About the Company

Spectrum Kratom started in 2017 as a brick-and-mortar herb store in Carlsbad, and from that moment on, it garnered a huge customer base. Unlike other vendors who offered various strains, this vendor focused on quality and simplicity.

Therefore, Spectrum Kratom only offers green, red, and white vein blends without the possibility of getting specific kratom strains. You won’t find exotic varieties or exuberant packaging here, but you will receive potent, high-quality kratom.

Interestingly, Spectrum Kratom offers customers the possibility of curbside pickup or delivery as one of its main features. Moreover, its online reviews are stellar, and its customers appreciate the care this vendor puts into its service.

Spectrum Kratom Product Reviews

This vendor is not characterized by quantity but rather by the quality of its products. It only offers white, red, and green-veined capsules, powder, and a unique FST Kratom Liquid Extract.

Product NameOur RatingPrice Range
Kratom Capsules4/5$18.99 – $109.99
Kratom Powder4/5$14.99 – $94.99
Kratom Extracts4/5$18.99 – $94.99

1. Kratom Powder

Kratom powder is the most popular and economical way to take kratom. You can add it to foods and drinks or simply use the toss n’ wash method to enjoy fast-acting effects at an affordable price.

Spectrum Kratom Powders are available in the following sizes and prices:

  • $14.99 per 30 g
  • $54.99 per 120 g
  • $94.99 per 240 g

Spectrum Kratom Green Vein Kratom Powder

According to Spectrum Kratom, its green vein kratom is the most potent strain it carries thanks to its high concentration of mitragynine and 7-hydroxymitragynine.

Depending on your dose, you can enjoy the full spectrum of kratom’s effects.

Spectrum Kratom Red Vein Kratom Powder

Spectrum Kratom’s red strain is ideal for relaxing after a long day or obtaining analgesic effects. The vendor blends the Red Bali, Red Hulu, and Red Kali varieties for this product.

We found this powder to be profoundly sedating, so you should start with small doses and gradually increase the amounts.

Spectrum Kratom White Vein Kratom Powder

White varieties are very sought-after by users looking for potent energy boosts or a replacement for their morning coffee. If you feel tired and need to face a hectic day, this strain is for you.

Be mindful of your doses when taking Spectrum Kratom’s white vein powder, as small amounts will be enough to energize you, while larger quantities may be too much to bear.

2. Kratom Capsules

Kratom capsules are an excellent alternative for those who want to enjoy the many benefits of kratom conveniently. The capsules are filled with powder to avoid the herb’s bitter taste.

Spectrum Kratom Capsules are available in the following sizes and prices:

  • $18.99 per 30 g
  • $69.99 per 120 g
  • $109.99 per 240 g

Spectrum Kratom Green Vein Kratom Capsules

Essentially, green-vein kratom capsules produce the same effects as the green powder but are more convenient to take. If you can’t stand the taste of kratom but still want to enjoy its wide range of effects, these capsules are a good choice.

Spectrum Kratom Red Vein Kratom Capsules

The red-vein kratom capsules will help you relax after an intense day, and taking a couple will help you fall asleep.

Thanks to their high content of 7-hydroxymitragynine, red varieties are characterized by their analgesic, relaxing, and pain-relieving effects.

Spectrum Kratom White Vein Kratom Capsules

Spectrum Kratom’s white-vein capsules are an excellent substitute for your morning coffee. Thanks to their compact size, they provide the ideal dose to boost your energy without being overwhelming.

3. Kratom Extracts

Kratom extracts are more concentrated forms of kratom. They can come in liquid or powdered form and typically retain a high alkaloid concentration, making them incredibly potent.

Spectrum Kratom FST Kratom Liquid Extract

We tried this product ourselves, and we found its peppermint flavor to perfectly mask kratom’s bitter taste, making the overall experience more enjoyable. This 15-ml full-spectrum kratom liquid extract is created using ethanol-based extractions for maximum potency.

This product’s prices:

  • $18.99 for each bottle
  • $54.99 per 4 bottles
  • $94.99 per 8 bottles

Is Spectrum Kratom Legit?

Yes, Spectrum Kratom is legit. This vendor is an AKA member and has complied with the Good Manufacturing Practices program since 2019. This means that its products are tested under strict quality standards.

Unfortunately, Spectrum Kratom does not provide its lab results to the public, although you can send them a message with your questions through their website.

Kratom leaf and flower.

Looking at its website for a few minutes, you can tell that this vendor loves kratom and does everything possible for the cause. On this site, you will find useful basic information about kratom and a blog section with tips and helpful advice.

Among its information sections is a handy map that summarizes kratom’s legality on a state-by-state basis. This is a handy resource considering the ever-changing and complicated kratom landscape in some states.

The company only offers three strains to simplify each customer’s experience. Spectrum Kratom uses eco-friendly and minimalist packaging to afford the testing process and the company’s superb overall service.

What You Can Expect To Pay

Spectrum Kratom’s prices are pretty high. While we understand that testing processes and general store maintenance are costly, we consider their prices too high.

For reference, you can find green vein kratom at Kona Kratom, one of the best online vendors, starting at $54.99 for 250 g. Meanwhile, 240 g of green vein kratom at Spectrum Kratom cost $94.99, almost twice as much.

This rather negative aspect of Spectrum Kratom makes it difficult to compete with other stores offering quality products but at a much lower price.

Accepted Payment Options

Spectrum Kratom’s payment options are standard, so you will have no problem buying its products. Unfortunately, this vendor does not yet offer the possibility to pay with Bitcoin, an increasingly used method in the kratom market.

These are the payment methods available at Spectrum Kratom:

  • E-Checks
  • Visa and MasterCard credit cards
  • Visa and MasterCard debit cards

Final Thoughts: Excellent Service, But High Prices

Spectrum Kratom is a Carlsbad-based store that offers a minimalist approach for customer convenience. This vendor offers only green, white, and red vein blends in powder, capsules, and liquid extracts.

You won’t find unique packaging or bizarre product names here. You will find an AKA-worthy vendor that sells high-quality, adequately tested products that comply with the best manufacturing practices in the industry.

Spectrum Kratom’s only downside is that its prices are too steep. Other more reputable stores with greater variety offer better value for your money, putting this vendor at a disadvantage.

On a positive note, this vendor offers free shipping and customer-friendly return policies. Moreover, many customers noted the friendliness and availability of the staff to solve their problems.

Overall, if you have the money, we recommend trying this store’s products. Still, if you want cheaper alternatives with a more extensive selection, we recommend checking out VIP Kratom, Kona Kratom, and Star Kratom.
