Ü Relax 2.0 Review: Worth a Closer Look?

Ü Relax 2.0 is a powdered relaxation drink from Calming Co. marketed for people who want to unwind, take the edge off everyday stress, and support a calmer routine. The brand positions it around Dual-Action Cortisol Support™, with Bluenesse® Lemon Balm for faster support and KSM-66® Ashwagandha for longer-term stress resilience.

But are these ingredients strong enough to support the brand’s calming claims? Does the cortisol language need more context? And how does Ü Relax compare with capsule, gummy, and greens-based alternatives?

To answer these questions, we will examine the main ingredients, review the available research, look at the marketing claims, and compare Ü Relax with popular wellness products.

Ingredient Analysis

Ü Relax 2.0 has a focused formula. To keep this review useful, we looked at the five ingredients shown on the Lemon Lime Supplement Facts panel.

KSM-66® Ashwagandha Extract

KSM-66® Ashwagandha Extract is included at 300 mg per packet.

Ashwagandha is commonly used in stress-support supplements. In a 2012 randomized, double-blind, placebo-controlled study, adults with chronic stress took 300 mg of ashwagandha root extract twice daily for 60 days and saw greater stress-score and cortisol reductions than placebo^[1].

That study is relevant, but the dose matters. One Ü Relax packet gives 300 mg, while the study used 600 mg daily. The brand’s FAQ says optimal support is based on 2 packets daily, which lines up better with that research.

There is also a safety side to consider. A case series reported suspected liver injury linked to ashwagandha use, so people with liver concerns, thyroid conditions, pregnancy, medication use, or heavy supplement routines should be cautious^[2].

L-Theanine

L-Theanine is included at 200 mg per packet.

This dose is easy to evaluate because a randomized controlled trial used 200 mg of L-theanine daily for four weeks and reported improvements in stress-related symptoms and some cognitive measures in healthy adults^[3].

That makes L-theanine one of the more reasonable inclusions in the formula. Still, the study was small and not designed to prove benefits for anxiety disorders, insomnia, or clinical stress conditions.
So, L-theanine fits the calm-focus positioning, but users should expect subtle support rather than a dramatic sedative effect.

Bluenesse® Lemon Balm Extract

Bluenesse® Lemon Balm Extract is listed at 150 mg per packet.

Lemon balm has been studied for mood and stress-response support. In a study published in Nutrients, lemon balm-containing foods using a standardized extract commercially available as Bluenesse® were evaluated for stress and cognitive effects^[4]. The study tested 300 mg and 600 mg preparations.

This is relevant to Ü Relax, but again, the dose needs context. One packet gives 150 mg, while two packets provide 300 mg. That makes the brand’s “60-minute cortisol response” claim easier to understand only when the two-serving detail is included.

Magnesium Glycinate

Magnesium Glycinate is included at 100 mg, or 24% Daily Value.

Magnesium supports normal nerve and muscle function, and glycinate is often used in calming formulas. However, the stress evidence is not as strong as the marketing may suggest.

A 2017 systematic review on magnesium for anxiety and stress described the evidence as suggestive but inconclusive, largely because studies varied in quality and design.^[5]

So, magnesium is a sensible support ingredient, but it should not be framed as a guaranteed stress-relief nutrient.

Vitamin D3

Vitamin D3 is included at 25 mcg, or 1,000 IU.

Vitamin D is commonly linked with mood and general wellness, but results depend heavily on baseline Vitamin D levels. A 2024 study found mixed context across studies, meaning Vitamin D may be more relevant for people with low levels than for everyone.^[6]

In Ü Relax, Vitamin D3 adds daily wellness support, but it is not the strongest ingredient for immediate relaxation.

Our Ingredient Assessment

Ü Relax has a thoughtful formula with transparent dosing and several ingredients that can be compared with published research.

The strongest ingredients are ashwagandha, L-theanine, and lemon balm. The main limitation is that some of the better study comparisons appear closer to two packets daily, not one.

