Skald Oxydynamic Fat Scorcher is a weight loss supplement. The company claims that their product can improve energy and lead to fat loss.
In this article we’ll review the ingredients in Skald based on medical research to determine if it’s likely to be effective. We’ll also explain why we disagree with their labeling.
Proprietary Blend Labeling
Skald lists their ingredients in the format of a “proprietary blend”, which means that the company lists the dose of all of the ingredients combined, but not the dose of all of the individual ingredients.
This is obviously an issue because it disallows consumers and researchers from looking at each ingredient and analyzing whether it’s effectively dosed.
We find proprietary blends to be unethical. Manufacturers will claim that it allows them to protect “trade secrets”, which doesn’t follow logically since most supplements (including Skald) have never been tested in medical research to prove their effectiveness anyway.
The main way that prop blends benefit manufacturers is it allows them to include tiny, insignificant amounts of exotic ingredients to fill out their Supplement Facts label. So a company might have a product with 100 milligrams (mg) of ashwagandha extract and 0.001 mg of valerian and 0.001 mg of St. John’s Wort.
The prop blend would simply report a total dosage of 100.002 mg of the three ingredients, which would lead consumers to believe that they were similarly dosed.
We generally recommend avoiding supplements using a prop blend, especially if the supplement hasn’t been proven to work in published medical research (which Skald hasn’t).
The first ingredient in Skald is caffeine at a modest dosage of 110 mg, which is a bit more than you’d get from a single cup of coffee.
While there is some medical research suggesting that caffeine supplementation can cause weight loss, there isn’t much evidence at lower levels such as 110 mg. The effect seems to be more significant at higher doses of caffeine.
N-Acetyl-Tyrosine is the second ingredient in Skald, and it’s an amino acid. We can’t find any research suggesting this ingredient is effective for weight loss, and in fact we found the opposite. One animal study found that tyrosine was effective for increasing appetite.
The third ingredient is green tea leaf extract, and this is a popular ingredient in many weight loss formulations, such as ProbioSlim which we recently reviewed. As we discussed in greater detail in that review, we don’t recommend this ingredient, especially when the dosage isn’t published, because high levels of it have been associated with safety risks due to toxicity.
Green tea leaf extract does appear to be effective for short-term weight loss, but we don’t recommend it due to the safety concerns.
Juniper extract is the next ingredient listed, and we can’t find a single study testing this ingredient for weight loss outcomes. Skald doesn’t publish any research so we’ll assume this ingredient is entirely ineffective.
White willow bark extract is the next listed ingredient, and again we can’t find one single medical trial suggesting this is an effective ingredient for weight loss. This botanical is typically used for pain, because its active chemical compound salicin was used in the initial Asprin formulation.
The next two ingredients, verbascum thapsus leaf powder and elecampane root powder, also seemingly have no research backing their effectiveness for weight loss. We can’t locate one study testing either ingredient for effects on weight.
Skald's website describes elecampane as "used since Jesus Christ walked the earth to relieve the symptoms of lung complaints." We have no idea why they're including a compound for lung complaints in a weight loss formula, but their formulators seem totally incompetent and that quote should tell you all you need to know about this company.
The final ingredient is piperine, which is a compound extracted from black pepper. We found one animal study suggesting this ingredient may be effective for weight loss, but it’s almost certainly underdosed in Skald. The dose used in the experiment was 40 mg per kilogram (kg), which would be equivalent to a 3,200 mg dose for an average-weight man.
The entire prop blend of Skald is 356 mg, and piperine is the least-potent ingredient as it’s listed last, so we will conclude this ingredient is underdosed.
Overall this is a very poor formulation, with only three ingredients even potentially beneficial for weight loss based on our review, and none of them being effectively dosed.
Skald also contains an inactive ingredient called titanium dioxide which has been banned in the E.U. due to toxicity concerns. We recommend avoiding this ingredient.
If you want to leverage caffeine to induce weight loss, we believe that drinking plain black coffee would be safer and more effective than taking Skald. Black coffee has health benefits outside of the weight loss alone, and is also cheaper than this supplement if made at home.
We recommend that patients considering black coffee for weight loss speak with their doctor first, since coffee can increase blood pressure and pulse in some patients.
Increasing dietary fiber is another great lifestyle alternative which can aid significantly in weight loss. The level of fiber intake in the diet predicts weight loss based on a medical study published in The Journal of Nutrition.
The number of medical studies proving that increased fiber intake causes weight loss is significantly more than the number of medical studies suggesting that weight loss supplements are effective.
The cheapest way to increase dietary fiber is by cooking dried beans in bulk and adding them to daily meals, but there exist fiber supplements as well such as acacia fiber which come in powder form and can be added to water or coffee for convenience.
Adding fiber powder to black coffee should be a great combination for weight loss.
