R Fraction ALA Triple Strength 300mg

I have been using this product for about 1 year after being diagnosed at 65 years old. R Fraction 300mg is a great product if you have neuropathy. It really helps to keep away the burning pain. When I first did research and read up on it, I wasn’t quite sure. I am a believer now. It works great and I don’t want to ever be without it again. The quality ingredients and benefits are such a relief to me. The 300mg size is perfect for my issue. Hopefully they continue selling it without any change to the ingredients.

The only high absorbant form of ALC

Alpha Lipoic Acid is a big benefit in my struggle to control my blood sugar and diabetic neuropathy. This is a high quality product that I take every morning. It makes a difference along with a healthy diet and exercise. The size of the capsules (300mg) makes it convenient to take a doctor recommended 600 mg.

Swanson makes good products

I bought this because the R -lipoic version of ALA is supposed to be the most bioavailable form. This has a fairly high dose for one capsule (300mg) which makes it easier to reach a higher level without taking multiple capsules. I am taking this for nerve pain and feel that it is helping.

Helps neuropathy

My neuropathy symptoms are improving. I trust Swanson brand as they are third party tested and are manufactured in a GMP facility. The price is good for the more pure, non synthetic R lipoic acid. Buying direct from Swanson when they are on sale may get you a better price.

Best ALA out there!

I’ve tried a ton of ALA brands over the years, but once I switched to a true stabilized R-fraction, this one and everything changed.Way less nerve tingling in my feet. My fasting glucose dropped 15–20 points consistently (results may vary).energy boost in the afternoons – no more 3 p.m. crash even on long workdays.If you have blood sugar issues, neuropathy, or just want the usual “mid-40s fatigue,” do yourself a favor and get the real R-form. Totally worth it. The benefits are notciable. The size isn't too big and the quality is on point.

good​ for​ short​ term

The quality of the product and ingredients is impressive. I’m really happy with it overall. It doesn’tุ upset my stomach and is great for general health support​ but​ It’s suitable for short-term use for detoxification.

R ALA

It is important to me that the ALA I take is natural, not synthetic, so it has to be R-fraction like this one.
