THE FORMULA
What is inside LeanBurn Drops
Last updated: July 2026
LeanBurn Drops contains six actives in a liquid base: chromium, African mango seed extract, green tea leaf extract, guarana seed extract, maca root extract, and grape seed extract. The manufacturer lists all six by name and combines them as a proprietary blend, which means the label does not print how many milligrams of each one a dropperful delivers. That is the first thing you should know, and it is why the dosage column in the table below reads the way it does.
| Ingredient | Source | Dose per serving | Role in the blend |
|---|---|---|---|
| Chromium | Trace mineral | Not published | Contributes to normal macronutrient metabolism. The NIH fact sheet is the clearest public summary of what it does and where evidence is thin. [2] |
| African mango seed extract | Irvingia gabonensis | Not published | The best known botanical in this category. Used for appetite support; research is limited and mostly small in scale. |
| Green tea leaf extract | Camellia sinensis | Not published | Source of catechins and a modest amount of caffeine. Among the most studied plants in nutrition. [3] |
| Guarana seed extract | Paullinia cupana | Not published | Naturally caffeinated. This is the reason the label says morning rather than evening. [7] |
| Maca root extract | Lepidium meyenii | Not published | A traditional vitality botanical with its own research summary. Not a weight ingredient in itself. [6] |
| Grape seed extract | Vitis vinifera | Not published | Contributes polyphenols. A supporting player in the blend. |
Why the dosage column says "not published"
United States labelling rules allow a manufacturer to disclose a proprietary blend: the ingredients in descending order by weight, plus a single combined figure, without breaking out each component. Plenty of reputable products do it, usually to protect a formulation from being copied. It is legal and it is common. It is also, from a buyer's point of view, less information than you would like.
We had two options. We could publish plausible looking milligram figures the way a great many supplement sites do, or we could tell you the truth. We picked the truth, and it costs us conversions. If you compare LeanBurn Drops against a competitor whose site lists confident numbers, ask yourself whether those numbers appear on the physical label or only in the marketing copy. On our own reviews page, label transparency is the lowest scoring criterion we publish, at 3.9 out of 5, because that is what buyers actually rate it.
The six actives in plain language
Chromium
An essential trace mineral. Your body needs very little of it, and it participates in normal carbohydrate and fat metabolism. The NIH Office of Dietary Supplements maintains the definitive public fact sheet, including intake ranges and the state of the evidence on body composition, which is best described as mixed and modest.[2]
African mango seed extract
Irvingia gabonensis is a West African tree whose seed extract became a supplement staple in the 2010s. The research base is real but small, with trials that are generally short and modest in size. It sits in this formula for appetite support, and expectations should be set accordingly. The NIH weight loss supplement overview is the right context to read it in.[1]
Green tea leaf extract
Green tea contributes catechins and a modest amount of caffeine. It is genuinely well studied, and both NCCIH and the Harvard Nutrition Source publish careful summaries covering benefits, limits, and the liver safety signal associated with high dose concentrated extracts.[3] [4] If you already drink several cups a day, factor that in.
Guarana seed extract
A South American climbing plant whose seeds carry naturally occurring caffeine, typically at a higher concentration by weight than coffee beans. It provides the alert edge in the blend.[7] If you are caffeine sensitive, this and the green tea are the two ingredients to weigh before ordering.
Maca root extract
A Peruvian root vegetable used traditionally as a general vitality food, with a research summary of its own.[6] It is not a fat burning ingredient and we are not going to present it as one. It rounds the formula out.
Grape seed extract
A polyphenol source, most often discussed for antioxidant activity. A supporting ingredient rather than a headline one.
How to take it
One to two dropperfuls daily, in the morning, ideally before a meal. Squeeze the bulb, place the liquid directly in your mouth, hold it briefly, and swallow. There is no need for water and no capsule to break down. Shake the bottle before use. Store it out of direct sunlight and keep the cap sealed. A 2 fl oz bottle works out at roughly a 30 day supply at the standard serving.
Because of the guarana and green tea, take it early. Buyers who take it after lunch are the ones most likely to mention disturbed sleep, and that is an easy problem to avoid.
Who should not take it
Do not take LeanBurn Drops if you are pregnant or nursing. If you are under 18, taking prescription medication, managing a diagnosed condition, sensitive to caffeine, or scheduled for surgery, speak with your clinician before you start. Chromium in particular is worth discussing if you take medication affecting blood sugar. Stop and seek advice if you have an adverse reaction. None of this is unusual advice for a caffeinated botanical supplement, and all of it is worth following.
Storing it, and how long a bottle lasts
Keep the bottle upright, capped, and out of direct sunlight. A kitchen cupboard is fine; a windowsill above a radiator is not. Botanical extracts in a liquid base are more sensitive to heat and light than a capsule is, which is the one genuine handling disadvantage of this format. Do not decant it into another container, and do not use it past the date printed on the label.
At one dropperful a day a 2 fl oz bottle runs a little over a month. At two dropperfuls it is closer to three weeks. Most buyers settle on one in the morning and move to two only if they are not noticing anything after a fortnight. That is a sensible way to do it, and it is why the packages are described in day supply terms rather than in bottles alone.
What the liquid base contains besides the actives
A liquid supplement needs a carrier and a preservation system, or it spoils. That means the bottle holds more than six ingredients in total even though six are the actives, and the remainder appear in the other ingredients line on the label rather than in the blend. This is normal, it is disclosed, and it is worth understanding so that the ingredient count on the front of a bottle is never mistaken for the full contents of the bottle. Read the whole label, not just the headline.
