Stabilized R-Lipoic Acid 100mg

180 Veggie Caps DRB-00229

Get active. 

Our R-Lipoic Acid is supercharged with BioEnhanced® Na-RALA, the active “R” form of lipoic acid. In this case, active means better–it’s more stable and easier for the body to absorb.* Lipoic acid (LA) can support you with healthy glucose metabolism and energy production.* BioEnhanced® Na-RALA is in its natural and stabilized form of RLA that won’t degrade at high temperatures, making it more bioavailable and biologically active. Coupled with D-Biotin, which assists with the breakdown and conversion of fatty acids and carbohydrates into energy, this is a powerful supplement to add to your regimen.*

Best form of ALA Been using this product for over two years with excellent results. Used to use regular ALA which contains both S and R types. Only the R type is most useful to the body so why pay for and use the S type which has limited function. Very satisfied with the quality of this product, combined with the reasonable cost, makes this one of my favorite brands to deliver high quality ingredients. Highly recommended.

Good stuff I love Doctor's Best brand. I researched and found that the R Alpha Lipoic acid is many more times potent than just Alpha Lipoic acid so I only take one where I was taking 3 or 4 of the regular. I am taking it for blood sugar levels, neuropathy in my feet. I have no side effects at all. Wonderful product.

Doctor's Best R-Lipoic works I depend on Alpha Lipoic to help with foot neuropathy nighttime pain and have tried many brands. Doctor's Best R-Lipoic works like no other, even in what would seem to be a lesser dosage than other brands recommend. I don't know if that is attributable to the R-factor or not, but I take one in the morning and one at bedtime and noticed a difference within 6-7 days of beginning this regimen. On one occasion of running out of this supplement, the neuropathy returned full force after about a week, keeping me awake with pain, so I'm careful to order ahead.

Antioxidant power.

Our Lipoic acid is both fat and water soluble, a potent antioxidant that supports mitochondrial function, helps protect against oxidative stress and maintains cellular energy.*

Suggested Use

Each veggie capsule contains 100 mg of R-Lipoic Acid and 150 mcg of D-Biotin. Take one capsule daily, with or without food.


RALA, a small amount of sodium or potassium has been attached to RLA to produce the salt of RLA. In this form, it is much less hygroscopic.

Internal studies by Geronova, the company that produces it, show a higher plasma concentration achieved by this product compared to pure RLA and other lipoic acid products.

Both forms are used to stabilize R-Lipoic acid, sodium form is less hydroscopic.
