What is Solaray Myo + D-Chiro Inositol 40:1?

Solaray Myo + D-Chiro Inositol 40:1 is a supplement that delivers a total 2,050 mg of inositol for cellular support.* It’s formulated with two types of inositol: myo-inositol and D-chiro inositol at a 40:1 ratio, which has emerged as the standard for efficacy in scientific studies.

What is myo-inositol?

Inositol is a sugar-like compound that supports cellular health.* It comes in nine types and myo-inositol is the most common.

What is D-chiro inositol?

D-chiro inositol is a sugar-like compound that supports cellular health.*

Why are myo-inositol and D-chiro inositol often taken together?

These forms of inositol are often taken together because myo-inositol is readily available in foods like corn, beans, fruits, and nuts, but it’s very difficult to consume enough D-chiro inositol through diet alone. Therefore, D-chiro inositol is mainly synthesized in the body from myo-inositol. Because of this conversion process, myo-inositol controls the levels of D-chiro inositol within your cells. Combined supplements can help you maintain the optimal ratio of these two inositol forms; see question 5 for more information.

What does the 40:1 myo-inositol to D-chiro inositol ratio mean?

40:1 describes the relative amounts of myo-inositol and D-chiro inositol found in this supplement; it contains 40 times more myo-inositol than D-chiro inositol. 40:1 is the ratio of myo-Inositol to D-chiro inositol found in healthy plasma. In clinical studies, this ratio has emerged as the most effective for therapeutic use.

What is inositol used for in a women’s wellness routine?

Women of all ages use inositol supplements to support daily health and cellular health* Many women combine daily inositol supplements with a multivitamin and probiotic as part of a foundational stack. Women are also encouraged to include regular exercise, a nutritious diet, and stress management techniques as part of their overall wellness routine.

How does inositol support cellular wellness?

Inositol is a form of sugar that your body naturally processes to provide structure to your cells. Inositol is necessary for cellular function, including the development of cell membranes.

Is Solaray Myo + D-Chiro Inositol vegan, gluten-free, and made without soy?

Yes, Solaray Myo + D-Chiro Inositol is vegan, gluten free, and made without soy.

What should you look for in a myo-inositol and D-chiro inositol supplement?

Choose a supplement that contains a 40:1 ratio of myo-inositol to D-chiro inositol; this is the ratio found in healthy plasma and is considered the most effective for therapeutic applications. Look for a supplement that is made in a GMP certified facility with lab-verified ingredients that are tested for potency and purity. All Solaray products are made in our GMP certified facility in Utah using globally sourced ingredients that are triple-tested for identity, potency, and purity—including heavy metals, microbials, and contaminants. We verify raw materials ourselves to ensure what’s on the label is exactly what’s in the bottle.

Who should talk to a healthcare professional before taking inositol supplements?

Always ask your healthcare provider before starting a new supplement, especially if you are pregnant, nursing, or are on daily medications. If you’re taking prescription medications, consult your healthcare provider in advance to avoid any potential interactions.

Reviews

Potentially helpful for women’s health, especially during the postpartum and breastfeeding period, though I haven’t noticed any significant benefits yet.

"I haven’t noticed any significantchanges in anything since I started using this product couple weeks ago. I did a little research before using it and found out that myo-inositol is commonly used for women’s health. I’m especially interested in its potential benefits for postpartum and breastfeeding period. The instructions are straightforward and the capsules are easy to incorporate into my daily routine. As for texture, it’s just regular capsules. So far, I haven’t experienced any issues, and I’m hopeful that I will notice some benefits in the future with continued use."

Helps with acne and ovarian cyst

"I loved these vitamins! They were actually recommended to me initially buy a Chinese medicine specialist. She raved about these to help with my cystic acne and my ovarian cyst. It helped tremendously with clearing my skin. I can’t wait to keep taking them. I’ve been taking them for about a month now. "

— JenniferP (5/5)

They’re easy to swallow and don’t leave unpleasant or aftertaste. I also like the packaging— it keeps the capsules protected and makes them easy to store and organize. The bottle is convenient and doesn’t take up much space. Overall, I appreciate the quality, convenience, and consistency of this product. It’s easy to incorporate into my daily routine, and I am very satisfied with it."

New Go To

"I take this supplement for PCOS. This particular brand is cost effective and easy to take. It does not have a taste and leaves no after taste. I’ve been using it for a month now and have seen a decrease in appetite and balanced my hormones making my menstrual cycle more manageable."

— CarissaS (5/5)

Try for yourself

"I’m not sure how I feel about these. I don’t necessarily need my sugar regulated so that could be why I didn’t see a difference but I would suggest trying it out for yourself and see what you think. It seems to have good ingredients."

— SallyT (3/5)

Worth a shot!

"I have seen these pills on another website that sells items for pelvic floor therapy and have always wanted to try. I’ve been skeptical but what do I have to lose. I have PCOS and willing to try anything at this point. I like the ingredient list is pretty clean. A down side for me is that I have to take 4 capsules daily. I am not a pill person so 4 is quite a bit on top of my other required daily pills I need to take so remembering is hard. I have PCOS and endometriosis and so far so good. I haven’t been taking them for a solid 2 months yet so I can see a full benefit but since taking it, I have been seeing improvement in my acne. My mood has improved. Of course I’m waiting to see how my ovulation improves and if I can start tracking my cramping. I’m hopeful."

— AmyC (4/5)

Muy buenos resultados

"Highly recommended for women with SOP. It helps balance hormones, regulate your menstrual cycle, and improve insulin sensitivity. This particular supplement consists of four vegan capsules daily. Its main ingredient is myo-inositol, and it also contains D-chiro-inositol. It has no particular flavor. I've been using it for three weeks, and the results are very noticeable in my menstrual cycles and skin. Try it, consult your doctor, and let me know how it goes."

— KarilyA (5/5)

Hormonal balance

"I have been using the Solaray Myo + D-Chiro Inositol 40:1 supplement, and my experience has been very positive so far. The capsules are standard-sized, easy to swallow, and leave no unpleasant aftertaste. Since adding it to my daily routine, I have noticed a great improvement in my hormonal balance and overall energy levels throughout the day. It offers excellent value for the price considering the quality of ingredients."

— SaydysM (5/5)

Increased mood, decreased weight

"Though I don’t have polycystic ovarian disease or problems with my cycle since I have had a hysterectomy, I was happy to try this because since I had my hysterectomy, my energy levels have gone down, and my weight crept up a little bit. I was excited to try this and see how it could help. Four gelcaps a day and after about a week, I noticed my energy levels were improving and after the two weeks of taking it, I noticed I had already lost about a pound or so I’m hoping if I can with continued usage, I can continue having increased moves and energy and maybe see a little bit more weight off though scale overall I’m very happy with the results. I love that there’s no taste easy to take the gel caps, and no clumsy mixing of powders, and most of all I love that with the brand I know that the ingredients are 100% natural and come from a reputable company."

— DawnS (4/5)

Good supplement brand

"I recommend this supplement brand, they are consistently good quality. There is no smell for these particular capsules. I would recommend taking them with food as they can cause some stomach aches otherwise."
