Thorne's Heart Health Complex targets cardiovascular support, and its headline botanical delivers a real dose: **Hawthorn extract** at 350mg sits comfortably inside the 160–900mg range used in heart-function trials. You're also getting 200mg of **magnesium** in a well-absorbed malate form, within the clinical range for blood pressure and vascular tone, plus 95mg of potassium — right at the 99mg cap regulators allow in a supplement, since most potassium is meant to come from food. Across three capsules, the cardiovascular basics are covered at doses that actually do something.

**Taurine** is the volume ingredient at 900mg per three-capsule serving, an amino acid with solid research for heart and circulatory support at 1.6g and above. The label suggests taking the serving one to two times daily, so dosing it twice puts you at 1,800mg — squarely in the studied cardiovascular range. That twice-daily rhythm is the difference between partial and full benefit here.

The clear gap is **CoQ10**: at 45mg per serving you're well under the 100mg minimum used in cardiovascular and energy studies, and even two servings a day (90mg) leaves you just short. If CoQ10 is a main reason you're considering this — for statin-related support or daily energy — you'd want to add a dedicated 100–200mg CoQ10 product alongside it.
