Xymogen RelaxMax: What It Is, Who It Fits & How to Take It

Quick answer: RelaxMax is a Xymogen® drink mix that puts five calming nutrients in one scoop: 2 g of myo-inositol, 500 mg of taurine, 100 mg of GABA, 75 mg of magnesium and 50 mg of L-theanine. It is built for adults who want everyday support for a relaxed mood and a healthy stress response without swallowing a handful of capsules. The label directions are one scoop stirred into 6 fl oz of cool water, one to two times a day.

Gwen Halloran is 47 and takes down courtroom testimony at 225 words a minute, which is why her shoulders sit somewhere near her ears by five o'clock. She does not trust anything sold as calm in a jar. So when her pharmacist, Dev Rao, mentioned a cherry drink mix a few customers had asked him about, she made him read her the back of the tub first. Five ingredients, every amount printed, no proprietary blend. "You can look each one up," Dev said. That night she did, one line of the label at a time.

Here is what that label actually says, and what the research behind each line does and doesn't show.

What is Xymogen RelaxMax?

RelaxMax Cherry is a powdered drink mix from Xymogen that combines an inositol, two amino acids, the calming neurotransmitter GABA and a chelated magnesium in a single scoop. Xymogen describes it as neurotransmitter support that promotes stress resiliency, and positions it for a relaxed mood, balanced neurotransmitter activity and healthy inhibitory (calming) signaling.

Every amount is disclosed on the Supplement Facts panel. Many relaxation formulas hide their doses inside a proprietary blend; with RelaxMax you can check each ingredient against the research, which is exactly what Gwen did.

The cherry version is flavored with natural cherry flavor, malic acid, natural red beet powder, citric acid and stevia. Xymogen states it's made without wheat, gluten, yeast, soy protein, animal or dairy products, fish, shellfish, peanuts, tree nuts, egg, GMO-derived ingredients, artificial colors, artificial sweeteners or artificial preservatives. Xymogen also makes an unflavored powder and a capsule version.

What does each ingredient in RelaxMax do?

Each of the five works on a different part of the same system: how nerve cells send, slow down and balance their signals. Here they are in label order, with what the human research shows and where it runs thin.

Myo-inositol: 2 g, the largest ingredient by weight

Myo-inositol is the form of inositol your cells use to build the phosphatidylinositol signaling system, which helps relay messages from receptors on the cell surface to the inside of the cell. Xymogen's product sheet notes that a typical diet supplies roughly 225 to 1,500 mg a day, so one scoop's 2 g is more than most people get from food. The inositol trials Xymogen cites used up to 18 g a day, which puts the 2 g here at the modest end. For context on tolerance, a review of myo-inositol safety data found mild digestive effects such as nausea and gas only at the highest dose studied, 12 g a day.

Taurine: 500 mg

Taurine is a sulfur-containing amino acid found mostly inside your cells, including in the brain and heart. It helps cells manage their water and electrolyte balance (osmoregulation) and keeps cell membranes stable. Xymogen includes it for that stabilizing role and notes that taurine interacts with GABA signaling. Most of that mechanism work comes from laboratory and animal research, so treat taurine as a supporting ingredient rather than the reason to buy the formula.

GABA: 100 mg

GABA is the main "slow down" messenger in your brain, and it's the ingredient that draws the most questions. The honest answer is that the human evidence for oral GABA is early. A 2020 systematic review of 14 placebo-controlled trials concluded there is limited evidence that oral GABA supports a healthy stress response and very limited evidence for sleep. A separate 2015 review in Frontiers in Psychology points out that studies disagree on how much supplemental GABA crosses the blood-brain barrier, and suggests some effects may run through the nerves of the gut instead. At 100 mg, GABA in this formula is a contributor, not the main event.

L-theanine: 50 mg

L-theanine is the amino acid that gives green tea its savory taste, and the 50 mg here matches a dose that has been tested directly. In EEG studies by Nobre and colleagues, 50 mg of L-theanine increased alpha-wave activity, the brain rhythm of a relaxed but awake state, compared with placebo. The authors describe this as relaxing the mind without inducing drowsiness. Higher doses have been studied over longer periods: in a four-week randomized trial in 30 healthy adults averaging 48 years old, 200 mg a day improved self-rated stress-related symptoms and sleep quality scores. Two of the authors worked for Taiyo Kagaku, which supplied the L-theanine; Taiyo is also behind Suntheanine®, the form RelaxMax uses.

Magnesium: 75 mg as di-magnesium malate

Magnesium is involved in more than 300 enzyme reactions, including the ones that let nerves fire and muscles release. RelaxMax uses Albion® di-magnesium malate, a chelated form bound to malic acid. The 75 mg per scoop is a top-up, not a full magnesium supplement: it's 18% of the Daily Value, so if your practitioner wants you on a larger magnesium dose you'd still take that separately.

The research on magnesium and feeling calmer is suggestive but uneven. A 2017 systematic review of 18 studies found that about half reported a benefit for self-rated anxiousness, all in people who were already prone to it, and judged the overall quality of the evidence poor.

