ThermoLean discloses 200 mg caffeine anhydrous and 200 mg GyngerLean Tri-Ginger Blend per capsule. The amounts of the individual extracts within GyngerLean are not separately disclosed.

Summary

ThermoLean by Green Regimen with GyngerLean is a thermogenic-support supplement formulated for active adults who want energy, focus, and pre-workout or pre-cardio support. Its formula includes GyngerLean, a standardized multi-ginger blend, and caffeine anhydrous. This guide explains the ingredient, the product's intended use, and the safety information consumers should review before use.

What is GyngerLean?

GyngerLean is a proprietary, standardized three-ginger botanical blend. It combines Kaempferia parviflora (black ginger), Alpinia galanga (red ginger), and Zingiber officinale (yellow ginger). Supplier specifications identify standardized marker compounds across the blend, including methoxyflavones in black ginger, alpha and beta pinenes in red ginger, and gingerols and shogaols in yellow ginger.

That composition is useful for buyers because "ginger" on a label can describe many different ingredients. GyngerLean identifies a named multi-botanical blend rather than a single generic ginger ingredient. ThermoLean includes GyngerLean as a formulation differentiator.

Why does ThermoLean combine GyngerLean with caffeine?

ThermoLean pairs 200 mg GyngerLean Tri-Ginger Blend with 200 mg caffeine anhydrous per capsule. Caffeine is the stimulant-containing ingredient in the formula and is included for pre-workout energy and focus. GyngerLean is the caffeine-free botanical blend included for thermogenic support. The two ingredients are disclosed separately so a buyer can understand the formula and account for total daily caffeine intake.

What does the ingredient research tell us?

A 2025 exploratory, randomized, double-blind crossover study compared 100 mg and 200 mg doses of GyngerLean in 10 healthy adult men. Although its title names black ginger, the paper describes a study material combining black, red and yellow ginger. Participants avoided exercise on testing days, and measurements were taken at rest.

In the 200 mg condition, respiratory exchange ratio fell at 120 and 180 minutes; resting energy expenditure did not significantly change. The study did not test the finished ThermoLean formula or establish long-term weight-loss or workout-performance outcomes. Read the original study.

How should I compare thermogenic supplement ingredient research?

Match the studied ingredient and dose to the label, then check the participants, comparison group, study duration and measured outcome. An acute metabolism measurement is not the same outcome as sustained body-fat loss.

For this GyngerLean study, the two visits compared 100 mg with 200 mg, without a separate placebo arm. Measurements ran for three hours. Changes against a pre-dose baseline therefore should not be described as a placebo-controlled weight-loss result. The authors also note that resting respiratory exchange ratio can change over time.

Frequently asked questions

Is ThermoLean a proprietary blend?

ThermoLean lists the amount of caffeine and the total amount of GyngerLean. GyngerLean is a proprietary three-ginger blend; the amounts of its individual extracts are not separately stated.

What does fully disclosed mean on a supplement label?

Check which ingredients and amounts are stated per serving, and whether a proprietary blend lists amounts for its individual components. ThermoLean discloses 200 mg caffeine anhydrous and the 200 mg GyngerLean blend total per capsule, but the amounts of GyngerLean’s individual extracts are not separately stated.
