30lbsby22, you can take one with each meal or take them both together. Just whatever is better for you. You can ask your doctor if you should take them. If you eat fish a few times a week, then you probably get all you need anyway. It's good for your heart, but it won't contribute to weight loss.
You don't need to buy theirs (I've heard they are mega-expensive). You can buy a brand such as Natrol at any drugstore. I pay less than $10 per bottle of 150 of Natrol purified fish oil capsules.
Don't bother with the Reduce Plus. LAWL reps are supposed to try to sell everything to you. That's their job. But all you need is the diet plan, and of course to exercise
The Reduce Plus contains CLA (conjugated linoleic acid) which has been shown to possibly help keep weight off if you take it during maintenance, but human studies have shown that it does not help with weight loss. If you are interested in trying CLA, you can buy it anywhere from 10 to 20 bucks.