Taken together, the case for RelaxMax is the combination and the transparency: five nutrients that support calm signaling in different ways, at disclosed doses, one of which (L-theanine) sits right at a studied amount.

How do you take RelaxMax?

Stir one level scoop into 6 fl oz of cool water and drink it, one to two times a day, or as your healthcare practitioner directs. That's the full set of label directions; everything else in the table below is practical guidance or what the label leaves open.

• Add up your magnesium. Two scoops of RelaxMax Cherry supply 150 mg. The NIH upper limit for supplemental magnesium is 350 mg a day for adults, so count your multivitamin and any separate magnesium too.
• Space it from certain medications. The same NIH fact sheet advises taking magnesium at least 2 hours apart from oral bisphosphonates, and taking tetracycline or quinolone antibiotics at least 2 hours before or 4 to 6 hours after a magnesium-containing supplement.

Who is RelaxMax for, and who should skip it?

RelaxMax suits adults who want gentle, daily nutritional support for a calm mood and steady focus, and who like the idea of one drink instead of several capsules. That usually looks like:

• People whose workday leaves them wound up by evening and who want support for a healthy stress response
• Anyone who already uses L-theanine or magnesium on its own and wants a broader formula
• People who have trouble swallowing capsules or prefer a drink they can sip
• Adults following a practitioner's plan that calls for inositol, GABA and taurine together

Talk to your practitioner first, or choose something else, if you:

• Take any prescription medication. Xymogen's label asks everyone taking medication to discuss potential interactions with their practitioner before use. This matters most for sedatives, sleep medicines, medicines for mood, and blood pressure medicines, since several of these ingredients work on the same calming pathways.
• Are pregnant or nursing. The RelaxMax label doesn't address pregnancy. Some single-ingredient GABA products carry a do-not-use warning for pregnancy and nursing, so get your clinician's OK first.
• Have kidney problems. The NIH notes that the risk of too much magnesium rises when the kidneys can't clear it well.
• Take a bisphosphonate or a tetracycline or quinolone antibiotic. See the spacing rules above.
• Are buying it for a child. The label gives no directions for children; ask a pediatric practitioner.
• Need a full magnesium dose. At 75 mg per scoop, it won't replace a dedicated magnesium supplement.

How does RelaxMax compare to other calming supplements we carry?

RelaxMax is the combination option; the alternatives below each give you one of its ingredients at a higher dose, or the same formula in a different format. The amounts come from each product's Supplement Facts panel, and prices are what CHP lists as of November 2026.

The practical read: if you want the whole formula and don't mind stirring a drink, RelaxMax Cherry is the better value per serving (about $1.07 a scoop against about $1.33 for a 4-capsule serving). RelaxMax capsules trade that for convenience. They carry a few more carriers (hypromellose capsule, hydroxypropyl cellulose, ascorbyl palmitate and silica) and no flavoring or stevia.

If your practitioner wants one ingredient rather than five, the single-ingredient options are simpler to adjust. Integrative Therapeutics GABA gives you 750 mg of GABA per capsule, more than seven times the amount in a RelaxMax scoop; its label adds warnings to avoid alcohol and not to take it while pregnant or nursing. Thorne® Theanine gives you 200 mg of L-theanine, four times RelaxMax's 50 mg, as its only active ingredient. Neither includes inositol, taurine or magnesium.

Is RelaxMax safe, and what are the side effects?

For most adults who aren't on interacting medications, the label amounts are modest. Xymogen's label lists no specific side effects; it asks you to check with your practitioner before use and to discuss any medications.

• Digestive effects. Supplemental magnesium in high doses can cause diarrhea, nausea and cramping, according to the NIH. At 75 mg per scoop this is uncommon, but it's the first thing to check if your stomach complains. Inositol's mild digestive effects showed up only at 12 g a day, three times the two-scoop maximum here.
• Feeling too relaxed. L-theanine is known for calm alertness rather than sedation, but responses vary. Try your first serving at home before you need to drive or concentrate.
• Stacking. Many calming formulas share these ingredients. Before adding RelaxMax, read the labels of your other supplements and total the magnesium, GABA and L-theanine.

As with any supplement, talk to your healthcare provider before starting, especially if you take prescription medications or manage a chronic health condition.

Is RelaxMax worth it?

Yes, if you want broad, everyday support for a calm mood in one drink and you value seeing every dose on the label. Xymogen RelaxMax Cherry pairs a tested dose of L-theanine with myo-inositol, taurine, GABA and a chelated magnesium, at a cost per scoop that beats buying the capsule version.

It's the wrong pick if you only want one ingredient at a higher dose, if you need a full magnesium supplement, or if you take medications nobody has cleared it with. The research on several of these ingredients is promising rather than settled, and the formula is a support for good habits like sleep and breaks from the screen, not a substitute for them.

Gwen, for her part, kept her notes. Two ingredients had more research than she expected, one had less, and none promised the overnight fix she was braced for. She took the list to her practitioner before she took the first scoop.
