Daily One and Daily Two Caps
(Twinlab)

Supplements Descriptions

By Gary F. Zeolla


NOTICE:  I no longer recommend either of these or any other mega-dose supplement. For details, see the article Folly of Mega-Dose Supplements. It is best to get your nutrients from food, not supplements, as discussed in my God-given Foods Eating Plan and Creationist Diet: Second Edition books. However, if you are intent on taking a mega-dose supplement, then either of these supplements would be better than most. Therefore, I have left the following description as it was when I was still taking these products.


Twinlab makes both a Daily One Caps and a Daily Two Caps product. This page describes and compares these two supplements.

Daily Two Caps

Twinlab's Daily Two Caps is a high potency multiple vitamin-mineral supplement. I have used this supplement at various times and have found it to be a high quality product. I like it for several reasons.

First, as the name implies, this multi it is designed for two doses each day. And I have always thought it is best not to take all of one's supplemental nutrients at once as the body can only absorb so much at once. 

Second, also as the name implies, the form of this multi is a capsule. I have found that capsules tend to be more easily dissolved and thus utilized than tablets.

Third, this supplement is especially high in the antioxidant nutrients. The amounts all fall within the ranges I give in the first edition of my Creationist Diet book for antioxidants if one wants to take them for their possible effect in reducing the risk of heart disease, cancer, and stroke.

Fourth, the forms of nutrients found in this supplement are highly absorbable forms, such as the zinc being in the form of zinc picolinate rather than the more common but less well absorbed zinc oxide form.

Fifth, two versions of Daily Two Caps are available: one with iron and one without. Women of child-bearing age will want to take the version with iron, but adult men and post-menopausal women will want to take the version without iron.

Sixth, the amount of zinc is rather high (30 mg), so a separate zinc supplement, like Twinlab's ZMA or Jarrow's Zinc Balance, is not necessary nor desirable.

However, this multi does not contain very much calcium or magnesium, so I would recommend supplementing with a separate calcium/magnesium supplement. Twinlab's Calcium Citrate Caps would be ideal for this purpose.

Daily One Caps

Twinlab also makes a Daily One Caps. As the name implies, it is designed so you only have to take one capsule a day. As such, the absorption would not be as great as with the Daily Two Caps. However, this can be remedied by simply opening the capsule and pouring out half of into say one's breakfast cereal, closing the capsule back up, and then taking it with another meal.

The amount of nutrients in it are identical to that found in the Daily Two Caps, except that the antioxidant nutrients (beta carotene, vitamin C, vitamin E), along with zinc are considerably lower. But these lower amounts are not very problematic.

The amount of beta carotene is still substantial, plus the Daily Ones also contains retinyl palminate (preformed vitamin A). And you can easily add more vitamin C with a product like Twinlab's C-500 Caps. If only one a day is taken, as with the Daily One Cap, absorption will be increased if it is split between two meals.

Also, with less vitamin E, this opens the way to using a product like Twinlab's Super E Complex. This product has 400 IUs of mixed tocopherols rather than just alpha tocopherol. This gives it greater antioxidant power than regular vitamin E products.

Moreover, having less zinc can be a plus. I have found that taking a product like Twinlab's ZMA or Jarrow's Zinc Balance at bedtime helps with sleep. But if you take these along with the Daily Two Caps, that would be too much zinc. Thus the Daily Ones are a better multi to take when using such products.

And finally, the Daily One Caps are considerably less expensive than the Daily Two Caps. That is why I have switched to using them, along with the above mentioned reasons. Even with the Super E Complex and C-500 Caps, together they are still less expensive than taking the Daily Two Caps.
