REVIEW:Veganicity Xtra Slim

By Pete Ryan

Xtra slim is a fat loss product based on several herbal and supplementary products reputed to cause fatloss.

The main ingredients are:

  • Green tea
  • Guarana
  • Ginger
  • Acia
  • Caffeine
  • Carnitine

We can go through these and find out whether this is the right supplement for you and if it is likely to work.

Green tea

Green tea has been shown in several studies to aid in fat loss[i]. Unfortunately, you would need an infeasibly high intake of tea to get any fat loss, so supplements seem the only way to get enough to have an effect.


Guarana is a seed. It has more caffeine that than the coffee bean, and it has been used for fat loss for a while now.  Research suggests that it may help in a little fat loss[ii]. It has a load of antioxidants and phytonutrients for the body as a side benefit.


Ginger can control your cholesterol[iii].  It is also a great antioxidant and has anticancer properties.


Acai is a fruit. It has been hyped way beyond any supplement can live up to.  However it does have some fat loss abilities[iv]


Does this need any introduction? Caffeine pumps up metabolism and increases alertness.[v] Remember that caffeine can be addictive, so be aware of cycling off periodically.


This can raise alarm bells for a few people. Carnitine is very high in meat, specifically red meat and recently it has been suggested in research that  ingested carnitine turns into TMAO, which in turn causes atherosclerosis to occur (we are talking blocking arteries here!).  This would be a concern...if you were a meat eater...however studies have shown that vegans have the right bacteria in the gut, the type that do not turn carnitine into TMAO and so if vegans take carnitine it does not cause any issues[vi].

So, with that settled this supplement is not a concern for vegans we’ll get down to the actual product.


The supplement is a stimulant. It is probably not a good idea to take it late in the evening.  It can help you get work done and will get both the mind and body moving.  I actually used it as a replacement for a pre-workout to good effect.  If you are currently using (or wish to try) a stimulant-based pre-workout, then this is actually something I would consider, especially if you are after the twin goals of training stimulation and fat-loss.

My recommendation is something like 4-8 weeks on, then 4 weeks off (avoid caffeine as much as possible during the ‘off’ phase).

This product will not carve away large chunks of fat.  It could however help you shift that last bit of belly fat or increase losses of fat slightly during a cut.

If you are cutting and just need a little support to help suppress the appetite slightly and increase the activity level a little, then this might be just the thing.
