Bests & Worsts Reviews from Amazon

SHORT REVIEW: Left Coast is a superb MCT oil—and I've tried many, including Brain Octane (which I also love). For me: Measurable blood ketone boost when I'm cycling OFF my ketogenic diet, brain fog clears up and strong memory & cognitive boost (I'm a health and psychology writer), and no GI side effects on an empty stomach. In "fractional fatty acid" composition, it's very similar to Bulletproof XCT at a much lower price. I've been using it daily for over 11 months now. Also: If you care about small-batched, high-quality-controlled sources of your foods and supplements, then family-owned businesses like Left Coast are worth supporting. Disclaimer: I am in no way affiliated with Left Coast or any resellers—just a guy who cares about the health of myself, my friends, and my family. LONG REVIEW FOR CONFIRMED BIO-HACKERS ONLY (C8 to C18 BREAKOUT COMPARISONS WITH SOME OTHER BRANDS I'VE USED): Left Coast MCT Oil (this product) C8 56% C10 44% With 1 Tb (tablespoon) of this plus 1 Tb butter in coffee, zero appetite for 4-5 hours. Perceptible boost from fatigue and brain fog, better short-term memory (about 13% when measured on luminosity's online app). When I'm OFF my HFLC (high fat, low carb) ketogenic diet, my Precision Xtra ketone blood meter shows 2-4 mmol/L over 0.5 baseline, after about 2 hours. Brain Octane Oil (Bulletproof) https://www.amazon.com/Bulletproof-Brain-Octane-Oil-Ounce/dp/B00R7FFYO8/ C8 100% This gives me about the same ketone boost (though for others I know, much higher than a C8/C10 blend like Left Coast), YMMV. XCT Oil (Bulletproof) https://www.amazon.com/Bulletproof-XCT-Oil-32-fl-oz/dp/B00R7FFR86/ C8 and C10 combined: (individual ratios not specified): 100% Very similar to the Left Coast product in terms of physical stamina, fatigue reduction, and mental clarity. NOW MCT Oil https://www.amazon.com/NOW-MCT-100-Oil-32-Ounce/dp/B0019LRY8A/ C8: 60% or more C10: 35-40% Other: 0-5% This does give me a similar ketone boost as Left Coast and Bulletproof XCT oil, but sometimes just a little stomach discomfort. Also, it raises my triglycerides (I use a Multicare IN blood meter for that). I don't know why. Sports Research MCT Oil https://www.amazon.com/gp/product/B00XM0Y9SE/ C8 Caprylic Acid 34% C10 Capric Acid 28% C12 Lauric Acid 29% (really a long-chain fatty acid, some say to avoid for GI issues, but may have benefits) Other (not listed): 9% This gives me a similar ketone boost as Left Coast MCT oil, but I've stopped using it mainly because I'm hoping that maximum C8 and C10 per serving in other products will help my brain and physical stamina more. And, from wikipedia, here's the fractional breakout of PLAIN OLD UNREFINED COCONUT OIL: Caprylic C8   7% Decanoic C10   8% Lauric C12 48% Myristic C14 16% Palmitic C16 9.5% Oleic C18:1 6.5% Other 5.0% Are all those non C8 & C10 fractions (Lauric, Myristic, Palmitic, Oleic) “bad?” Controversial topic to be sure. Authors like Bruce Fife ("The Coconut Oil Miracle") and Mary Enig (biochemist and author of "Eat Fat, Lose Fat") cite benefits to whole coconut oil (anti-inflammatory effects, microbiome balancing, anti-fungal and anti-bacterial effects against harmful microbes, etc.). I'll leave the conclusions here for you to make. Hope this helps, and sincerely wishing you health and well-being - Andrew in Boulder, CO.
