Could my calcium supplement be stalling me?

[Atkin50]

Hi!
Being a newbie that just completed a mildly disappointing induction ( only 3 pounds lost - 1/2 inch of waist) I'm posting to other forums for menu review and troubleshooting, but one area of concern foe me is my cclcium supplement. After I added it day 3) weight seemed to jump back up and stall since. I'm using SOLARAY Calcium-Magnesium and although I asked the Health food store clerk for a low-carb compatible supplement...I'm suspect of her knowledge AND the base from which the clacium is derived. The label reads as follows:

Calcium (as calcium carbonate, calcium amino acid chelate) 1000mg
Magnesium (as Magnesium Oxide, Magnesium amino acid chelate) 500mg
Glutamic acid HCI 100mg

Other ingredients: Gelatin (capsule), Cellulose, Magnesium Stearate, Alfalfa, watercress, dandelion and parsley.

This next part is what red flags me:

"The minerals in this product are reacted with WHOLE RICE concentrate rather than 'ordinary' soy, yeast or milk proteins which are commonly used to chelate minerals. The special rice concentrate used by Solaray is seven times higher in amino acid content than ordinary rice and is preferred by many over soy."

If this product is unacceptable, what SHOULD I get on a low budget?
