Just at first glance..

Don't count on the magnesium oxide to provide anything.
The amount of aspartate would be very small...the makers use
cheap, non absorbable mag ox because historically it was acceptable at one time. But recent studies show it is not appreciably absorbed.

The A in the cod liver oil may compete for absorption with the D.
One of the videos I linked to explains this...that A receptors have recently been found to block D absorption.

There is probably not much B12 in that combo product. A better dose would be 1000mcg/day.

Many of us use separate products for the important nutrients and combos for the rest.
When you are up for buying more:

Methylcobalamin 1000mcg/day or 5000mcg/day Jarrow, not expensive

Now D3, 5000mcg (this is a new dose that just came out) or the 2000mcg and take 2. not expensive

Zinc-- best form is monomethionine... called OptiZinc. (Source Naturals) not expensive.. one a day

Jarrow's B-right for the other B complex.

Magnesium glycinate, or other chelate as you choose.

L-glutamine for the GI lining

Vitamin C---I recommend sustained release or Ester C.. 500mg a day.

Many of us use iherb.com (or Vitacost.com) as they supply quality brands at about 40% the retail in local stores. iherb gives free shipping over $60.

Make sure she is getting a good amount of protein daily.
The blood proteins carry the thyroid hormone around the body.
Poor protein intake leads to low proteins everywhere. If she doesn't like meat etc, a good whey protein smoothie will substitute for it. Some whey protein powders are casein free.(Designer Whey is one example, and it has glutamine in it.)
You can use soy isolate if you choose, if she can tolerate that.
Adequate protein will improve the hair, as well.

These are just some ideas. I really prefer to use some of the more crucial supplements separately. Using the online discount suppliers allows for this freedom without much increase in expense.
