Inositol Life

What is it?

Inositol is a naturally occurring carbohydrate compound found in the body, structurally similar to glucose. The body can produce inositol on its own, primarily in the kidneys, but it is also obtained externally from foods like fruits, beans, grains, and nuts.

Inositol exists in several forms, with myo-inositol being the most abundant. The 40:1 ratio of myo-inositol to D-chiro-inositol mirrors the body’s natural balance.

How it works

Insulin, the hormone that regulates blood glucose levels, relies on inositol compounds to communicate effectively with cells. Myo-inositol acts as a second messenger, amplifying insulin’s signal, promoting glucose uptake into cells. D-chiro-inositol works to convert glucose into glycogen (stored energy), further supporting blood glucose.

Myo-inositol plays a role in the brain’s production of serotonin, a precursor to melatonin, the hormone that regulates sleep-wake cycles. By promoting serotonin production, inositol supports melatonin production, leading to improved sleep quality and better circadian rhythm regulation.

In women, Inositol influences the function of follicle-stimulating hormone (FSH) and luteinizing hormone (LH), which play roles in ovulation and menstrual cycle regulation. Myo-inositol is critical for follicle health and maturation, supporting estrogen production.

Why is it important?

Optimal inositol levels aid in insulin sensitivity and efficient glucose metabolism, which is particularly important for those with insulin resistance or elevated blood sugar levels. Impaired insulin signalling increases the risk of metabolic conditions.

Adequate serotonin and melatonin levels are key for restful sleep. A deficiency in serotonin, often caused by stress or poor insulin regulation, impairs melatonin production, leading to poor sleep quality.

Healthy hormonal function supports balanced insulin and reproductive hormone levels. Impaired insulin sensitivity due to metabolic conditions or hormonal imbalances (such as PCOS) can lead to weight gain, irregular cycles, and fertility issues.

Inositol and longevity

As we age, insulin sensitivity, hormonal balance, and neurotransmitter regulation can decline, leading to blood sugar fluctuations, disrupted sleep, and hormonal imbalances. By supporting these essential functions, inositol may help improve metabolic health and sleep quality, as well as promote balanced hormone levels—all of which contribute to long-term health.

Is Inositol right for you?

Consider the following statements. If you find one or more relatable, Advanced Inositol might be the support you’ve been searching for:

  • I’m looking for a natural approach to support healthy blood sugar levels and improve insulin sensitivity.
  • Balancing my hormones is important, especially for managing PCOS or other hormonal issues naturally.
  • I’m interested in supplements that support mood, relaxation, and sleep, especially those that influence neurotransmitters like serotonin and GABA.
  • I heard Andrew Huberman say that a low dose of inositol is effective in supporting healthy sleep. 
  • I have PCOS and am looking to support my hormones; I’ve read that inositol may be able to help with my condition. 
  • I want to enhance my fertility and have read on Pubmed that inositol may support a healthy fertility protocol.
  • My doctor recommended Inositol to me for one or more of the above reasons.

Certainty of purity.

We are committed to the following quality controls to ensure consistency, reliability, and transparency in every product. Our goal is to raise industry standards and give you clear reasons to trust what you’re taking.

All products are made to cGMP (current Good Manufacturing Practice) standards, the global benchmark for supplement quality. GMP standards ensure strict control over how our supplements are produced, covering everything from cleanliness to documentation and quality control. Every step is monitored to guarantee consistency and safety in every batch, so you receive the same high-quality product every time.

Created by the US FDA, GMP regulations legally require manufacturers to ensure product safety, purity, and effectiveness. GMP minimises contamination, mix-ups, and errors, protecting consumers from ineffective or unsafe products.

