Luo San

Meet Luo Han Guo (Momordica charantia), often called the 'Longevity Fruit' or 'Monk Fruit.' Native to Southern China, this small, green gourd has been used for centuries in Traditional Chinese Medicine. Its claim to fame? A unique compound called mogrosides, which makes it up to 300 times sweeter than sugar—yet it has a **zero glycemic index**. It’s nature’s ultimate sweetener and a powerhouse of antioxidants, offering a way to satisfy a sweet tooth without the metabolic crash of refined sugar.

Health Benefits & Sources

Why You Need It

Supports Healthy Blood Sugar Levels: Unlike sugar, Luo Han Guo does not spike insulin, making it a safe alternative for diabetics.
Potent Antioxidant Power: Mogrosides fight oxidative stress, which protects cells from damage and aging.
Soothes Sore Throats & Coughs: A classic remedy in Chinese herbal medicine to reduce inflammation in the throat.
Anti-Inflammatory: May help lower systemic inflammation markers in the body.

Deep Dive

The magic lies in mogrosides. When you consume refined sugar, your blood glucose spikes, leading to energy crashes and inflammation. Luo Han Guo passes through the digestive system without being absorbed as a carbohydrate. Instead, the mogrosides act as antioxidants within the gut and bloodstream. Recent studies suggest these compounds may protect the liver and kidneys from oxidative damage, making this supplement a dual-purpose tool for both metabolic health and cellular protection.

Natural Food Sources

While the raw fruit is the source, you are unlikely to find the fresh gourd in a standard grocery store. It is most commonly processed into extracts.

Form	Preparation	Usage

Supplementation

Luo Han Guo is generally recognized as safe (GRAS) by the FDA. Because it is intensely sweet, a little goes a long way.

Dosage: There is no strict RDA. Start with a pinch of powder (approx. 10-50mg of extract) or one tea bag per cup of water.
Who should take it: Diabetics, low-carb dieters, or anyone looking to reduce sugar intake while enjoying sweetness.

Frequently Asked Questions

It is much sweeter than sugar (100-300x), but some high-quality extracts have a very slight, faint fruity aftertaste.

Yes! Mogrosides are heat-stable, unlike some other sweeteners that lose sweetness when baked.

No. It provides sweetness and energy without the jitters or crash associated with caffeine.

The extraction process to isolate the mogrosides is labor-intensive, and the fruit itself has a low yield of active compound.

Safety & Side Effects

Safety Profile: Generally considered very safe.

Side Effects: Extremely rare. In very high doses, some users report mild bloating or nausea due to the bulk of the supplement carrier (not the fruit itself).

Interactions: None known. It does not interact with insulin or common diabetes medications, but because it lowers blood sugar, monitor your levels if you are already on medication to avoid hypoglycemia (blood sugar dropping too low).

Who Should Avoid: No major contraindications, as it is not a stimulant like caffeine.