Overall, Ü Relax is best viewed as a daily calm-support drink, not a guaranteed cortisol solution or treatment for anxiety, insomnia, or stress-related medical conditions.

Scientific Evidence

Ü Relax 2.0’s main scientific basis is the combination of ashwagandha, L-theanine, lemon balm, magnesium, and Vitamin D3 for stress-response and relaxation support.

Ashwagandha has human research for stress and cortisol outcomes, but one of the more relevant studies used 300 mg twice daily for 60 days, which aligns more closely with two packets of Ü Relax than one.

L-theanine has been studied at 200 mg daily, which matches one packet of Ü Relax, but the available research was conducted in healthy adults and should not be stretched into disease-related claims.

Lemon balm research is also relevant, especially because the study involved Bluenesse®, but the tested amounts were 300 mg and 600 mg, while one packet of Ü Relax contains 150 mg.

Magnesium and Vitamin D3 may support general wellness, but the evidence for stress, anxiety, and mood outcomes is more mixed and depends on the person’s baseline status.

Overall, Ü Relax uses researched ingredients, but we found no published clinical trials evaluating Ü Relax 2.0 as a finished product.

Marketing Claims

Ü Relax 2.0 uses polished wellness language around cortisol, calmness, stress resilience, and winding down.

Dual-Action Cortisol Support™

The brand describes Ü Relax as being powered by Dual-Action Cortisol Support™, with lemon balm for faster support and ashwagandha for longer-term resilience.

This has a reasonable ingredient basis, but cortisol is affected by sleep, timing, stress level, food intake, exercise, illness, and testing method. A daily drink should not be assumed to “fix” cortisol for every user.

Rapid Cortisol Support

The FAQ says the 60-minute cortisol-response claim is based on 2 servings of Ü Relax.

This detail matters because the label serving is one packet. Consumers may miss that distinction if they only read the front-page claim.

Calm, Clear, and Steady

The brand says Ü Relax supports a calm, clear, steady feeling without drowsiness or fog.

This fits the formula, especially with L-theanine. Still, calming ingredients feel different for different people. Some may feel relaxed, some may feel sleepy, and others may notice only a mild effect.

Our Verdict on the Marketing Claims

Ü Relax has a clear concept and a better ingredient story than many generic relaxation drinks.

However, some claims need dosing context, especially the cortisol language tied to two servings. We recommend viewing it as a daily stress-support drink, not a treatment for anxiety, insomnia, alcohol cravings, cortisol disorders, or any medical condition.

Overall Comparison

Ü Relax is the most drink-focused and cortisol-positioned option. WOWMD® Ashwagandha is the simplest ashwagandha capsule. WOWMD® Reishi Relax Gummies offer a more traditional relaxation blend in gummy form. Superfood Greens Fusion is better suited for broader daily wellness.

Ü Relax 2.0 Pros and Cons

• Contains clearly listed doses for the main ingredients.
• Has 0 calories and 0 g sugar per packet.
• Powder format may suit users who like drink-based routines.
• Offers a 90-day happiness guarantee.

• We found no published clinical trials on Ü Relax 2.0 as a finished product.
• Some study comparisons appear closer to two packets daily, not one.
• Ashwagandha may not be suitable for everyone.
• The cortisol language may sound stronger than the finished-product evidence.
• Some users may prefer capsules or gummies.

Final Verdict

Ü Relax 2.0 is a well-structured relaxation drink with transparent doses of KSM-66 ashwagandha, L-theanine, Bluenesse lemon balm, magnesium glycinate, and Vitamin D3.

The formula has a reasonable research basis, especially for ashwagandha, L-theanine, and lemon balm. However, we found no published clinical trials on Ü Relax 2.0 itself, and some study comparisons appear closer to two packets daily than one.

Overall, Ü Relax may be worth considering for users who want a sugar-free calming drink, but it should be approached with realistic expectations and healthcare guidance when needed.
