1. Well you know I will say both products are Excellent. It is basically, Spirulina / Bee Pollen vs. Alfalfa / Marigold. All 4 ingredients are super foods and known for their enormous health benefits. Marigold has also been proven as a natural medicine for several health conditions. It has been used for it's antiseptic, anti-inflammatory and anti-bacterial properties. Marigold also has ‘Lutein’, the yellow carotenoid pigment found in throughout the plant. This carotenoid has been know to fight cancer, and boost the immune system. Spirulina is know to Counteracting toxins in the body, Helping purify the liver, Increasing mental alertness, Lowering blood cholesterol and excess triglycerides, Helping fight viral infections, Treating radiation sickness, Enhancing ability to generate new blood cells, Improving blood sugar problems, Strengthening the nervous system, Strengthening the immune system, Removing toxic metals such as lead and mercury from the body, and Improving healing of wounds. Just to name a few.
2. I also use the Repashy Calcium Plus. I love using Repashy's calcium, it is a great product and it takes out the guess work and risk of OD. I use it daily in conjunction with my DinoFuel dustings. You can most certainly put DF on your bug burger to have your bugs eat it. Bug Burger has a lot of good ingredients in it and many forum members do this and love it. However, I simply put DinoFuel on a rinsed, organic, veggie or grinded nuts / seeds. The point of the DinoFuel is that it is a 100% Organic Super Food. It does not have any preservatives. Therefore, to put it on a product with un-natural preservatives kind of defeats the point.
3. Yes, I feed my insects and omnivorous reptiles DinoFuel and Yes, I dust my bugs too. Some forum members lightly wet superworms and dust the worms with DF. They say it makes it stick really well to the superworms.
Hope this helps - Tom
