What Are the Most Powerful Antioxidant Supplements?
Here is a Top 6 list of the best antioxidants:
- Coenzyme Q-10 (Ubiquinol)
- Alpha Lipoic Acid (ALA)
- Vitamin C
What are Antioxidants?
Antioxidants are powerful compounds that slow down the oxidation process. Oxidation is a chemical reaction that can create free radicals. Free radicals can cause damage and inflammation to your cells.
What are the benefits of Antioxidants?
It’s well known that those on a Ketogenic Diet will sometimes develop high cholesterol. We have to stop thinking of “high cholesterol” as a dirty word. It’s the inflammation and oxidation that causes cholesterol to oxidize and form plaque.
Glutathione is the master antioxidant, but it is unclear whether taking exogenous glutathione actually raises the body’s glutathione levels. Glutathione is poorly absorbed by the body according to the study. As you can see it’s also very expensive, so I didn’t include glutathione in my top 6 list of the best antioxidants.
Keto Diet and Fatty Liver
So if you want to read more about NAC and how it can detoxify your liver I would highly recommend that article.
The ingestion of vegetable and seed oils are one of the leading causes of oxidation. That is why the type of fats we eat on the Ketogenic Diet is so important.
There are literally hundreds of different antioxidants, but after extensive research, these (arguably) are the top 6 most powerful antioxidants to support a Ketogenic Diet.
It’s safe to say that Astaxanthin is the best antioxidant for the skin.
This study from the US National Library of Medicine shows astaxanthin is especially good for the skin, reducing wrinkles, age spots and improving moisture and elasticity. The study further goes on to give astaxanthin credit for protecting the skin against radiation damage. Astaxanthin (ASX) appears to be a natural sunscreen.
The beauty of ASX is it has been shown to be effective at relatively low doses of between 6-12 mg. However, ASX should be consumed together with dietary fats to optimize bioavailability.
ASX pairs well with krill oil. The omega 3 fats in the krill oil are also good for your skin and work synergistically with astaxanthin. This combination will help you speed up your keto results and look better in the mirror.
ASX is really keto friendly because as we lose weight on the ketogenic diet we tend to develop loose skin. Astaxanthin can help keep the skin tight, supple and elastic.

- Brassica vegetables
- red wine
Coenzyme Q-10 (Ubiquinol)
CoEnzyme Q-10 (CoQ10) is probably the most common antioxidant out available. Also known as ubiquinone, it gained its popularity along with the massive increase in the prescription of statin drugs. Statins are well known to deplete CoEnzyme Q-10 and doctors quite often recommend CoEnzyme Q-10 supplements along with statins.
It helps provide energy to the mitochondria. Coenzyme Q10 also benefits people with heart failure, high blood pressure, gum disease, Parkinson’s disease, and muscle weakness and pain associated with statin drugs.
Food sources for Resveratrol and Pterostilbene are:
Resveratrol and Pterostilbene are best when taken together. They provide a synergistic effect. Resveratrol has been around a while, but pterostilbene is the powerful newcomer. Pterostilbene is much more potent, (80% more bioavailable) than resveratrol.
In this study titled, “Neuroprotective action of Resveratrol.” Resveratrol has been shown to increase the clearance of beta-amyloid, a leading contributor to Alzheimer’s disease.
The link between calorie restricting (fasting) and aging is still emerging, but preliminary studies show fasting can increase longevity and health by stimulating sirtuins.
Yes, fasting might be the fountain of youth we’ve been looking for. Read this study for more information on sirtuins and aging.
Similar to fasting, pterostilbene has shown to activate sirtuins (Sirt1) and may be able to extend lifespan and provide protection against the health decline associated with aging.
Pterostilbene is commonly referred to as the “fasting mimicking supplement.” You can read all about this amazing antioxidant at pterostilbene.com.
Why should pterostilbene and resveratrol be taken together?
Not only pterostilbene and resveratrol but quercetin also. It looks like when you take all three antioxidants together they have a powerful effect.
This study from Springer Link showed even at low doses, resveratrol, pterostilbene, and quercetin synergistically lessened oxidative injury of membrane lipids.
Pterostilbene has a much longer half-life and is much more bioavailable, but resveratrol activates more sirtuins. So when taken together they have a good 1-2 punch.
Alpha-Lipoic Acid is one of the best antioxidants available as a supplement. It has been shown to improve insulin sensitivity, reduce inflammation, improve skin elasticity and protect against neurogenerative diseases.
Acetyl L- Carnitine and Alpha Lipoic Acid
Every stone I overturned told me vitamin C is an amazingly under-rated antioxidant. Pubmed has 62,468 published studies on Vitamin C.
Vitamin C is a water-soluble vitamin so it has to be replenished daily. Don’t worry about getting too much because excess amounts of the vitamin pass from the body through urine. Vitamin C is needed for the growth and repair of bodily tissues. It works with collagen to make and repair teeth, bone, cartilage, skin, tendons, ligaments, and blood vessels. It also helps the absorption of iron.
Vitamin C is one of the oldest supplements in humankind history. Centuries ago, sailors frequently died of scurvy because vitamin C was in short supply on most ships.
In 1933 Dr. Szent-György synthesized vitamin C. He produced three pounds of pure crystalline vitamin C from the spice paprika.
In 1937, he was awarded the Nobel Prize in Physiology or Medicine “for his discoveries in connection with the biological combustion processes, with special reference to vitamin C.”
New Studies on Vitamin C
This study on Pubmed showed vitamin C significantly reduced glucose concentrations in patients with type 2 diabetes if taken greater than 30 days.
Vitamin C is predominantly found in fruit and those of us on a Ketogenic Diet eat very little fruit.
Many of us on the ketogenic diet don’t eat fruit and not enough vegetables. Vitamin C is a mandatory nutrient and must come from dietary sources. For those of us on a ketogenic Diet supplementing with vitamin C is highly recommended.
These are the antioxidant dense foods with the highest Vitamin C content:
- Bell Peppers
- Brussels Sprouts
- Bok Choy
- Swiss Chard
