Hello Derek,
Your plan looks suitable and you can adjust it according to your horse's weight. Yes, beet pulp and alfalfa are high in calcium but at the amounts you're feeding, there is not concern about the extra calcium. Horses can safely tolerate a calcium to phosphorus ratio of up to 6 to 1.
Flaxseed meal does have an inverted calcium to phosphorus ratio and you could add it. However, I prefer that you do as you mentioned -- add Glanzen Complete , which is flaxseed meal based. This is because you'll get more benefit from the vitamins and minerals in Glanzen than you would by doing Accel plus flaxseed meal that you grind yourself. Grinding flax yourself is tedious and must be done daily because it can very easily go rancid.
Keep me posted!

Hi Derek,
Yes, certainly you can go with Glanzen instead of the Glanzen Complete. The only difference is that Glanzen Complete is well, more complete, but if your grass or hay is of good quality, the Glanzen will be fine.
PreOx is also flaxseed meal based, but because you feed less of it, the amount of omega 3 fatty acids are not as high. It is, however, an excellent source of antioxidants vitamin E and C as well as others, so it too can be used.
You will do your horse a service by choosing any of these supplements, so go with the one that suits your budget best.
All the best,
Dr. Getty
