Detox C – Premium Corn-Free Vitamin C
Adrenal fatigue, reduced immune function, and increased inflammation are just a few of the side effects caused by a lack of vitamin C. And according to research, this crucial nutrient may play a major role in the repair and recovery process of those with gluten sensitivity.
The scientific literature has confirmed vitamin C’s key role in:
- Immune system function
- Collagen repair and formation
- Joint function
- Energy production
- Antioxidant protection and function
- Detoxification, and more
The vast majority of vitamin C supplements are derived from toxic GMO corn. That’s why I formulated Detox C. This unique formula is pH-balanced and grain free.
Some of its unique features include:
- Fully reduced to preserve its integrity – Produced under a nitrogen blanket ensuring that you get a vitamin C supplement that is not oxidized.
- Buffered with minerals to prevent acidity or upset stomach.
- Designed in both tablet and powder form to suit your preference.
Key ingredients include:
- Vitamin C (as 100% l-ascorbates, fully reduced and buffered)
- Calcium
Does Not Contain: Gluten, MSG, soy, yeast, dairy, GMOs, fillers, preservatives, synthetics, or other hidden ingredients. It is 100% plant sourced and safe for vegetarians.

Been purchasing over the counter vitamin c but decided to try this one. Felt a huge difference when we take it verses a regular otc brand. I feel like it has made me feel allot better taking this vitamin c compared to others I have taken in the past. I have cytomegalovirus and can feel very lethargic so this has helped a ton. I take about 4 pills a day for this reason. I wanted the powder but they were out of that and got this one instead. Very happy with this choice and the price point is right on.

I’ve been using this product for 2 weeks so far… After I’ve reviewed this product from many people on Dr Osborne community website and asking more questions and get many answers I felt this product is absolutely good for me. My body became more resistant to viruses. It helped me to fight viral infection and helped me to flush out all the toxic out of my body.

I have now purchased second set of this product and it’s excellent. I have stomach ulcer history and it is not as harsh as other expensive vit c products out there. I recommend this product to anyone who might want to take C but afraid of the gastric effects. In addition it is Dairy free and I’m highly sensitive to casein so this is excellent.

It is very difficult to find a Vitamin C with no citric acid or corn. After reading his No Grain No Pain I discovered I had to do more than remove wheat, barley, rye. I looked at my supplements & realized I’ve been taking corn or rice products for years. I feel much better since removing corn/citric acid/ xanthum gum/ rice. I wanted the powder but it was out of stock. I will definitely buy the powder on my next order. I am buying Vit C for my parents to take as well especially with this coronavirus ordeal!
Lani S. –
This is the only C I have found that is not made from corn which I cannot have; so I am very appreciative for this product. Dr Osborne is my favorite trusted doctor.
Gail L. –
At this point my husband and I are both taking this product. I chose this brand because I know Dr Osborne helped to create it. I trust that he uses the best source of ingredients to strengthen my body and protect me from immune issues. I can truly say that don’t readily see or feel a difference in the few weeks that I have been taking this Vitamin C, it is just peace of mind knowing it is benefiting my body.

I take so many supplements that I don’t know what helps and what doesn’t, truthfully. I DO know that I have been taking Vitamin C for several years and find this formulation very much to my liking because I feel it’s a better C to take than others I have taken before, especially with the added ingredients. I’m taking 5000-8000 mg. a day in this time of possible disease everywhere, and I am VERY comforted knowing that my immune system is being helped by Detox-C.
James B. –
These tabsules are giving me the efficient amount of Vitamin C that I need every day.

I actually wanted the powdered vitamin c detox & ordered this by mistake. Because of covid19, I dared not return this product, so kept it & ordered a second batch of the powdered.. by then, Vitamin C was in short supply & I could only order one at a time.
I’m grateful to have this. My spouse & I each take several C tapsules through the day. We feel strong & well. Best Wishes for sustaining your good health.

Due to years of having an autoimmune disorder, I was not absorbing nutrition from my food. My gums were not doing well as per my periodontist. Takin this vitamin C has healed my gums and I am absorbing it much better because I gave up all grains. Also, the versions easy on the stomach, doesn’t cause cramps.

