Regular Periods & Ovulation
By restoring more normal insulin and ovarian function, inositol can support fertility, reduce excess androgens, and ease common PCOS symptoms such as irregular periods and acne. Vitamin B6 also contributes to the regulation of hormonal activity (proven health claim authorised by the EFSA and MHRA), an important factor for fertility and menstrual health in women managing PCOS.

Better Insulin Sensitivity
Inositol helps women with PCOS by improving the way their bodies respond to insulin, which can rebalance hormones involved in ovulation and menstrual cycles. Chromium contributes to the maintenance of normal blood glucose levels (proven health claim authorised by the EFSA and MHRA) which is essential for women with PCOS, as steady blood sugar supports insulin sensitivity and weight management.

Metabolism Support
Chromium contributes to normal macronutrient metabolism (proven health claim authorised by the EFSA and MHRA), helping your body process proteins, carbohydrates and fats efficiently for stable energy and a healthy metabolism.

Energy & Vitality
Vitamin B6 contributes to the reduction of tiredness and fatigue and supports normal energy-yielding metabolism (proven health claim authorised by the EFSA and MHRA), valuable if low energy is linked with hormonal imbalance.

Mind & Mood
Vitamin B6 contributes to normal psychological function and to the normal functioning of the nervous system (proven health claim authorised by the EFSA and MHRA), supporting mood balance and mental wellbeing, which can sometimes be affected in PCOS.

Storage
Keep out of direct sunlight in a cool, dry place. Keep out of reach of children. For best before end and batch number see base.

Cautions
Food supplements must not be used as a substitute for a varied diet and healthy lifestyle. If you are pregnant, lactating, taking medication, under medical supervision or under the age of 18 it is advisable to consult a GP prior to taking any supplements. Discontinue use and consult a GP if any adverse reactions occur. Do not exceed stated dose.

Chew, crush or swallow 4 tablets daily, two in the morning and two in the evening before food.

Whilst it’s safe to swallow these tablets whole, we strongly recommend that you chew them up first - they’re very big!

We recommend taking them with food, because that’s how to make sure you absorb as much as possible.

Consistency is key. Take your inositol every day for best results, as benefits build gradually with continued use. Keep taking the supplement throughout your cycle, including during your period, unless you are advised otherwise by a doctor or nutritionist.

As ovarian function begins to recover, cycles may temporarily become irregular – this can indicate that ovulation is restarting and hormone balance is improving, even if your period pattern seems less predictable at first.

If you are taking inositol to support egg quality, allow at least 90 days before trying to conceive, as this is the typical time needed for an oocyte to mature into a healthy egg ready for ovulation.

Pairing inositol with a balanced diet and regular exercise can further enhance insulin sensitivity and hormonal balance.

Warnings

If you’re on thyroid medication, medication for diabetes or insulin resistance, or fertility treatments, check with your GP before starting this supplement (or any other inositol supplement) to make sure your supplement routine is safely coordinated.

What is VitaBright Inositol Complex Good For?

Regular Periods & Ovulation

Inositol and vitamin B6 offer support for women's monthly cycles and the relief of pre-menstrual symptoms and dysmenorrhea, including for women with PCOS. Myo Inositol is lacking in the ovaries of women with PCOS and supplementing can restore regular ovulation and menstruation. Vitamin B6 contributes to the regulation of hormonal activity, making it equally supportive for women with PCOS.

Better Insulin Sensitivity

Correcting inositol deficiency can help tackle insulin resistance in women with PCOS, whilst chromium contributes to the maintenance of normal blood glucose levels - helpful for stable energy and weight management.

Metabolism and Weight Management

Chromium helps metabolise food - proteins, carbohydrates and fats - to use for energy and tissue repair. Many women with hormonal issues find it easier to manage their weight once they supplement with inositol for hormones and chromium for additional metabolic and blood sugar support.

Energy & Vitality

Vitamin B6 contributes to the reduction of tiredness and fatigue and supports normal energy-yielding metabolism, valuable if low energy is linked with hormonal imbalance.

Mind & Mood

Vitamin B6 contributes to normal psychological function and to the normal functioning of the nervous system, supporting mood balance and mental wellbeing, which can sometimes be affected in PCOS.

