Advocare Spark is relatively low in calories compared to G Fuel. See the difference in this table:

This makes Advocare Spark a highly preferable energy drink to have if you are on a low-calorie diet. In these diets, a ten-gram calorie gap is considerably big

Advocare Spark positions itself as a vitamin supplement but has the ingredients of an energy drink. Its calorie count is also great for people on weight control if you’re not as strict.

As you may know, the calories that you were not able to burn will turn into stored fats and when accumulated lead to weight gain.

However, you can benefit more from G Fuel as it can provide more energy in terms of calories. You would want this if your daily activities often require a lot of physical energy like traveling and working out.


In carbohydrates, G Fuel is still leading against Advocare Spark, but this time the difference is very close. Check this table:

Carbohydrates number comparison between G Fuel and Advocare Spark.

In my opinion, a difference of as little as 1 carb shouldn’t affect your diet. Besides, whichever energy drink you pick, you get low counts of carbohydrates.

Therefore, both G Fuel and Advocare Spark can be good supports if you’re trying to lose weight and can provide you similar energy with carbohydrates as fuel.

Sugar G Fuel vs Advocare Spark

G Fuel and Advocare Spark don’t contain any sugar.

Clearly, there’s no competition on which is a better energy drink in terms of sugar content because both are sugar-free.

Not only that, eliminating sugar from your diet promotes improved energy levels, a sharp brain, clear skin, and healthy teeth.

Comparison of Caffeine

G Fuel has stronger caffeine content compared to Advocare Spark.

Caffeine is a star ingredient in energy drinks.

Comparison of caffeine level between G Fuel and Advocare Spark.

How much caffeine your energy drink has is crucial in how long you can last during a certain activity.

Caffeine is a psychoactive drug that enhances your cognitive functions and boosts your energy. Having said that, the higher caffeine intake the better energy, focus, and endurance you’ll have.

However, that’s not always the result you’ll get. Too much consumption of caffeine can lead to side effects such as nervousness, palpitation, and insomnia.

Note that G Fuel and Advocare Spark’s caffeine level is comparably high than your regular cup of coffee, which is 80-100mg. But for an energy drink, these caffeine contents fall under the average category.

So which one should you pick, G Fuel or Advocare Spark?

I think G Fuel is the better choice for a frequent caffeine consumer who has high caffeine tolerance, looking into fueling their body with energy, endurance, and mental functions.

Although, Advocare Spark can also provide the same needs. The only difference is how tough the caffeine kick can get, and how capable your body is in handling it.

Ingredients G Fuel vs. Advocare Spark

Now, let’s go ahead and compare the rest of the nutrients found in G Fuel and Advocare Spark and find out who offers a better set of ingredients.


In terms of vitamins, Advocare Spark seems to be dominating. Let’s scan this table:

VitaminG Fuel (7g)Advocare Spark (7g)
Vitamin A1,000 IU 
Vitamin C250mg180mg
Vitamin E15IU30IU
Vitamin B1 (thiamin)3mg
Vitamin B2 (riboflavin)3.4mg
Vitamin B3 (niacin)15mg60mg
Vitamin B5 (pantothenic acid)50mg
Vitamin B6 (pyridoxine)10mg15mg
Vitamin B12 (cyanocobalamin)425mcg45mcg
Comparison of vitamins between G Fuel and Advocare Spark.

Evidently, Advocare Spark contains more types and higher amounts of vitamins compared to G Fuel which only has 5 kinds of vitamins.

Advocare boasts many types of B Vitamins in its formulation. B Vitamins are known to boost your energy and improve your cognition. Aren’t those the very reason why you feel the need for an energy drink?

Although Advocare has more vitamins, it also exceeds the daily recommended intake for a few of them which could potentially be dangerous. These are water-soluble, meaning the body will flush out the excess but if you’re wary, I suggest you take it up with your doctor.

Lastly, for me, Advocare Spark is the better choice if you’re not only after the physical and energy boost, but also the nutrition you can get from vitamins.


