Which Brand Of Ashwagandha Supplement Should You Buy?
Ashwagandha has been called the king of Ayurvedic herbs. It’s best known for reducing stress and anxiety. It may also modestly enhance various aspects of physical performance, increase testosterone levels, and improve reproductive health, but more research is needed to confirm these effects.
The herb extract works by altering the signalling of several neurotransmitters that are not working correctly leading to anxiety disorders. It's also able to reduce cortisol levels in the brain which leads to regulation of health problems such as anxiety and depression.
The mental health crisis worldwide now has reached epidemic proportions with 1 in 6 people now being affected by stress, anxiety and depression. Luckily there are herbs like Ashwagandha that can help and the supplement industry capitalised on its benefits and offers the supplement mostly in capsule form.
The question is which brands are all hype and marketing and which brands actually produce good quality supplements?
The answer can only be answered by hitting home some truths about the way Ashwagandha is absorbed and exposing some of the tricks brands use to trick customers into thinking they are the leading brand.
Here at Supplement Informer, we understand how tough and overwhelming it can be to study, research, and pick the best Ashwagandha brand supplement.
That's why we've done all the hard work for you?
We searched for the top-selling Ashwagandha supplement brands on the market and purchased all of them so we could personally test them and consult with our team of nutritionists who provided some much needed insight on the quality of all the different Ashwagandha supplements on the market.
Who Should Take Ashwagandha Supplements?
Treating
- Sufferers of stress and anxiety
- Sufferers of depression
- Men with low testosterone or fertility issues
- Sufferers of Diabetes
- Suffers of Insomnia
Improving
- Improved physical performance
- Improved memory and cognitive function
Studies on Ashwagandha have used dosages of 250–600 mg/day of a root extract. The most common dosing protocol is 600 mg/day divided into two doses, with one taken in the morning with breakfast and the other in the evening. Anything higher is usually not absorbed or too strong and can cause drowsiness.
Any brand that provides a delayed release formula over a formula which enters the system in one go is preferable because delaying the release of the herb over a period of time reduces the side effects of drowsiness. Additionally a delayed release capsule ensures you receive the power of the supplement with little to no wastage.
What to Look for in an Ashwagandha Supplement?
Must Haves
- Dose of 600mg or less is prefereable
- A Delayed release capsule required for an even release
- Look for Ashwagandha KSM-66® on the packaging
- Natural Ingredients
Must Avoid
- Dosing at more than 600mg per day can cause drowsiness
- Amazon products with fake reviews
- Cheap Brands with fillers and no added beneficial ingredients

The Bottom Line

What We Loved
Rock & Roses is the only brand on the market that uses the recommended dose of KSM-66 Ashwagandha in conjunction with Delayed Release Capsule Technology. It's 2 a day capsule dose is the optimal way to supplement working alongside the delayed release capsule to ensure even delivery of the supplement throughout the day.

Rock & Roses is the only company offering a No-questions-asked 90-day money-back guarantee.
Plus, they’ve thoughtfully engineered the vitamins to provide the most optimal results. Here are a couple of ingredients they include which other brands don't..
- 100mg Lemon Balm Extract - Promotes additional benefits to reduce stress and anxiety along with boosted brain and cognitive function
- 50mg Korean Ginseng Extract - Strengthens the immune system and helps fight off stress and disease.
- 50mg Siberian Ginseng Extract - An adaptogen which helps the body better cope with either mental or physical stress.
- 25mg L-Tyrosine - A Powerful amino acid that can help increase happiness, improve memory, and manage stress.
There’s just one small thing…
Rock & Roses is a small-sized company right now. Compared to other household name brands, they don’t have a massive inventory of Ashwagandha KSM-66 Delayed Release.
In other words, with higher demand than the supply, their inventory sells out fast.
The good news is:
If you’re reading this page, you can still take advantage and stock up on bottles of Ashwagandha KSM-66 Delayed Release
So, before Ashwagandha KSM-66 Delayed Release sells out fast… which is possible within 24 hours, Rock & Roses highly recommends that you buy and stock up now.
Manufacturing may take 3-6 months depending on the availability of ingredients. And with the delay of shipment due to the current worldwide situation, it may take customers 10 or more weeks before they can get bottles of the Ashwagandha KSM-66 Delayed Release.
