Why Detoxy Contains Vitamin C: A Guide to Asc2P
Asc2P is one of the most interesting ingredients inside Detoxy, and it deserves a spotlight of its own. This stabilized form of vitamin C has an unusual name and a simple job, and I’m excited to walk you through it in plain language.
You’ll find Asc2P on the label of both Detoxy and our Feel Good Vitamin C Serum. Let’s get into what it is, what the research says and why we chose it.
Key Takeaways
-
Asc2P is vitamin C attached to a phosphate group and paired with magnesium, which protects it from the rapid breakdown regular vitamin C is known for.
-
In a study on human skin cells, the magnesium form of ascorbyl-2-phosphate stimulated collagen production as effectively as ascorbic acid and stayed stable in solution for nine days.
-
Enzymes convert Asc2P into regular vitamin C, so your body can put it to use.
-
NIH notes that vitamin C acts as an antioxidant that helps protect cells from free radical damage and is needed to make collagen.
-
Most Asc2P research is lab-based, topical or animal-based. Large human trials on oral Asc2P are still limited.
What Is Asc2P?
Asc2P stands for ascorbyl-2-phosphate. In Detoxy, it’s magnesium L-ascorbyl-2-phosphate, which is vitamin C joined to a phosphate group and paired with magnesium.
The phosphate acts like a protective cap, shielding the vitamin from the breakdown that makes regular vitamin C so delicate. When your body needs it, enzymes remove the phosphate and release usable vitamin C.
A 2025 review of vitamin C derivatives describes magnesium ascorbyl phosphate as a stable form that is converted into ascorbic acid by phosphatase enzymes.
Why Stability Matters
Regular vitamin C, also called ascorbic acid, is famously fragile. It oxidizes easily, which means it can lose its power before it ever does its job.
A study on human skin cell cultures put this to the test. Ascorbic acid was unstable at neutral pH, while the ascorbyl-2-phosphate salts held steady even after nine days in solution. The magnesium salt was also equal to ascorbic acid in stimulating collagen production in those cells, which is why it’s the form we chose.
Why Vitamin C Belongs in a Cleansing Formula
Vitamin C is one of the best-known antioxidants. The NIH describes it as a nutrient that helps protect cells from damage caused by free radicals, and your body also relies on it to make collagen.
In Detoxy, Asc2P teams up with oxygenated magnesium. Here’s what it’s designed to do:
-
Support sustained antioxidant protection by delivering vitamin C that your cells can use
-
Help neutralize free radicals your body generates as it goes through its natural cleansing processes
-
Stay stable and long-lasting, without the rapid breakdown of regular vitamin C
Meanwhile, the oxygenated magnesium supports gentle elimination and regularity. Together, they give you a formula designed to help your body let go of what it doesn’t need while keeping your cells supported along the way. You can read more about that half of the formula in our guide to oxygenated magnesium.

Meet Detoxy: Gentle Daily Cleansing
Everything above comes together in Detoxy, our gentle approach to daily cleansing. It pairs oxygenated magnesium for easy, regular elimination with Asc2P for steady antioxidant support, and it’s made without the harsh or irritating herbs that often bring discomfort or dependency.
When digestion feels off, it colors your whole day. Detoxy was created for the frustrations that come up again and again:
-
Going days without a bowel movement. The waiting game is uncomfortable, and it’s hard not to wonder what’s normal for your body.
-
Bloating and gas. That tight, puffy, heavy feeling can follow you around long after a meal.
-
Feeling sluggish. When elimination slows down, energy and that fresh, light feeling often go with it.
-
Cleanses that feel too harsh. Many herbal cleanses bring cramping, urgency or the sense that your body is starting to depend on them.
How it works: The oxygenated magnesium is designed to release oxygen as the capsules dissolve, supporting gentle elimination. The magnesium also draws water into the intestines, which helps keep stool soft and easy to pass (we cover the research in our guide to oxygenated magnesium). Asc2P adds stabilized vitamin C for sustained antioxidant support along the way.
Each bottle holds 90 vegetarian capsules. The formula is vegan, gluten free, dairy free and free of preservatives, and it needs no refrigeration.
That gentleness is what customers mention most. Mirela G. shared, “It works gently but effectively, helping me be regular without cramping or discomfort.” And Scott B., who has taken Detoxy for years, wrote, “I’ve been taking Detoxy for at least six years and am so grateful for how light it makes me feel.” Detoxy is rated 4.9 out of 5 stars across 751 reviews, with 97% of reviewers saying they’d recommend it.
Detoxy pairs beautifully with a resilient probiotic and digestive support. SBO Probiotics+ and Digestive Enzymes round out the routine.
Asc2P Beyond Detoxy: Our Feel Good Vitamin C Serum
Asc2P is also the star of our Feel Good Asc2P Vitamin C Serum, and this is where the stability we’ve been talking about really shines. Regular vitamin C is delicate in a skincare bottle and can lose its power long before you reach the bottom of the serum. Asc2P is a steadier choice, and enzymes in the skin convert it into usable vitamin C once it’s applied.
What Customers Are Saying
The serum is rated 4.8 out of 5 stars across 149 reviews. Sheree M. shared:
“This Vitamin C serum is absolutely wonderful! I have a very simple skincare routine and this serum has become essential... This serum really brightens my face. This is my 3rd bottle and I don’t plan on ever doing without it!”
And Michelle S., who has sun-damaged skin and sensitivity, wrote:
“I’ve been using the Vitamin C Serum for several weeks consistently and absolutely notice my skin tone evening out and the redness calmed, making my sun damaged skin appear brighter. Immediately upon applying my skin feels firmer.”
It’s a lovely full-circle idea: Detoxy supports your body from the inside, and the serum supports your skin from the outside. If you’re curious how the two connect, our guide to the gut-skin connection explains why your skin so often reflects what’s happening in your digestion.

FAQ
What is Asc2P?
Asc2P is magnesium L-ascorbyl-2-phosphate, a stabilized form of vitamin C. Enzymes in the body convert it into regular vitamin C.
Is Asc2P the same as regular vitamin C?
It becomes vitamin C once enzymes remove the phosphate. The big difference is stability, since Asc2P resists the breakdown that ascorbic acid is prone to.
Why is Asc2P in Detoxy?
It adds antioxidant support to a formula designed for gentle cleansing, giving your cells vitamin C while the oxygenated magnesium supports regularity.
Does Detoxy replace my vitamin C?
No. Detoxy contains vitamin C as a supporting ingredient, so keep enjoying vitamin C-rich foods like citrus, bell peppers and strawberries.
Small Ingredient, Big Support
Asc2P might have a tongue-twister of a name, and its purpose is wonderfully simple: keeping vitamin C stable so it can do its work. Inside Detoxy and on your skin, it’s one of the details that makes our formulas feel so thoughtful.
