Alpha

Alpha Lipoic Acid increases antioxidant support. Not only does it affect the body because it is fat and water soluble, but it also optimizes or recycles other antioxidant compounds

Antioxidation
Verified Purchase
I regularly take vitamins C and E for their antioxidant properties, but I learned that taking AlphaLipo helps recycle vitamin C, so I started taking it about 20 years ago. I don't notice any obvious physical changes, but I do notice a significant increase in body temperature on the days I take it. I'm not sure if it's due to increased sweating, but I can definitely feel that my metabolism is improving. This supplement is of excellent quality, contains a large amount of ingredients, and is a product I highly recommend.

Slow-release capsules
Verified Purchase
A good, effective version of alpha-lipoic acid. I take it to feel more energetic and support my metabolism. I've been taking one capsule in the morning with breakfast for about a month now. I've noticed less energy slump during the day, my skin looks smoother, and I feel more stable overall. The capsules are small and easy to swallow. I trust the Carlson brand.

I'm very pleased with the results of taking these vitamins! After just the first week, I felt a surge of energy, and within a month, I noticed a significant improvement in my overall health. The vitamins' composition is impressive—it contains all the essential micronutrients and vitamins in optimal dosages. The capsules are easy to swallow, and I have no doubt about the quality—the manufacturer is reputable and uses only high-quality ingredients. The vitamins have a pleasant, non-irritating taste. They strengthen the immune system, improve brain function, and maintain beautiful skin and hair. I recommend these vitamins to anyone who wants to maintain their health and feel in shape!

I took it as prescribed by a doctor to correct blood sugar levels and reduce appetite. The result is good, I can control my hunger, my portions are smaller, and I have less cravings for carbohydrate foods. So obviously the quality is excellent, the size of the capsules is normal, and the packaging is reliable. I will order more!

Excellent!
Verified Purchase
I bought this to try taking alpha-lipoic acid consistently. It's a timed-release formula, so I like the feeling of it being absorbed slowly throughout the day. I feel comfortable after taking it, and it seems to help maintain energy. I'm also satisfied with the tablet size, which is easy to swallow.
