Review: Hit the Spot - Also known as Tiger Cane, this plant has been giving me life for awhile now. Wish that it still had the organic certification, but i trust my body's response to things, and this is definitely one of the better quality Knotweed suppliers out there. Pairs well with NMN, TMG and sirtuin-rich foods like black currants.
Review: Not tasty, but effective :) - I use to take really expensive resveratrol supplements as high cholesterol and heart disease runs in one side of my family. I've noticed that my resveratrol supplements, over time, have gone from using grape seed skin or extract to polygonum cuspitadum. Out of curiosity, I googled polygonum cuspitidaum and went down a rabbit hole! Apparently, japanese knotweed is a fast growing, invasive weed that people spend a lot of time on to get rid of. Yet it contains the most natural resveratrol out of any plant or fruit source. Oh the irony. Not sure if you have read my other reviews, but I'm big on prepping my own supplements these days. The knotweed that you get from Nature Restore tastes horrible. Bitter and funky at the same time. But that's when I know it's the good stuff, because Mother nature doesn't make healthy stuff for you that taste like jello. I'm not sure how you prep it if you plan on eating it directly but you'll need a good strong flavor mask, maybe some oolong tea?

## Features

- NON-GMO Japanese Knotweed powder, natural source of resveratorl.
- BENEFITS | Japanese knotweed is naturally high in trans-resveratrol and emodin. Many people also use knotweed for other health benefits.
- INDEPENDENTLY TESTED | In our first attempts to source knotweed, we found lead and arsenic way above FDA guidelines. We could not have that! Rest assure you're getting an organic knotweed powder well within heavy metal limits. Make sure your polygonum supplement is safe!
- NOTE! We are in the middle of a new organic certifier but the process will take most if not all of 2025 but rest assured, you are still receiving the same Japanese knotweed. Our Japanese Knotweed is pure unadulterated powder. There are plenty of ways to mask the bitter taste of knotweed, check out our website for recipes
- 8-ounce jar, 90-120 Servings Per jar, Recommended Serving Size 1/2 teaspoon. Strong bitter taste profile, we recommend masking it in a full flavor smoothie/coffee/tea or as a DIY capsule.

## Questions & Answers

**Q: what is it's potency?**
A: Hello, it's a straight powder blend so there's no standardization to any bio-actives

**Q: Is the actual knotweed organic? It never says organic knotweed on ingredient list, just org tapioca. Even on list here on page it is not organic? Tks**
A: This brand was suggested to me by my friend who eats organically so I didn't question the ingredients. If you can't find it to be organic, except for the name, then I guess it's not organic as advertised.

**Q: Is it made from the root of the plant?**
A: Yes, technically the root system is called 'rhyzome'.

**Q: This has been asked but wasn't answered correctly. How many milligrams of resveratrol is in 1 gram of this Japanese Knotweed powder?**
A: Hello,

Unfortunately, we do not standardize to trans-resveratrol and cannot specify how much is in 1 gram.

### ⭐⭐⭐⭐ Good stuff.
*by A***W on February 5, 2017*

Great source of resveratrol. I wish I know how much trans resveratrol was actually in each serving. You see, there is resveratrol and trans resveratrol. Trans is canceled out by its other half. You want as much trans as possible without getting the other kind. That being said, the taste is like a spice. I've made ginger cookies with it and chocolate chip. I used about one slightly heaping teaspoon to the mix. I have also added 1/4th of a teaspoon in my cereal. It dissolves great after stirred and doesn't linger. I has no taste in the cookies since it's so little. It also actually taste good if lightly sprinkled on whatever you like (cereal is actually really good). Now listen. The serving size is around 1/8th of a teaspoon here. I forget, but I think it's 500mg of total resveratrol. If you use a full teaspoon, you're going to be getting around 3000mg or 3g. This is completely ok to do, but you will get a strong flavor and it wont be great unless you're really into that flavor. If you are taking this as part of a chemo regiment, I suggest stirring it in chocolate milk and downing it. It'll dissolve all the way and it wont taste HORRIBLE. It wont be amazing, but manageable.
