Hydroxy Lean

Updated May 17, 2019.
Published Feb 2, 2016.

Hydroxy Lean is often confused with another product called Hydroxylean with Ephedra. The ephedra-based product is dangerous and is banned in various countries, whereas this product is a standard, powder-based metabolic supplement. Hydroxy Lean seems to work better as a muscle-building product than it does for weight-loss. There is an excellent money-back guarantee on Hydroxy Lean, but it works out to be an expensive supplement as a tub only lasts for 15 days when you take the recommended amount.

  • No customer reviews

Hydroxy Lean
Whilst many of the weight loss supplement we look at are capsules or tablets, others are powder based, to be mixed with water and drunk. This allows for higher doses of some ingredients without the need to take an inconvenient number of capsules each day. Hydroxy Lean is a powder-based supplement designed to promote fat burning and weight loss.

Below, we take an in-depth look to see how effective Hydroxy Lean really is.

Hydroxy Lean Overview

What you need to know about Hydroxy Lean

With no customer reviews available, it is very difficult to establish whether Hydroxy Lean works well in practice to aid weight loss and prevent loss of muscle mass when dieting.

The ingredient quantities used in the product are generally very good, but the amounts of green tea are less than adequate. L-carnitine is not a good fat burner for most of the population, but is useful for consumers who are trying to gain muscle mass. Similarly, many of the ingredients are amino acids and other ingredients that will either maximise muscle gains when exercising to increase muscle mass, or help to prevent muscle loss when on a calorie restricted diet plan.

Caffeine and green tea are the only two ingredients that will directly help to promote weight loss. Whilst both are considered to be effective and reliable weight loss aids, they are also not hugely effective, and so may only increase the consumer’s weight loss by a small amount.

What are the side effects of Hydroxy Lean?

Hydroxy Lean contains some stimulant ingredients that may cause side effects. For a full list, please see the Side Effects section below.

How much does Hydroxy Lean cost?

A tub of Hydroxy Lean costs AUS $59.95, plus delivery charges. This will only last for 15 days if you take the recommended amount.

Hydroxy Lean Key Features

Hydroxy Lean is a fat burning weight loss supplement that increases the metabolism and suppresses the appetite, according to the manufacturers. It also contains ingredients that should help to preserve lean muscle mass whilst the consumer is losing weight, leading to a leaner build. It is manufactured by Genetix Nutrition. However, there is very little information available about Genetix Nutrition. They provide no contact information other than facebook page and a contact us box on their official website.

Hydroxy Lean Key Points

  • Manufactured by Genetix Nutrition.
  • 30 servings per tub.
  • May aid muscle building.

There is a similarly named product available from a different supplement company, called Hydroxylean with Ephedra. It is important that consumers do not confuse these two products, as they contain very different ingredients; Hydroxylean with Ephedra may also be banned in some countries because of its Ephedra content, and could be confiscated at customs.

How to Take Hydroxy Lean

Stir one tablespoon in cold water and mix. Best when taken 30 minutes prior to breakfast and or lunch.

Hydroxy Lean comes in watermelon crush flavour.

Hydroxy Lean Concerns:

  • No customer reviews.
  • Only available in Australia.
  • Only provides 15-day supply.

What does Hydroxy Lean claim to do?

The manufacturers describe Hydroxy Lean as follows:

Hydroxy Lean contains therapeutic doses of herbal extracts than can assist in breaking down stored fat, suppressing appetite and increasing your metabolic rate.

Hydroxy Lean contains impressive fat burning amino acid Acetyl Carnitine in conjunction with a combination of high strength metabolism boosters such as Green Tea Extract and lean muscle builders such as Alpha Lipoic Acid. The specific blend of ingredients found in Hydroxy lean ensure whilst calories are burnt at a fantastic rate, that lean muscle is maintained. This is where other potent fat burners fail. Hydroxy Lean takes fat burning to the next level and the result will be a physique you can be extremely proud of.

Does Hydroxy Lean work?

L-carnitine can reduce body fat, but this is primarily seen in the elderly, and so the claims made by the manufacturer that Acetyl L-Carnitine is an ‘impressive fat burning amino acid’ are misleading. However, L-Carnitine is most beneficial for individuals who exercise regularly and who are trying to build strength and muscle. It reduces fatigue after strenuous exercise, and also helps to speed up recovery from exercise, with studies showing less muscle damage, including less muscle soreness, when taking L-carnitine than the exerciser would feel without supplementation.

The catechins found in green tea increase thermogenesis in the body, and caffeine found in both guarana and green tea will slightly increase the metabolism. These will both lead to more calories being burnt throughout the day, but the effects of both caffeine and green tea are considered to be small but significant.

Hydroxy Lean Ingredients

The ingredient quantities and nutritional information provided below is per 12 gram serving dissolved in water.

