My husband used to suffer from severe seasonal allergies and bad, achy knees. I used to be wearing cold sores on my lips a lot, and we both used to get colds and the flu too often to our tastes.
I really like the “used to” parts of the above paragraph. Let me share with you how we turned those and other bad realities into mere bad memories…

My Isotonix OPC-3 Story
Chuck and I discovered Isotonix OPC-3 in early 2004. We were told it was the champion in relieving inflammatory symptoms, such as allergies, arthritis, any other -itis, and others. Since we had a few of those between us, we decided to give OPC-3 a try.
Chuck used to suffer from seasonal allergies, sometimes so severe that he’d almost lose his hearing in one ear. He’d go through his initial prescription of Flonase and 5 or more refills each allergy season. After 2 or 3 years on OPC-3, one Flonase nasal inhaler would last him a year! The last few years he hasn’t even bothered to renew the prescription.
Chuck also used to have really bad knees. The joint pain was so bad that he had to stop running. Thanks to OPC-3 his knees don’t bother him anymore. He actually ran a marathon a few years ago, and did a lot of tile and hardwood installing on our floors both up north and in our new house and his workshop in North Carolina. Haven’t heard him complain about his knees once!
Chuck’s colds and flus are also for the most part gone. He occasionally wakes up with a scratchy throat, so he doubles his dose of OPC-3 for a couple of days. Not only does the scratchy throat go away, he also ends up with so much extra energy that he stays up a lot later than usual without feeling tired at all! Maybe he should be doubling his OPC-3 all the time…
Market America claims that OPC-3 “helps reduce mild menstrual cramping and abdominal pain.” Well… mine were no mild cramps. They used to be so severe that I would be rendered useless for 2 or 3 days each month, and while I may have not howled, I would often cry out of pain. These symptoms disappeared completely a few months after I started taking OPC-3. I wish I had found it 25 years earlier!
Also, before OPC-3, I used to get the flu or a bad cold at least 2 or 3 times each year. Some of them would keep me in bed for a week at a time. I have had the flu ONCE in all my years on OPC-3! Other than that, I occasionally wake up feeling like I’m coming down with something, but I double my OPC-3 dose and the “bleh” feeling is gone by the time I finish breakfast.
Another “perk” — my cold sores are all gone. I used to be getting them every 6 weeks or so, and they would linger for a couple of weeks at a time, making it very difficult for me to speak, eat, drink or brush my teeth. I did get 2 or 3 cold sores after I started taking OPC-3, but they disappeared after just a few days, and they happened a long, long time ago.

Isotonix OPC-3 Information
“OPC” stands for oligomeric proanthocyanidins — now you say this ten times fast! (Don’t feel bad, it took me about 3 years to learn to pronounce this right…)
OPCs are the most potent antioxidants known to science, and may help slow down aging and prevent chronic, degenerative diseases, such as allergies and arthritis, for example. More about this another time.
Composed of five super-potent antioxidants — extracts from grape seeds, red wine, pine bark (pycnogenol), bilberry, and citrus — Isotonix OPC-3 offers unparalleled protection from aging- and disease-causing free radicals.
Another quality that sets Isotonix OPC-3 apart from other antioxidants is its isotonic formula. It offers the maximum health benefit by enabling your body to absorb about 95% of all nutrients it contains in just a few minutes. In contrast, most pills, tablets and capsules only give you 10% to 70% absorption rate, often over many hours.
The high absorption rate is crucial here, as OPCs are particularly difficult to digest when acquired from foods or taken in non-isotonic formulas. If you don’t absorb a nutrient, it won’t benefit your health.

How Do You Dose Isotonix OPC-3?
Before I tell you how many doses of OPC-3 you might need, let me explain how to make them!

Each bottle of OPC-3 comes with a small cap and a large cap, as shown above. To make 1 serving (dose), mix ONE SMALL capful of powder with HALF of the LARGE capful of water (use the white mid-cap line painted on the large cap).
If you need a larger dose of OPC-3, multiply both the small powder capfuls and the large water half-capfuls by the same number so you maintain the correct proportions and the isotonic quality.
Some customers who live in humid climates complain that the bottle may become messy and the powder may cake. To avoid this:

For best results, be sure to take OPC-3 on an empty stomach, with room temperature, preferably filtered water.
If you’re taking a single dose, take it on an empty stomach, first thing after you get up. If you’re taking multiple doses, you can take them all at once when you get up, or some before breakfast and the balance before another meal or before bed time, whenever your stomach is the emptiest.
To avoid forgetting about your second round, it’s best to take all of your doses first thing.
Dosage
Typically, the recommended daily dose is 1 serving per 75 pounds of your body weight during the first week. After that you can lower the dose to 1 serving per 150 pounds of your body weight per day.
If you have a chronic, inflammatory disease (such as severe allergies, for example), it is recommended that you take 1 serving per 75 pounds of your body weight plus an additional serving “for the disease” — and continue to do so beyond the first week, as long as needed. You can lower your dosage once the symptoms subside.
Don’t like math? The following chart will help you determine your dosage:
| Your body weight | Prevention First week |
Prevention Maintenance |
If you’re ill First week & on |
| Up to 75 lbs | 1 serving | 1 serving | 2 servings |
| 76 to 150 lbs | 2 servings | 1 serving | 3 servings |
| 151 to 225 lbs | 3 servings | 2 servings | 4 servings |
| 226 to 300 lbs | 4 servings | 2 servings | 5 servings |
| 301 to 375 lbs | 5 servings | 3 servings | 6 servings |
| 376 to 450 lbs | 6 servings | 3 servings | 7 servings |
| 451 to 525 lbs* | 7 servings | 4 servings | 8 servings |
|
* I’m ending the chart at this range because it includes the heaviest participants of TV’s The Biggest Loser (woman 476 pounds and man 454 pounds). Continue adding extra OPC-3 doses if you weigh more than 525 pounds. If you’d like help losing weight, visit my Slender & Healthy website or send me a message. |

Is OPC-3 For You?
DISCLAIMER: OPC-3 is likely to relieve your symptoms but is NOT guaranteed to treat your disease. Do NOT stop taking your prescribed medications without consulting your doctor first!
Isotonix OPC-3 is Market America’s best selling product. Millions of people believe it’s right for them.
However, YOU are not millions of people, YOU are YOU, and your body may be different. The best way to find out if Isotonix OPC-3 is right for you is to print the information about it and take it to your doctor. Also feel free to send me your questions. I’ll be delighted to answer them for you so you can have a more efficient consultation with your physician afterwards.
Also, be aware of the following contraindications to taking Isotonix OPC-3.
OPC-3 has mild blood thinning qualities, therefore you should NOT take it if you are on a prescription blood thinner. Alternatively, you can discuss this with your doctor and find out if reducing the dosage of your blood thinner while taking the full or reduced dose of OPC-3 could be an option for you.
Discontinue taking OPC-3 temporarily in the following circumstances:
- For about a week before any surgery (including tooth extractions) and until all desired blood clots have formed (typically, this doesn’t take long, ask your surgeon or dentist if in doubt). OPC-3’s blood thinning action could interfere with blood clotting. On the upside, taking OPC-3 not long after the surgery may help relieve the pain.
- For about a week before any transplant surgery and until it’s certain that the transplant has been accepted by your body (could be as long as a year). OPC-3 boosts your immune system. While this can help improve your overall health, it could also cause transplant rejection. It’s best to discontinue all antioxidant supplements until your body fully accepts the transplant.
If you have any other medical concerns, consult your doctor before you consider taking any new supplement.
