Through our personal testing and market research, we’ve concluded that these are the best raspberry ketone supplements you can spend your money on.

But first, you may have a few questions about raspberry ketones and how they work.

What Are Raspberry Ketones and Do They Work for Weight Loss?

Without getting into too much advanced chemistry, ketones are natural substances (specifically natural phenolic compounds) found in raspberries and other fruits. They’re what gives raspberries their strong scent.

Raspberry ketones are used in cosmetics and as a flavoring in foods.

It would be logical to think that the raspberry ketones found in supplements would be extracted from raspberries, but that is actually not the case. It would take so many raspberries to produce just one dose of raspberry ketones for supplementation that it wouldn’t be financially feasible. As a result, the raspberry ketones you’ll find in supplements are actually synthetically produced.

Scientific interest in raspberry ketones began because researchers discovered that they were similar to synephrine and capsaicin. These are substances which are known to increase the metabolism. (1) (2)

From there, research done in animal subjects revealed these results:

  1. More of the hormone adiponectin was released. Adiponectin plays a role in regulating blood sugar levels and metabolism.
  2. It increased the breakdown of fat. (3)

There have also been a couple of studies done in rats that led to weight loss. (4) (5)

Now that we’ve covered a little on what raspberry ketones are and how they work, let’s get into what you came here for: the best raspberry ketone supplements on the market.

1. NatureWise Raspberry Ketones Plus+

NatureWise proudly claims that their Raspberry Ketones Plus+ supplement has been “doctor formulated with a rich blend of botanicals to help boost your metabolism, curb cravings and refresh your vitality”. At 400 mg of raspberry ketones, this product contains less of the active ingredient than other other products on this list, but it’s also infused with a very healthy proprietary antioxidant blend.

It consists of African mango extract, green tea leaves extract, acai berry powder, and cayenne pepper powder.

You might be wondering why NatureWise included these ingredients. Here’s a breakdown of what they do:

  • African Mango Extract: Research suggests it can aid in weight loss and lower blood and cholesterol levels
  • Green Tea Leaves Extract: The extract from green tea leaves is a source of caffeine and catechins. Both have been shown to increase thermogenesis, which assists in weight loss. (6) (7) (8) It’s also an antioxidant and has several other health benefits.
  • Acai Berry Powder: Acai is a Brazilian “superfood” known to have very high amounts of antioxidants. (9) They also could play a role in lowering cholesterol levels and have a positive effect on metabolism. (10) (11) (12)
  • Cayenne Pepper Powder: Cayenne pepper has been shown to increase feelings of fullness, helps burn fat, and boosts metabolism. (13) (14) (15)

That’s quite a few weight loss benefits in addition to the raspberry ketones.

NatureWise Raspberry Ketones Plus+ also comes with a feature that you won’t find in many other supplements. They have a mobile app called Transparency that you can use to scan your bottle and “unlock your product’s complete life story, from creation to delivery”. You’ll be able to see from where and how each ingredient was sourced and why it was included.

You won’t find any allergens, contaminants, binders or unnecessary fillers in this supplement. They’re made with vegetarian capsules.

NatureWise has a partnership with Vitamin Angels, which means your purchase makes a 1-for-1 donation to a mother or child in need. NatureWise is also environmentally responsible, so their product packaging is made using recycled materials.

Pros: 

  • Could increase metabolism
  • Could be effective at suppressing appetite
  • Has a proprietary antioxidant blend that provides weight loss benefits in addition to the raspberry ketones
  • Responsibly sourced and packaged
  • Only have to take one pill
  • Reasonably priced

Cons:

  • Has fewer raspberry ketones than other products on the market
  • It’s a blend so you don’t get just the raspberry ketones if that’s what you’re after

2. Purity Labs Raspberry Ketone Ultra

Purity Labs’ Raspberry Ketone Ultra supplement has quite a few similarities to our number one overall pick but didn’t make the top spot. We’ll get into why at the end of the section.