Detox C Tabsules & NAC- I have been taking this two products from Dr. Osborne shop for a while now, they are part of my routine especially during this time of the year that colds & flus love to shine their lights. I work in a place that I’m exposed to people that they come with all kind of conditions, so I take Vit C and NAC to re-enforce my immune system and it has work for more than 2 years now. Very pleased with both supplements, I will highly recommend both products.

I am so thankful for this. I have been GrainFree for 6 years, but so much Vitamin C is made from corn (I believe) that it was hard to find one I really wanted to put in my body. My body says “ Thank you Dr. Osborne”. This one is so good. God Bless you all.

Since doing the Vitamin C flush protocol and taking the Vitamin C I have noticed that my skin tags are slowly diminishing and some are gone completely.

This amazing Vitamin C product is on autoship for my family! It is an amazing supplement, and very obvious that much thought and attention went into its development – all the way to the shape of the tabsule, which is so easy to swallow. Great Product!

These are excellent. I have been grain-free since I read your book 6 years ago. Vitamin C is very important to me, but it has to be a good one because I take quite a lot of it. Thank you so very much for caring. God Bless you all.

I’ve been using Detox C for a couple of years after discovering that most C are derived from corn.
I would buy more, but I live in Canada and shipping cost + custom can be a problem…..

With small fiber neuropathy related to celiac disease, I wanted to try Dr. Osborne’s suggested combo for pain: Vitamin C + Quercetin. It was important to me to avoid sources of Vitamin C that contained corn and would do more harm than good. So I turned to Detox C. Shipped all the way to Canada super fast and I am now on my way to feeling better.

I have thrown out all of the suplements that I used take and replaced with Dr. Osbornes. It has been couple of months since I have been taking “C” and plus various Dr. Osbornes suplements and I am much more energized. I am so happy that I’ve found the suplements that I can totally trust!

I love this product. I heard Dr Osborne on a podcast about six years ago, purchased his book and have been gluten free every since. I’m 67 years old and have not missed a day of work in six years due to an illness, even through COVID! Thank you Dr Osborne.

Vitamin C – Been using GFS Vitamin C tabsules for quite some time now. The blend he has created is great and since we the people do not create our own vitamin C it is very important part of the immune system and our periodic table of elements. Really like this product
Elaine P. –
I’ve been using Detox Vitamin C for several months. The benefits I’ve experienced are…
1. Keep my immune system strong
2. Increase dosage when having cold like symptoms. As a result symptoms decreases in a matter of a day.
3. Great for detoxing along with a 3 day water fast, per Dr. Osborne. After 3 days I feel great with improved energy.
I highly recommend this product for overall health benefits.

What I like especially about this product is that it’s grain free.
So even though getting it to Canada is not convenient, I cannot do without it.
June H. –
Dr. Osborne’s Detox C has been my vitamin C supplement for many years. The tabsules are coated and easily swallowed. This grain free supplement is one of many I purchase from the Gluten Free Society and keeps my imune system strong.
Katrina A. –
Never want to be without this supplement. Everyone in my home takes it, and all benefit from and are grateful for it!

I use Detoc C 3 times a day, and the C powder twice, it has helped my autoimmune issues tremendously!! And helped my skin…thank you so much!
I used your surgery protocols, too, in March, which included C, and things went well. Thank you so much for your great products! Not having to pour over the ingredient list for gluten is such a relief, thank you…
Katrina A. –
My whole family takes this amazing supplement! It’s going on autoship!!
Suzanne L. –
My husband and I rely on Detox C every day, and the one time we ran out, we both came down with colds for the first time in years! I’m grateful it doesn’t contain zinc, since I’m very sensitive to it and have a bad reaction. Thank you, Dr. Osborne!

I take one tabsule of Dr. Osbornes gluten free vitamin C every morning with breakfast. I feel very safe and confident using his gluten free products. No digestion problems with taking this Detox C Tabsules – Gluten Free Vitamin C.

Start taking Detox C Tabsules first thing in the morning before my 30 workout with the Ad-Doer I own, then head out for a 9 or so mile walk. Upon returning home a couple of hours later I take another Detox C and usually take between 5 and 9 per day. It’s great and I try to follow what Dr. Linus Pauling stated about Vitamin C. Thanks to all at Gluten Free Society for giving us a gluten free Vitamin C
