Supplement Description

What is Inositol?

Inositol is a water-soluble compound that is closely associated with the B vitamin group. It is a carbohydrate which has been found to have a sweetness taste half that of sucrose (sugar).

Why take Inositol?

Inositol has long been known for its effects on the metabolism of the human body, where it plays its part in the synthesis of secondary messengers within our body cells. It is an essential component of the phospholipids that make up cellular membranes and is found in virtually every cell in the body.  It assists in the transmission of nerve signals, and helps to transport lipids within the body.  In recent years has been studied extensively in relation to its role in insulin signalling.  Supplementation has become popular and it is now widely recommended by practitioners, particularly for those with Polycystic Ovary Syndrome (PCOS).

Manufactured using high grade myo-inositol

Our capsules contain only myo-Inositol as opposed to D-chiro-inositol.  They each contain 500mg of myo-Inositol, are UK-made, easy to swallow, taste-free and a fully vegetarian and vegan capsule.

Food sources of Inositol

Foods containing the highest concentrations of myo-Inositol include fruits, beans, grains and nuts, however in grains this is in a non-available form called phytate. The more bioavailable form of Inositol comes from lecithin.

Review Details
Didn’t notice anything from using this
Service rating: Fantastic service, easy to order and quick delivery.
Product: I have thyroid issue's so I was hoping these would help.
Service rating: East website to navigate and delivery was reasonable and very quick!
Product: I’ve recently be diagnosed with PCOS, 7 years of irregular periods. Most recently I had gone 4 months without a period. Having read about this supplement on facebook PCOS support groups I thought I’d give it a go. After 2 weeks of taking just 1g a day I got a period! I’ve started tracking again on the Flo app and I’ve just had my 2nd period - I think these capsules have really helped so I would really recommend to any other PCOS girlies to try if they’re struggling with regulating periods. I’m now keeping my fingers crossed that these caps continue to work!
Service rating: I found your Website by Googling Myo Inositol supplements and found that your advertising of the product and detail and quality of the product most appealing.
Delivery Service is also super fast which is most impressive!
Product: In taking this for bringing down my anxiety from OCD. I've read lots of research for Myo Inositol to be helpful for OCD.
Service rating: Like the pouch packets. This product is working well for me and ordering experience was smooth with prompt delivery. No issues.
Product: Really helping my PCOS symptoms- total life changer. No adverse effects sleeping better not feeling as tired and hungry all the time.
Finally got my periods back and feeling like myself again!

Service rating: Easy process to order from them and item arrived quickly with minimal packaging. Will definitely order again
Product: I ordered these as an alternative to Metformin which I didnt like the side effects of. These are definitely better and working for my PCOS symptoms and helped me lose weight. The only downside is mild acne around my chin but nothing too drastic. The benefits outweigh this and it seems to have settled after a month of taking it.

Product: I'm taking it for my hormonal issues. It has only been a month since I started taking it. I've seen a difference in my acne.
Good price, especially as it includes postage. Downside is slow delivery and no tracking so best ordered when you’re not in urgent need.

Service rating: Great service, website is easy to use and the product is delivered so fast! My products are delivered through the letter box so it was perfect. Really recommend, no complaints here!
Product: I started using myo inositol to treat PCOS symptoms after coming off hormonal contraception which had been causing anxiety for many years. Other products I have tried upset my stomach but these are really great. Started seeing results after 3 months (at a higher dose than recommended on the packet, but that's at your own risk/do your own background reading) Periods are now fairly normal in cycle length and my hormonal acne drastically improved. And i have seen an improvement in my blood glucose levels although this is combination with better diet choices. The packaging is fully compostable which I love and I've already recommended it to several people who would like to come off hormonal contraception but have PCOS.
Service rating: Very fast delivery, great product, great price.
