PhD Lean Degree Stimulant Free

PRODUCT REVIEW: PhD Lean Degree Stimulant Free Review.

This is an in-depth PhD Lean Degree Stimulant Free review.

Many fat burners have recently started to use stimulant-free formulas. Their goal? To provide you with the same (or even better) benefits of stimulants – but without the common side effects like anxiety and insomnia. So far, some have succeeded at it, while some haven’t.

PhD Lean Degree Stimulant Free, as the name suggests, belongs to the new generation of stimulant-free fat burners. It boasts a huge formula with 17 ingredients. It’s vegan-friendly and GMO-free. Great on the first glance, but once you look closer, you’ll notice some flaws. Ingredients with a lack of clinical evidence, potential side effects, and more…

But is it the right fat burner for you?

Pros and Cons

PhD Lean Degree Stimulant Free is made as an alternative to stimulant-based fat burners. It’s supposed to help you shred a lean physique but without any side effects. Sounds too good to be true? It might be. Their formula doesn’t look potent enough to provide any huge results.

Ingredients with fancy names aside, the lack of scientific evidence and side effects of certain compounds in this fat burner all point that Lean Degree may not be as good as some people hyped it up to be.

  • Chromium, cinnamon, and Jerusalem artichoke help stabilize your blood sugar
  • Phaseolus Vulgaris and Forskolin are good alternatives to stimulants like caffeine, although not as potent for fat loss
  • Vegan-friendly formula
  • Ineffective formula – too many ingredients with very little scientific evidence proving their effects on fat loss
  • Missing green tea extract, which is a key ingredient in fat burners
  • Doesn’t have any proven appetite suppressants
  • Hibiscus powder is known to be toxic at higher doses

Who Makes Lean Degree Stimulant Free

Lean Degree Stimulant Free is produced by PhD Nutrition. The company was established back in 2006 by two fitness enthusiasts from Yorkshire, England – Jason Rickaby and Mark Bowering. Since their humble beginnings, the company has grown and now sells products all around the world. PhD Nutrition prides themselves on their „innovation, great taste, honesty, and results-driven mentality.“

But can their stimulant-free fat burner, Lean Degree, give you the results you want?

Let’s find out!

PhD Lean Degree Stimulant Free isn’t clear on the benefits it offers. The site vaguely mentions how it contains vitamin B5 that helps reduce fatigue, as well as chromium that helps support blood sugar levels. And that’s about it.

This begs the question, are those the only benefits you’ll gain from this fat burner?


To answer the question of whether Lean Degree will help you lose weight, we should take a closer look at the ingredients. Let’s just say you’re in for a surprise.

As soon as you look ‘under the hood’, you’ll notice there are painfully many ingredients listed on the label. Many of them sound exotic but don’t have the evidence to back up their benefits.

This is supposed to be a stimulant-free formula that works just as well as its competitors with caffeine. But is this actually the case?

See for yourself:
Chromium Picolinate

Chromium is a trace mineral which helps your body metabolize certain macronutrients. It also helps regulate your blood glucose levels. (4)

Hibiscus Powder

Hibiscus powder is an ingredient thought to promote fat loss by blocking carbohydrate absorption, but studies still aren’t clear on this. What’s worse, Hibiscus is shown to be toxic at higher doses – PhD Lean Degree uses 500mg per serving. (1)

Acetyl L-Carnitine

Acetyl L-Carnitine is an antioxidant that can cross the blood-brain barrier. While it’s a great general health ingredient, it doesn’t help you cut fat according to science. Even its general health benefits are brought into question since PhD Lean Degree only contains 400mg per daily serving, and the optimal dosage is at least 630mg. (5)

Salvia Miltiorrhiza

Salvia Miltiorrhiza is an ancient Chinese herb that supports heart health. While it may be great for your cardiovascular system, this ingredient has no use when it comes to burning fat. (6)

Alpha Lipoic Acid

Alpha Lipoic Acid or simply ALA is shown to help diabetics with blood sugar control. Will it help you burn fat though? We’re afraid not.

Jerusalem Artichoke

Jerusalem artichoke is a root vegetable native to North America. It has a wide range of health benefits, from improved digestion to reduced inflammation. It contains inulin, a type of fiber that helps balance your blood sugar levels. (7) This can indirectly help with fat loss but the effects are relatively weak.