GMP Guidelines Overview:

  • Manufacturing facilities must maintain a clean, hygienic environment in all areas, including labs and storage.
  • Facility design, operations, and environmental conditions must prevent cross-contamination of drug products and materials.
  • Manufacturing processes must be clearly defined, validated, and controlled to ensure consistency and compliance. Any process changes are evaluated for patient safety and product quality, with necessary validation.
  • Instructions and procedures must be written clearly and unambiguously.
  • Operators must be trained to follow approved procedures for production and control.
  • Records should be kept during manufacturing and quality control to confirm that all required steps and quality standards were met.
  • Discrepancies are investigated and documented.
  • Processes should remain controlled throughout the product life cycle, with improvements as needed.
    Records of manufacturing and distribution must be retained in an accessible format to trace the complete batch history.

At the foundation of what we offer is certainty of product quality through consistent third-party testing, specifically for purity.

In an industry where many supplement providers cannot be fully certain of their product quality, third-party testing is essential to ensure purity and safety. This process removes uncertainty, so you can be confident that you’re taking supplements that are both safe and effective.

Every active ingredient in every batch of vitalityPRO products is independently tested by accredited laboratories to ensure unbiased analysis of purity.

Additional third-party testing screens for contaminants such as heavy metals, pesticides, and microbes, ensuring that each product is safe for consumption. Although certificates are provided by the manufacturer, this independent validation goes beyond standard testing, adding an extra layer of quality control.

Independent third-party testing ensures that you receive reliable, high-quality products every time.

ISO 9001:2015 standards are an internationally recognised framework for effective quality management. This accreditation means we follow a structured system of continuous improvement, always refining our processes to enhance product consistency and customer satisfaction. ISO accreditation ensures that every aspect of our operations—from production to customer service—is optimised. This means better oversight, reduced risk of errors, and a clear focus on delivering consistent results.

Key Components of ISO 9001:2015

  • Customer Focus: Meeting and exceeding customer needs and expectations.
  • Leadership: Clear quality objectives and accountability at all levels.
  • Engagement of People: Involving employees in quality management.
  • Process Approach: Streamlining processes for efficiency and consistency.
  • Continuous Improvement: Regularly assessing and enhancing performance.
  • Evidence-Based Decisions: Actions based on data and analysis.
  • Relationship Management: Building effective relationships with key stakeholders.

Implementing and Maintaining ISO 9001:2015

  • Gap Analysis: Assessing current processes against ISO standards to identify needed improvements.
  • Documentation and Process Development: Aligning processes, roles, and quality metrics with ISO guidelines.
  • Employee Training: Ensuring all employees understand and follow quality management requirements.
  • Internal Audits and Management Reviews: Regular audits to assess quality management effectiveness and address issues.
  • External Audit for Accreditation: ISO-accredited body evaluates compliance.
  • Ongoing Improvement and Re-Certification: Continual assessment and re-certification to maintain high standards.

ISO 9001:2015 accreditation highlights a commitment to quality, customer satisfaction, and continuous improvement.

We believe you should have full clarity about what you’re putting in your body and the steps we take to ensure the quality of our supplements. That’s why we are transparent and open about every part of our process.

Transparency means we share all the details that matter—how our products are made, tested, and verified. From publishing third-party test results to offering clear ingredient labels, we provide you with the information you need to make informed choices about your supplements. Nothing is hidden, and every product comes with full accountability.

Frequently Asked Questions

Advanced Inositol can be taken by men. Both Myo and D-Chiro Inositol have been studied to improve the following parameters of men’s health:

– Sperm quality and motility
– Emotional health
– Blood sugar stability
– Sleep quality

Advanced Inositol may, as part of a holistic protocol, assist in treating the symptoms of PCOS by regulating the hormones involved in the menstrual cycle and by improving insulin sensitivity.

If you are using Advanced Inositol to improve your sleep, you will likely notice the results the same night you take the supplement.

For fertility issues and PCOS, it may take up to three months to start noticing an improvement.

Although inositol is sometimes called Vitamin B8, it is not actually a B vitamin. Unlike essential B vitamins, which must be obtained through diet, inositol is not considered essential because the body can produce it on its own, even though it shares some similarities with B vitamins.
