Reduces inflammation and puffiness!
I have noticed a reduction in inflammation. This is helping my joints, my stomach, and I'm hoping it will bring down my hematocrit. I get labs in October 2025. I started taking this in the end of April early May 2025 when my hematocritwas 45 (its been as high as 49 over the last few years and my doc wants me to keep an eye on it). My LDL is also elevated I can already tell this will be a staple for me. I haven't lost weight but I notice a lot of puffiness and swelling has gone down. It's helping my Crohns too! The pill is medium sized and easy to swallow. I think it's really effective and very inexpensive. I will try to update after October regarding my hematocrit and cholesterol.

A MUST for TRT. Lowers Hematocrit. Raises Ferritin. Incredible!!?
This has been a -- game changer -- for someone like me on TRT (testosterone). Google '1988', 'grapefruit' & 'hematocrit' on Goggle Scholar for a study to learn more. My hematocrit fell from 55 to 51 in one month. More importantly, my Ferritin rose from 29 to over 100! If you are on TRT, you should be aware that this is a COMMON (albeit largely unknown) problem. Sleep improved. Exercise recovery Greatly improved. This has been nothing less than a game changer for me. If you are on TRT and you don't take medication that interacts with grapefruit (btw. Talk to your doctor first!!), you should SERIOUSLY consider this supplement.

Works for me but
Worked for me as intended Pills are large and have a bitter flavor on the outside of the capsule but the benefits outweighs them.

Lowered hemocrait
I just happened to get blood work and noticed my white blood cells were high. My hemocrait was right at the limit as well. The doctor said let's check you again in 2 weeks (white blood cell related). I figured this would be a perfect time to see if it would lower my hemocrait since i was going to be getting blood work again shortly after. It dropped it 1.8 points in just 17 days. Oddly my white blood cells dropped a ton too but I don't think it's related to this.

Did not help my hematocrit at all
I don't know how to rate this because the product itself is fine, but it just doesn't do anything. I started taking this almost a year ago due to really high hematocrit. I faithfully took one capsule every day. I just got my levels checked and nothing has changed at all. Still the same numbers.

Helps weight loss
Research shows that this product helps weight loss. Not huge amounts. Maybe 1-2 pounds a month.
