Polyglycerol

Polyglycerol is a natural plant-derived compound formed by linking together glycerol molecules. You might know it as a safe food additive (E475), but it's also naturally present in small amounts in healthy foods like honey and fermented vegetables. It acts as a powerful humectant (keeps things moist) and emulsifier. In the body, it functions similarly to healthy dietary fats, providing energy and supporting the absorption of fat-soluble vitamins. It is considered a 'slow-release' fat, which may help manage cholesterol levels and digestive comfort compared to standard fats.

Health Benefits & Sources

Why You Need It

Heart Health Support: Unlike some saturated fats, polyglycerol esters have been shown to help lower LDL (bad) cholesterol while maintaining HDL (good) cholesterol.
Sustained Energy: It provides a steady source of energy without the sharp spikes in blood sugar associated with simple carbohydrates.
Digestive Ease: It is easily digested and helps bind water in the gut, which can support smoother digestion and prevent constipation.

Deep Dive

Polyglycerol is technically a 'polyol'—a molecule with multiple alcohol groups. When consumed, your body breaks it down similarly to other fatty acids. The unique structure of polyglycerol allows it to interfere with the body's production of cholesterol in the liver, leading to better lipid profiles. Because it holds water so well, it also acts as a prebiotic of sorts, feeding beneficial gut bacteria and keeping the intestinal lining hydrated and healthy.

Natural Food Sources

While concentrated polyglycerol is often used in supplements, you can find it naturally in the following foods:

Food	Amount	% DV
Honey (Raw)	~150mg per 100g	2%
Soybeans (Fermented)	~80mg per 100g	1%
Cocoa Powder	~50mg per 100g	<1%
Olive Oil	~30mg per 100g	<1%
Wheat Germ	~25mg per 100g	<1%

Supplementation

Dosage: There is no official Recommended Dietary Allowance (RDA) for polyglycerol. In clinical studies involving polyglycerol esters, doses of 5 to 10 grams per day are typically used to observe cholesterol-lowering effects.

Who Should Take It:

Individuals looking to improve their lipid profile (cholesterol).
People seeking plant-based emulsifiers for digestive health.
Those on a plant-focused diet who want to maximize nutrient absorption.

Frequently Asked Questions

No. Polyglycerol is made from glycerol (a natural component of fats). Propylene Glycol is a synthetic chemical used in antifreeze. They are chemically distinct and have very different safety profiles.

Yes. Polyglycerol is a fat molecule, not a carbohydrate. It has a negligible impact on insulin levels and fits well into ketogenic macros.

It prevents the cocoa butter from separating from the cocoa solids (blooming), keeping the chocolate smooth and shelf-stable without using dairy.

For general health, yes. However, if you are taking it specifically to lower cholesterol, you would likely need to use a concentrated supplement or consume large amounts of specific foods like fermented soy.

Safety & Side Effects

Safety Profile

Polyglycerol is classified as Generally Recognized As Safe (GRAS) by the FDA and by the European Food Safety Authority (EFSA).

Side Effects: At normal dietary or supplemental doses (under 15g/day), side effects are rare. Consuming very high amounts (above 20g) may cause mild gastrointestinal upset, such as gas or bloating, due to fermentation by gut bacteria.
Interactions: There are no known severe drug interactions. However, because it can lower cholesterol slightly, monitor levels if you are taking statins to avoid cholesterol dropping too low.
Chemical Nature: While often used as an industrial emulsifier, food-grade polyglycerol is pure and free of harmful solvents. It is safe for vegans and gluten-free individuals.
