HelloPharmacist Scorecard of Memory Optimizer by Shaklee
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
Memory Optimizer contains three active ingredients. Vinpocetine is used to support blood flow and cognitive function.
Bacopa extract comes from an herb traditionally used in Ayurvedic medicine and is included for its potential cognitive-supporting properties. The product also contains Polygala Root Extract, though we have no data on that ingredient.
The capsules include maltodextrin and titanium dioxide as inactive ingredients.
Does it work?
Not established
The evidence for these ingredients is limited. Vinpocetine is rated possibly effective for dementia, but for other conditions it's aimed at—tinnitus, motion sickness, stroke, and chronic fatigue—the evidence is insufficient to establish whether it works.
Bacopa extract has insufficient evidence for all the uses studied so far, including Alzheimer disease, ADHD, cognitive function, and cognitive impairment. In short, what this product is intended to do isn't yet well proven.
How safe is it?
Well-documented data
Vinpocetine is generally well tolerated in the short term, but long-term safety data are limited. Common side effects include anxiety, dizziness, headache, flushing, stomach discomfort, and sleep disturbances.
Rare serious effects include abnormally low white blood cell counts and heart arrhythmias. Bacopa is also generally well tolerated, though gastrointestinal side effects (abdominal cramps, diarrhea, nausea, bloating) occur in 12% to 30% of trial participants.
Headache, drowsiness, and insomnia have also been reported. The safety data advises against both vinpocetine and bacopa in pregnancy.
There isn't enough information to know whether either is safe while breastfeeding—talk with your pharmacist or doctor for personalized guidance.
Meds to double-check
Moderate interaction found
Before taking Memory Optimizer, check with your pharmacist if you take blood thinners or antiplatelet drugs (including warfarin), anticholinergic or cholinergic medications, cevimeline (for Sjögren syndrome), thyroid hormone, or any drug processed by the liver—which covers a very long list. We documented Moderate interactions with all of these.
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.
This product is marketed for memory and cognitive support, but the evidence that it works is weak or absent. The bigger concern is that it interacts with a large number of medications across multiple types—especially blood thinners and drugs processed by the liver.
If you're on any prescription medication, check it with the tool on this page before you start. Talk to your pharmacist about whether this is right for you.

Memory Optimizer by Shaklee Drug Interactions
HelloPharmacist Interaction Report
Memory Optimizer by Shaklee contains two ingredients we have interaction data for, and both carry documented Moderate-severity interactions with several medication types.
Vinpocetine, the first active ingredient, may increase bleeding risk when combined with blood thinners (anticoagulants) and antiplatelet drugs—including warfarin—because it can thin the blood slightly and reduce how quickly red blood cells clump together. It also may theoretically increase levels of drugs broken down by the liver enzyme CYP2C9.
Read the full breakdown — every affected drug type, severity by severity
Backopa extract, the second active ingredient, has broader theoretical interactions: it may increase levels of multiple drug types processed by liver enzymes (CYP1A2, CYP2C19, CYP2C9, and CYP3A4 substrates), though whether this matters in real people isn't established. Bacopa may also counteract anticholinergic drugs (medications that block certain nerve signals) or add to the effects of cholinergic drugs (medications that enhance those same signals).
One reported case links bacopa to severe symptoms when combined with cevimeline, a Sjögren syndrome medication. Bacopa might also theoretically add to the effects of thyroid hormone.
We could not check Polygala Root Extract—we hold no data for it. Altogether, these interactions span 983 individual medications.

For each ingredient in Memory Optimizer 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.
Bacopa extract
Anticholinergic Drugs
Theoretically, concurrent use might decrease the effectiveness of both agents.
Bacopa seems to inhibit acetylcholinesterase and might increase acetylcholine levels, which could counteract the effects of anticholinergic drugs. Similarly, anticholinergic drugs might counteract the cholinergic effects of bacopa.
Cevimeline (Evoxac)
Theoretically, bacopa might increase the effects and adverse effects of cevimeline.
In one case, a 58-year-old female taking cevimeline long-term for Sjogren syndrome experienced hyperhidrosis, malaise, nausea, and tachycardia shortly after taking a single dose of bacopa. Symptoms resolved after two days. Cevimeline is metabolized by cytochrome P450 (CYP) 2D6 and CYP3A4, and researchers theorize that bacopa may have inhibited these isoenzymes. However, it is unclear if bacopa causes clinically significant inhibition of either CYP2D6 or CYP3A4.
Cholinergic Drugs
Theoretically, concurrent use of bacopa with other cholinergic drugs might have additive effects.
Bacopa seems to inhibit acetylcholinesterase and might increase acetylcholine levels. Theoretically, this could result in additive cholinergic effects when used with cholinergic drugs.
Cytochrome P450 1A2 (Cyp1A2) Substrates
Theoretically, bacopa might increase the levels and adverse effects of CYP1A2 substrates.
Research on the effects of bacopa extracts on CYP1A2 enzymes is conflicting. Some in vitro evidence shows that bacopa extract can moderately and non-competitively inhibit CYP1A2, while other in vitro evidence suggests that any effect is unlikely to be clinically significant.
Cytochrome P450 2C19 (Cyp2C19) Substrates
Theoretically, bacopa might increase the levels and adverse effects of CYP2C19 substrates.
In vitro evidence suggests that bacopa extract can moderately and non-competitively inhibit CYP2C19 enzymes. It is not known whether this is clinically significant.
Cytochrome P450 2C9 (Cyp2C9) Substrates
Theoretically, bacopa might increase the levels and adverse effects of CYP2C9 substrates.
Research on the effect of bacopa extracts on CYP2C9 enzymes is conflicting. Some in vitro evidence suggests that bacopa extract can moderately and non-competitively inhibit CYP2C9, while other in vitro evidence suggests that any effect is unlikely to be clinically significant.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, bacopa might increase the levels and adverse effects of CYP3A4 substrates.
Research on the effects of bacopa extracts on CYP3A4 enzymes is conflicting. Some in vitro evidence suggests that bacopa extract can moderately and competitively inhibit CYP3A4, while other in vitro evidence suggests that any effect is unlikely to be clinically significant.
Thyroid Hormone
Theoretically, bacopa might have additive effects when used with thyroid hormone.
Animal research suggests that bacopa increases thyroxine (T4) levels in mice by about 40%.
Vinpocetine
Anticoagulant/Antiplatelet Drugs
Vinpocetine might increase the risk of bleeding when taken with anticoagulant or antiplatelet drugs.
Clinical research shows that vinpocetine decreases red blood cell aggregation, as well as plasma and whole blood viscosity. This effect has been seen with intravenous vinpocetine 1 mg/kg and oral vinpocetine 30 mg daily. Vinpocetine also seems to have antiplatelet effects.
Cytochrome P450 2C9 (Cyp2C9) Substrates
Theoretically, vinpocetine might increase levels of drugs metabolized by CYP2C9.
In vitro research shows that vinpocetine weakly inhibits CYP2C9. However, this effect has not been reported in humans.
Warfarin (Coumadin)
Vinpocetine might modestly increase the risk of bleeding when taken with warfarin.
Clinical research shows that the combination of warfarin and vinpocetine leads to slight increases in prothrombin time and the area under the concentration curve for warfarin. However, these increases were small, and researchers suggest that this interaction is not likely to be clinically significant in most patients.
