With up to 100 times the free-radical-fighting power of nearly every land-based antioxidant…this Seanol® supplement helps:

  • Promote healthy LDL and triglyceride levels
  • Increase beneficial HDL cholesterol levels
  • Promote normal blood pressure and circulation
  • Maintain strong, flexible blood vessels
  • Support sharp brain function
  • Boost your energy…with no side effects

Up until now, some of the strongest antioxidant nutrients we relied on for fighting aging came from green tea and red wine. But now, South Korean researchers have discovered a sea-based antioxidant that’s far more powerful—Seanol. Not only does it benefit your heart, it helps your cholesterol, blood pressure, joints, brain, and more!

Oxygen radical absorbance capacity (ORAC) is a measurement of antioxidant power, and Seanol out-performs just about every common source of antioxidant by leaps and bounds!

Deep-sea discovery. Power-packed strength.

This natural, powerful anti-aging solution was discovered off the coast of South Korea over 2,000 years ago. It’s called, Ecklonia cava—an extraordinary medicinal seaweed. And thanks to a $39 million research project, a precise extract of the seaweed, Seanol, has been shown to have Herculean antioxidant strength—packing up to 3,300 times the anti-aging power of some of the strongest antioxidant nutrients.  

This Seanol supplement also lasts longer in your body, ensuring you feel younger, healthier, and more energized every hour of your day.

“With Seanol, I also noticed a big difference with peace of mind, focus and also a noticeable difference in my overall health and appearance.” — Steve S.

Naturally promotes healthy circulation and blood flow

“Best blood readings I’ve ever had…” — Phillip G.

Healthy blood pressure is critical to your overall health—and it’s something we all have to watch. Ideally, you want to keep your blood pressure at 120/80, or even a bit lower—and Seanol is one of the best natural ways to do just that!

Plus, Seanol’s impressive antioxidant abilities help keep the walls and endothelial lining of your arteries healthy and flexible by stopping free-radical damage. All of these benefits promote healthy circulation and blood flow, ensuring nutrients and oxygen get delivered throughout your body for outstanding overall health.

The perfect trifecta for improving your cholesterol

The name of the game isn’t just to lower your cholesterol—but to get it into the right ratio by raising the “good” HDL, lowering the “bad” LDL, and reducing your triglyceride levels. And with this powerful antioxidant Seanolsupplement, you can do just that!

Seanol is the only supplement I know of that has such a positive effect on HDL and LDL cholesterol, triglycerides, blood pressure, circulation, oxidation, and inflammation enzymes…all at the same time! I haven’t been this charged up about a nutritional health booster since CoQ10!” — Dr. Stephen Sinatra, M.D.

Boosts brain and joint health, and overall energy

In addition to all its cardiovascular benefits, this Seanol supplement works to keep your brain healthy, sharp, and safe, by delivering its unrivaled antioxidant power to your brain. Plus, specific research indicates that taking Seanol increases your brain’s alpha waves, keeping you alert, but calm, and also improves blood flow to your brain.

But not only does Seanol improve your brain health, it also helps reduce inflammatory enzymes that contribute to joint and muscle pain. Plus, Seanol can also provide a safe, natural, side-effect-free energy boost when you take at least 900 mg per day (three capsules). Clinical study participants taking this amount experienced a significant increase in stamina and endurance, and felt more energized for longer.

Seanol is a momentous breakthrough in antioxidant power with far-reaching effects throughout your body. From your heart and your blood vessels to your brain, joints, and energy levels, Dr. Sinatra’s Seanol supplement brings antioxidant power and targeted benefits with long-lasting results.

I have an eight month supply of Seanol, not 30 days. I'm able to walk greater distances now than in the past. I'll chalk part of it up to the fact that I have lost 20 pounds in the last 50 days. We'll see what transpires in the coming months.

I have used this product for many years. After taking 2 capsules daily for 3 months, my triglycerides dropped [significantly]. Since my grandmother had a stroke I did not want to take Statin drugs. I am a big supporter of Dr. Sinatra products and have seen how they have helped my over-all health.

This has worked miracles for my husband. He went from a "don't want to get out of bed" guy to "can't wait to see what this day will be like"kind of guy. He takes one in the A.M. and one in the mid afternoon. This is one supplement we will never give up!
