Alpha Lipoic Acid is an over the counter Omega 3 fatty acid derived from linseeds with antioxidant properties. It has been shown in some tests to reduce inflammation and prevent nerve damage:
I take 1200mg once a day.
This is what a trusted supplier, Multiple Supplements says:
Lipoic acid is a powerful antioxidant so it has remarkable benefit for you aside from any MS benefit. However with regard to MS specifically, it is thought that lipoic acid may have have an anti-inflammatory effect and may alter your immune response in a way that protects you from damage to your nerves (in other words a neuroprotective function). There are ongoing trials to confirm the link between lipoic acid and those benefits - just have a look at this research page.
ALA is an acronym for alpha lipoic acid and as an acronym for alpha linolenic acid. Careful, they are not the same thing. Alpha linolenic acid is an essential fatty acid and is found in flaxseed oil but it's not what the research has focussed on. Also, if you are also Biotin, this and Lipoic acid use the same uptake mechanism in the small intestine and so if you take them together they will interfere with each other’s absorption into your body. So best to separate them with a meal. What I do is take my biotin with a glass of water when I first wake up in the morning. I then take my Lipoic acid just before lunch.
