Background

Interferon lambda 2 (IFN-λ2), also known as IL-28A, is a member of the type III interferon family, which also includes IFN-λ1 and IFN-λ3. IFN-λ2 plays a crucial role in the innate immune response to viral infections and has been shown to exhibit antiviral activity against a variety of viruses, including hepatitis C virus, influenza virus, and others. It signals through the IFN-λ receptor complex, leading to the activation of JAK-STAT signaling pathways and the induction of interferon-stimulated genes (ISGs) that contribute to the antiviral defense mechanisms. IFN-λ2 is primarily produced by immune cells, such as dendritic cells and macrophages, in response to viral stimuli and functions as a key mediator of the host's defense against viral pathogens.

Good quality, but…
Size: 60 Count (Pack of 1)
Good quality supplement for the price. I started to take it for my joints as I have an auto immune disease. My only complaint is that in order to get enough EPA for it to be effective for that I have to take a minimum of two a day but when I do that it makes me a little dizzy and upsets my stomach. I’m not sure if that’s because I’m on high blood pressure meds and because I don’t have a gallbladder, so I just take one a day of it for general health. I may try another brand just to see if my body has the same response.

Dropped LDL by 38 at one year check up
Size: 60 Count (Pack of 1)
I am a 48 year old female weighing 126 lbs. I want to praise this product for reducing cholesterol levels. I have seen the cardiologist to be proactive since my dad died of heart disease and because it runs on both sides of the family. My cholesterol levels have been borderline high for several years but not to the point of needing medication. In April 2025 it was the highest levels so far. I had been eating healthy cereals and exercising at that time so I was surprised it had increased. I have taken this supplement daily for a full year without missing many doses. I just had my yearly check up on April 1, 2026, and my total cholesterol dropped by 37 and the bad LDL dropped by 38. I am very please with my results. All my levels were in the optimal range except the LDL and It was in the nearly optimal range per the Labcorp graph and total cholesterol was in the acceptable range. I have not exercised in 8 months and I eat a lot of fast food, so this product is the only explanation for the improvement. I also started the Megared CoQ10 about 5 weeks before my labs but it wouldn't be long enough to be that helpful yet. I am going to stay on the CoQ10 in addition to the Megared 4 in 1 product to see if it further lowers the LDL to the optimal range next year. In one year with no diet changes or exercise: Cholesterol total went from 228 to 191 LDL Cholesterol went from 161 to 123 The only thing I do not like about the product is the price but with those results I can't complain. It is worth it.
