When I began tirz, I got blood work done at the same time. My LDL was 117, and my triglycerides were 219. I immediately switched to a clean, low-ish carb diet with healthy macros, started exercising, and, of course, took tirz. I also tried what I think was a "cheat code"... I took a supplement called "Cholestoff Complete" - took three pills after meals twice daily for a month. I drew labs again (only one month later), and my LDL was 79, and my triglycerides were 111. Sadly, my HDL dropped too, from 42 to 35. I haven't taken those pills since. This post reminds me I need to order labs again; it's been three months since my last check.
Anyway, if you're looking to take extreme measures, maybe look into Cholestoff Complete. Specifically, the "complete" version, as it lowers cholesterol and blocks excess cholesterol production in the liver. Active ingredients are plant stenols and pantethine. The diet and meds helped, but with such a quick change in just one month, I think the supplement deserves some credit.
Getting my HDL up is my main goal now... I've been taking omegas, exercising, and eating clean for years, so I'm not sure what else to do.
