Alpha-lipoic acid for nerve pain -

Using this invasive technique, intra-arterial infusion of lipoic acid was found to improve endothelium-dependent vasodilation in 39 subjects with type 2 diabetes but not in 11 healthy controls A more recent randomized , double-blind , placebo -controlled study in 30 patients with type 2 diabetes found that intravenous infusion of mg of lipoic acid improved the response to the endothelium-dependent vasodilator acetylcholine but not to the endothelium-independent vasodilator, glycerol trinitrate Another noninvasive technique using ultrasound to measure flow-mediated vasodilation was used in two additional studies conducted by Xiang et al.

The results of these randomized, placebo-controlled studies showed that intravenous lipoic acid could improve endothelial function in patients with impaired fasting glucose 64 or impaired glucose tolerance Peripheral neuropathy is also a leading cause of lower limb amputation in diabetic patients Several mechanisms have been proposed to explain chronic hyperglycemia -induced nerve damage, such as intracellular accumulation of sorbitol, glycation reactions, and oxidative and nitrosative stress reviewed in The results of several large randomized controlled trials indicated that maintaining blood glucose at near normal concentrations was the most important step in limiting the risk of diabetic neuropathy and lower extremity amputation However, evidence of the efficacy of enhanced control of glycemia in preventing neuropathy is stronger in patients with type 1 diabetes than in those with type 2 diabetes Moreover, this glucose control intervention increased the risk of hypoglycemic episodes The efficacy of lipoic acid, administered either intravenously or orally, in the management of neuropathic symptoms has been examined in patients with diabetes.

Regarding the efficacy of oral lipoic acid supplementation, an initial short-term study in 24 patients with type 2 diabetes mellitus found that the symptoms of peripheral neuropathy improved in those who took mg of lipoic acid three times a day for three weeks compared to those who took a placebo Evidence of improvements in sensory and motor deficits — assessed by physicians — could be observed after three weeks of intravenous lipoic acid therapy, yet not at the end of six months of oral lipoic acid therapy.

Yet, measures of specific neuropathic impairments secondary outcomes improved with lipoic acid supplementation A post-hoc analysis suggested that oral lipoic acid supplementation may reduce neuropathic symptoms particularly in subjects with a high burden of cardiovascular disease , diabetes, and neuropathy yet with normal body mass index BMI and blood pressure CAN is characterized by damage to the nerve fibers that innervate the heart and blood vessels, leading to reduced heart rate variability variability in the time interval between heartbeats and increased risk of mortality Summary: Overall, the available research suggests that treatment with intravenous or oral lipoic acid may help reduce symptoms of diabetic peripheral neuropathy.

The use of lipoic acid is currently approved for the treatment of diabetic neuropathy in Germany 4. It is important to note that many of the studies that examined the efficacy of lipoic acid in the treatment of diabetic neuropathy have been primarily conducted by one German research group and funded by the manufacturer of lipoic acid in Germany Chronic hyperglycemia can damage blood vessels in the retina and cause a potentially sight-threatening condition called diabetic retinopathy One placebo-controlled study examined the effect of lipoic acid on the visual capability of 80 participants of whom 12 had type 1 diabetes, 48 had type 2 diabetes, and 20 were diabetes-free.

The result showed that daily oral administration of mg of lipoic acid for three months prevented the deterioration of contrast sensitivity in patients with diabetes and improved it in healthy patients compared to placebo Multiple sclerosis is an autoimmune disease of unknown etiology that is characterized by the progressive destruction of myelin and nerve fibers in the central nervous system , causing neurological symptoms in affected individuals There are four main types of multiple sclerosis defined according to the disease course: i clinically isolated syndrome, ii relapsing-remitting multiple sclerosis, iii secondary progressive multiple sclerosis, and iv primary progressive multiple sclerosis for more information, visit the National Multiple Sclerosis Society website Lipoic acid was found to effectively slow disease progression when administered either orally 87 , intraperitoneally 88 , or subcutaneously 89 to mice with experimental autoimmune encephalomyelitis EAE , a model of multiple sclerosis.

Only a few studies have examined lipoic acid supplementation in humans. In this study, higher serum concentrations of lipoic acid were associated with the lowest serum concentrations of MMP-9 — a marker of inflammation Another study suggested that an oral dose of 1, mg of lipoic acid in subjects with multiple sclerosis could help achieve serum lipoic acid concentrations similar to those found to be therapeutic in mice Supplemental lipoic acid also decreased the serum concentrations of some IFN-γ, ICAM-1, TGF-γ, IL-4 , but not all markers TNF-γ, IL-6, MMP-9 , cytokines and other inflammation In addition, lipoic acid supplementation did not reduce the severity of multiple sclerosis symptoms, as assessed by the Expanded Disability Status Scale EDSS scoring system 98, It is not known whether oral lipoic acid supplementation can slow cognitive decline related to aging or pathological conditions in humans.

