Inositol is a natural carbohydrate and a vitamin-like compound (often called Vitamin B8, though not officially a vitamin). It supports cell signaling, fat metabolism, and nerve function.

Natural Sources:
Fruits (oranges, cantaloupes)
Whole grains and beans
Nuts and seeds
Animal organs (liver)
Commercial Sources:
Corn (main, cost-effective)
Rice bran or wheat bran (less common)

How Do We Test Inositol?

Testing depends on the application:
Microbial Method (Food):
Used for milk, cereals, and fruits.
We use Saccharomyces uvarum yeast. Its growth depends on Inositol.
We measure growth with a spectrophotometer and calculate content using a standard curve.
HPLC-MS/MS (High Precision):
Used for supplements and research.
It separates Inositol in a column and detects it with a mass spectrometer.
This method is fast, accurate, and requires minimal preparation.

Both methods are reliable. Choose based on your product.

Inositol Concentrations and Uses

Low (50%–70%):
Food and feed (drinks, yogurt, cereals).
Improves nutrition without affecting taste.
Medium (80%–95%):
Dietary supplements (capsules, powders).
Supports metabolism, hormones, and reproductive health.
Typical dose: 2000–4000 mg myo-inositol / 300–1200 mg DCI daily.
High (98%+):
Pharmaceutical and research use.
Ideal for lab studies and specialized formulations.

Solubility and Appearance

Solubility:
Highly soluble in water
