Switch Nutrition Inositol 40:1 MYO : D-Chiro Inositol is an unflavoured powder combining two forms of inositol in a 40:1 ratio. It suits adults comparing a combined formula with products that list only one inositol form. Choose between the 150g and 300g tub options using the size selector. Both pack labels state the same ratio and a 1g serving size, so the difference between these options is the quantity of powder.
The 40:1 figure describes the relative proportions of myo-inositol and D-chiro inositol within the formula. It is separate from the amount in a measured portion. Each labelled 1g portion contains 1000mg of the combined inositol formula. Keeping those details separate helps when another product lists a different ratio, uses only myo-inositol or comes in capsules. A ratio alone does not tell you the serving size or the amount to use.
At the labelled 1g portion, the 150g tub supplies 150 serves and the 300g tub supplies 300 serves. The larger option contains twice the powder; it is not a stronger ratio or a larger labelled scoop. If you already use the formula and want fewer repeat purchases, compare the price per gram between the two sizes. The smaller tub may fit a preference for purchasing less powder at a time. Serving counts describe pack quantity rather than a fixed number of days.
The unflavoured format leaves you free to choose the drink you mix it with, rather than committing to a fruit or dessert flavour. For help comparing formula types, read our myo-inositol and D-chiro guide. It explains the label distinctions to consider alongside the ratio, serving size and pack quantity. You can also browse the Switch Nutrition range. Full ingredients, directions and pack-specific storage details stay in their dedicated tabs.
Product FAQs
What does the 40:1 ratio describe?
It describes the relative proportions of myo-inositol and D-chiro inositol in this formula. It is not a scoop size, mixing instruction or daily dose. The labelled serving size is 1g, containing 1000mg of the combined formula.
How do the 150g and 300g sizes differ?
They use the same 40:1 formula and the same labelled 1g serving size. The 150g option supplies 150 portions; the 300g option supplies 300. Choose the size in the selector and compare price per gram, rather than assuming the larger tub is a stronger formulation.
Is this myo-inositol alone?
This formula combines myo-inositol and D-chiro inositol. If you are comparing it with a myo-only product, look at the forms listed as well as the amount per serve. Our inositol formula guide explains these label differences.
Does it have an added flavour?
Switch describes the powder as unflavoured. The manufacturer suggests mixing it into water or another drink, giving you a choice of base beverage. Unflavoured describes the product format; it does not promise that every drink will have an identical taste or texture after mixing.
Do 150 or 300 serves mean that many days of use?
These figures count the labelled 1g portions in each tub. The number of days depends on the directions followed. Use the instructions on your physical pack and the Directions tab rather than treating a front-of-pack serving count as a daily-use schedule.
What should I check when comparing another inositol product?
Compare the inositol forms, ratio, amount per serve, powder or capsule format and total pack quantity. These details help you compare like quantities. The myo-inositol and D-chiro guide provides a starting point; each product’s own label determines its formula and use instructions.
