Alpha Lipoic Acid is not a medication, therefore there is no prescribed dose. Those who are familiar with the supplement recommend a daily maintenance dose of between 50mg to 100mg in most cases.
Therapeutic dose: The amount of alpha lipoic acid used in research has ranged from 150-600 mg per day, with 600 mg per day being used to treat diabetic neuropathies and 150 mg per day for glaucoma.
HIV clinical studies have used 300 to 750 mg of alpha lipoic acid per day. However, patients exceeding the maintenance does must do so under the supervision of their physician. Some clinicians have reported that their patients experienced improved energy levels on doses of 500 to 800 mg a day.
Again, it should be remembered that these are suggested doses only. The FDA does not have an established recommended daily requirement for Alpha lipoic acid.
Alpha lipoic acid (ALA) as a health supplement was first introduced to the mainstream market during the late 1980’s/ early 1990’s.
As a chemical compound, structurally, alpha lipoic acid contains sulfur. As such, ALA supplements take the form of yellow, crystalline powder (sulfur is yellow). Alpha lipoic acid supplements are usually sold loose as a powder, in capsule form or pressed into a tablet.
Since the introduction of these supplements, alpha lipoic acid has become increasingly popular with body builders and other people who exercise, in addition to those with medical conditions ALA can be used to help treat. Some suppliers of alpha lipoic supplements claim that it increases performance as it helps the body take glucose from the blood and transfer it into the muscle as at an increased rate.
Whatever the motivation for using alpha lipoic acid, supplements are a convenient way of taking extra ALA than through the diet alone.
Whilst many foods contain alpha lipoic acid, the levels are usually extremely low as are absorption rates.
By taking alpha lipoic acid supplements a higher amount can more easily be consumed and absorbed by the body. Around 30 to 40% of oral doses of alpha lipoic acid are absorbed [13,.
Taken as a general health supplement, alpha lipoic acid receives generally positive responses.
One notable comment is that ALA may degrade quickly when exposed to air and light. ALA in powered form should be kept in dark, tight fitting containers or the powder put into capsules.
To increase the degree of absorption, alpha lipoic acid should not be mixed in with a high volume of liquid and should be taken on an empty stomach.
