Craving crusher!

After about two weeks taking this, I have almost no cravings for sugary food nor do I want to eat in excess anymore! This was such a problem for me before I started this. I’ve lost a few pounds as well. My energy levels have increased a bit, too! So far so good.

Great product, quality, and results.

Easy to swallow, quality product, no gross taste or after-burps. I'm on my third month and through lifestyle change and the addition of supplements (this one among others), I have had wonderful weight-loss success! I will keep ordering again and again! 10/10

Helps with mood swings and maybe weight loss

The bottle was delivered on 25th and I started taking the supplement 2 pills with breakfast on 27th of June. I have been exercising 30-40 minutes a day and eating low carb diet since 3 weeks. My weight kept fluctuating around 84 kgs. But since I have started taking this supplement with my exercise and diet, I have started seeing reduction in my weight this week. I measure my weight every day at the same time. I will keep updating this review after couple of weeks maybe. I definitely feel like the pills are helping me. P.S. I know one week is too early to write a review but I have been exercising and maintaining low carb high protein and high fiber diet for about 3-4 weeks now. And today was the day I saw a significant reduction compared to past few weeks.

Made a Difference

I've waited to write a review--I read that effects can take 1-3 months depending on the person so since I'm finishing my third month I thought I'd update. My eating habits had tanked during the pandemic and it seemed all I wanted was high fat and high sugar foods. My cravings significantly decreased after taking this. I have lost weight but I think that is more a combination of calorie deficit, increased protein, and more tailored workouts. Overall I think this was the catalyst though, because I was/am no longer eating as bad as I was.

Balance to my life

I didn’t have any expectations when I started taken these. What I’ve found is that my urge to binge, to eat sweets and fats, has been dramatically reduced. I’ve been on these for two months and I will definitely continue.

Learn the basics

What is inositol?

Inositol is a sugar-like molecule found in every cell of your body. It has the same chemical formula as glucose, C6H12O6, but a different structure. It was long counted as a B vitamin, but its status as a vitamin is uncertain. There are nine forms of inositol. Myo-inositol is the most common one.

1 Your body is full of it.

Every cell in your body has it.

2 Here is where it goes.

Cells build it into their outer membrane.

3 This is why it matters.

Cells use it to pass messages along.

What does it do in the body?

Cells use inositol as a building block. It becomes part of molecules in the cell membrane that carry messages from outside the cell to the inside. Cells use these messages to respond to signals from outside the cell. Scientists call these molecules inositol phosphates and phosphoinositides. They belong to the "second messenger" systems cells use to relay signals.

Does your body make it?

Yes. Your cells make inositol from glucose. You also get some from food. The amount depends on what you eat. Fruits, beans, grains and nuts have the most. In grains and beans much of it is stored as phytic acid.

What are myo- and D-chiro-inositol?

They are two forms of inositol. Myo-inositol is the most common form in the body. Animal studies show that tissues can turn some of it into D-chiro-inositol. In one animal study, the share differed from tissue to tissue. Researchers study each form alone and the two together.

What is a 40:1 ratio?

Our formula has 2,000 mg of myo-inositol and 50 mg of D-chiro-inositol: 40 parts to 1. A ratio compares the two forms. See the Supplement Facts for the exact amount of each.

How is it taken?

Follow the suggested use on the label. Read the caution on the label before you use it. Talk with your healthcare provider if you are pregnant, breastfeeding, have a medical condition or take medication.

Supplements you can trust.

The FDA does not test supplements before they are sold. So we ask independent groups to test ours, and we show you how to look each result up yourself.

Clean Label Project Purity AwardClean Label Project says this product tested in the best one-third of its category for the contaminants it screens.

What it checks

  • Clean Label Project buys top-selling products in a category and has independent labs test them for heavy metals, pesticides, glyphosate, phthalates and bisphenols.

  • Clean Label Project judges each product on its own against limits set by product type.
  • Clean Label Project says certified products are tested again every year.

Why Wholesome Story?

We've been making inositol since 2017, and 1.25 million customers have made us part of their routine. Our Myo & D-Chiro Inositol is third-party tested, NSF Contents Certified, NSF Certified Gluten-Free, and Clean Label Project Certified, and we've held the Clean Label Project Purity Award for six consecutive years.