FAQs About Inositol and PCOS

Inositol Complex combines myo-inositol and D-chiro-inositol in the scientifically supported 40:1 ratio, along with key partner nutrients like Vitamin B6 and Chromium. It’s designed to support women with PCOS by promoting hormonal balance, healthy ovulation, improved insulin sensitivity and more regular menstrual cycles.

Polycystic Ovary Syndrome (PCOS) can show up differently in every woman, but common symptoms include irregular or missed periods, acne, oily skin, unwanted hair growth, thinning hair on the scalp, difficulty losing weight, and fertility challenges. Many women also experience signs of insulin resistance such as fatigue, sugar cravings, or weight gain around the abdomen.

PCOS is usually diagnosed using the Rotterdam criteria, which require two of the following three features: irregular or absent ovulation, higher levels of male hormones (androgens) or symptoms of them, and polycystic ovaries seen on ultrasound. Blood tests are often used to check hormone levels, insulin, and thyroid function, while doctors also look at your cycle history and physical symptoms.

Women with PCOS often have insulin resistance, which can disrupt ovulation and increase androgen levels. Inositol, particularly myo-inositol and D-chiro-inositol in a 40:1 ratio, helps improve insulin sensitivity, which in turn supports hormone balance, regular ovulation, and fertility. It’s one of the most researched natural options for PCOS-related hormonal and metabolic symptoms.

Not always, but many women benefit significantly. Inositol is most effective for those whose PCOS is linked to insulin resistance or metabolic imbalance — the most common subtype. Women with adrenal or inflammatory forms of PCOS may notice less impact on their cycle, though they may still experience improvements in mood, energy, or skin.

Many PCOS symptoms — like irregular periods, acne, and difficulty losing weight — are linked to insulin resistance and hormonal imbalance. Inositol helps cells respond more effectively to insulin, which can help reduce excess androgens and support normal ovulation. Vitamin B6 contributes to the regulation of hormonal activity, while Chromium helps maintain normal blood glucose levels, all working together to restore balance from within.

Every woman’s body is different, but most people notice improvements within 6 to 12 weeks of consistent use. Early changes often include steadier energy and mood, followed by more regular cycles and clearer signs of ovulation. Consistency is key — hormonal balance takes time to restore naturally.

Occasionally, yes — especially in the first month or two. As your hormones and insulin sensitivity start to adjust, your cycle may temporarily become shorter, longer or even skip. This is usually a sign that your ovaries are rebalancing. Most women find their cycles become more regular with continued use over time.

Inositol can still support healthy insulin sensitivity and blood sugar balance even in people without PCOS. It’s sometimes used alongside Chromium and B vitamins to help maintain steady energy levels, reduce sugar cravings, and support metabolic health — especially for those managing mild insulin resistance or blood sugar fluctuations.

Yes, inositol is a vital nutrient for men as well as women. In men, it supports insulin sensitivity, mood balance, and healthy sperm function. Myo-inositol is found in high concentrations in the testes and has been linked to sperm motility and fertility. It’s also used for general metabolic and nervous system support in both sexes.

Inositol is generally very well tolerated, but women who are pregnant, breastfeeding, or taking medication for blood sugar or thyroid conditions should check with their GP before starting. If you’re underweight, have very low blood sugar, or aren’t sure which type of PCOS you have, seek professional guidance to ensure it’s the right supplement for you.

Yes. It can be safely combined with most vitamins and minerals, including Vitamin D, Omega-3, and magnesium. Many people use it alongside a balanced diet and gentle exercise for the best results in managing PCOS symptoms.

Good so far
I’ve only been taking these for a month so far and haven’t seen a massive difference yet, I do feel my hunger is more under control now though. I don’t have PCOS but wanted to give these a try to see if they regulate my periods. So far I have also noticed a more stable BBT reading compared to other cycles, so fingers crossed they make me ovulate :) I’d say they are worth a shot!

Huge tablets, but already noticing a positive difference
This is my first time taking any kind of supplements to help manage PCOS symptoms. I have been taking these for about a few weeks now, although only once a day. My period has been a lot easier to deal with already (cramps, menstrual flow). But I did not give five stars as the tablets are huge. I first tried to break them in half and they sharply grazed down my throat... Swallowing them whole is less annoying.