Much like the number one pick, this product is not just a raspberry ketones supplement—it contains 500 mg of raspberry ketones but also 300 mg of African mango and a proprietary formula made of green tea extract, caffeine anhydrous, apple cider vinegar, kelp, and grapefruit powder.

This proprietary blend is basically on par with what’s found in NatureWise Raspberry Ketones Plus+.

It’s made with a vegetable capsule and does not contain any dairy, soy, gluten, preservatives, or artificial colors.

It’s produced in a GMP compliant manufacturing facility.

It has a great 1-year guarantee: if for whatever reason you’re dissatisfied with the product within a year of purchasing, you can send back the bottle for a refund, no questions asked.

We saw great results from this product and so have a large number of consumers. The difference between Purity Labs Raspberry Ketone Ultra and NatureWise Raspberry Ketones Plus+ though is that they’re similar products but the NatureWise raspberry ketones are significantly cheaper.

Well, technically they’re right around the same price for a bottle. However, with the NatureWise raspberry ketones you only have to take one pill for a serving and you get a three month’s supply. With Purity Labs Raspberry Ketone Ultra, you have to take two pills for a serving and you only get a month’s worth.

Purity Labs Raspberry Ketone Ultra could work best for you though, as they have a slightly different proprietary formula.

Pros: 

  • Good active ingredients
  • Additional proprietary blend provides more ways to lose weight
  • Great return policy

Cons:

  • Is more expensive than other similar competing products

3. Fresh Healthcare Pure Raspberry Ketones

Fresh Healthcare’s Pure Raspberry Ketone is formulated to “shrink fat cells, and boost your metabolism”. They point out that the adiponectin that increases through the use of raspberry ketones that is “the machine that does the job”.

They claim that their product is naturally infused with free radical antioxidants that “not only help improve vitality levels, but help improve mood, energy, and a myriad of other benefits”. They also say that their raspberry ketones help with weight loss in another way: by being an appetite suppressant.

This product contains 1000mg of raspberry ketones, which is a fairly common dosage size for raspberry ketone supplements. There is no current recommended daily value for raspberry ketone.

These come in vegetable cellulose capsules, so they’re safe for vegans and vegetarians.

One bottle of this product has 180 capsules, which is a 90-day supply.

Pros: 

  • Could shrink fat cells
  • Could boost metabolism
  • Encourages increased secretion of the protein adiponectin
  • Great customer service

aSquared Nutrition notes that their product promotes healthy weight loss, is a strong source of antioxidants and works to shrink fat cells.

With aSquared, you get the peace of mind knowing that the product was made in an FDA-approved, cGMP-certified manufacturing facility in the USA.

This product features a natural formulation that contains no binders, preservatives, GMOs, or unnecessary fillers. That’s always a good thing, as these ingredients can lead to all sorts of bad side effects.

Just like Fresh Healthcare’s Pure Raspberry Ketones, aSquared Nutrition’s supplement contains 180 capsules, which makes for a 90-day supply at 2 capsules per day. While this is a pretty affordable product (a yearly supply would be just under $100), it’s very similar to our number 1 pick but at a higher price point.

Pros: 

  • Promotes weight loss in a variety of ways
  • Provide a potent dose of raspberry ketones
  • Multiple consumers report it helps keep them regular

Cons:

  • Some say it causes a jittery feeling

TigerEye Raspberry Ketones is another high potency (1000mg) raspberry ketone supplement to choose from.

We included it in our list because of its simplicity. Sometimes you’re just looking for a supplement with one active ingredient and nothing else.

Additional ingredients might be ineffective for you personally or you may have an adverse reaction to them. There are plenty of reasons why you may want just a single active ingredient in a supplement and nothing else.

Regardless of the reason, TigerEye Raspberry Ketones does just that: it’s 1000mg of raspberry ketones, a vegetable cellulose capsule, and that’s about it.

The raspberry ketones in this supplement could provide the metabolism-boosting and appetite-suppressing benefits that the substance is known for.

There is no wheat, gluten, yeast, sugar, corn or preservatives in this supplement.
