Evidence: This comparison is based on Erexon’s disclosed Amazon listings, independent trial data on its ingredients and price per tablet — not on promised effects.
Timing: Erexon is designed to be taken as-needed before activity; a daily food supplement is taken as part of an ongoing routine, not before a specific occasion.

Erexon (Intense Blue) is a UK-sold herbal food supplement for men, built around Korean ginseng and Tribulus Terrestris, with maca and zinc added in some versions. It is sold as fast-acting blue tablets on Amazon UK, in packs of 10, 20 and 30, at roughly £13–£23. Of its main ingredients, only zinc carries an EFSA-authorised claim; the herbal components are traditional botanicals with limited human-trial evidence. This review looks at what is in it, what the evidence actually supports, how to use it sensibly, and how it compares to a daily formula.

What Is Erexon (Intense Blue)?
Erexon (listed as ErexOn on Amazon) is a men’s herbal food supplement sold in the UK as “Intense Blue” tablets. It is one of dozens of fast-acting blue-tablet products in the Amazon UK ginseng category, and one of the longer-established ones — the original 20-tablet listing has been live since June 2022 and has gathered around 455 reviews at a 4.1-star average. That makes it more reviewed than most rivals in this crowded niche.
The range is sold in a few formats. The figures below are taken from the public Amazon UK listings at the time of writing; pack sizes and prices change often, so always check the current page before you buy.
| Format | Pack | Approx. price | Listed ingredients |
|---|---|---|---|
| Intense Blue (10) | 10 tablets | £12.95 | Korean ginseng, Tribulus Terrestris |
| Intense Blue (20) | 20 tablets | £19.85 | Korean ginseng, Tribulus Terrestris |
| Intense Blue (30) | 30 tablets | £22.90 | Korean ginseng, Tribulus Terrestris |
| ErexOn V (10) | 10 tablets | £9.90 | Maca, glycine, Korean ginseng, zinc |
Ingredients: What’s Actually in Erexon?
Across the range, four ingredients do the work: Korean ginseng, Tribulus Terrestris, maca and zinc. Erexon’s listings describe the herbal content but do not always publish exact milligram doses for every component, which is common in this part of the market. Here is what each one is and what it is used for.
Korean Ginseng (Panax ginseng)
Korean ginseng is the headline herb in the Intense Blue tablets. It is a traditional Asian botanical taken for general energy and wellbeing, and it is the most-studied ingredient in this category — though most trials are small. Our Korean ginseng guide for men goes through the research in detail.
Tribulus Terrestris
Tribulus Terrestris is a flowering plant used in traditional herbal practice. It appears in the product name and is one of the two named botanicals in the Intense Blue tablets. The human evidence is limited and mixed — we cover what the trials do and don’t show in our Tribulus Terrestris guide.
Maca
Maca (Lepidium meyenii) is a Peruvian root included in the ErexOn V version. Small trials have looked at maca for subjective sexual desire, with mixed results and no consistent effect on hormones.
Zinc
Zinc is a dietary mineral, included in the ErexOn V version. It is the only ingredient in the range that carries an EFSA-authorised health claim, which we cover in the next section.
What the Evidence Supports
Here is the honest position: of Erexon’s ingredients, only zinc has a claim that UK and EU regulators have formally authorised. The herbal ingredients are sold on the basis of traditional use, and their human-trial evidence ranges from limited to mixed.
Zinc: the one authorised claim
Where a product contains a meaningful amount of zinc, two EFSA-authorised statements may be used, word for word:
These are the only authorised wordings for zinc in this context. They apply to zinc as a nutrient, not to the herbal blend as a whole, and only when the product supplies enough zinc to qualify. Erexon’s herbal-only Intense Blue tablets do not list zinc; the ErexOn V version does.
Tribulus Terrestris: traditional use, limited evidence
Tribulus Terrestris is used in traditional herbal practice, but it does not hold an EFSA-authorised health claim, and the human trial evidence is limited and inconsistent. It should be understood as a traditional botanical rather than a proven active.
Korean ginseng and maca: small, mixed trials
Korean ginseng has several small human trials for energy and general wellbeing, and maca has small trials looking at subjective sexual desire. In both cases the studies are small and the results mixed, and neither holds an EFSA-authorised claim for these uses. They are reasonable traditional ingredients, but the evidence is not strong enough to make firm promises.
Dosage & How to Use It
Erexon is sold as an “as-needed” product — the listings position the tablets as fast-acting, to be taken before activity. That is a different model from a daily nutrient formula, which is a fully disclosed food supplement taken as part of a varied diet, as needed, up to one tablet a day.
- Always follow the dose printed on the pack you buy — do not exceed it.
- Because it is taken occasionally, a 10- or 20-tablet pack can last a while; work out cost per tablet, not just headline price.
- If you want a fully disclosed formula where every dose is listed and checkable, an undisclosed as-needed tablet is not the right tool — a transparent daily formula is.
- Food supplements should not replace a varied and balanced diet and a healthy lifestyle.
Safety & Red Flags
Erexon is a food supplement, so the general safety picture is reassuring — but there are sensible checks for any product in this category.
- Undisclosed doses: if a listing names ingredients but hides the milligram amounts, you cannot judge whether the herbs are present in meaningful quantities.
- Medicinal-sounding claims: a food supplement cannot legally claim to treat or cure any condition. Promises of that kind are a warning sign, not a feature.
- Doubling up on zinc: if you already take a multivitamin or another men’s formula, check your total zinc stays below the 40 mg upper limit.
- Medication and conditions: if you take prescription medicine or have a medical condition, speak to a pharmacist or GP before using any herbal product, as some botanicals can interact.
None of this is unique to Erexon — it applies across the whole “blue tablet” shelf. The brands worth trusting are the ones that publish full doses and avoid medicinal promises.
Erexon vs a Daily Formula
The most useful comparison is not Erexon against another fast-acting tablet, but Erexon against a different type of product: a fully disclosed daily formula, taken as needed, up to one tablet a day. They are built for different jobs.
| Feature | Erexon (Intense Blue) | A daily formula (e.g. Blue Power) |
|---|---|---|
| Use pattern | As-needed, before activity | As needed (up to 1 tablet a day) Flexible |
| Korean ginseng | Yes (dose not always listed) | Yes, standardised concentrate Specified |
| Tribulus Terrestris | Yes Included | Not in core formula |
| Zinc (EFSA claim) | Only in ErexOn V version | 10 mg, 100% NRV Daily |
| Dose transparency | Partial | Full doses listed Full |
| Caffeine / stimulants | None declared | None Equal |
| Reviews | ~455 at 4.1 stars Established | Direct-from-brand |
| Price | ~£12.95–£22.90 (10–30 tabs) | 30 tablets (30 servings) — check current price |

