What Linq does
Linq starts in your gut. Butyric acid is the main fuel of the cells that line your colon (PMID 17973645), and the prebiotics in the formula feed the bacteria that make more of it. Four results come out of that.
Gut lining and digestion
Linq strengthens your gut lining, the barrier that decides how much of what you eat is absorbed and what stays out. It is the most direct effect and the first one you notice.
Gut-brain connection and mood
Up to 90% of the body's serotonin is made in the gut, which is why the gut-brain axis is not a metaphor: Linq supports focus and mood by working on the gut side of it.
Metabolism and appetite
Butyrate increases the number of mitochondria, the part of each cell that makes its energy, and improves insulin sensitivity (PMID 19366864). Together with inulin it raised GLP-1, the hormone that tells you you're full (PMID 28962046).
The epigenetic lever
Butyrate is the natural HDAC inhibitor your body already makes: it slows the enzymes that close chromatin, so genes stay readable, and through that same effect it switches on Nrf2, your cells' antioxidant switch (PMID 27799462). That is why Linq is one of the three pathways of the Activz epigenetic supplements.
How to take Linq
- 1 capsule, twice a day, with meals: that is when your gut is working.
- For a faster start, take 2 capsules twice a day during the first week.
- Keep it going for three months: the effect on your gut bacteria adds up month over month.
What's in each capsule
The US Supplement Facts, as printed on the bottle:
| Amount per serving (1 capsule) | |
|---|---|
| Proprietary Blend | 390 mg |
| Butyric Acid Complex** | * |
| Deglycyrrhizinated Licorice Root (DGL) | * |
| Fructooligosaccharides (FOS, from inulin) | * |
| Mannan-oligosaccharides (MOS, from glucomannan) | * |
Other ingredients: CyLoc™ alpha dextrin fiber matrix, Butyric Acid Complex 300 mg*, hypromellose (derived from cellulose) capsule, methylcellulose, isomalto-oligosaccharides, calcium laurate, L-isoleucine, plant amylase. 60 capsules per bottle.
- Butyric acid complex: the short-chain fatty acid that feeds your colon cells, held in a CyLoc™ dextrin matrix with DexKey™ release so it reaches the colon instead of breaking down on the way.
- FOS and MOS: prebiotic fibers that feed your good bacteria, so they make more butyric acid on their own.
- DGL: licorice root with the glycyrrhizin removed, used to care for the lining of the digestive tract (PMID 493863).
If you're pregnant or nursing, talk to your doctor before starting Linq.
Butyrate supplements compared
Every butyrate supplement is trying to do the same thing: get butyrate to your colon, where your cells use it. What changes is the form it comes in and what else is in the capsule.
| Sodium butyrate | Tributyrin | Linq | |
|---|---|---|---|
| What it is | Butyrate as a salt, the form most studies use | Three butyrate molecules on glycerol, released by digestive enzymes | Butyric acid held in a CyLoc™ dextrin matrix with DexKey™ release |
| Where it's built to work | Upper gut, unless coated | Small intestine, where fats are digested | Colon, where your gut lining uses it |
| Prebiotics included | No | No | FOS and MOS |
| Digestive lining support | No | No | DGL licorice |
Tributyrin vs butyrate: tributyrin is a way to carry butyrate past the stomach; it still gives you butyrate alone. Linq gives you the butyric acid, the prebiotics that make your own bacteria produce more, and DGL, in one capsule, twice a day.
Linq questions
Can I take Linq every day?
Yes, that is how it is made to be taken: 1 capsule twice a day, every day. A 60-capsule bottle lasts a month.
How long until I notice Linq?
The first changes in digestion come in the first weeks of taking it every day; the effect on your gut bacteria builds over three months.
Is Linq a probiotic?
No. Linq is a postbiotic, butyric acid, the compound your good bacteria make, plus two prebiotics, FOS and MOS, that feed those bacteria. It gives you the result a probiotic is taken for, without depending on live cultures surviving the trip.
Does Linq have side effects?
Linq is butyric acid and fiber. Like any soluble fiber, in the first days you may notice more bowel movements while your gut adjusts.
Is there a subscription?
No. Every Activz order in the US is a one-time order, shipped free by USPS in 2 to 5 business days. Nothing renews on its own.