  • L-Arginine Alpha-Ketoglutarate 2 grams: This essential amino acid is plentiful in foods and can be made by the body. It is important for wound healing and circulation, and so could be potentially useful for regular gym-goers.
  • Leucine2 grams: An essential branched-chain amino acid which stimulates protein synthesis in the body, and is used as a building block for muscle. Whilst dieting, supplementing Leucine could help to maintain muscle mass whilst still losing fat mass, as it is used to help fuel muscle.
  • Acetyl-L-Carnitine2 grams: There is some evidence that supplementation of acetyl-l-carnitine can reduce body fat, although the strongest results were seen in the elderly. The ingredient also boosts energy levels, and is used to treat fatigue.
  • Acetyl Tyrosine 1 gram: Some people use Tyrosine as an appetite suppressant, but there is little clinical evidence that it is effective for this use. Large doses of tyrosine may be useful for increasing alertness, especially in people who are sleep deprived.
  • Taurine 1.5 grams: Used often in energy drinks, some studies suggest that this amino acid may play a role in athletic performance, meaning that it is only useful for dieters who exercise. There is no link between Taurine and weight loss known at this time.
  • Phenylalanine 1 gram: An amino acid which is used for treating depression, amongst other things. However, the research to suggest that this will effectively treat depression is outdated, with calls for more testing using updated research methods.
  • Guarana 400 mg: A berry that is naturally high in caffeine, it is often an ingredient in energy drinks and diet pills. Numerous studies have shown that caffeine boosts energy levels and alertness, as well as mildly boosting the metabolism. The effects shown in studies are small, and some studies are inconclusive.
  • Green Tea Extract 120 mg: Green tea is high in a group of antioxidants called catechins. Studies have suggested that catechins increase thermogenesis in the body, whilst caffeine increases energy expenditure by boosting the metabolism slightly for few hours.
  • Alpha Lipoic Acid 50 mg: Appears to suppress the appetite by inhibiting AMPK in the hypothalamus although little research has been conducted in humans at this point. This fatty acid also appears to boost fat burning slightly, although the effects are not as large as the noted suppression of appetite.
  • Niacin 100 mg: Vitamin B3, or Niacin, is responsible for helping to produce energy from consumed food, as well as helping keep the nervous and digestive systems healthy. Niacin can be easily sourced in adequate amounts from a balanced diet. Persistent excessive consumption of niacin has been linked with increased rates of obesity in American Children. The RDA for adult males is 16 mg, and so this dose is definitely excessive.

Hydroxy Lean Side Effects

There are several ingredients used in Hydroxy Lean that could cause a variety of side effects.

Side effects of caffeine can include headaches, increased heart rate, increased blood pressure, heart palpitations, increased urination, dehydration, jitteriness, dizziness and insomnia. Green tea can also cause constipation.

Side effects of acetyl-l-carnitine include stomach upset, nausea, vomiting, and restlessness. It can cause a “fishy” odour of the urine, breath, and sweat, especially when consumed in large quantities.


Not suitable for anyone who is pregnant or breastfeeding. Not suitable for anyone under the age of 18. Not suitable for anyone who is sensitive to stimulants including caffeine, or anyone who has any heart related health issues, including but not limited to high blood pressure. Phenylketonurics: Contains phenylalanine.

Where To Buy Hydroxy Lean

Hydroxy Lean is manufactured by Genetix Nutrition, but it is not available directly from their website. Hydroxy Lean is sold by Nutrition Warehouse, an Australian online retailer. A single tub costs AUS $59.95, plus delivery charges. Delivery is free on orders of $150 or more, and costs AUS$9.95 for smaller orders. Shipping insurance is also available.

Each tub contains 30 servings, and if used twice a day, will provide a 15-day supply.

Watchdog Verdict

Hydroxy Lean appears to be a product best used when trying to gain muscle as well as lose some fat mass, specifically by undertaking muscle building exercises. Consumers who are not exercising will not see very much benefit from Hydroxy Lean.

The product is covered by an excellent returns policy, with a 60 day period to return unopened products and 30 days for opened products. However, Hydroxy Lean is only available within Australia at present, and we could only locate one supplier for the product, meaning that there is no price competition or ability to shop around for a good deal.

There is very little information available about the manufacturer of Hydroxy Lean at all. There is also no customer feedback in the form of customer reviews for the product. This makes it difficult to establish how likely side effects are, or how well the product works in practice.

Unlike capsule supplements, powder supplements such as Hydroxy Lean are not very practical or easy transportable; this is especially true as the product should be taken at both breakfast and lunch, and so consumers may need to take the bottle around with them in the day, for example, to work with them.

Overall, we do not recommend Hydroxy Lean to our readers as it will not aid very much weight loss, and a single tub does not last for very long at all.
