Clinical Side Effects: Although most human clinical studies show very few adverse side effects for short term use with doses under 30mg of Withanolides, it is still unknown if long term use has any side effects. Some clinical reports have reported mild to moderate side effects which are similar to reports from users.

User Side Effects: Our research shows approximately 5%* of users report mild to strong side effects especially on higher doses. Side effects may be more prominent with some brands of Ashwagandha and may last more then 24 hours but stop after use. Common Reported Side Effects from users include: nausea, stomach aches/cramps, vomiting, diarrhea, lightheaded, dizziness, increased blood pressure, low blood pressure, heart palpitations, insomnia, lack of focus, nightmares, increased anxiety, headache, migraines, skin rash, allergic reaction, irritability and anger.

How to Read the Comparison Charts


This is the order we rated this product. This is our opinion and is based on the statistic comparisons research we have done. If there is no number ( – ) it means we believe it is equal to or not significantly different from product one above it.

Cost Per 500gm

Since different brands have different serving sizes and different amounts of the primary ingredient the fair way to compare them is to raise or lower each one to a set amount and determine how much that amount would cost. 

Active Ingredient Per 500mg

How much total active ingredient per every 500mg capsule/tablet/powder. 


A product that is GMP certified is made under the strictest guidelines set forth by the FDA. We believe this is very important and we may not even rate a Non-GMP product if they’re not 3rd Party Certified due to potential inaccuracy of the label. There’s no point comparing a false label to a real label.

3rd Party Tested

A product that is 3rd party tested by an independent company for purity and potency. We wont even compare a product that is not 3rd party tested because the label may be inaccurate unless it is GMP Certified. Products that are not GMP & 3rd Party Tested will not be compared. Read More . . . .

Good Added Ingredients

Some ingredients work well with other ingredients and can even boost the effectiveness of the primary ingredient or boost the over-all results but only providing there’s enough active ingredients to work.

Useless Added Ingredients

Some companies add unproven ingredients that don’t work or they add good ingredients but that are in such small amounts they are likely useless and are likely only there to attract uneducated buyers.

Proprietary Blend

Companies that use proprietary blends do so to protect their formula but a proprietary blend can also mean they can be using very little active ingredient since ther’re not required to list the amounts of each ingredient in a proprietary blend.
