Avesil 

Avesil is average.

If you wanted to find one of the most generic and boring weight loss supplements on the market, this is likely to be a front-runner.

Avesil's marketing says all the usual stuff; it’ll reduce appetite, boost energy levels and assist with weight loss. It doesn’t get less specific than that.

As the nutritional supplement industry continues to swell, consumers are looking for something new – a product with some scientific innovation, or at least some flashy packaging. Avesil offers neither.

What is Avesil?

Avesil's average start does not stop the product from making some big, flashy claims. The official Avesil website states that the product is capable of helping users achieve “three times” the amount of weight loss that would otherwise have taken place using diet and exercise alone.

For such a boring, run-of-the-mill supplement, this is a bold move, and one that we doubt is backed up with science and real-life results.

The supplement also gives consumers a guarantee that they will experience weight loss, improved energy levels, and appetite control. Despite the use of the phrase ‘guarantee', there’s no mention of compensation if these results are not seen.

Avesil's website and choice of marketing imager are as generic as the supplement itself: a fit girl drinking water. This is a classic attempt to utilize mind association – “This could be you!”.

The alarm bell really begins to sound when we take a look little further down Avesil's home page. Avesil is offered to consumers – in big, bold letters – on a “Trial” basis. This is a deceptive move that is incredibly common within the nutritional supplement industry. The use of this particular play has reduced substantially following the Federal Trade Commission (FTC) outlawing this style of marketing in 2015. While it is likely that the language used on the Avesil website has been selected carefully to ensure its legality (“trial” rather than “free trial”), it can still not be considered morally correct to trick people into making purchases in this way.

The company responsible for Avesil is one thing that does stand out about this product – not for the correct reasons, unfortunately. The manufacturer of Avesil is notably very difficult to track down and is not accredited by the BBB (Better Business Bureau). There isn’t much more to say on the matter considering the lack of information available.

Does it Avesil work?

The basis of Avesil as a weight loss supplement is that it is a thermogenic diet pill. These types of supplements often describe themselves as “fat-burners”. The idea is that, by increasing the amount of energy converted into body heat, your body will be triggered to burn increased levels of stored energy i.e. fat.

The science behind this theory is sound and thermogenic supplements do exhibit measurable effects on the body's basal metabolic rate, but obviously, each supplement's success comes down to its own specific list of ingredients.

Ingredients:

  • Decaffeinated green tea: Green tea and green tea extract are ingredients frequently listed and utilized by a broad range of dietary and weight loss supplements [1]. Green tea is rich in antioxidants and has been shown to exert a slight increase in metabolism on supplementation at a high enough dose [2,3,4]. The issue with the green tea contained in Avesil, however, is that it is decaffeinated. While it is likely that the Avesil design team believed they were doing consumers a favor by removing the caffeine from this ingredient, what the removal of caffeine has really done in this instance is render green tea more or less useless on the weight loss front [5,6].
    The impact on metabolism that is usually seen in sufficient doses comes down to the green tea's caffeine content. Removing this caffeine removes the metabolic effect. While green tea does still contain high concentrations of antioxidants, yet again removing the caffeine is detrimental, as the caffeine compound itself contains many of the antioxidants usually found in green tea's chemical profile [7].
  • Meratrim: This is interesting; Meratrim is actually a supplement in its own right, yet it is officially listed as an Avesil ingredient. Meratrim's ingredients include microcrystalline cellulose, silica, rice bran and the ‘effective natural weight loss’ ingredients, Garcinia Mangostana and Sphaeranthus. Garcinia Mangostana and Sphaeranthus are both traditionally used in medicines from Asia that date back centuries. It is safe to say that both these compounds would have to be consumed in large quantities to exhibit any noticeable impact [8].
    Studies on this supplement seem to conclude that it works ‘in conjunction with diet”. It is likely that the claims that the formula increases lipolysis are actually inaccurate, and any weight loss that was seen by consumers is down to a change in lifestyle rather than Meratrim. Always be skeptical when you see Garcinia [9] on the ingredients list.
  • Chromium Chromate: Chromium in a mineral micronutrient that is needed by our body in small amounts. Chromium plays an essential part in the metabolic processes that are required to maintain proper regulation of blood sugar, and maintenance of insulin efficacy (i.e. it helps to prevent the build-up of insulin resistance) [10].
    These impacts do seem useful but it has been concluded that Chromium supplementation is only of any use in two distinct populations [11]: Those who are chromium deficient [10] and diabetics [10].
  • Natural caffeine USP: Here’s where things start to get a bit… odd.  Recall how the manufacturers of Avesil have chosen to have the caffeine removed from the green tea that is included in the product. Their logic seems to make some sense, even if they hadn’t fully thought through all the implications of removing this caffeine. What doesn’t make sense is that one of the other main ingredients in Avesil is Natural Caffeine USP. This is pure natural caffeine extracted from coffee beans with a high-quality grade (known as the USP grade). The caffeine is included in this supplement for its metabolic impacts and lipolytic activity [12,13,14], but its inclusion makes us question if the use of decaffeinated green tea is of any use whatsoever? Out of 87 customer reviews on Amazon.com, 50% give the product only 1 or 2 stars. Most of these reviews comment on how the product is too expensive and does not work.

While it is true that each of the ingredients in this supplement has been clinically tested individually, and each has been individually linked to weight loss, insulin control and/or increased metabolic rate, incorporating them all into one pill does not make for an effective product. It is likely that the concentrations of each ingredient are nowhere near the high concentrations required to make a notable impact on humans.

Practicalities and Market Alternatives

A 30-day supply of Avesil is priced at $89.95 – a hefty price to pay for a pill that does next to nothing.

Even if you were to decide to risk your cash on this supplement, you might struggle to find the product at all. Avesil is currently very difficult to locate for purchase online or in stores.

On a positive note, there’s not much to report on Avesil when it comes to side effects. Those individuals who are highly stimulant sensitive might experience mild “over-caffeinated-type” side effects such as jitteriness, increase heart rate or mild gastric disturbance, but these prove to be trivial complaints.

Closing Remarks

It must be said that, for all its downsides, Avesil does contain a set of clinically tested and proven ingredients. This ingredient list also boasts an ‘all-natural’ status which is always a pleasure to see.

But, despite the scientific backing of its individual components, Avesil itself remains largely ineffective as a weight loss supplement due to insufficient quantities of these active ingredients.

If you’d like to try out a weight loss supplement, our suggestion would be to keep searching and try and find one that has turned out successful test results as a whole product.
