African Mango Seed Extract: What One Ten-Week Trial Found
One randomised trial, 102 overweight adults, 150 mg twice a day for ten weeks. What it measured, and what fourth place in a 200 mg blend allows.
The Glyco Harmony blog takes one line of the label at a time and follows it to the research: the African mango trial, the pooled ginseng figures, the licorice compound and the grapefruit extract in the blend, and how to read a 200 mg proprietary blend. Each post cites its sources inline and sets research doses beside the label.
Below: the five posts, the label line each one follows, and how the topics were chosen.

Each post runs 1,500 to 2,000 words, with a table, the label beside the research, and the sources listed at the foot.
One randomised trial, 102 overweight adults, 150 mg twice a day for ten weeks. What it measured, and what fourth place in a 200 mg blend allows.
Sixteen trials pooled, a 0.31 mmol/L difference in fasting glucose, and why the label names the aerial parts rather than the root.
A sweet compound from licorice root with a potassium and blood-pressure caution, and the readers who should ask before the first dropper.
Statins, blood-pressure drugs, and the other names on the same panel that carry a medicine note of their own.
What the federal rule requires of a blend, and the ceiling arithmetic its order of names allows, worked through for all 22.
Every topic comes from this bottle’s own panel, so each post can set the research beside a real label.

| African Mango Seed Extract: What One Ten-Week Trial Found | African Mango Seed Extract | 4th of 22 in the blend | One 2009 trial, 102 adults |
| Panax Ginseng Aerial Extract: What 16 Trials Say About Fasting Glucose | Panax Ginseng Aerial Extract | 12th of 22 in the blend | A 2014 meta-analysis of 16 trials |
| Monoammonium Glycyrrhizinate: The Licorice Compound in a Blood Sugar Drop | Monoammonium Glycyrrhizinate | 18th of 22 in the blend | A 2021 review and the NCCIH licorice page |
| Grapefruit Extract on a Supplement Label: What It Means for Your Medicines | Grapefruit Fruit Extract | 11th of 22 in the blend | The FDA grapefruit page |
| How to Read a 200 mg Proprietary Blend: 22 Names, One Number | Proprietary Blend 200 mg | Under the chromium line | 21 CFR 101.36 |
Three rules hold in every post.
Figures describe the posts themselves, not the product.
Every post starts from a line of the Glyco Harmony panel, from the fourth name in the blend to the blend’s own total, and stays with it.
Each study keeps its own dose, its own length and its own volunteers. A trial result never travels to the bottle.
Two of the five posts are about medicine notes: the licorice compound and the grapefruit extract. Both sit inside the same blend.
Three short references that every post leans on.
21 CFR 101.36 sets how a Supplement Facts panel declares a proprietary blend: a total weight, and the names in order of weight.
The FDA does not approve dietary supplements, or the structure-and-function wording they carry.
NCCIH advises raising any new supplement with a health care provider first, especially alongside a condition or a medicine.
