How to Read a Supplement Label in 90 Seconds

This is the method. It works on any bottle, in a shop or on a website, and it will save you more money than any single piece of product advice.

1. Serving size, and servings per container ⏱️

Start here, because every other number on the panel depends on it. “Per serving” of what — one capsule, two, four? A bottle of 60 capsules at a four-capsule serving is a fifteen-day supply, which changes the real price per month by a factor of four.

Then check the dosing schedule. If the trials behind an ingredient split the dose twice daily and the product is once daily, that is a mismatch worth noticing.

2. Is each amount disclosed? 🔍

Look for a proprietary blend — one total weight covering several ingredients, with no individual figures. If you see one, you cannot evaluate the formula on paper. That is not automatically disqualifying, but it moves the entire decision onto trust and the refund policy.

Where amounts are disclosed, you are in a position to do real work. Where they are not, skip to step seven.

3. Check the order of the list 📋

Ingredients must be listed in descending order of weight. The first two or three names carry most of the mass. If the ingredient you are buying the product for appears eighth of ten, you are mostly buying the first two. 🧐

4. Look for standardisation 🧪

“Milk thistle extract, standardised to 80% silymarin” is a different claim from “milk thistle.” Standardisation names the active compound and guarantees a percentage, which is what makes a dose comparable to a trial dose. A bare plant name tells you nothing about potency, and potency in botanicals varies enormously with growing conditions, plant part and extraction method.

Also note the plant part. Root, leaf, seed and aerial parts are chemically different. Horse chestnut seed extract is the studied material; horse chestnut leaf is not.

5. Compare to the researched dose 📏

This is the step that separates a serious formula from a decorated one. Look up the dose used in human research for the one or two ingredients you actually care about, and see whether the label is in the same range or an order of magnitude below.

A useful shortcut: add the researched doses of the top three ingredients together. If the total exceeds what the serving size can physically hold, the formula is not delivering researched doses of all of them.

6. Read the other ingredients line 🧂

The “other ingredients” section lists capsule material, flow agents, fillers and colours. Most are harmless. What you are looking for is allergens, gelatin if you are vegetarian, and whether the list is longer than the active list — which occasionally tells its own story.

7. Check the guarantee and the seller 🔁

With a blend, the refund window is the only real protection you have. Note the length, whether it runs from purchase or delivery, whether opened bottles qualify, whether an RMA number is required, and who pays return shipping. Screenshot the terms on the day you buy, because vendors change them.

Five red flags that end the conversation 🚩

• “FDA approved.” No dietary supplement is FDA approved. A product claiming it is either ignorant or dishonest.
• Disease claims. “Treats,” “cures,” “reverses” anything. These are illegal for supplements and signal a seller who does not mind breaking rules.
• Fake scarcity. Countdown timers that reset, stock counters, “4 people are viewing this.”
• No physical address or contact route. If you cannot find who to send a return to, do not send them money.
• Reviews with no timeframe. A testimonial that does not say how long the person used it is decoration, not evidence.

Apply it to anything 🌿

Run these seven checks on the next bottle you pick up, including the ones we write about. Our ingredient page is structured around exactly this method: every botanical, the dose research used, and what the label discloses. On step two, that particular product scores badly — and saying so is the point of the exercise. ✅
