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 to support these outcomes? Does it contain any questionable additives? Are its ingredients dosed appropriately? And how do real customer rate and describe the effects of King Maker?
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.
We'll also feature real King Maker customer reviews, and provide a cost comparison to show which retailer sells this supplement for the best price.
Formulation 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 botanical blend for King Maker is 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.
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 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 use of a 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.

Amazon: $129.99 (free shipping, link to official Amazon listing)
IBSpot: $46.06 (free shipping, third-party seller, link)
