  • A unique fatty acid supporting healthy internal ecology*

  • A favorite among athletes as a quick energy boost*

  • Made famous by Dr. William Crook in his book "The Yeast Connection"

Caprylic acid was first popularized as a dietary supplement by Dr. William Crook, author of the famous book on internal ecology, The Yeast Connection. Today it's widely used as a companion to other effective supplements, such as acidophilus and FOS, for healthy microbial balance.* It's also gaining popularity among athletes, who appreciate it for its quick energy.* Caprylic acid is a medium-chain triglyceride (MCT), a type of lipid that is not digested in the gut, but rather in the liver, like carbohydrates. As such, they deliver quick energy--more than twice that delivered by glucose.*

Customer Ratings & Reviews

Caprylic Acid is rated 4.6 out of 5 by 35.
Rated 5 out of 5 by from Great Caprylic Acid I order this over the Now brand at another supplier, because it is cheaper and just as effective. When they raise the cost here, or are out of stock I just order Now. Both are about the same in quality but not cost.

Rated 5 out of 5 by from GETS THE JOB DONE Valuable wellness and immune system factor found in Coconut Oil. Handy to use in capsules. It's amazing all the things one can read about the awesome therapeutic value of Coconut Oil and its different inherent factors. Caprylic Acid is just one of those inherent factors. Dr. Crook's book "The Yeast Connection" really put Caprylic Acid on the map about 30 or 40 years ago. Swanson's product and price are very good.

Rated 4 out of 5 by from Not for energy Caprylic Acid and other medium-chain triglycerides are excellent sources of immediate energy, but this particular product is not for energy. Let me explain. When I consume MCTs for energy, I use about 30 to 40 grams of MCT liquid mixed into a protein shake. That delivers about 250 to 350 calories from MCTs that are burned very quickly. However, these soft gels only deliver somewhere between 600mg to 1g of medium-chain triglycerides per serving. From my experience, you would have to take almost half this bottle before you notice a significant improvement in energy. Some people take caprylic acid or other MCTs for digestive health, and they take it in a form that can be delivered into the intestines. The MCTs must be coated and protected until the oil reaches the intestines or else much of the MCTs will be absorbed and sent straight to the liver before it can improve intestinal health. I cannot speak to whether these soft gels will deliver the caprylic acid to your intestines, but I would discourage you from buying this product for energy. There are other MCT products with Swanson or sold on Swanson's website that will be helpful for energy.

Rated 5 out of 5 by from Punch yeast in the gut! Did you know that caprylic acid is not friendly to certain kinds of yeast? They don't quite get along. Although I cannot say what kind of specific medical conditions that this stuff could address due to governmental regulations on posting them here online, I can say that caprylic acid 'busts a cap' in the knee of fungal yeast. I use caprylic acid as a deterrent to yeast-related issues that may occour from certain foods, like bread made with.......... I don't know.........YEAST, and sugary snacks. And although I would suggest healthy eating in general, sometimes I do not. Do you? In all seriousness though this stuff has worked for me, is fairly priced, comes in a light-protective brown plasic bottle; and is in a liquid form, which I prefer. I would suggest taking caution with any new supplement, especially with what this stuff is capable of. There can be possible side-effects if too many yeastie-beasties 'bite the dust' all at once in your body. I wish I could say what. Look it up if you want to, or speak with a knowledgeable person and/or health care practitioner as well. Overall, I am very happy with this product, I take it routinely and have been impressed so far. 5 leaves in satisfaction. :)

Rated 1 out of 5 by from Noticed no difference I noticed absolutely no difference in taking these, good or bad. Convenient enough to take the gelcap, but since it didn't do anything for me, I won't be ordering again.

Rated 5 out of 5 by from Great Derivative of Coconut Oil! I love, love, love Swanson Ultra Caprylic Acid! I have not been able to find this product without it having other ingredients I do not just get Caprylic Acid and nothing else. I like to supplement my diet with coconut oil, and this just gives me that extra boost I need.

Rated 3 out of 5 by from No Energy Boost Buy this product because you need Caprylic Acid, not because of the claimed energy boost. I find the claim that it provides a faster energy boost than glucose to be untrue.

Rated 5 out of 5 by from Using Caprylic Acid Swanson's Caprylic Acid softgels are convenient and easy to use. From my own experience I find that taking them with food seems to help them work even better.

Rated 5 out of 5 by from Totally Awesome! This stuff is great. Taken with the Ultimate Probiotic Formula and Bioperine, I got the best energy boost from a supplement that I've ever had. I have tried nearly everything and this stuff really works.
