Joker is a 6-capsule food supplement for men combining two mushroom extracts with several plant ingredients, L-arginine, oyster extract and a zinc amino acid chelate.
The formula is not built around a single ingredient. Cordyceps and Reishi are combined with black ginger, ginger, Maca, pumpkin seed, lycopene, L-arginine, oyster extract and a zinc-related chelate ingredient.
Which ingredients stand out in the Joker formula?
Milligram values alone do not tell the whole story. Joker contains extracts, a powder, an amino acid, a mineral chelate and technological ingredients, so the form in which each ingredient appears on the label also matters when comparing products.
• Cordyceps extract – 80 mg
• Reishi mushroom extract – 80 mg
• Black ginger extract – 50 mg
• Oyster extract – 50 mg
• Ginger extract – 50 mg
• L-arginine – 50 mg
• Maca (Lepidium meyenii) powder – 50 mg
• Lycopene (10%) – 35 mg
• Pumpkin seed extract – 30 mg
• Zinc, amino acid chelate 20% – 20 mg

Cordyceps and Reishi – two mushroom extracts at the core of the formula
Cordyceps extract and Reishi mushroom extract are present at 80 mg each, making them the largest plant- or mushroom-based ingredients in the formula by declared weight.
Cordyceps preparations have been studied in humans in relation to physical exertion, endurance and recovery. Results are not fully consistent, and the products used in research can differ considerably in species, processing, extract concentration and dose.
For the buyer, this means that the 80 mg Cordyceps extract in Joker should not automatically be considered equivalent to another Cordyceps product that specifies a particular species, extract ratio or marker compound.
Reishi has also been investigated in human studies in a number of areas related to general wellbeing and physical load. The strength and consistency of the evidence varies depending on the outcome being studied.
The Joker label does not provide an extract ratio or marker compound for either mushroom extract. We therefore do not assign undeclared amounts of polysaccharides, cordycepin, triterpenes or other compounds to the product.
Black ginger – why is it used in formulas for men?
Black ginger has been studied in humans in relation to areas including physical performance and certain aspects of male sexual function.
This research background helps explain why black ginger can appear in multi-ingredient formulas designed for men.
Joker contains 50 mg of black ginger extract per capsule.
The label does not state the exact botanical species, extract ratio or level of standardisation. General research on black ginger therefore cannot be treated as proof of a guaranteed effect from the finished Joker product.
L-arginine and the nitric oxide pathway
L-arginine is an amino acid involved in the body's production of nitric oxide. Nitric oxide acts as a signalling molecule and is involved in the regulation of vascular tone and relaxation of vascular smooth muscle.
This physiological role explains why L-arginine frequently appears in formulas intended for men.
Joker provides 50 mg of L-arginine per capsule.
The physiological role of L-arginine in nitric oxide metabolism does not prove that the finished Joker product produces a specific or guaranteed effect on erection, potency or circulation.
Maca – with the botanical name stated on the label
Joker contains 50 mg of Maca (Lepidium meyenii) powder per capsule.
Maca has been studied in humans in relation to sexual interest and certain measures of sexual function. The overall scientific evidence remains limited, so these studies cannot be used to claim a guaranteed effect from Joker itself.
When comparing formulas, it is also important that the Joker label specifies Maca powder, not a 10:1, 20:1 or otherwise concentrated Maca extract.
Oyster extract – 50 mg without a declared zinc amount
Oysters are known as foods with a notable mineral profile, including naturally occurring zinc. This does not, however, tell us how much zinc is present in a particular oyster extract.
Joker provides 50 mg of oyster extract per capsule, but the label does not state a separate amount of zinc or another marker compound for that extract.
Joker contains oyster extract. Oyster is a mollusc-derived ingredient. Anyone with an oyster or mollusc allergy should take this into account when selecting the product.
Zinc amino acid chelate 20% – what does the 20 mg mean?
This is one of the most important details to interpret correctly on the Joker label.
The label states “Zinc, amino acid chelate 20% – 20 mg.”
This is not the same as saying that one Joker capsule contains 20 mg of elemental zinc.
