Product Overview

  • Science-Base Nutrition
  • Dietary Supplement
  • Featuring BioEnhanced Na-RALA
  • Defends Against Free Radicals
  • Recycles the Antioxidants Vitamins C & E
  • Maintains a Healthy Blood Sugar Level as Part of the Diet
  • Suitable for Vegetarians

Best Stabilized R-Lipoic Acid contains BioEnhanced Na-RALA, the sodium salt of R-Lipoic acid (RLA). Unlike pure RLA, BioEnhanced Na-RALA is a stabilized form of RLA that won't degrade at high temperatures, is more bioavailable than regular RLA and has no solvent residues.

Lipoic acid (LA) plays an important role in glucose metabolism and energy production. Because it is soluble in both water and fat, LA is known as the "universal antioxidant." LA occurs in two forms, designated as "R" and "S". Studies suggest that RLA, the natural form, is more biologically active than the S form.

Suggested Use

Adult Use: Take one to two capsules daily, or as directed by a nutritionally informed physician.

Other Ingredients

Modified cellulose (vegetarian capsule), rice powder, microcrystalline cellulose, sodium bicarbonate, magnesium stearate (vegetable source), silicon dioxide.

Contains nothing other than listed ingredients


Note: The RLA in this product is stabilized with Na (sodium). However, one serving of this product contains less than 1% of the Daily Value for sodium, an insignificant contribution to dietary sources. Research suggests that sodium may impact blood pressure in some individuals only when it is consumed as sodium chloride (NaCl, table salt) and not in other forms. The sodium in this product is unlikely to affect blood pressure levels.

Doctor's Best, Stabilized R-Lipoic Acid, 100 mg, 180 Veggie Capsules

Posted by noneofyourfrigginbusiness on Mar 08, 2012

R-Lipoic Acid is exceptionally suitable for supporting the retina of the eye because it can enter the mitochondria, recycle other antioxidants, and is regenerated by high blood sugar. R-Lipoic Acid can help protect the nervous system from the damaging effects of unhealthy blood sugar metabolism, it appears to support healthy glucose uptake and utilization directly.

The best form of Lipoic Acid

Posted by Reviewer1317707 on Aug 29, 2010

Since I have been taking this particular form of Lipoi Acid, I am always in a good mood and have no brain fog. It was so bad that sometimes I could not even find my words.... I am 35 yrs old!

After I waited over 4 weeks for the shipment to arrive, I wanted to give it some time before reviewing it. I must say, it is a great product. First of all it gave me energy and it also took care of a hormonal head-egg in 15 minutes after taking it, which I did not expect!The only drawback is, that it can be giving you a bad burning sensation in your stomach after taking it and you have to drink several glasses of water to cease the burning effect. It does not do this all the time. Sometimes I feel nothing at all. The therapeutic dosage is 600mg. I slowly worked myself up to 500mg and soon I will take 600mg in divided doses over the day. I must say, I am very happy with this product!

Its an important supplement for anti-oxidant support. This is the highest quality for the price of any lipoic acid I've found.

R-Lipoic Acid

Posted by Reviewer1841745 on Nov 24, 2010

Seems to be working. I take it along with GlucoCare for blood sugar control. My readings have been very good. Doctor said to keep doing whatever it is I am doing!
