"I started using this several years ago to help with middle-aged forgetfulness and foggy mindedness - it has worked very well for me. I ran out of this a few months ago and realized after a week or so how much this was really helping me, so I quickly reordered more!" ~product review by LittleGrayBird

  • Powerful hormonal precursor

  • Supports healthy brain function

  • 50 mg per capsule

Super-Strength Pregnenolone is our most powerful pregnenolone supplement to date. As a prohormone, pregnenolone contributes to an array of activities within the healthy human body. As a supplement, its primary use is in the support of healthy brain function. Pregnenolone is a neuroactive substance found highly concentrated within particular areas of healthy young brains. For this reason, supplemental Pregnenolone has been investigated for its potential to promote sleep quality and memory retention, as well as for its possible age-fighting properties.

Customer Ratings & Reviews

Rated 4.5 out of 5 by 46 reviewers.
Rated 5 out of 5 by Great stuff Gained muscle from this product. Gives me a sharper mental edge and boosts my memory. Have been taking for two years with no negative side effects April 4, 2016
Rated 5 out of 5 by Best way to keep brain healthy I take pregnenolone every morning. I follow the Ray Peat diet and this supplement combined with a no grain diet makes me feel wonderful. No brain cloud or fog and my memory is on track. Without it I can't remember names or if I took my pills. Best supplement to keep your brain young and supple. April 29, 2015
Rated 5 out of 5 by SwansUltraSuprStrngthPreg Buying this from Swanson is less expensive than getting it mixed into my compound. The capsule size is not difficult to swallow & the price is great. March 3, 2015
Rated 3 out of 5 by Be careful with this product I bought and used the 10 mg. Swanson pregnenolone and wrote a favorable review. I am not sure how to revise or update my review and if that is even possible, but I wanted to caution others in case they had the same reaction that I did. At first, this supplement in the 10 mg. strength really seemed to help balance out my hormones. But as the weeks or months went on, I noticed that I was "revved up" too much: my blood pressure was up and I was irritable and my periods actually disappeared. I stopped the pregnenolone and my blood pressure went back to normal but my periods have not returned yet and it's been 2 1/2 months. I am very sensitive to supplements and hormones, but in case others are too, I just wanted to write this review to let you know to proceed with caution and preferably, guidance from your doctor or nurse. I think this would be a great supplement for older, post-menopausal women, and I may try it again once I reach that stage. But it is potent and it is to be used with medical guidance and caution. September 29, 2014
Rated 4 out of 5 by I try to do something for my brain but I do not know if it is working. July 2, 2014
Rated 5 out of 5 by 10 Stars Five stars is not enough. Many of the Swanson brand products we've tried seem more potent than those of other brands. This pregnenolone is one of those with great quality & effectiveness. I find it helpful for a sense of general well-being. I wish I could make a statement about this supplement & my medical situation, but it seems that is prohibited here. When you add effectiveness onto the great prices, excellent customer service & speedy delivery, the repeat orders of this product have been a no-brainer for me. May 17, 2014
Rated 4 out of 5 by Take this with DHEA I find this makes the DHEA I take more effective. I have noticed more energy and endurance when taking this. I would not say it is miraculous but it has been a significant improvement. I will continue to take this. April 20, 2014
Rated 5 out of 5 by 100mg daily staple Pregnenolone is a daily supplement for me, 100 mg. At my age I'd take more if it cost less. That said, Swanson charges less than most places. February 16, 2014
Rated 5 out of 5 by Great product! I started using this several years ago to help with middle-aged forgetfulness and foggy mindedness - it has worked very well for me. I ran out of this a few months ago and realized after a week or so how much this was really helping me, so I quickly reordered more! November 21, 2013
Rated 1 out of 5 by No rise in my lab numbers I have been taking this product for over a year. My labs actually went down, even when I added 50 mg a day. My doctor has had over 400 people have no good results with this product. I am switching to a new brand. Melanie October 22, 2013
Rated 5 out of 5 by A product you can trust I use Swanson Ultra-SuperStrength Prenenolone because it is safe and effective. My levels were very low prior to using product and now are at an optimal level. August 21, 2013
Rated 4 out of 5 by Very helpful Have an overall good feeling after using this product July 10, 2013
Rated 5 out of 5 by improved my memory and relaxation I love what it did for my memory. Because I experience greater relaxation after taking it, though, I make sure to take it after my morning coffee or right before bed. June 1, 2013
Rated 4 out of 5 by I was on a brand that cost almost 3 times as much and when they closed I went to this and it seems to do just as well. April 15, 2013
Rated 4 out of 5 by booster for aging people At my age, I feel a booster tonic is helpful. And this is it. I definitely feel better by using this product. March 28, 2013
Rated 5 out of 5 by Great price Cheapest I have ever found pregnenolone, and with the least fillers. March 12, 2013
Rated 4 out of 5 by Can't tell if supplement is working Seldom can feel a difference, however having the precursors to hormones available for a body to use seems reasonable, especially after menopause. March 12, 2013
Rated 5 out of 5 by One a day . . . One of these a day, helps to keep my body in balance. I have been taking this for a couple years, and find that I feel better, if I take this every day. March 10, 2013
Rated 5 out of 5 by Swanson's Preg Very good product. Helps with fatigue and stress. The Swanson brand is a very good value. February 28, 2013
Rated 4 out of 5 by a needed nutrient I have read in Dr. Eric Braverman's book Younger Brain Sharper Mind that this nutrient and DHEA are needed to help us stay sharp as we age. I have been taking one capsule at breakfast and one at lunch for about a month and don't see any marked difference as yet. The lable suggests one a day but that wasn't doing much so I added the extra dose. It may be working subtely and I just don't don't detect it so I'll stick with it for another month. Doesn't hurt and hopefully will help. I also take the DHEA as the doctor suggested. February 28, 2013
Rated 5 out of 5 by A great product I have been using pregnenalone for quite awhile. I take this and 7-keto DHEA and use progesterone cream, and I do believe I am feeling so much better. January 28, 2013
Rated 5 out of 5 by Huge Difference! Everyone is different, so I don't expect you to experience the same effect that I have with this product. Well, I literally stumbled on this product after reading about it on the internet (known as the "happiness hormone") and it has made a dramatic difference right away. In my line of work, Chemistry, I do tons of calculations each day. I don't feel as mentally fatigued throughout the day and I can run numbers through equations more fluidly and with fewer errors. This is a GREAT product! Potent and effective. January 2, 2013
Rated 1 out of 5 by Does NOT WORK In April, my pregnenalone lab value was 3 (optimal range 180-200). I started taking one of these each day from the end of April until the end of December. My labs at the beginning of April were still at 3 (optimal range 180-200). If taking 50mg of this each day for 8 months does not make a difference, I believe there may be a problem with the pills. I am going to try a different brand/manufacturer and see how that works. December 24, 2012
Rated 5 out of 5 by Didn't expect this result! Went to this super strength dose, and lo and behold my short term memory began to improve. Was also able to assimilate information more quick than before. You have to stay on a consistent regimen of taking it , though, but at these prices that's easy. Wish they offered a larger quantity size! September 30, 2012
