Polyglycerols

Polyglycerols are natural compounds formed when glycerol molecules link together. You find them abundant in plant foods and they are also used as safe food additives for texture. They play a vital role in how your body processes fats and maintaining cellular health.

Health Benefits & Sources

Why You Need It

Cellular Communication: Essential for building cell membranes.
Fat Metabolism: Helps the body process fats efficiently.
Hydration: Acts as a humectant to retain moisture.

Deep Dive

Polyglycerols are essentially chains of glycerol, a fundamental component of your body's triglycerides. When you eat plant-based fats, you are consuming these naturally. They are crucial for the structural integrity of every cell in your body, particularly in the brain and nervous system. While often used in supplements for hydration, their primary natural benefit is supporting healthy cellular function and energy production.

Natural Food Sources

Unlike synthetic additives found in processed foods, natural polyglycerols are best obtained through whole foods.

Food	Amount	% Daily Value
Olive Oil	1 tbsp	~8%
Avocado	1 medium	~6%
Spinach	1 cup cooked	~4%
Broccoli	1 cup cooked	~3%

Supplementation

Polyglycerols are rarely taken as a standalone supplement. They are usually found in Omega-3 supplements or Phospholipid complexes (like krill oil). If you eat a diet rich in healthy fats and vegetables, supplementation is usually unnecessary.

Top Food Sources

Olive Oil

Frequently Asked Questions

Not exactly. Glycerin is a single molecule (glycerol). Polyglycerols are chains of glycerin molecules linked together.

As emulsifiers, they help oil and water mix, keeping your skin hydrated and products stable.

From food sources, it is very difficult to overconsume. High doses from supplements may cause loose stools.

Yes. Natural polyglycerols are plant-derived. Synthetic versions are also vegan.

Safety & Side Effects

Polyglycerols derived from food sources are Generally Recognized As Safe (GRAS) by the FDA. There are no known toxicity levels for dietary intake. However, polyglycerol esters used in processed foods (like non-dairy creamers) may cause mild digestive upset (gas or bloating) in sensitive individuals if consumed in large quantities.