A mathematical value could be derived from the 20% specification, but the physical label does not separately state “of which zinc” or provide an NRV value. We therefore do not convert the chelate amount into our own declared elemental zinc dose.
Authorised health claims exist for zinc, including claims relating to normal fertility and reproduction and the maintenance of normal testosterone levels in the blood. Such claims can only be used when the relevant conditions of use are met. Since the Joker label does not provide a separate elemental zinc amount or NRV value, these claims are not automatically attributed to the finished product.
Pumpkin seed and lycopene – why can they appear in men's formulas?
Pumpkin seed preparations and lycopene have both been investigated in areas of male urological research, including research concerning the prostate and lower urinary tract.
This does not establish a specific prostate effect from the 30 mg pumpkin seed extract or the 35 mg 10%-labelled lycopene ingredient in Joker.
For a buyer, the research background is more useful as an explanation of why these ingredients may be included in a multi-component formula for men.
What does “Lycopene (10%) – 35 mg” mean?
The physical label lists 35 mg of an ingredient identified as Lycopene (10%).
Although a smaller lycopene value could be calculated mathematically from the percentage, the label does not present this as a separate “of which lycopene” amount. We therefore do not add our own declared lycopene dose.
How should Joker be taken?
The directions on the physical label are:
Take 1 capsule daily with a meal and a glass of water.
Do not exceed the recommended daily amount.
The label does not specify a timing schedule in relation to sexual activity.
There is therefore no label-based reason to recommend taking Joker 30 minutes, 1 hour or 2 hours before intercourse. The confirmed directions are simply 1 capsule daily with a meal and a glass of water.
Who should not use Joker?
According to the physical label:
• Not recommended for persons under 18 years of age.
• Not recommended for persons with high blood pressure.
• Not recommended for persons with cardiovascular disease.
• Keep out of reach of children.
If you regularly take medicines or have a known medical condition, it is sensible to consult a doctor or pharmacist before using a food supplement.
Storage, capsule material and origin
According to the label, Joker should be stored protected from light and heat.
The capsule material contains 100 mg of gelatin, so Joker is not suitable for a vegetarian or vegan diet.
Origin: EU.
Food supplements should not be used as a substitute for a balanced, varied diet and a healthy lifestyle.
Important note about the weight information on the package
The weight information printed on the physical package is not fully consistent.
The stated net weight is 3.5 g, while the same label also states 600 mg × 6 capsules. Mathematically, this would equal 3.6 g.
In addition, the sum of the individually listed ingredients is 597 mg per capsule.
We do not correct this discrepancy by making our own assumption. The reliably confirmed information is that the package contains 6 capsules and the recommended serving is 1 capsule daily.

Should Joker be taken a certain time before intercourse?
No intercourse-related timing is stated on the physical label. The confirmed directions are 1 capsule daily with a meal and a glass of water, and no fixed onset time is specified.
Why does Joker contain L-arginine?
L-arginine is an amino acid involved in the body's production of nitric oxide. This physiological role helps explain why it is used in formulas for men, but it does not mean the finished Joker product has a guaranteed effect.
What should I know about the Maca in Joker?
Joker contains 50 mg of Maca (Lepidium meyenii) powder per capsule. Maca has been studied in relation to sexual interest and sexual function, but the overall evidence is limited. The label specifies powder rather than a concentrated extract.
Does Joker contain 20 mg of elemental zinc?
No. The label states 20 mg of a zinc amino acid chelate with a 20% specification. It does not separately declare 20 mg of elemental zinc.
Does Joker contain oyster extract?
Yes. One capsule contains 50 mg of oyster extract. Oyster is a mollusc-derived ingredient, so people with an oyster or mollusc allergy should take this into account.
Can Joker be used by people with high blood pressure?
According to the physical label, Joker is not recommended for people with high blood pressure. It is also not recommended for people with cardiovascular disease.
Is Joker suitable for people under 18?
No. According to the physical label, Joker is not recommended for persons under 18 years of age. It should also be kept out of reach of children.
Is Joker vegetarian or vegan?
No. The capsule material contains 100 mg of gelatin per capsule, so Joker is not suitable for a vegetarian or vegan diet.
