Capsule Size Sets a Hard Ceiling on Any Formula

Here is the practical version, without the marketing.

What this actually means

A size 0 capsule holds roughly 400 to 500 mg of powder, a size 00 around 600 to 800 mg, and a size 000 approaches a gram while being difficult to swallow. That definition matters because the term gets used loosely in supplement marketing, where a real mechanism is routinely stretched into a promise the evidence does not carry.

It gives you a way to sanity-check any published dose list without needing the label at all.

Why it matters if you are buying a supplement

Almost every purchase decision in this category comes down to one question: is the product addressing the actual cause of the problem you have? Appetite, sleep debt, an energy surplus, insulin resistance and simple measurement error all produce similar-looking frustration, and they need different responses. Getting the cause right is worth more than getting the product right.

It gives you a way to sanity-check any published dose list without needing the label at all. That is why the sequence on this site is always the same — understand the mechanism, check the dose against the research, then decide whether a product is buying you anything.

Four things worth knowing

• Add the advertised amounts and compare against capsule capacity.
• A total far above 800 mg in one capsule deserves a question.
• Botanical powders vary in density, so the figures are approximate.
• An impossible total usually means a raw-equivalent figure is in the list.

What to do about it

1. Add up the published amounts before believing them.
2. Ask what capsule size is used if the total looks high.
3. Treat an impossible total as an extract-ratio question.
4. Prefer products where the arithmetic works.

None of those cost anything, which is the point. For erectile function the interventions with the strongest evidence — treating blood pressure, managing glucose and cholesterol, losing excess weight, stopping smoking and regular aerobic exercise — are consistently cheaper and far less marketed than the ones with the weakest.

One more framing point. Effect sizes in this field are usually small, and small effects are exactly the ones personal impression cannot detect — especially where expectation does as much work as it does in this category. A written record beats a memory every time.

It is also worth separating what is measurable from what is marketable. The interventions with the strongest evidence here rarely have a product attached, which tells you something about why you hear about them least.

The myth to drop

That formulators can fit any advertised amount into one capsule.

Where Horsewood fits

Horsewood official website is a once-daily male vitality capsule built around seven named botanicals: Tongkat Ali, horny goat weed, saw palmetto, nettle, wild yam, sarsaparilla and boron chelate. No Supplement Facts panel is published for it on either page selling it. One competing page advertises Tongkat Ali at 1,000 mg, horny goat weed at 80 mg and the other five at 20 mg each; the other publishes no amounts at all.

Read against this topic, the honest placement is as a background botanical layer rather than a solution. Boron has a specified-dose study behind it and Tongkat Ali has genuine human research at 200 mg of a standardised extract. Five of the seven sit far below their researched intakes, and the whole category is the one the FDA most often finds adulterated with undeclared prescription drugs. It belongs underneath a blood pressure check and a conversation with a pharmacist, never in place of them. The detail is on what Horsewood is.
