Quintessential™ takes quinclorac performance to the next level and is an excellent choice if you are going after crabgrass that has invaded your lawn. This is a selective, post-emergent herbicide that can be safely applied to many types of turf to control a variety of broadleaf and grassy weeds, including crabgrass, foxtail, signal grass, and torpedo grass.

  • Up to 90-day control for both broadleaf and grassy weeds
  • Active Ingredients is Dimethylamine salt of Quinclorac 18.92%
  • Unique, patent-pending formulation powered by H-Value Technology, a proprietary performance additive that increases efficacy
  • Great for controlling crabgrass, including the mid-tiller stage of growth
  • Available in multiple sizes *

Product Description:

Quintessential alters the formulation of quinclorac in a way that improves the absorption of the product into the plant. That means faster activity and higher rate load in the targeted weed, as well as improved performance in drought stress or rainfast situations. And unlike any other herbicide on the market, Quintessential demonstrates improved control of crabgrass at all growth stages, including the problematic 3-5 tiller stage.

This product can be applied to both residential and non-residential turf. Selective control means it doesn’t harm turf.

Quintessential can be applied from seven days prior to seeding and up to twenty-eight days after selected weeds have emerged. The use of methylated seed oil, such as Duo Stick Select is recommended to enhance the effectiveness of the product. If you cannot get methylated seed oil, a non-ionic surfactant can be used.

Target pests include Barnyardgrass, Black medic, Foxtails, Clover, Crabgrass (large & smooth), Daisy, Dandelion, Morningglory, Wild Violet, and more.

Surprisingly Great for Diarrhea + Dropped My LDL Big Time – Sugar-Free Winner!
Size: 2.3 Pound (Pack of 1), Style: Sugar Free 180 count
I started taking this Metamucil Sugar-Free 4-in-1 Psyllium Fiber mainly because I deal with diarrhea more than constipation (opposite of what it's usually advertised for). I was skeptical, but it worked amazingly well—firms things up, reduces urgency and frequency, and gives me normal, regular bowel movements without any cramping or worsening. It's gentle, mixes okay in water (orange flavor is tolerable, not too sweet since it's sugar-free), and I take 2 teaspoons daily. Even better bonus: after a few months of consistent use, my LDL cholesterol dropped from 110 to 58! That's a huge win for heart health—I wasn't expecting that, but the psyllium fiber really does trap cholesterol and help lower it (backed by studies and Metamucil's own claims). No side effects for me, and it's affordable in bulk. If you have diarrhea/IBS-D issues or want natural cholesterol support, this is worth trying (start low and drink plenty of water).

Metamucil 4-in-1 Psyllium Husk GLP-1 Friendly Fiber Supplement, Sugar-Free, 180 teaspoons, Orange
Size: 2.3 Pound (Pack of 1), Style: Sugar Free 180 count
I started taking Metamucil after my doctor recommended boosting my daily fiber intake, and I genuinely wish I had started sooner. This sugar-free orange flavor has become a non-negotiable part of my morning routine. First, the taste — for a sugar-free supplement, it's surprisingly pleasant. The orange flavor is light and natural, not artificial or overpowering. Mixed into a glass of cold water, it goes down easily without that chalky, gritty aftertaste I dreaded from other fiber products I've tried in the past. The 4-in-1 benefits are the real selling point for me. I've noticed a genuine difference in my digestive regularity, I feel fuller between meals (which has helped me make better snack choices), and my energy levels feel more stable throughout the day. As someone on a GLP-1 medication, I was thrilled to find a fiber supplement specifically formulated to complement that — it fills a real gap in the market. The 180-teaspoon count is outstanding value. This container lasts a long time, which means fewer reorders and a lower cost per serving than most comparable products. The scoop is easy to use and the powder dissolves well with a quick stir — no clumping. My digestion has genuinely improved since making this a daily habit. Less bloating, more consistency, and I just feel better overall. It's one of those quiet little wellness wins that adds up over time. If you're on the fence, just try it. Simple, effective, great value — this is now a permanent fixture in my pantry. Cannot recommend it highly enough.

Does its job very well
Size: 2.3 Pound (Pack of 1), Style: Sugar Free 180 count
Been using Metamucil for years. Because it is a quality product that dissolves well in water, tastes fine, and a very easy way to stay regular. Considering what it does for my system, it is a cost efficient way to get more fiber in my diet with no side effects.