However, the significance of these findings is difficult to assess without a control group for comparison. Interestingly, patients who took fish oil concentrate together with lipoic acid showed no worsening of global cognitive function as assessed by the Mini-Mental State Examination [MMSE] score system over 12 months as opposed to those who took either the fish oil concentrate alone or a placebo A meta-analysis of randomized , placebo -controlled trials found that lipoic acid supplementation in those with high body mass index BMI resulted in significant, yet modest, reductions in weight 9 studies and BMI 11 studies in the absence of caloric restriction except in one study There was no reduction in waist circumference with supplemental lipoic acid 5 studies Substantial weight and BMI reductions with lipoic acid supplementation in overweight or obese subjects were also reported in a prior meta-analysis R -lipoic acid is synthesized endogenously by humans see Metabolism and Bioavailability.

R -lipoic acid occurs naturally in food covalently bound to lysine in proteins lipoyllysine; see Figure 1. Although lipoic acid is found in a wide variety of foods from plant and animal sources, quantitative information on the lipoic acid or lipoyllysine content of food is limited; published databases are lacking.

Somewhat lower amounts of lipoyllysine ~0. Unlike lipoic acid in foods, lipoic acid in supplements is not bound to protein. Moreover, the amounts of lipoic acid available in dietary supplements mg are likely as much as 1, times greater than the amounts that could be obtained from the diet.

In Germany, lipoic acid is approved for the treatment of diabetic neuropathies and is available by prescription Lipoic acid is available as a dietary supplement without a prescription in the US. Most lipoic acid supplements contain a racemic mixture of R -lipoic acid and S -lipoic acid sometimes noted d,l -lipoic acid.

Supplements that claim to contain only R -lipoic acid are usually more expensive, and information regarding their purity is not publicly available Since taking lipoic acid with a meal decreases its bioavailability , it is generally recommended that lipoic acid be taken 30 min prior to a meal see also Metabolism and Bioavailability 8.

R -lipoic acid is the isomer that is synthesized by plants and animals and functions as a cofactor for mitochondrial enzymes in its protein -bound form see Biological Activities. Direct comparisons of the bioavailability of the oral racemic mixture and R -lipoic acid supplements have not been published.

Both isomers were nonetheless rapidly metabolized and eliminated 6 , 8 , In rats, R -lipoic acid was more effective than S -lipoic acid in enhancing insulin -stimulated glucose transport and metabolism in skeletal muscle , and R -lipoic acid was more effective than R,S -lipoic acid and S -lipoic acid in preventing cataracts However, all of the published human studies have used R,S -lipoic acid racemic mixture.

It has been suggested that the presence of S -lipoic acid in the racemic mixture may limit the polymerization of R -lipoic acid and enhance its bioavailability At present, it remains unclear which supplemental form is best to use in clinical trials.

In general, high-dose lipoic acid administration has been found to have few serious side effects. Two mild anaphylactoid reactions and one severe anaphylactic reaction, including laryngospasm, were reported after intravenous lipoic acid administration The most frequently reported side effects of oral lipoic acid supplementation are allergic reactions affecting the skin, including rashes, hives, and itching.

Abdominal pain, nausea, vomiting, diarrhea, and vertigo have also been reported, and one trial found that the incidence of nausea, vomiting, and vertigo was dose-dependent A retrospective observational study reported that daily oral supplementation with mg of lipoic acid racemic mixture during pregnancy and without interruption from a period spanning between week 10 and week 30 of gestation and until the end of week 37 was not associated with any adverse effect in mothers and their newborns In absence of further evidence, lipoic acid supplementation during pregnancy should only be considered under strict medical supervision.

The safety of lipoic acid supplements in lactating women has not been established and should thus be discouraged A case of intoxication was reported in a month old child The child was admitted to hospital with seizure , acidosis, and unconsciousness. Symptomatic management and rapid elimination of lipoic acid led to a full recovery without sequelae within five days.

The non-accidental ingestion of a very high dose of lipoic acid led to multi-organ failure and subsequent death of an adolescent girl In theory, because lipoic acid supplementation may improve insulin -mediated glucose utilization see Diabetes mellitus , there is a potential risk of hypoglycemia in diabetic patients using insulin or oral anti-diabetic agents Consequently, blood glucose concentrations should be monitored closely when lipoic acid supplementation is added to diabetes treatment regimens.

The chemical structure of biotin is similar to that of lipoic acid, and there is some evidence that high concentrations of lipoic acid can compete with biotin for transport across cell membranes , Originally written in by: Jane Higdon, Ph.

It is quickly absorbed from the gastrointestinal tract. It dissolves in both water and fat in the body. ALA is frequently used to treat diabetic neuropathy.

This is a sensory change that includes stinging, burning, pain, and numbness in parts of the skin. ALA hasn't been scientifically proven to be helpful in all cases of neuropathy. However, some studies have indicated its helpfulness in mild to moderate cases. It is used by many people with neuropathy.

Research continues to be in progress to evaluate ALA's effectiveness. Several small studies have also shown that ALA can help to increase insulin sensitivity.

It may lower blood sugar levels in people with diabetes. More research is needed to confirm this. ALA is a strong antioxidant. This function may protect nerve tissue from damage. Conditions, such as diabetes, may be helped by antioxidants such as ALA.

Alpha-lipoic acid ALA fkr a naturally-occurring fatty acid. Your body makes Alpha-lipoic acid for nerve pain own ;ain, but Alpha-lipoic acid for nerve pain is axid available in certain Joint health support system and as a supplement.
