MegaNatural®-BP Grape Seed Extract

1. What is it

Sustained Release MegaNatural®-BP Grape Seed Extract is a dietary supplement that features a standardized grape seed extract formulated to deliver highly concentrated polyphenols, which are powerful antioxidants beneficial for cardiovascular wellness.*

2. Who it's for

This product is ideal for adults actively managing their cardiovascular wellness, particularly those looking to maintain blood pressure already within the normal range through clinically-studied botanical support rather than through conventional approaches alone.

3. How to take it

As a dietary supplement for adults, take one (1) tablet daily with a full glass of water, preferably with a meal, or as directed by your healthcare practitioner.

4. Bonus benefits

Sustained Release MegaNatural®-BP may also support whole-body antioxidant health by helping to neutralize free radicals and protect cells from oxidative damage.*

5. If you really like science

Sustained Release MegaNatural®-BP contains a grape seed extract standardized to 90% polyphenols,, the bioactive compounds responsible for many health benefits. Research indicates that polyphenolic antioxidants can help relax blood vessels, thus promoting healthy blood flow and helping to maintain blood pressure already within the normal range (1). The extract is produced using a patented, water-based extraction method that ensures no harmful solvents or chemicals are present, making it a safe choice for everyday use. Additionally, clinical studies support its effectiveness in enhancing endothelial function and providing cardiovascular support, making it a valuable addition to a health-conscious lifestyle (2,3).*

6. Inactive ingredients

Isomalt, vegetable waxes (rice bran and/or carnauba), stearic acid (vegetable), magnesium stearate (vegetable), silica.

7. Precautions

Consult your healthcare professional prior to use if you have or suspect a medical condition, are taking any medications, or are pregnant or nursing. As with all dietary supplements, keep out of reach of children.

8. Product Quality Control Tests Performed

MegaNatural®-BP SR is manufactured in the United States (Oregon) in a state-of-the-art, FDA-registered facility that meets or exceeds current Good Manufacturing Practices (cGMP). Quality control tests are performed at every stage of the manufacturing process from rigorous raw material testing to finished product testing.

Appreciation for Your Unique Sustained-Release Grape Seed Extract

I am writing to express my sincere gratitude for your continued production of the Sustained-Release Grape Seed Extract.

As far as I am aware, Endurance Products Company is the sole manufacturer willing to undertake the significant technical challenges and costs required to produce this specific formulation.

While other brands opt for standard immediate-release capsules, your commitment to the SmartMatrix™ technology ensures a superior absorption profile that mimics the body’s natural digestion.

I deeply value the extra effort, specialized equipment, and scientific rigor your team invests to keep this unique product on the market.

It is a rare example of quality and innovation over convenience, and it makes a tangible difference in my health regimen.

Thank you for not taking the easy path!

Best Regards,

From a very happy multi-year customer

P.S.:

With a tablet cutter I even spread the intake evenly throughout my day.
