This multivitamin covers a wide range of vitamins and minerals, with a few meaningful doses. You're getting 2,000 IU of **Vitamin D3** (a well-absorbed form within the clinical range), 200mcg of **Selenium**, and 18mg of **Iron** — all at levels that can make a real difference if you're not getting enough from food. The B vitamins are each dosed at 50mg, which is solid for general energy support, though most are in budget forms your body has to convert before using.

The mineral side is more of a mixed bag. **Calcium** at 500mg is delivered as carbonate and **Magnesium** at 100mg as oxide — both among the least absorbable forms available. **Zinc** at 15mg hits the bottom of the clinical range but is also zinc oxide. You're absorbing meaningfully less than the label suggests for these three minerals.

The "Women's Proprietary Blend" (160mg total for collagen, resveratrol, CoQ10, and lutein) and the "Herbal Blend" (50mg split across 12 botanicals) are too small to deliver any clinical benefit — each ingredient gets just a few milligrams, far below studied doses. These look good on the label but won't do much for you.

This is not medical advice. Consult a healthcare provider before making changes to your supplement routine.

The score analyzes what's on the label: ingredient doses vs. studied ranges, chemical forms, evidence levels, and known interactions. It does not verify label accuracy or test for contaminants — for that, look for third-party certifications like USP or NSF.