How Blue Power Compares
Blue Power is a daily, caffeine-free tablet rather than an as-needed one. It shares Erexon’s Korean ginseng base but takes a different overall approach: every ingredient dose is published, and zinc is included at 100% of the nutrient reference value so the authorised EFSA wording applies.
Where Blue Power Differs
Blue Power is built as a foundation supplement — fully transparent dosing, no stimulants:
- Korean ginseng (5:1 concentrate): the shared base ingredient, at a specified, standardised dose.
- Zinc 10 mg (100% NRV): Zinc contributes to the maintenance of normal testosterone levels in the blood. Zinc contributes to normal fertility and reproduction.
- Vitamin C 80 mg (100% NRV): Vitamin C contributes to the reduction of tiredness and fatigue. Vitamin C contributes to normal energy-yielding metabolism.
- Full dose disclosure: every ingredient amount is listed on the label — no hidden quantities.
Designed for daily use as part of a varied and balanced diet and a healthy lifestyle.

Reporting side effects. Food supplements are generally well tolerated, but if you notice an unexpected reaction to any supplement you can report it to the UK regulator through the MHRA Yellow Card Scheme. Always tell your GP or pharmacist about supplements you take, especially alongside prescription medicines.
Editorial note — no product-specific evidence behind an as-needed pill: The honest reading here is that Erexon (Intense Blue) is marketed as a fast-acting herbal tablet without a published, per-tablet ingredient list, so there is no product-specific trial evidence to weigh. The main limitation is transparency: without disclosed doses you cannot check any ingredient against the research behind it. One honest caveat — even where the underlying botanicals have some human data, those findings belong to the specific extract and dose studied and cannot be transferred to a branded blend as a claim.
— Blue Power Research TeamFrequently Asked Questions
What is Erexon (Intense Blue)?
Erexon (listed as ErexOn) is a men’s herbal food supplement sold in the UK as “Intense Blue” tablets on Amazon. It is built around Korean ginseng and Tribulus Terrestris, with maca and zinc in some versions. It is a food supplement, not a medicine, and is sold in packs of 10, 20 and 30 tablets.
What ingredients are in Erexon Intense Blue?
The core Intense Blue tablets list Korean ginseng and Tribulus Terrestris. The ErexOn V version lists maca, glycine, Korean ginseng and zinc. Exact milligram doses are not always published on the listings, which is common in this category — always check the current Amazon page for the full ingredient panel.
Does Erexon work?
Of its ingredients, only zinc carries an EFSA-authorised claim, and only in versions that contain enough of it. Tribulus Terrestris has limited and mixed human evidence and no authorised claim. Korean ginseng and maca have small, mixed trials. So the honest answer is that the regulated evidence is modest, and any strong promises about the product should be treated with caution.
Is Erexon safe?
Erexon is a food supplement, so for most healthy adult men it is low-risk when used as directed. Do not exceed the dose on the pack. If you take prescription medication, have a medical condition, or already take other supplements with zinc, speak to a pharmacist or GP first, as some herbal ingredients can interact.
How much does Erexon cost?
On Amazon UK, prices run from roughly £12.95 for 10 tablets to about £22.90 for 30 tablets, with a 20-tablet pack around £19.85. Because it is an as-needed product, work out the cost per tablet rather than just the headline price. Prices change, so check the current listing.
Erexon or a daily formula — which should I choose?
It depends on what you want. Erexon is an as-needed tablet for the occasional moment. A formula such as Blue Power is taken as needed, up to one tablet a day, for nutritional support, with fully disclosed doses and zinc at 100% NRV so the EFSA-authorised wording applies. Match the product to how you actually want to use it.
The Bottom Line
Erexon (Intense Blue) is an established, reasonably well-reviewed entry in a very crowded category. It is built on Korean ginseng and Tribulus Terrestris, with maca and zinc in one version. Its strengths are its track record and the number of reviews behind it. Its weaknesses are the ones shared by most of this shelf: partial dose disclosure and a reliance on herbal ingredients whose regulated evidence is limited — only zinc carries an authorised claim, and only in the version that contains it.
If you want an as-needed tablet from a familiar marketplace brand, Erexon is a fair pick. If you would rather have a daily, fully-dosed formula with transparent labelling and the authorised EFSA nutrient wording, a daily product like Blue Power is built for that job instead. There is no single “best” — the right choice depends on how you want to use it.