Once again, Advocare wins in the matter of minerals content as G Fuel really does not pack its formula in this aspect. Look at this table:

G Fuel (7g) Advocare Spark (7g)
Comparison of minerals between G Fuel and Advocare Spark.

Advocare Spark has three types of minerals: Zinc, Copper, and Chromium while G Fuel contains only one: sodium. Their choice of minerals serves different purposes too.

Sodium (commonly in a form of table salt) for instance, helps balance your body fluid by retaining water, but too much of it can increase your risk of high blood pressure.

Watch this video to learn when sodium is good or bad for you:

A video discussing the advantages and disadvantages of sodium (salt).

An amount of 79mg is deemed low-sodium as per the chart provided by the FDA, so know that you’re getting a small amount of sodium in every serving of G Fuel. You don’t need too much sodium for it to work in your body, after all.

Zinc, copper, and chromium, on the other hand, have different functions. Zinc supports cell growth, copper supports the production of red blood cells, and chromium helps control blood sugar.

These are all very important benefits that G Fuel simply does not offer.

Other Ingredients

G Fuel grouped its ingredients into three Complexes namely the Energy Complex, Focus Complex, and Antioxidant Complex while Advocare Spark contains only a few amino acids in comparison.

Comparison of ingredients between G Fuel and Advocare Spark.

Unlike Advocare Spark, I really like how G Fuel have stepped up their formulation by having a unique set of ingredients instead of sticking with the conventional ingredients of energy drinks like Taurine and Tyrosine.

In replacement, they’ve invested in plant-derived antioxidants which bring a plethora of health benefits that aren’t found in many energy drinks like the herbs Toothed Clubmoss and Bacopa Leaf Extract. This is where they bounce back from vitamins and minerals.

If you’re someone who decides which product to get based on the formulation, then G Fuel is the way to go.

Food Additives

G Fuel and Advocare Spark use almost the same additives in their formula, with the exemption of just one.

Citric AcidCitric Acid
Natural and Artificial Flavors Natural and Artificial Flavors
Silicon DioxideSilicon Dioxide
Acesulfame Potassium
Comparison of food additives between G Fuel and Advocare Spark.
G Fuel and Advocare Spark are sugar-free.

Both brands share the same types of food additives that keep their products fresh, their shelf-life longer, and their appearance pleasing.

The only thing that’s different is G Fuel has the artificial sweetener called Acesulfame Potassium in addition to its sucralose, which Advocare has.

Between the two sweeteners, they function similarly and the lack of the other isn’t entirely a loss. Advocare Spark will remain sweet even with just sucralose.

Who has a better selection of flavors?

G Fuel is available in more than 40 flavors while Advocare Spark has only 13 flavors.

Below are G Fuel’s bestselling flavors and Advocare Spark’s full list of flavors.

If you’re picky, I think you’d love the selection of flavors G Fuel offers. With over 40 flavor options it has, you can surely find something that’ll please your taste buds.

Advocare Spark, on the other hand, has pretty straightforward flavor names which I think is an advantage. This way you can save time choosing the flavors you like from its label as it gives a concrete idea of how a certain flavor will taste like. The downside, Advocare Spark’s flavors are quite basic and there are not many flavor options.

Who’s tougher than the other?

G Fuel is tougher than Advocare Spark.

It has higher caffeine content, more types of ingredients in its formulation that are not only all-natural but support your mental and physical functions. All of this will give you a good boost in both energy and concentration, all the while providing your body the nutrient it needs.

Though Advocare Spark comes close in its ingredients and caffeine, it won’t give you the same effects.

Final Thoughts

Upon going through a lot of details from both brands, I conclude that G Fuel is a tougher drink against Advocare Spark.

It has a stronger caffeine content of 150mg while Advocare Spark only has 120mg. It contains more amino acids and has unique plant-derived ingredients to help you boost your cognitive function while Advocare used a few conventional types of ingredients.

They both have the same price but I do think that with G Fuel’s formulation, it’s more deserving of your $35.99 a tub.
