HelloPharmacist Scorecard of Phytosterol Complex 667 by DC
Four independent checks of what is known — a summary of the available information, not a grade of the product itself.
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
The stated purpose hasn't been mapped to our evidence data yet.
Why this rating?
- We haven't mapped this product's purpose to our evidence data yet — it'll be graded on the next content refresh.
Most active ingredients list an amount, but at least one is hidden in a blend or missing.
Why this rating?
- The label discloses an exact amount for 4 of its 7 active ingredients.
- “Phytosterol Complex” is a proprietary blend — the label gives one combined amount (667 mg) without saying how much of each component you get.
- “Approximate Phytosterol Content” is listed as a grouped ingredient — the label doesn't break down how much of each component you get.
The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.
Why this rating?
- 1 of the 2 matched ingredients can interact with medications — Pectin.
- The most serious interaction on file is rated Moderate.
- Some involve high-stakes drug classes: heart-rhythm medications.
- For scale: 23 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.
Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.
Why this rating?
- We hold adverse-effect (side-effect) data for 2 of the 2 matched ingredients.
- Pregnancy & breastfeeding safety ratings cover 2 of 2.
- General safety write-ups exist for 2 of 2.
- Remember: this measures how much safety information exists. Thin data is not the same as being safe.
HelloPharmacist summaryPartially disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
Assessment coverage: 2 of 7 active ingredients matched to our full ingredient reviews (monographs). Based on the product label dated Apr 22, 2021.
This Scorecard evaluates available label information, ingredient evidence, and known medication-safety considerations. It does not independently verify product identity, purity, potency, contamination, or manufacturing quality. How these ratings are computed

For each ingredient in Phytosterol Complex 667 with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.
Citrus Pectin
Digoxin (Lanoxin)
Theoretically, pectin might reduce the absorption of digoxin, potentially decreasing its effectiveness.
A small clinical study shows that taking digoxin with a kaolin-pectin suspension reduces the absorption of digoxin by about 62%. It is unclear if these effects are due to pectin, kaolin, or the combination.
Lovastatin (Mevacor)
Theoretically, pectin might reduce the absorption of lovastatin, potentially decreasing its effectiveness.
Case reports suggest that concomitant use of pectin and lovastatin might reduce the cholesterol-lowering effect of lovastatin, possibly due to reduced intestinal absorption of lovastatin.
Tetracycline Antibiotics
Theoretically, pectin might reduce the absorption of tetracycline antibiotics, potentially decreasing their effectiveness.
A small clinical study shows that taking tetracycline with bismuth subsalicylate in a kaolin-pectin suspension reduces the absorption of tetracycline by about 34%. It is unclear if these effects are due to pectin, kaolin, bismuth subsalicylate, or the combination.
