Customer Reviews

I purchased this product for a family member to help with their anxiety and symptoms of OCD. Bulk Supplement's Inositol is odorless, mixes well in liquids and has a mild sweet taste. After using it for a few weeks, we have noticed an overall better mood, and a significant decrease in anxiety. OCD symptoms have improved slightly, and as we slowly increase the dose, we hope to see more progress in that area as well! I highly recommend this product.*

Works for Anxiety
Inositol is an amazing nutrient. I use it for anxiety everyday. It's easy to mix in a smoothie as it tastes naturally sweet. It also boasts other benefits. I have never had any issue with it.*

Thank you, Bulk Supplements
I received this product in exchange for a review. I used the inositol as another B Vitamin and made up my own B Complex formula. I multiplied the dosage by 100 and it allowed me to put one gram of the inositol in the mix. When I finished with the formula, I weighed out the whole mixture, divided it by 100, and weighed out that much. We add it to fruit juice and noticed on Day One a greater sense of energy and wellness.
Thank you for your products!*

Inositol Newbie
Decided to give Inositol a chance and ordered from Bulk supplements a try after seeing a youtube video that showed inositol powder. I must say that after 4 days of using this powder my anxiety and panic attacks have decreased significantly. The taste is not bad and its easy to drink. I am really excited to at one point say that this supplement cured my mental health. So far so good. :) *

Loooooove this product

The Miracle supplement
This stuff is great. Wife and I have been using it for a while for many things. mostly keeping sperm count up and insulin regulation for me and egg quality and insulin regulation for wife. We are TTC for our 3rd child) She is PCOS and diabetic. This helps her PCOS, Regulates insulin naturally so she Is not taking diabetic meds any longer. This helps with many different things. Some of which are...

* Insulin regulation
* Support higher sperm count
* Depression

and the list goes on. These are the things that we have personally used it for and can attest to.

PCOS minimum 2g twice per day

Insulin regulation will very but found it to work well at 2g+ twice per day

Sperm count support minimum 1g twice per day

Depression can very depending on your level of depression up to 18g per day but I have been using 5g twice per day for the last 2 weeks and has worked wonders. Even at 2g twice per day when I first started I could tell a huge difference. My mom passed Sept 11 2016 and my grandmother Jan 3 2017. These are the 2 people that raised me and only close family I had. It sent me into a depression so great I didn't leave my house for since my grandmothers funeral. After starting this a little over a month ago. I am now active, out and about and almost back to my old self. Went fishing 4 times in the last week. Down side is I'm spending lots of $ on my new outings lol .

This stuff is the miracle supplement. It helps more than what I have listed here but these thing are what we use them for and have shown to actually work with us.

Also If anyone is looking for sperm count support this should be paired with L-Arginine and L-Carnitine Fumate. I also use One a Day vitamins which I will be switching out when I can buy everything to make my own.

Wife uses this with One a Day prenatal vitamins which will be switched out also when we can buy everything to make our own.

Hope this review helps. *

Not in 10,000 Words
I cannot describe how relieved I am to have finally found a reliable supplier of this substance. It is not just a matter of gaining bulk for vanity - this powder represents my key to a normal, happy life. Without it, I would be lost in the world, and eventually gone from it. Thank you, Bulk Supplements. ^^*

Great Stuff!
I use Inositol to help with PCOS (Poly Cystic Ovarian Syndrome) and one of the side effects which is hair thinning. Inositol helps stop shedding hair and allows my hair to grow back in. I really prefer the powder form because it is easier for me to take. *

vitamin b8
I have been using this vitamin supplement for awhile now and I notice a bit of an increase in energy and focus when I use it regularly. Good product.*

On 4/15/2018 William said...

Been a smooth week
I’ve managed to up my daily dose significantly, and have noticed minor benefits, but nothing major yet. I’m still under the recommended dose, but trying to ease up there so I avoid any potential discomfort. The powder itself is pleasantly sweet and easy to get down. I tried dissolving in hot beverages for the first couple days, but realized it goes down just as smooth with water. Order was shipped really fast!*

On 4/4/2018 Ainslee said...

Excellent form and consistency
I have been using this for a few days and the purity and consistency is better than my previous brand. It's great and much cheaper.*

On 3/28/2018 Ahmed said...

Great stuff!
The Inositol powder was recommended to me by a trusted physician! He also recommended bulksupplements for the best price and high quality. I am satisfied with this product and would purchase again.*

Long time user
I have been supplementing with inositol for a number of years and can tell when I am off of it. The water soluable semi sweet powder is an easy addition to my tea.*

On 3/27/2017 Barry said...

Best deal around
I scoured the internet and couldn't find a deal half as good as this for high doses of inositol. It just makes sense to buy it here if you take the 12-18g a day doses recommended for anxiety!*

Great price!
I take 4 tsp. a day. This is the best price I've found for inositol.*

On 10/26/2016 Barbara said...

Great value!
As other readers have commented, this is the most economical price for this product, esp. when you have to take high doses. *

On 10/26/2016 Barbara said...

