As a part of a normal and healthy diet, beef liver can definitely be of help.
It’s very high in protein, as well as in vitamins and minerals, making you crave less other foods as a result.
I will say this though, that the food version is more economical, making for the better choice should you be tight on cash.

I wouldn’t call beef liver supplements (or as food) a miracle of any sort though when it comes to weight loss, since there are loads of other foods and stuff you can eat or do that’ll have a much larger impact on this.
See How To Lose Weight Fast And Keep It Off Long-Term for inspiration and to truly lose that weight.
Either way:
Best Beef Liver Supplement For Weight Loss
And as for my favorite beef liver supplement (for all-purpose, not just weight loss), we have:
Beverly International Beef Liver Pills

These come in 500 pills, which is a lot, but needed if you’re using it for weight loss and not just daily nutrition.
Check out Best Beef Liver Supplement For Health (Grass-fed, Affordable) however for more on which supplement is the best.
Summary

Beef liver can aid with weight loss but only as a part of a healthy diet overall.
You can take it as a supplement as well (see product above).
Eat liver, get healthier.
