PRODUCT: Red Vein Sumatra (Silver) Kratom Capsules


What is the OPMS “Silver” Product Line All About?

I’m back with another OPMS Kratom review! 

Previously, I tried the OPMS Green Maeng Da “Silver” capsules and really loved them. I’ve been dying to try the Red Vein Sumatra Kratom capsules – so let’s give it a go! 

OPMS Silver Capsules are a product line of Kratom capsules (various strains available) containing “1-time Kratom Extract”. They have an extensive cold water extraction process that is 100% natural – no harsh chemicals used. This process also includes lab-testing each and every batch for alkaline content to ensure quality and consistency. 

Geek Note: In general, Kratom Capsules are a great alternative to powder if you find yourself gagging on the harsh, bitter taste of Kratom. They’re also really convenient when traveling! 

Product Details: 

  • OPMS Silver Box is available in 9.6g, 19.2g, and 38.4g sizes.
  • OPMS Silver Bags are also offered in 16, 30, 60, 120, 240, and 480 ct.
  • 600mg per capsule
  • The capsule casing contains gelatin
  • Extracted from Red Vein Sumatra Kratom Powder
  • Mitragynine Content: 1.55% (9.3mg per capsule) 
  • 7-OH-Mitragynine content: 0.045% (<0.27mg per capsule)

Overall Product Quality

I really love the packaging. Each capsule is nested in a plastic casing (sort of how the old Eclipse Gum was packaged) that keeps them safe and intact. My box arrived with absolutely NO broken capsules! 

Right off the bat – I took 4 capsules. That dosage usually works really well for me. Since these contain powdered Kratom extract, I’d recommend starting off with a small serving for your first go around. 

The effects gradually became apparent about 45 minutes after consumption. I felt very relaxed, calm, and peaceful overall. I took them before eating lunch (around 11 AM), but I wished I would have waited until I got home because they were SUPER relaxing! I didn’t have any at the time, but I’m sure these would be great for relieving physical discomfort (backaches, sore muscles, etc). 


I purchase OPMS products from You can find their products elsewhere, too. To ensure that you’re buying authentic OPMS products, I recommend visiting their website and browsing through the list of certified vendors

Typically there are other size options available, but as I’m looking now (September 2022) they only have the 64 Capsules (38.8g) option. 

  • 64 Capsules (38.8 grams) = $12.95

The Final Verdict

I recommend OPMS Silver Kratom Capsules to anyone. Any strain – they all do the trick without having to take a ton of capsules at once. The price is hard to beat because of how effective the capsules themselves are. 

Again, please make sure that you are buying authentic O.P.M.S products. There are a lot of fake/counterfeit O.P.M.S products out there, so be careful and only buy from reputable vendors. 

For all you capsule lovers – I also highly recommend trying the Red Vein Sumatra Kratom capsules from Kratom Spot or Happy Hippo. Both are great! As you know, Happy Hippo Herbals is our favorite vendor here at Kratom Geek. You can use our Coupon Code GEEK20 to get 20% OFF your first order with them.