Every serving gives you 2,000 mg Myo-Inositol and 50 mg D-Chiro Inositol in a 40:1 ratio, and it's backed by our 90-day money-back guarantee.

Is taking inositol right for me?

Our Myo & D-Chiro Inositol is made for adults who want daily hormone support.*

Every body is different. When you start any new supplement, and especially if you have a health concern, talk with your healthcare provider, since we can't give medical advice.

Our 40:1 formula was made with women in mind. Men may prefer our Inositol (Myo-Inositol), which has no D-Chiro Inositol.

What's the difference between Myo-Inositol and D-Chiro Inositol?

Myo-Inositol is the most abundant form of inositol in the body. It helps cells respond to hormone signals, including the ones involved in healthy ovarian function.* D-Chiro Inositol is made by the body from Myo-Inositol and works alongside it for hormone support.*

Our formula is a 40:1 ratio of Myo- and D-Chiro Inositol, designed to support hormone signaling and a normal, healthy cycle at the cellular level.* Each serving pairs 2,000 mg Myo-Inositol with 50 mg D-Chiro Inositol.

Does this product contain hormones?

No. Our inositol doesn't contain any hormones. It supports the natural processes your body already uses, without supplying hormones directly.*

How and when should I take inositol?

Capsules: Use 1 serving (4 capsules), up to twice a day or as directed by a physician.

Powder: Mix 1 heaping scoop (2.2 g) into any hot or cold beverage that is free of caffeine, sugar substitutes, or carbonation. Do not mix with alcoholic beverages. Use 1-2 servings as needed or as directed by a physician.

Pick a time of day you'll remember, since consistency matters most.

Some customers take more or less than this based on their healthcare provider's instructions. If you'd rather not swallow capsules, you can open them and mix the powder into water. Your body processes it the same way. Or you can simply choose our powder.

How long should I take it?

Everyone's different. We recommend 3 to 6 months of consistent daily use.*

How long you keep taking it depends on why you're taking it, so it's best to decide that with your healthcare provider.

Can I take inositol with my other supplements and medications?

Please use caution when taking this product alongside any other supplement or medication that can lower blood sugar levels, as this combination may increase the risk of hypoglycemia.

Talk with your healthcare provider before adding it, especially if you take prescription medication. They can help determine whether it's right for you based on your individual health needs.

Can I take it if I'm pregnant or breastfeeding?

Talk with your healthcare provider if you are pregnant, breastfeeding, have a medical condition or take medication. Please read this before you use it: Consult your healthcare provider before use if you are contemplating pregnancy, pregnant, nursing, have any medical conditions, or use any medications.

Can I trust the quality?

Yes. Our Myo & D-Chiro Inositol is third-party tested, NSF Contents Certified, NSF Certified Gluten-Free, and Clean Label Project Certified, and we've held the Clean Label Project Purity Award for six consecutive years. Each mark links to its public listing in the certifications section above.

It contains no animal products, gluten, soy, or nuts. It's made in a facility that also processes common food allergens, so we can't promise the complete absence of any allergen not listed on the label. Our inositol is currently sourced from corn.

Is there a difference between the capsules and the powder?

Both have 2,000 mg Myo-Inositol and 50 mg D-Chiro Inositol per serving. Capsules are easy on the go, and the mix-in powder is an option if you'd rather not take or swallow pills. The capsules are made from hypromellose, a plant-based vegetarian capsule, and have a very small amount of rice flour to keep the powder flowing in the encapsulation machines.

Why aren't my capsules 100% full?

The density of the powder can vary from batch to batch because of particle size, so some capsules may not look completely full. Each one still has the right amount of active ingredients by weight, which is the most accurate way to measure. We didn't want to add fillers to make the capsules look full.

Can I save money by buying a bigger size?

Yes. The 3-month size costs about $0.78 a day, compared with $0.93 a day for the 1-month size, which is about 17% less per serving. Subscribing saves another 10%, and your first subscription order is $5 off. Pick the length that matches how long you plan to take it.

How big are the capsules?

Our Myo & D-Chiro Inositol capsule is size 0, 0.84 inches by 0.29 inches, about as long as a US nickel is wide. One serving is 4 capsules. If you prefer not to swallow capsules, you can open them and mix the powder into water, or choose our powder.
