Green Tea Extract
The formula's only source of caffeine, and the ingredient carrying its most important safety note.
Green Tea Extract in the Horsewood Formula
Camellia sinensis — amount per capsule not published.
In one line: Genuinely researched polyphenols, and the one ingredient where a concentrated extract behaves differently from the drink.
The formula’s only source of caffeine, and the ingredient with the most important safety note attached.
What Green Tea Extract Is, Before the Horsewood Framing
Green tea extract is a concentrated preparation from Camellia sinensis leaves, standardised to its catechin content — principally epigallocatechin gallate, usually abbreviated EGCG.
The important distinction, and the one that matters for safety: an extract is not a cup of tea. Drinking green tea delivers modest amounts of catechins in a large volume of water. A concentrated extract can deliver many times that in a capsule, and the two have different risk profiles.
Green tea also contains caffeine, and the seller identifies this as the only caffeine in Horsewood.
What the Green Tea Research Behind Horsewood Found
A substantial research literature, with results that are real but generally modest.
Antioxidant activity. Catechins are well-characterised polyphenols with demonstrable antioxidant properties in laboratory measurement, and EGCG is among the most-studied plant compounds in existence.
Metabolism. Research on green tea catechins and energy expenditure has found small effects, often in combination with caffeine, and the practical significance is limited.
Cardiovascular and observational research generally associates green tea consumption with favourable outcomes, with the usual caveat that tea drinkers differ from non-drinkers in many other ways.
Amounts used in trials vary widely, commonly delivering a few hundred milligrams of catechins a day.
What Green Tea Extract's Inclusion Means in Horsewood
It is a reasonable component of an antioxidant group, and it explains the caffeine note on the seller's page, which is handled honestly — stating that the only caffeine is the small natural amount from this ingredient, well below a cup of coffee, is a fair and useful disclosure.
Neither the amount nor the catechin standardisation is published, which for this ingredient is more consequential than for most, because the safety consideration below scales with the concentrated catechin dose rather than with the ingredient's presence.
Green Tea Extract Safety in Horsewood
This is the ingredient safety note most worth reading in the whole formula.
- Liver injury. Concentrated green tea extracts have been associated with rare cases of liver injury, and several regulators and expert bodies have reviewed the issue. The risk appears related to high catechin doses taken in concentrated form, particularly on an empty stomach — not to drinking tea.
- Take with food. Guidance generally suggests taking green tea extract with a meal, which the seller's morning-with-breakfast recommendation happens to satisfy.
- Stop and seek advice if you develop unusual fatigue, abdominal pain, dark urine or yellowing of the skin or eyes.
- Caffeine sensitivity. The amount here is described as small, but it is not zero and it is not published.
- Iron absorption. Catechins can reduce non-haem iron absorption, relevant if you are managing iron deficiency.
Horsewood names thirteen ingredients and doses none of them
This is the single most important thing to understand about the product, and it is awkward because the seller makes the opposite claim its headline selling point.
Its own words: "No Proprietary-Blend Games". "Named Doses, Not a Blend Fog". Thirteen ingredients "you can look up individually — not a fog of complexes with undisclosed amounts". "Each named, none hidden."
Yet no milligram figure is published for any of the thirteen. Not on the homepage, not in the ingredients section, not in the FAQ. The ingredients are named. They are not dosed. Those are different things, and only one of them lets you evaluate a formula.
To be fair, avoiding a proprietary blend is genuinely better than hiding ingredients inside one, and naming all thirteen is more than many competitors do. But a named ingredient with no amount attached tells you what is in the bottle without telling you whether there is enough of it to matter.
Why this matters arithmetically. A standard capsule holds roughly 500–800 mg of material in total. The studied amounts above, added together, come to several grams a day. Thirteen ingredients cannot all appear at their researched amounts inside one capsule — there is not physically room. That is not an accusation about this product; it is true of every thirteen-ingredient single-capsule formula, and it is exactly why the amounts should be published.
The one question worth asking the seller before you buy is for the milligram amount of each ingredient per capsule. Given that dose transparency is their headline claim, it is a fair question, and the answer would be a single line.
How to read the research described on this Horsewood page
The studies referred to here examined individual ingredients on their own, at the amounts the researchers chose — typically hundreds of milligrams a day, and for maca and spirulina, grams.
That research explains why an ingredient is of interest. It does not show that Horsewood reproduces those results. No clinical trial of this finished formula has been published, and because the seller publishes no amount for any ingredient, the comparison cannot be completed from the outside. Nothing on this site estimates the missing figures.

Horsewood Safety Notes
Horsewood safety and sensible precautions
The reference's own guidance is sound and is repeated here, with a few ingredient specifics added that it does not mention.
- Do not use if pregnant, nursing or under 18. The seller states this directly.
- Show the label to your doctor if you take prescription medication or manage a diagnosed condition — the seller's own advice, and it specifically says show the label rather than a summary of it.
- Ginkgo and bleeding risk. Ginkgo has documented interactions with anticoagulants and antiplatelet drugs, and is normally stopped before surgery. This is the most clinically significant interaction in the formula.
- Green tea extract and the liver. Concentrated green tea extracts have been associated with rare liver injury, which is why several regulators have looked at them. The amount here is not published.
- Thyroid medication. Ashwagandha may increase thyroid hormone levels, which matters if you take levothyroxine or manage a thyroid condition.
- Zinc. If you already take a multivitamin or a separate zinc supplement, you cannot check for overlap here, because the amount is not published. The adult upper limit is 40 mg a day from all sources.
- Autoimmune conditions. Echinacea is traditionally cautioned against in autoimmune disease because of its immune-stimulating framing; discuss it with your doctor.
- Caffeine. The seller states the only caffeine is the small natural amount in green tea extract, which is far below a cup of coffee.
Horsewood is a dietary supplement, not a medicine, and it is not intended to diagnose, treat, cure or prevent any disease.
When to see a doctor rather than buy Horsewood
Low energy, poor focus and feeling worn down are exactly the symptoms most likely to send someone to a supplement page, and they are also the symptoms most likely to have a diagnosable cause.
Persistent fatigue can reflect iron deficiency or anaemia, an underactive thyroid, sleep apnoea, depression, diabetes or vitamin B12 deficiency. Every one of those is identifiable with a straightforward blood test or assessment, and every one is treatable. A blood panel costs less than a six-bottle order.
New or worsening difficulty concentrating, especially with mood change or sleep disruption, is worth discussing rather than supplementing around.
Chronic stress that is not resolving is a health issue in its own right. Adaptogens are not a substitute for addressing it.
To the reference's credit, it says something similar: it tells readers to check with a doctor and states that the product supports everyday wellness rather than treating any condition. That is the right advice and it is repeated here.
