King Maker is a men's health supplement sold by a company called Top Shelf Grind. It's marketed as promoting "Maximum Masculinity" and "Lean Muscle Growth."
But does King Maker contain research-backed ingredients for men's hormonal health? Does it contain any unhealthy ingredients? Are its ingredients dosed appropriately? And is King Maker better or worse than popular men's health supplements like Vintage Muscle?
In this article we'll answer all of these questions and more, as we analyze the ingredients in King Maker to give our take on whether or not it's likely to be effective for improving men's hormonal health, and whether or not it's healthy overall.
We'll also highlight some questionable health claims on the brand's website, and compare King Maker to other popular men's health supplements to pick our winners.
Key takeaways:
- Contains some active ingredients for male hormonal health
- Contains one inactive ingredient we consider unhealthy
- We do not currently recommend King Maker supplement
Ingredient Analysis
The vitamin and mineral blend in King Maker is shown below:
Vitamin D3 supplementation has been clinically shown to increase total testosterone levels by over 25% in men with mild vitamin D deficiency.
Magnesium is clinically shown to support optimal testosterone (T) levels in both active and sedentary men, as we documented in our Testoprime reviews article.
Zinc may also support T in men, although it may be sensible to speak with a doctor before regularly taking a nearly 300% Daily Value (DV) dose of any mineral.
The other active ingredients in King Maker supplement are shown below:
ViNitrox is clinically shown to support sports performance based on animal and in vitro studies, but we're underwhelmed by the clinical evidence as the studies were company sponsored and not randomized clinical trials.
Maca was shown to improve sex drive after eight weeks in a 2002 clinical trial, however, we're unable to locate safe dosing recommendations for maca extract.
Fadogia arestris extract was shown in a 2005 clinical trial to increase sexual behavior and testosterone levels in rats, but we can't find any trials with human participants showing the same effect.
Tongkat ali was shown in a 2017 medical review to improve male sexual health, but it may be underdosed in this supplement.
The tongkat dose used in every clinical trial in the above-linked review was at least 200% higher than the dose used in King Maker.
Overall, we're unimpressed by this botanical blend as we're unable to identify any ingredients clinically shown to improve men's sexual health outcomes at the included doses.
The inactive ingredients in King Maker are shown below:
Dicalcium phosphate is an unhealthy choice in our opinion, and we recommend avoiding phosphate additives in food and supplements wherever possible.
A clinical review published in a German medical journal described phosphate additives in food as a "health risk" due to potential harm to kidneys.
Overall, we consider King Maker potentially effective for natural male hormone support, primarily due to the vitamin and mineral ingredients.
We don't currently recommend this supplement because we consider the botanical blend to be poorly formulated, and due to the phosphate additive.
Extremely Strange Marketing Claims
The King Maker website suggests that this supplement will enhance physiognomy, which is the assessment of an individual's traits based on their facial appearance and expression:
The brand claims that their supplement was "developed with physiognomy in mind":
Facial bone structure is determined by a combination of genetics and puberty. You're not going to develop a "strong jaw" or a defined brow line that's associated with high T levels during development by taking an herbal supplement as a 30 year old man.
These suggestions are some of the stranger marketing claims we've come across in our hundreds of Illuminate Health articles.
In fact, facial bone changes during adulthood are almost all negative, caused by increasing bone loss and decreasing bone replacement.
King Maker vs. Popular Men's Health Supps
Here's how King Maker compares to other popular men's health supplements in terms of formulation quality and potential effectiveness, in our opinion:
Turkesterone
Clinically shown to have strength-enhancing effects, though most of the positive effects we've found were documented in animal studies.
Given lacking clinical data in humans and chemical nature of this compound, we consider it to be more of a long-term safety risk than King Maker.
Winner: King Maker
Vintage Muscle
One of the most dangerous men's health supplement brands.
This company was selling an illegal anabolic steroid at the time of our previous analysis of their website, as we documented in our Vintage Muscle review article.
Winner: King Maker
Testoprime
Contains green tea extract which can harm the liver at high doses.
Fewer active ingredients we consider effectively-dosed than King Maker.
Winner: King Maker