Great Sleep Aid!!!!!
I'll take 1/4 to 1/2 teaspoon before bed and sleep beautifully! No handover feeling in the morning either! This pure powder inositol works! Great price at BulkSupp too!*

Love the Inositol
It helps me function better. I really like the fact that it has no flavor and water soluble.*

Inositol many health benefits
I have been practicing high protein–low carb diet and HIIT training longer than should have; and, apparently, messed up with my hormones composition. I did not want to take hormones to stabilize it. Recently I saw the video posted on BulkSupplements FB page about Inositol and its effect on skin, hair, hormonal imbalance, depression, and anxiety. That is why I decided to give it a try. I have been taking it for about a week, in the morning, before breakfast the recommended on the package doze. So far so good. After reading other reviews I think I will start increasing daily intake.
The pure powder mixes very well with water, has no noticeable taste or smell. It probably takes some more time to notice changes in mood, skin and hair, but so far I feel good. *

Inositol (clalming vitamin B8)
I was thrilled to find that you had inositol in powder form and in bulk. My daughter has dealt with a lot of anxiety. She takes 1 tsp with water in the morning, 1 tsp in a water bottle to sip on throughout the day, and 1-2 tsps before bed.She has found this to be very calming to her. She is able to get through each day with less fear and a more positive attitude. Thank you for your GREAT product and fast shipping.

Vitamin B Inositol
I currently take 4 grams of inositol a day, i am gradually building up to hit 15 grams a day. I have been told this is great for anxiety and skin picking. I have noticed a decrease in skin picking, it hasn't completely stopped but it has gotten better. I still find if I am bored my hand need something to do, but this has helped eliminate this a bit which is very exciting to me. i am sure when i finally get up to 15 grams it will have helped even better!!! *

On 1/20/2016 Liliana said...

I take 2 tsp. of inositol 2-3 times a days for anxiety an depression. [Research show 12 to 18 grams a day may be effective in ameliorating anxiety and depression.] It mixes well with water and the taste is mild and easily tolerated. I took it daily early this year (albeit less) and found myself more calm and even. I am going to try it again. I appreciate the ability to buy in bulk considering the dose needed. Pleased with the product so far. *

inositol & choline
I take this about an hour before bed, calms me and takes me into a restful nights sleep. Since I started ordering from BS I have completely abandon all other websites for my herbal supplements, nothing like getting what you pay for instead of a bunch of fillers love you BS you"re a GOD SEND.*

Sweet Taste
pure and sweet tasting. another great product.*

On 12/5/2015 Lois said...

inositol experience
This product has proven its purity. I take it at night to calm down before bed and have gotten results. I recommend taking 8-10grams before bed for best results.*

On 11/27/2015 David said...

Quality Product
The inositol from Bulk Supplements appear to be of high quality. Oderless, pure white, and a slightly sweet taste (it is a carbohydrate.) Seems to quiet my mind a bit, though the large doses required mean I only use it occasionally.*

On 9/7/2015 Brian said...

I take about 1/5th teaspoon at night to ensure I sleep promptly! if melatonin gives you issues try inositol from this company, take enough of it and youll be a lil drugged, the good kind of drugged lol don't worry studies have shown its safe even in large doses (although large doses might cause stomach issues). great thing is it has virtually no taste!*

Inositol and Mood
Inositol is amazing! Keeps my mood even and I am much more relaxed, calm and happy! Also easier to get along with...starting with myself! Love it!*

On 8/3/2015 Jeanne said...

I decided to start taking inositol and choline for neuropathy and anxiety. While it's too early to tell for certain, I do feel some improvement. I have ordered from before - for their consistently lower prices and for the speed with which I get my order. Being a careful consumer, I do a lot of research before I buy. I found here the lowest prices and top quality. My order always arrives within a few days. I have nothing but good things to say about this company. Five stars all the way.*

On 7/4/2015 Tim said...

This supplement is AMAZING!!! My mood has changed dramatically since I started taking it! Won't ever go without out it now!*

On 6/30/2015 Jeanne said...

I've been taking Inositol in a capsule form from another vender for a few months (along with Choline). The bulk form seemed perfect to add to my morning smoothie. I had a bit of a problem with payment processing on my first order (technological issues), but other than that, the product arrived quickly, and customer service was great. I've only just begun with the new product, but if the purity is what they state, I expect this will be a great value, and a good way to increase my dose without draining my wallet. There is no problem with taste, and it blends well into the smoothie. I'll defer long term comments to results that may take weeks to months to notice, but so far, it's been a pleasant experience. *

Subsutiting for SSRIs
Inositol has been helping after scaling back and stopping escitalopram, in combination with some other vitamins and herbs.

This product is of high quality and great value, like everything I've ordered from Bulk Supplements.*

Inositol B8 powder
Although I was skeptical when reading information and al the reviews online I ordered to see if it was effective. This supplement is very helpful with reducing symptoms of anxiety, improved sleep, increase in energy; overall more feeling of well balance.*

On 7/21/2014 Annette said...

Awesome Vitamin
I am extremely happy with this product. My mother, daughter and I use the B8 via injection. I mix it with other vitamins from this company and special sterile water for injection and it does wonders for us. I feel relaxed, focused and basically more at ease. The service from this company is also outstanidng. I'd been corresponding, asking questions to make sure that the product was indeed injectable and the help and information provided were very valuable in my decision. I then consulted with my doctor and he agreed. I will continue using the vitamins since they cost a fraction of the price I was paying. Thank you.*
