Enhanced Weight Loss

Hydroxycut Hardcore is supposed to be able to double your weight loss efforts compared to a standard diet and exercise alone. This is due to many ingredients, but they particularly focus on green coffee extract. 

Elevated Energy and Intensity

With a high dose of caffeine and added theanine, Hydroxycut Hardcore is designed to increase your energy levels and help increase the intensity of your workouts. 

Boosted Thermogenesis

Third, Hydroxycut Hardcore claims to have a number of so-called thermogenic ingredients, such as green coffee extract and cayenne pepper, to help you shred off fat and get a leaner physique. 

Hydroxycut is America’s #1 selling weight loss supplement brand, but can this Hydroxycut Hardcore supplement truly deliver potent weight loss? Read on to find out!

Hydroxycut Hardcore Ingredients

Hydroxycut Hardcore comes in capsule form, and the serving size is 2 capsules. Here’s the breakdown of what’s in this product, as indicated by the label:

  • Pyroxyclene Anhydranine Blend (368mg)
    • Caffeine Anhydrous
    • L-Theanine
    • Cayenne Pepper
  • Yohimbacore Robusta Blend (250mg)
    • Green Coffee Extract
    • Yohimbe Extract
  • 1, 3 D-Norepidrol Blend (128mg)
    • L-Tyrosine
    • L-Methionine
    • L-Leucine
    • Trans-Ferulic Acid

So, it’s essentially a combination of three key blends, each with their own ingredients.

Pyroxyclene Anhydranine Blend

The first blend is the Pyroxyclene Anhydranine Blend, which is a trademarked blend that includes caffeine anhydrous, l-theanine, and cayenne pepper. 


Caffeine increases norepinephrine and has stimulating effects, which can ultimately increase metabolic rate and thermogenesis, which is why it can help with fat loss. The recommended dose is 200 to 400mg. 


L-theanine is an amino acid found in green tea. It doesn’t really have any effects on weight loss, although it can provide a calm focus when paired with caffeine. 

Cayenne Pepper

Lastly, cayenne pepper contains capsaicin, which has been shown to have stimulating effects on the body and increase thermogenesis. Plus, capsaicin can help regulate blood pressure, lipids, and glucose, all of which play a role in weight management. 

Yohimbacore Robusta Blend

The next blend is the Yohimbacore Robusta Blend, which consists of green coffee extract and Yohimbe extract. 

Green Coffee Extract

Green coffee extract is an extract from raw coffee beans, which has a high presence of chlorogenic acids. The overall research shows that green coffee extract supplementation modestly benefits weight loss, usually leading to a few more pounds lost over several weeks compared to placebo. 

Recommended dose is 300 to 600mg. 

Yohimbe Extract

Yohimbe extract has a compound in it called yohimbine, which acts as an alpha-2 adrenergic receptor antagonist. This allows more adrenaline to stay in your body for longer and helps the body burn fat for energy. But the overall research is mixed on whether or not Yohimbe actually works. 

Recommended dose is 15 to 30mg. 

1,3 D-Norepidrol Blend

The final blend in Hydroxycut Hardcore is 1,3 D-Norepidrol Blend, which consists of l-tyrosine, l-methionine, l-leucine, and trans-ferulic acid. 


Tyrosine is a precursor to dopamine, epinephrine, and norepinephrine, so in theory, it could provide stimulating effects that help with weight loss, although there’s not much good evidence. But it can help with cognitive function when under stress. 


Methionine is an important amino acid, but it doesn’t appear to have any benefit for fat loss; in fact, sometimes decreasing methionine intake helps fat loss. 


Leucine is important for protein synthesis and plays a role in glucose and insulin function, both of which may make it easier to maintain muscle mass when dieting. 

Trans-Ferulic Acid

Finally, trans-ferulic acid is a phenolic acid that has been shown to have antioxidant and anti-inflammatory effects, while also promoting healthier levels of glucose and lipids. Yet, no human research has shown its effects for weight loss. 

Does Hydroxycut Hardcore Work?

Overall, Hydroxycut Hardcore should aid weight loss, but there’s nothing spectacular about it.

The main beneficial ingredients are caffeine, cayenne pepper, and green coffee extract, all of which can help increase metabolic rate and thermogenesis, which likely will help you lose some fat. 

But the other ingredients really don’t have enough research proving that they will help people lose weight and shred off body fat. 

Claims vs. Reality

Hydroxycut claims that Hardcore will help you double your weight loss efforts compared to a traditional diet and exercise alone. But if we look closely, the main ingredients in Hydroxycut Hardcore will likely only help you lose an additional 3 to 7 pounds or so over a period of several weeks. 

This isn’t insignificant, and that might be all the boost you need. Just be aware that it likely won’t be anything extraordinary. 

You should also get a boost in energy and focus from caffeine, theanine, and tyrosine, and this could help you get through your workouts too. 

Overall, Hydroxycut Hardcore has mild benefits for weight loss and fat reduction. 

Who is Hydroxycut Hardcore Best For?

Hydroxycut Hardcore is best for anyone who is already on a calorie-restricted diet and exercise program and wants to try to maximize their fat loss. And, of course, you have to be okay with taking in a lot of stimulants (this is definitely a no-go for the stimulant sensitive).

Is Hydroxycut Hardcore Safe?

There are definitely some possible side effects that you need to be aware of. Mainly:

  • Increased heart rate and blood pressure (plus, yohimbine sometimes leads to arrhythmias)
  • Elevated anxiety, jitters, nervousness, and insomnia
  • Headache and dizziness
  • Nausea, upset stomach, and other digestive symptoms

The chance for side effects increases as you up the dosage. So, if you take 4 capsules (which they recommend after the initial tolerance period), you may have more side effects than if you just take two; something to consider. 

Also, Hydroxycut Hardcore is made in the USA with international ingredients.

There are 30 servings (60 capsules) per bottle of Hydroxycut Hardcore for a price of $22.99. 

They recommend you take 1 capsule the first day, 2 capsules on days 2 and 3, and 2 capsules twice per day from there on out. But individual tolerance will dictate your dosage. 

So, you’ll pay $0.77 to $1.53 per day, depending on how many capsules you take (anywhere from 2 to 4). Overall, this is a pretty affordable price, especially if you only need two capsules.
