it checks every box for clean, high-quality nutrition.
Size: 32 Fl Oz (Pack of 1)
The oil itself is completely flavorless, which makes it perfect for adding to my morning coffee, smoothies, or even drizzling over meals. It blends smoothly and gives me a steady, sustained boost without any jitters or crashes. The 32 fl oz size is also a great value and lasts a long time. If you’re looking for a pure, reliable MCT oil to support focus, energy, or a keto lifestyle, this one is a winner. I Highly recommended!

Seems to be a good product. Lid, not so much.
Size: 16 Fl Oz (Pack of 1)
This is my first experience with any MCT oil. Took my first tablespoon of this this morning on an empty stomach. After about five minutes I could feel that it had clearly gotten into my system. Was surprised it was so quick. Seems to be pretty potent. The lid is clearly made to help inject and blend the product into a beverage. You cannot squeeze the bottle gently enough to simply dispense the product into a measuring spoon. Probably blew a couple tablespoons down my sink before I finally just took off the lid and poured it. Many screw on lids are of a standard configuration and used across products. I'll have to try to find one on something else. With the product, I'm pretty happy.

Tasteless
Size: 16 Fl Oz (Pack of 1)
Mixes well enough into coffee. While it floats on the surface it also is effective as it is tasteless and I don't really notice it as I drink my coffee. It's an easy way to incorporate the health benefits.

Yup. It's MCT (AFAIK), and its affordable!
Size: 32 Fl Oz (Pack of 1)
Great stuff. Great price. Great bottle! Packaged well, and the bottle design is flawless. It comes with two caps, one traditional cap style, and one hinged with a functional pour spout that prevents getting oil ALL over the bottle and ultimately EVERYTHING else like some other brands I've used in the past. Can't beat the price. Unfortunately, I cannot give a qualitative review as to the quality, as my testing capabilities are limited and any attempt to do so would be highly speculative. However, there is nothing obviously different (good/bad) about this verses competitor products. I will be purchasing regularly! :) ---------Opinion/Observation on overall performance balance for the constrained budget. -------- I think that the largest gain/loss is going to be your overall dietary consumption of quality fats, and reduction in carbs consumed and removal of sugars . E.g, it doesn't matter if your consuming an "metabolically optimized C8 isolated MCT oil" in the morning if you loading up on low quality fats in the afternoon, or if your other ducks are out of line (read: sleep, exercise and greater diet). Your better off spending less on your MCT, and more on your other needs to optimize your equation. In my personal case, I find being able to liberally use a cheap MCT (Viva) in larger quantities dynamically as needed throughout the day to keep myself energized and focused on the task at hand is a much better solution for efficiency than having to "ration" out a C8 isolate. Though I probably spend just as much if not more by using it this way, by being able to consume at a higher quantity, overall performance is greater in this case. Additionally, when consuming with other foods and metabolic efficiency and flavour is not as paramount (or when coconut would taste good), I'll opt for a quality coconut oil, as its also marginally cheaper per ounce. (about 13-15$/32oz compared to 18-20$/32oz for MCT). I have used HealthWorks Coconut oil in the past, and it was absolutely delicious. I recently got Kirkland (as on inspection it seemed to have the same qualities) for pennies on the dollar; but it tastes burnt, so I'm not sure if it was a batch issue, warehouse storage, or simply there processing methods but its defiantly not up to par in a taste test. I'll most likely try Viva in the future, as I've been impressed with them so far. Takeaway: Great product if you like to use a lot of MCT! Just make sure your micros (vitamins and minerals) are in check if you exceed the 50% fat macro level. :)
