This is going to be a relatively short Optiburn Amped review, we generally don’t rate powdered “fat burner” supplements very highly seeing as they have to miss out on some of the most effective ingredients like glucomannan as they need to be ingested in capsule form.
Optiburn is more of a pre workout with a diuretic than a fat burner. Although ironically it is a better than Optiburn Fat Burner, which is basically the same supplement without the stimulants.
There isn’t actually a single ingredient in Optiburn that’s well backed by research to suggest it would assist with weight loss in any substantial way beyond caffeine. Most of the ingredients in Optiburn are fine for a pre workout, they’ll help give you energy and so on, but it won’t do you any more good than any other pre workout. Aside from the fact that it will make you pee more, so you could weigh less theoretically.
The fact is this is a recent marketing trend of slapping weight loss or fat burner on entirely unrelated products, with probiotics doing this a lot recently as well. If you’re looking for a supplement that’s actually designed to help you lose weight whilst training, we’d recommend instant knockout, it has everything in Optiburn that works, and a host of other useful ingredients such as the aforementioned glucomannan.
couldn’t find any that we could verify as real purchases, we found reviews for a few different Optiburn products on some sites that sell the product, but these were curated comments. Which means site owners often delete negative reviews as they want to sell more products.
That said, most of which were complementary about the taste, but none of them said much if anything about the products weight loss effects.
The only other reviews that we could find were on supplement review websites which both promote the product and curate the reviews manually. These were all positive however.
But, we couldn't find any third party none curated reviews such as trustpilot or amazon.
We answer some of the most commonly asked questions that came up when researching our Optiburn Amped Review.
The label says to take 1 scoop of optiburn amped in the morning before your first meal, but realistically we’d suggest it’s probably better to take it about 30 minutes to an hour before working out, there’s a fair amount of caffeine in it, so there is the fact that it would be good for waking you up first thing in the morning. Taking it with some food however may be advisable to avoid an upset stomach.
Optiburn amped doesn’t really have much going for it in terms of weight loss ingredients. It misses Glucomannan (one of the most effective over the counter appetite suppressants ) and doesn’t really add anything to replace this, what it does have is a high dose of caffeine and other energy boosters.
Conjugated linoleic acid– Initial showed that CLA helped women who did no exercise lose 9% of their body fat, but these were quite quickly debunked and the ingredient quite commonly caused nausea. But worse, it actually seemed to have caused negative weight loss effects as a result of it’s negative effects on glucose metabolization. 
L-carnitine – Once again we’ve got another energy booster, Acetyl-L-carnitine helps the body produce energy. It’s important for brain and muscle function, but any weight loss would come from energy boosting, again this would be a great ingredient for a pre workout, not for a fat burner, which optiburn claims to be.
Lotus Leaf – There are some rat studies which suggest that lotus leaf is effective at aiding weight loss , but unfortunately nothing currently to suggest it’s effective in humans. Lots of ingredients that have initially looked good in animal trials have shown no impact in humans, like raspberry ketones which is also in Optiburn Amped.
Green Tea – Some research suggests that catechins in green tea help improve fat oxidization helping burning fat more effectively, this is a relatively minimal effect however. As such it’s usually the least important ingredient in the better fat burners.
L-Taurine – Taurine has studies backing it in terms of an energy booster , so it could help your work out harder, but it by itself will not help you lose weight. It is included in a lot of energy drinks for this reason.
African Mango (Irvingia gabonensis) – The only studies that back this ingredient were sponsored by people who make supplements that include african mango. There are no independent studies that show it’s effective at aiding weight loss, not a great inclusion for Optiburn Amped.
Horse Tail Extract – There’s not a whole lot of evidence to support this one either, some animal studies here and there, but nothing much for humans.
Caffeine – Caffeine is doing the heavy lifting here. It works in two ways, it helps you move more, something that we do less when we’re on calorie restricted diets, and it has a mild thermogenic effect. This ingredient is doing the heavy lifting and caffeine pills are pretty cheap. But Caffeine is effective for assisting weight loss. 
Green Coffee Extract – Green Coffee Extract does help with weight loss, it has a mild thermogenic effect (but we’re talking double digit calories per day, so nothing substantial.
Rasberry Ketones – This ingredient looked promising in a few animal studies, but has since been completely debunked in human trials.
Dandelion – Dandelion extract is a diuretic so you’ll pee more, which could make you seem to lose some water weight, but this will only work for the first few days of taking the supplement.
Higenamine – This is a stimulant similar to caffeine.
Synephrine – This can increase fat oxidization giving you more energy whilst working out.
With Optiburn being so heavy on stimulants, it has some minimal appetite suppression, but nothing like what you'd get from a dedicated appetite suppressant.
Optiburn amped isn’t a fat burner, at least not in anything other than name. If we’re reviewing it as a pre workout, it’s not bad. If we’re looking at it in terms of what it claims to be then, it fails miserably, not stacking up to well against anything that’s actually a dedicated fat burner.
We don’t recommend Optiburn as a weight loss assistant, however if you’re already on a calorie controlled diet then it could have some benefit in helping keep you energized as we tend to move less when we’re restricting calories meaning we burn a bit less through the day.
But if you’re looking for something to actually help you lose weight and you’re happy with high caffeine levels, then take instant knockout instead. If you’re looking for an energy booster powder, then sure, Optiburn is fine, but seeing as their marketing focuses on weight loss, we find the product misleading.