Tyrosine is an amino acid that helps your brain create more dopamine. This helps improve focus and cognitive performance under stress. For example, it can help you push a little harder in your workouts. No direct fat loss benefits though. (8)

Pomegranate Extract

There are many positive rumors surrounding Pomegranate and its health benefits. It’s thought to be excellent for reducing high blood pressure, improving recovery after exercise, and helping with chronic lung conditions. But according to WebMD, „there is no good scientific evidence to support these uses.“ (2)

Sesame Seed Oil

The sesame seed oil has a variety of benefits, but no, none of them are related to weight loss. It does have some weak effects on blood sugar, but the studies that tested this only examined the effects of this ingredient on diabetics. We don’t know if this ingredient has any effect on blood sugar levels of non-diabetic individuals.


L-Arabinose may improve metabolic health, but not metabolic speed. It seems like this is yet another ingredient in PhD Lean Degree that’s included just for show.

Top 3 Fat Burners That Actually Work

Phaseolus Vulgaris

We’re sure you’ll be as glad as we were when we saw this ingredient. Phaseolus Vulgaris or common bean is one of the only ingredients in PhD Lean Degree that actually has some decent scientific evidence confirming its fat loss benefits. While the effects aren’t huge, the studies were done on humans, not animals, which confirms its benefits for us.  (3)

Beta Sitosterol

If you’re a male, beta sitosterol can help improve your prostate health. It reduces inflammation and is shown to reduce the occurrence of benign prostatic hyperplasia. (9) You must be wondering what about the fat loss benefits – the answer is, there are none! Not that it’s surprising at this point anymore.

Coleus Forskohlii Extract

Coleus Forskohlii, or simply Forskolin, has many health benefits. You wouldn’t believe it, but one of them is in fact, fat loss. (10) It isn’t overly potent but it’s great to see it included here.

Cinnamon Extract

Cinnamon helps regulate your blood sugar after meals. However, PhD Lean Degree uses a cheap version of cinnamon which is known to put a strain on the liver. Especially since it’s concentrated in high amounts as an extract. Ceylon cinnamon would be a much safer option here. (11)

Phosphatidyl Serine

Phosphatidylserine (PS) is a phospholipid. Your brain cells are partially made from it. Taking it can help improve your mental performance. (12) This sounds awesome until you look at the dosage, which is only 24mg per daily serving. You need at least 100-200mg per day to experience any mental benefits. Not that it matters anyways since it isn’t a weight loss ingredient.

Pantothenic Acid

Pantothenic Acid or vitamin B5 helps reduce fatigue and tiredness. It can help fuel your workouts, indirectly helping with fat loss. But you’ll have to do a lot of work on your part for it to have any significant effect.

Dandelion Root

Dandelion works similarly to diuretics – it makes your body lose water. Don’t let this fool you though. Besides potentially making you dehydrated, dandelion won’t help you cut back fat. (13)

How to Take (Dosage)

On the producer’s website, they say you should take 2 capsules of Lean Degree, 3 times per day. This totals 6 capsules per day which isn’t a small number. You can take it with water or juice, ideally before each of your main meals. Also, you can safely take it close to bedtime as it has no stimulants that will keep you awake.

Side Effects

Since there are no stimulants in PhD Lean Degree, there’s a reduced risk of side effects. But there is one ingredient that raises concerns – Hibiscus powder. Some animal studies show that it’s toxic when taken in higher doses. Lean Degree boasts a hefty dose of Hibiscus; 500mg per serving.

Will it cause side effects in humans? No one really knows.


A 90-capsule bottle of Lean Degree will cost you £15.99 or $20. If you take 6 capsules per day as per recommendations, Lean Degree will only last you 15 days. Granted, it’s not an expensive product so you can always buy it in bulk. In fact, if you buy 2 bottles, you get free shipping and, only on certain occasions, 40% off the price.

Customer Reviews

Reviews on PhD Lean Degree are mixed.

One Amazon customer enthusiastically claimed: „Love the PhD line anyway but didn’t realise how good their fat burners are! Don’t leave you feeling tired afterwards and gives you no shaking overwhelming feelings but gives a good boost of energy!“

Other customers like Carol Dunnill claim that the product not only didn’t work for them but also produced side effects. Carol said: „I don’t seem to have lost any weight while taking these and they have been a bit harsh on my stomach making me feel unwell. Maybe they work for some people but not for me.“


So, is PhD Lean Degree Stimulant Free the right fat burner for you?

In truth, it’s a disappointing product. A lack of proven ingredients was the first red flag. The second red flag was Hibiscus powder which is essentially a toxin at higher doses.

We understand that PhD Lean Degree wanted this product to be an effective and safe alternative to stimulant-based fat burners. Did they succeed at it? Perhaps to a degree – there are a few ingredients that may help you lose weight.

With that said, we think there are better options out there, such as stimulant-free fat burners that are actually proven to work and have no side effects.
