Inositol (Women's Core Nutrient)

Inositol is a naturally-occuring, vitamin-like nutrient that helps support how your cells communicate — especially in pathways related to hormones, insulin signaling, and metabolic function. There are two main forms: myo-inositol, which supports hormone signaling, and d-chiro-inositol, which supports healthy glucose metabolism. In the body, these naturally exist in a 40:1 ratio, which is considered the most physiologically appropriate and well-researched proportion. Arrae Inositol uses this clinically studied 40:1 ratio to support both hormonal and metabolic health in a more aligned way.

Lactoferrin is a naturally occurring, foundational protein in the body that supports iron regulation, immune health, and gut balance by helping the body bind and use iron more efficiently. Lactoferrin is best known as the key bioactive component of colostrum, where it plays an important role in immune and gut support. While most lactoferrin on the market is bovine-derived, arrae Inositol uses Effera™ Lactoferrin. This bio-identical, fermentation-derived form mirrors human lactoferrin for better recognition, bioavailability, and digestive tolerance — without dairy or animal sources.

Take 1 arrae Inositol stick pack daily, with or without food. Dissolve gradually on your tongue, or mix into your favorite drink. For PCOS support, take 2 stick packs daily – ideally one in the morning and one in the evening, or as directed by your healthcare provider.

Consistent use is recommended for at least 3 months for best results.*

Hormones influence how you feel day to day — from energy and mood to cravings, skin, and cycle rhythm. Some women explore hormone support when they notice changes or challenges in these areas, while others choose to support their hormones proactively as part of a long-term wellness routine. That said, some key signs your hormones need support include:

• Irregular or inconsistent cycles
• Intense cravings, especially for sugar or carbohydrates
• Unexplained weight gain or difficulty losing weight
• Changes in energy levels or ongoing fatigue
• Mood changes or increased emotional sensitivity and stress 
• Difficulty maintaining metabolic balance or blood sugar control 
• Monthly breakouts or skin changes
• Unwanted hair growth or hair shedding

If you have a medical condition or are working with a healthcare provider on a specific hormonal concern, we recommend checking with them before adding any new supplement.

Yes! You do not need a diagnosis to benefit from arrae Inositol. It’s designed foundational nutrient for any woman who wants to support hormone and metabolic health daily systems that influence hormones, metabolism, energy, mood, and cycle rhythm — whether you’re responding to subtle changes or simply supporting long-term balance.

Yes! While 40:1 inositol is often associated with reproductive health, research shows its benefits extend into perimenopause and menopause. Particularly when taken twice daily, studies have shown it can be helpful in supporting metabolic changes that commonly occur during this stage of life including improvements in metabolic markers, insulin sensitivity and glucose metabolism. For this reason, some women in perimenopause choose to take Arrae Inositol once daily for foundational support, while others opt for twice-daily use for enhanced metabolic or hormonal support, depending on individual needs. 

Arrae Inositol goes beyond a standard inositol powder by combining clinically studied inositol with additional foundational nutrients designed to support women’s health more holistically. Key differences include:

• Clinically studied 40:1 inositol ratio (myo-inositol to D-chiro-inositol), which reflects the balance naturally found in the body and is widely used in women’s health research.
• IN401™ complex, which pairs inositol with Effera™ lactoferrin, a bio-identical precision fermented lactoferrin that supports gut health, iron regulation, and overall foundational wellness.
• Bioactive folate (Quatrefolic®) instead of folic acid, for optimal absorption and reproductive support. 
• Fast-melt stick pack format, designed for convenience, flexibility, and consistent daily use- no capsules or bulk powders required.

Folic acid is a synthetic form of vitamin B9 that must be converted by the body into its active form before it can be used. Not everyone converts folic acid efficiently, which can lead to unmet needs in some individuals. Arrae Inositol uses Quatrefolic®, a folate that is already in its active, bioavailable form, meaning it can be used directly by the body without additional conversion. This makes it a more reliable and effective option, especially for individuals with MTHFR gene variations or anyone seeking optimal folate utilization.
