Knotweed

Japanese Knotweed is a botanical powerhouse known as the primary natural source of Resveratrol. While often considered a garden pest, its root contains a potent antioxidant that supports heart health, brain function, and cellular longevity. Unlike the grape, which contains tiny amounts, Knotweed offers a concentrated dose of nature's anti-aging secret.

Health Benefits & Sources

Why You Need It

  • Antioxidant Power: Neutralizes free radicals that cause aging and cellular damage.
  • Cardiovascular Support: Helps maintain healthy blood pressure and protects blood vessels.
  • Cognitive Protection: Supports memory and protects brain cells from stress.

Deep Dive

Resveratrol works by activating proteins called sirtuins, which are often referred to as 'longevity genes.' These proteins regulate metabolic health and cellular repair. By fueling these pathways, Knotweed extract doesn't just mask symptoms; it supports the body's underlying defense systems.

Natural Food Sources

While red grapes contain Resveratrol, the concentration is very low. You would need to eat kilograms of grapes to match a supplement. Japanese Knotweed root is the most concentrated natural source available.

Supplementation

Because food sources are inefficient for therapeutic doses, supplements are the preferred method. Look for 'Trans-Resveratrol' on the label, as this is the active form your body can use.

Frequently Asked Questions

A glass of wine has about 1-2mg of Resveratrol. To get the benefits seen in studies (150mg+), you would need to drink 70+ glasses of wine. Knotweed extract is a safer, alcohol-free way to get the dosage.
It may support metabolic health and insulin sensitivity, which can aid weight management efforts, but it is not a magic fat burner.
The plant itself can be invasive, but the purified extract is safe. It is not the same as the toxic plant 'Pokeweed'.
Yes! In fact, Vitamin C can help regenerate Resveratrol in the body, making them a powerful antioxidant duo.

Safety & Side Effects

Safe for most adults. High doses may deplete Vitamin B2 (Riboflavin). Avoid if pregnant, breastfeeding, or if you have a history of estrogen-sensitive cancers. Use caution if taking blood thinners.
