found high concentrations of D-Pinitol to increase glucose uptake and glycogen synthesis in these cells, the former occurring even in the absence of insulin. This latter element suggests that D-Pinitol may exert true insulin mimetic effects, and proper D-Pinitol supplementation will boost post-exercise glycogen synthesis, delivering more nutrients to the muscle cell for fuel, growth, and shortening recovery time.

Biotin is added as ALA competes and depletes Biotin levels when ALA is taken in amounts over 100 mg.
