First of all I'll admit that I've not ever owned or had any experience with an Eclectus, and I know little about their required diets/nutrition other than the very basics of the do's and don't's...that being said, after reading the ingredients of this "multi-supplement" and the claims that they make about it's effects, I'm not seeing the point at all, as long as your bird is getting a varied diet that consists of all of his daily nutritional needs (which is usually the case with any types of multi-supplements/vitamins/minerals/etc., unless they have some type of health/medical condition that causes or results-in a deficiency-syndrome or disease of some sort)...
Lots of B-Vitamins, along with the flax and chia, and then naturally-occurring amino-acids/digestive enzymes. So again, as long as Lincoln's regular daily diet is varied and includes all of the nutritional requirements that an Eclectus needs, then this supplement is totally unnecessary...All of the extra B-Vitamins will just be excreted by the bird because they'll be getting all of the B-Vitamins that their bodies can use from his food, and while it's true that Flax offers many health-benefits, if you think that Lincoln would benefit from them, then you'd be much better-off adding Flax Seed to his regular diet. As far as the amino acids/digestive enzymes, again, unless he is suffering from some type of GI issue or nutritional-absorption problem, then he's getting/making all of these he needs from his food as well. Now I do give my birds and my Bearded Dragon a Probiotic that also contains several naturally occurring Digestive-Enzymes, the same listed in this stuff, whenever they are put on an Antibiotic, and whenever my Dragon has an impaction-issue (common in Bearded Dragons if they eat too many live bugs with hard shells/exoskeletons), but again, that's a specific-supplement for a specific-situation...Nutrition is always absorbed better by the body when it comes from real sources of food....
