Eight named ingredients. Each one tagged for how strong the evidence genuinely is, not how good it sounds on a label.
A documented nutritional role or a well-characterised property, not inferred from a small study.
Genuine research interest exists, but studies are small, inconsistent, or both.
Long-standing traditional use, with modern research still at an early stage.
An essential trace mineral with an authorised role in normal macronutrient metabolism and in maintaining normal blood glucose levels. The most firmly established ingredient in the bottle, documented in the NIH Office of Dietary Supplements chromium fact sheet.
An Ayurvedic herb known as the “sugar destroyer” because chewing the leaf temporarily blunts the ability to taste sweetness. The ingredient most associated with sweet-craving support.
A West African fruit whose seed extract is rich in fibre and has been examined in small trials around appetite and metabolic markers. Early-stage evidence rather than settled.
Also called Siberian ginseng, a classical adaptogen with a long record in traditional practice for fatigue and endurance. The NCCIH Herbs at a Glance database is a good neutral place to check it.
One of the most widely studied botanicals in the world, examined for fatigue, cognition and glucose-related markers. Results are inconsistent across trials.
A cruciferous root cultivated above 4,000 metres in the Peruvian Andes, used for centuries to support energy and endurance. Modern research is early-stage.
A member of the mint family used in Ayurvedic practice, containing forskolin. Most published work is preclinical rather than large human trials.
An Amazonian plant with one of the highest natural caffeine contents of any botanical, included for alertness. This makes the product a caffeine-containing one, not a stimulant-free one.
If you take insulin, metformin, a sulfonylurea or any other diabetes medication, speak to your doctor before using this product. Several ingredients here are studied for glucose handling, and combining them with prescribed treatment can lower blood sugar further than intended.
This is not a formality — hypoglycaemia is a real risk, and your prescriber may want to monitor you more closely. The same caution applies to blood pressure and thyroid medication.
