HelloPharmacist Scorecard of Nourish My Brain by Peak + Valley
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
This product has four active ingredients. Ashwagandha root extract and lion's mane fruiting body extract are the two with the most research behind them; maca root extract and tremella fruiting body extract round out the formula.
The product also contains hypromellose and rice hull concentrate as inactive ingredients.
Does it work?
Moderate evidence
The evidence is thin across the board. Ashwagandha shows possibly effective evidence for insomnia, anxiety, stress, and generalized anxiety disorder, but that's a preliminary bar — it means the data suggests promise, not that it's proven.
For lion's mane mushroom, the evidence we hold isn't established for cognitive function, anxiety, Alzheimer disease, or other uses listed — the research just isn't there yet. Maca and tremella have no established effectiveness data in our files either.
How safe is it?
Well-documented data
Ashwagandha is generally well tolerated in the short term in healthy adults, though long-term safety data are limited. The most common side effects — diarrhea, nausea, vomiting, and gastrointestinal upset — don't happen often at typical doses.
Rare but serious concerns include liver damage and cases of low blood sugar. Lion's mane is well tolerated as a food, but its long-term safety as a supplement hasn't been studied well.
Gastrointestinal discomfort, nausea, and skin rash have been reported. Maca is generally well tolerated, though fresh uncooked maca may cause stomach pain.
The safety data advises against ashwagandha and lion's mane during pregnancy and breastfeeding because there isn't enough information to know either way — talk with your doctor or pharmacist for personalized advice. Maca also lacks enough safety data in supplement amounts during pregnancy and breastfeeding.
Meds to double-check
Moderate interaction found
Check before starting if you take benzodiazepines or other sedatives (ashwagandha may boost drowsiness), blood pressure medication (risk of low blood pressure), diabetes drugs (risk of low blood sugar), blood thinners or antiplatelet drugs (lion's mane may increase bleeding risk), immunosuppressants (both ingredients may interfere), thyroid hormone (ashwagandha may amplify effects), or drugs broken down by the CYP1A2 liver enzyme (ashwagandha may lower their levels).
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
This product may help with stress and mild anxiety if ashwagandha's preliminary evidence holds for you, but the proof isn't solid yet and the ingredient list doesn't establish benefits for cognitive or brain health. If you take blood pressure or diabetes medication, blood thinners, immunosuppressants, benzodiazepines, or thyroid hormone, you need to check your exact medications with the tool on this page before you start.
Talk with your pharmacist — there's a lot to sort through here.

Nourish My Brain by Peak + Valley Drug Interactions
HelloPharmacist Interaction Report
Nourish My Brain by Peak + Valley contains ashwagandha and lion's mane extract, both of which interact with medications.
Ashwagandha is the more significant concern — it may increase the sedative effects of CNS depressants (sedatives, anxiolytics, benzodiazepines), which is a Moderate severity interaction. It could also raise the risk of low blood pressure (hypotension) if you're on blood pressure medication, increase your risk of low blood sugar (hypoglycemia) with diabetes drugs, or amplify thyroid hormone effects and side effects.
Read the full breakdown — every affected drug type, severity by severity
Lion's mane mushroom may increase bleeding risk with blood thinners (anticoagulants) and antiplatelet drugs, and may have additive effects with diabetes medications or interfere with drugs that suppress your immune system (immunosuppressants). Ashwagandha also carries a Moderate risk with immunosuppressants and a Minor risk with certain drugs that are broken down by a liver enzyme called CYP1A2.
We could not check maca root extract or tremella fruiting body extract for interactions — we hold no data for them. Altogether, these interactions span 1,409 individual medications.

For each ingredient in Nourish My Brain 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.
Ashwagandha Root Extract
Antidiabetes Drugs
Theoretically, taking ashwagandha with antidiabetes drugs might increase the risk of hypoglycemia.
There is preliminary clinical evidence suggesting that ashwagandha might lower blood glucose levels. Theoretically, ashwagandha might have additive effects when used with antidiabetes drugs and increase the risk of hypoglycemia.
Antihypertensive Drugs
Theoretically, taking ashwagandha with antihypertensive drugs might increase the risk of hypotension.
Animal research suggests that ashwagandha might lower systolic and diastolic blood pressure. Theoretically, ashwagandha might have additive effects when used with antihypertensive drugs and increase the risk of hypotension.
Benzodiazepines
Theoretically, taking ashwagandha might increase the sedative effects of benzodiazepines.
There is preliminary evidence that ashwagandha might have an additive effect with diazepam (Valium) and clonazepam (Klonopin). This may also occur with other benzodiazepines.
Cns Depressants
Theoretically, taking ashwagandha might increase the sedative effects of CNS depressants.
Ashwagandha seems to have sedative effects. Theoretically, this may potentiate the effects of barbiturates, other sedatives, and anxiolytics.
Hepatotoxic Drugs
Theoretically, taking ashwagandha with hepatotoxic drugs might increase the risk of liver damage.
Ashwagandha has been linked to cases of acute hepatitis, liver failure, hepatic encephalopathy, autoimmune hepatitis, the need for liver transplantation, and death due to liver failure.
Immunosuppressants
Theoretically, taking ashwagandha might decrease the effects of immunosuppressants.
Ashwagandha has demonstrated immunostimulant effects in humans. Animal research has shown that ashwagandha can attenuate the immunosuppression caused by cyclophosphamide.
Thyroid Hormone
Ashwagandha might increase the effects and adverse effects of thyroid hormone.
Concomitant use of ashwagandha with thyroid hormones may cause additive therapeutic and adverse effects. Preliminary clinical research and animal studies suggest that ashwagandha boosts thyroid hormone synthesis and secretion. In one clinical study, ashwagandha increased triiodothyronine (T3) and thyroxine (T4) levels by 41.5% and 19.6%, respectively, and reduced serum TSH levels by 17.4% from baseline in adults with subclinical hypothyroidism.
Cytochrome P450 1A2 (Cyp1A2) Substrates
Theoretically, ashwagandha might decrease the levels and clinical effects of CYP1A2 substrates.
In vitro research shows that ashwagandha extract induces CYP1A2 enzymes.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, ashwagandha might decrease the levels and clinical effects of CYP3A4 substrates.
In vitro research shows that ashwagandha extract induces CYP3A4 enzymes.
Serotonergic Drugs
Some animal studies have reported that ashwagandha can enhance serotonergic transmission by altering certain serotonin (5-HT) receptors. However, there is no evidence to suggest that ashwagandha increases the risk of serotonin-related effects, and there have been no published case reports of serotonin syndrome when combined with other serotonergic drugs. Nevertheless, due to the lack of extensive studies on the matter and the fact that ashwagandha appears to affect serotonergic pathways, it would be prudent to exercise caution when combining it with drugs that affect serotonin.

Lion's Mane Fruiting Body Extract
Anticoagulant/Antiplatelet Drugs
Theoretically, lion's mane mushroom may increase the risk of bleeding when used with anticoagulant/antiplatelet drugs.
In vitro research suggests that lion's mane mushroom extracts can inhibit platelet aggregation.
Antidiabetes Drugs
Theoretically, lion's mane mushroom may have additive effects when used with antidiabetes drugs.
Animal research suggests that an aqueous extract of lion's mane mushroom can reduce serum glucose and increase serum insulin.
Immunosuppressants
Theoretically, concurrent use of lion's mane mushroom might interfere with immunosuppressive therapy.
In animal and in vitro research, lion's mane mushroom polysaccharides stimulate the immune system.
