Heart Health Supplements That Work

Resveratrol is a polyphenol antioxidant that supports cardiovascular health by improving arterial dilation, boosting Nitric Oxide production, and reducing oxidative stress. Mega Resveratrol's pharmaceutical-grade trans-resveratrol is micronized for superior absorption, making it significantly more bioavailable than standard resveratrol supplements on the market.

Both NMN (Nicotinamide Mononucleotide) and NR (Nicotinamide Riboside) boost NAD+ levels, which decline with age and contribute to reduced cellular energy. NMN is a direct NAD+ precursor and may act faster, while NR activates sirtuins for DNA repair. They can be used together with resveratrol for synergistic cardiovascular and longevity benefits.

Yes. Every Mega Resveratrol product is independently certified by a US laboratory for purity and potency. Certificates of Analysis are publicly available. Products are manufactured in a GMP-certified, FDA-regulated facility in the USA with no excipients, fillers, or synthetic ingredients, ensuring you receive exactly what is on the label.

Pterostilbene is a natural polyphenol closely related to resveratrol but with enhanced bioavailability. It is studied for antioxidant and cardiovascular benefits and is often used alongside resveratrol to amplify its effects. Mega Resveratrol's 99% Pure Trans-Pterostilbene is micronized for optimal absorption and is trusted by over 100 research institutes worldwide.

Yes. Combining trans-resveratrol, NMN or NR, and pterostilbene is a popular regimen for cardiovascular and longevity support. These compounds have complementary mechanisms — resveratrol activates sirtuins, NMN and NR boost NAD+, and pterostilbene enhances antioxidant protection. Always consult a healthcare provider before starting any combination supplement regimen.

You can use the Longevity NAD Level Test Kit — an at-home intracellular blood test that measures your current NAD+ levels. Results are available in 10–12 days and can guide your supplementation strategy with NMN, NR, or resveratrol. This helps personalize your heart health regimen based on actual cellular data rather than guesswork.
