Now Foods has low prices, in-house testing, and recently seems to be coming up with a line of 'tru' products that are closer to nature. Other than that I take mostly Twinlab and Enzymatic Therapy.
Also generally I prefer capsules, not tablets, to avoid binders and the general feeling of stones in my stomach. (Exceptions: sustained-release Alacer Super Gram II vitamin C, Krebs magnesium-potassium by Enzymatic Therapy, enterics, and sublinguals or chewable wafers.)
Generally however the problem with 'totally natural' dietary supplements is:
1. Some no-name company makes slippery claims which are not valid.
2. Or when done 'honestly' the doses may be very low as to be unfeasible. For example a 'natural B complex' may be no stronger than a liver pill or yeast which is even more natural...!
I personally stick with moderate doses, plus natural products, plus 'coenzymate' variations, plus eat a healthy diet.
For example a good multivitamin should have about 25mg/mcg of each B vitamin. Then instead of mega b complex, I take Coenzymate B complex by Source Naturals. This includes very low-dose 'predigested' forms, as added protection for the inevitable breakdown of processing as we age. If the processing capability of one essential nutrient slows down, then year by year this logically drags everything else with it like slow dominos. And I also take liver pills and bee pollen.
I.e. just my opinion, but usually 'totally natural' vitamins are very high priced and don't make much $ense. Better to take 1/2 or 2/3 dose of good quality standard multivitamins, then add spirulina, liver, sublinguals, etc. As for basic minerals nothing beats chewble calcium citrate wafers by Twinlab, plus Krebs magnesium-potassium by Enzymatic Therapy.
My favorite multivitamin is Adam by Now Foods. Advertised 'for men' because this contains saw palmetto which in my opinion is essential for every man over 21. (Every man over 21 has a gradually enlarging prostate. Don't wait until it's been enlarging for 30 years and you have a urinary problem.)
However saw palmetto is not only for men. It is a hormone balancer similar to black cohosh for women, and both of which are even included in some women's formulas.
Adam also has advanced antioxidants ALA, CoQ10, etc. Adam also has a suggested dose of 3/day. This makes it very flexible depending on your dosage needs and how well you are eating. You might do fine with 2/day and adding natural sources as I have suggested above.
