Background
Fibroblast Growth Factor 21(FGF-21) is a member of the fibroblast growth factor (FGF) family and it is involved in the modulation of cell proliferation, growth, and differentiation as well as cell metabolism. This protein is a secreted endocrine factor that functions as a major metabolic regulator, and stimulates the uptake of glucose in adipose tissue. FGF21 binds to FGFR1c complexed with β-Klotho expressed in adipocytes to activate the canonical FGF signaling pathway (ERK1/2) and the AMPK/PGC1α pathway. Therefore, FGF-21 is being pursued as a therapeutic target for diabetes and obesity.

One of my favorites!
Size: 60 Count (Pack of 1)
It’s a very big bottle and has been my favorite for several months now. A lot of fish oil pills tend to be very uncomfortable to swallow but not these. I can swallow the single serving (2 capsules) at once which is not the case for most fish oil pills out there. I think these are definitely worth the money. Has definitely helped with my pain relief the past few months after being recommended to start taking this. I haven’t noticed too much in my skin health to be completely honest, i do a lot of other things with my skin and have a strict skincare routine already so i don’t think i would even really notice. I recently learned that fish can improve Skin health so it’s something i’ll look out for. The quality of the pills are great i’ve never once had one explode. Overall these are very effective. And they definitely affect your energy level in a positive way.

I should have read the label more carefully
Size: 60 Count (Pack of 1)
This seems to be a quality product, and I was initially happy to see that this is a one capsule dose (the main reason I ordered this brand). I was also pleased that the capsule size is small, especially compared to most fish oil capsules. What I wasn’t so happy about is the fairly minimal amount of Omega-3’s in each capsule (thus the smaller size). My bad - I should have looked at the label more carefully before ordering. I guess a person could take 3 or 4 a day to up the dosage, but that wouldn’t seem to be very cost effective.

Jaw breaker redesigned
Size: 90 Count (Pack of 1)
I want to thank the manufacturer for changing the design of this shape to an easier to swallow elliptical shape instead of the jaw breaker shape.
