Choosing A Focus Supplement

A proprietary blend is a legal way of listing several ingredients under one shared total. The list is real and the total is real. What goes missing is the split between them, and the split is the entire question.

Work through the arithmetic once and it applies to every blend you will ever read. Seven ingredients sharing 151 mg means no single one exceeds 151 mg, and six must sit below whatever the largest one takes. If an ingredient's trials used 300 mg a day, the blend cannot contain a trial dose of it even if that ingredient took the whole line and the other six took nothing.

So a blend total is not useless. It is a ceiling, and a ceiling is a real piece of information: it can rule an ingredient out, which is often all you need. What it cannot do is rule one in, and the makers who use blends know that the two look similar on a shelf.

The stated reason for a blend is recipe protection. The practical effect is that a product can carry an impressive ingredient list at amounts nobody outside the factory can check, and that the cheapest ingredients can be the largest share without anything on the label being untrue.

One kind of ingredient escapes this, and it escapes in a way worth watching. Anything active in microgram amounts, huperzine-A being the common example, fits inside any blend at its full researched dose. Its presence cannot be ruled out by arithmetic, which is exactly why its absence from the numbers deserves more attention than a botanical's.

Running the checklist over the product this website sells is the only way to show it is a checklist. Here is the panel, check by check, with the result first and the reasoning beside it.

Read from the printed label artwork rather than from the seller's summary copy. Four passes, one partial, two fails.

Both failures come from the same line on the panel. 7 ingredients share 151 mg, so no individual amount can be verified and the caffeine figure goes with them.

Put that ceiling beside the doses from the ingredient guide and the consequence is arithmetic rather than opinion. Bacopa's trials used 300 mg a day for twelve weeks, which is twice the whole blend. Rhodiola's used 400 to 576 mg. Theacrine's used 125 to 400 mg. Theobromine did anything at all only in the hundreds of milligrams. Tyrosine's trials are in grams. Caffeine's alertness effects are strongest above 200 mg. Six of the seven have researched doses that cannot fit inside the total even alone.

The seventh is huperzine-A, whose trials run at 0.4 to 0.8 mg a day. That fits easily, which makes it the one ingredient here that could genuinely be present at a studied amount. It is also the only one that works by inhibiting an enzyme, in the same class as prescription dementia drugs, and Cochrane judged its evidence inadequate for a recommendation while noting it is pharmacologically active in microgram quantities. So the ingredient with the strongest reason to want a figure is inside the part of the panel that has none.

That is the honest shape of this label, and it is why the passes are worth something rather than nothing. A real blend total, printed vitamin amounts, standardisation on two botanicals, honest serving arithmetic and a refund route with an address on it are all more than many labels in this aisle manage. A buyer who wants milligram certainty should buy single-ingredient products, and this checklist says so.

A comparison of label formats rather than of brands. All three are things you can buy from many sellers.

The pattern is consistent and it is worth stating as a rule. The fewer ingredients a product has, the better it tends to score on this checklist, because there is less reason to hide anything and more room for each amount. Breadth and verifiability pull against each other, and a product cannot fully have both.

Which side to take is a genuine preference rather than a right answer. Someone who wants to know exactly what they are taking should buy fewer things at printed amounts. Someone who wants a single capsule covering several mechanisms is accepting a blend line, and should at least know that is the trade being made.

This checklist measures one thing: whether a label can be read and held against published research. That is necessary and it is nowhere near sufficient, and a guide that pretended otherwise would be making the same mistake as the labels it criticises.

A perfectly transparent label can print a researched dose of an ingredient whose research is weak. The reviews of this category found the evidence inconsistent and often methodologically flawed across the board, and a review of 103 memory supplements sold in United States pharmacies found little that was firmly established. Transparency tells you what you are taking. It does not promise the thing is worth taking.

Two more limits are worth naming. A label cannot tell you whether the capsule contains what it says, which is what independent testing is for and what a lot number alone does not establish. And it cannot tell you whether an ingredient interacts with something you already take, which depends on your prescriptions rather than on the panel.

Used within those limits the seven checks do a specific job well. They let you compare two bottles honestly, rule out the products that have decided you do not need the numbers, and know which questions are still open once you have bought.
