HelloPharmacist Scorecard of SereniSelect by Moss Nutrition
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Full disclosure
SereniSelect contains 3 active ingredients. L-theanine is an amino acid thought to support calm focus without the jitters often linked to caffeine.
GABA (gamma-aminobutyric acid) is a chemical messenger in your brain involved in relaxation and sleep signaling. Holy basil leaf extract, also called tulsi, is an herb traditionally used to manage everyday stress.
The capsules also contain inactive ingredients—cellulose, microcrystalline cellulose, silicon dioxide, and vegetable stearate—which are standard binders and flow agents.
Does it work?
Not established
The evidence for what SereniSelect's ingredients do is limited. L-theanine is possibly effective for supporting cognitive function, but the data for anxiety, OCD, age-related cognitive changes, Alzheimer disease, and cancer support is insufficient.
GABA's effectiveness for anxiety, ADHD, athletic performance, cerebral palsy, and chronic bronchitis is not established in the data we hold. Holy basil's effectiveness for generalized anxiety disorder, asthma, headache, respiratory infections, dental plaque, and diabetes is also insufficient.
In short, we don't have reliable evidence that this product works for the conditions you might be considering it for.
How safe is it?
Well-documented data
L-theanine and GABA are generally well tolerated for short-term use, but long-term safety isn't well studied for either. L-theanine may cause headaches, drowsiness, increased sleep, or more vivid dreams; a rare pediatric case of facial tics was reported but not clearly linked to the ingredient.
GABA's most common side effects are drowsiness, nausea, gastric upset, minor throat burning, and muscle weakness. Holy basil is generally well tolerated short-term, with loose stools and nausea reported by a small number of trial participants.
For pregnancy, the safety data for L-theanine and GABA are insufficient—there isn't enough information to know either way, so talk with your doctor or pharmacist for personalized advice. Holy basil is rated possibly unsafe in pregnancy based on animal data, so it's best to avoid it if you're pregnant.
For breastfeeding, all three ingredients lack sufficient safety information, so discuss this with your doctor or pharmacist before use.
Meds to double-check
Moderate interaction found
Before you start SereniSelect, check with your pharmacist or doctor about these medication types. Blood thinner and antiplatelet drugs (like warfarin or aspirin)—holy basil may increase bleeding risk.
Blood pressure medications—L-theanine and GABA might lower pressure further. Diabetes medications—holy basil may increase low blood sugar risk.
Sedatives, sleep aids, and opioids—all three ingredients could add to drowsiness. Also check if you take pentobarbital (Nembutal) or any serotonergic antidepressants.
The bottom line
Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.
SereniSelect might appeal to someone seeking a multi-ingredient relaxation blend, but solid evidence that it works for anxiety or stress is lacking. If you take blood pressure medications, diabetes medications, blood thinners, or sedatives, you'll need to check your specific drugs with your pharmacist before starting—these are the highest-risk combinations.
Talk with your doctor or pharmacist about whether this product fits your needs and whether it's safe alongside anything else you're taking.

SereniSelect by Moss Nutrition Drug Interactions
HelloPharmacist Interaction Report
SereniSelect by Moss Nutrition contains three active ingredients—L-theanine, GABA, and holy basil leaf extract—that together interact with medications across several categories.
The most serious concern is a Moderate-severity interaction: holy basil may increase bleeding risk when combined with blood thinners and antiplatelet drugs (such as warfarin or aspirin) through effects on clotting.
Read the full breakdown — every affected drug type, severity by severity
L-theanine and GABA both carry Moderate-severity interactions with blood pressure medications (antihypertensive drugs); either ingredient might lower blood pressure further, raising the risk of dizziness or fainting. Holy basil adds a separate Moderate concern with diabetes medications, potentially increasing the risk of low blood sugar (hypoglycemia).
Holy basil also theoretically strengthens the sedative effect of the barbiturate pentobarbital (Nembutal), though human evidence is limited.
All three ingredients have Minor-severity interactions with central nervous system depressants (CNS depressants)—medications like sedatives, sleep aids, and opioids—that could cause extra drowsiness or sedation. L-theanine and serotonergic drugs (such as certain antidepressants) have a Minor interaction documented, though clinical reports of problems are lacking.
Altogether, these interactions span 747 individual medications. Use the medication checker on this page to search your exact prescriptions before starting SereniSelect.

For each ingredient in SereniSelect with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.
L-Theanine
Antihypertensive Drugs
Theanine might lower blood pressure, potentiating the effects of antihypertensive drugs.
Animal research shows that theanine can lower blood pressure in spontaneously hypertensive animals. Theoretically, concomitant use of theanine and antihypertensive drugs might potentiate the antihypertensive activity.
Cns Depressants
Theoretically, theanine might have additive sedative effects when used in conjunction with CNS depressants. However, it is unclear if this concern is clinically relevant.
Theoretically, theanine may compete with glutamate and/or increase plasma gamma-aminobutyric acid (GABA) levels, which could cause CNS depression. In one clinical study, some subjects taking oral theanine reported drowsiness.
Serotonergic Drugs
Clinical studies regarding the effects of L-theanine on serotonin levels are conflicting. Some studies suggest it can increase serotonin levels in the brain while others report that it may decrease them. Nevertheless, there have been no reports of l-theanine being a causative agent in serotonergic-related side effects or serotonin syndrome.
GABA
Antihypertensive Drugs
Theoretically, taking GABA with antihypertensive drugs might increase the risk of hypotension.
Some clinical research shows that GABA can decrease blood pressure in patients with hypertension.
Cns Depressants
Theoretically, GABA might have additive sedative effects when used in conjunction with CNS depressants. However, it is unclear if this concern is clinically relevant.
Endogenous GABA has well-established relaxant effects and GABA(A) receptors have an established physiological role in sleep. However, the effects of GABA supplements are unclear, as it is unknown whether exogenous GABA crosses the blood-brain barrier. Although there have been limited reports of drowsiness or tiredness with GABA supplements, these effects have not been widely reported in clinical studies. Additionally, intravenous GABA 0.1-1 mg/kg has been shown to induce anxiety in a dose-dependent manner.
Holy Basil leaf extract
Anticoagulant/Antiplatelet Drugs
Theoretically, holy basil seed oil might increase the risk of bleeding when used with anticoagulant or antiplatelet drugs.
Animal research shows that holy basil seed oil can prolong bleeding time, possibly due to inhibition of platelet aggregation. However, it is not known if this occurs in humans.
Antidiabetes Drugs
Theoretically, holy basil might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Small clinical studies show that taking holy basil can decrease fasting blood glucose and other measures of glycemic control in patients with type 2 diabetes.
Pentobarbital (Nembutal)
Theoretically, holy basil seed oil might increase the sedative effects of pentobarbital.
Animal research shows that holy basil seed oil increases pentobarbitone-induced sleeping time. However, it is not known if this occurs in humans or if this applies to other barbiturates or sedatives.
