HelloPharmacist Scorecard of A.C.S. (All Cells Salts) by Pure Herbs

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 4 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (1,846 mg) without saying how much of each component you get.

A.C.S. contains 4 active ingredients in a liquid form. Two of them—kelp whole algae extract and bladderwrack algae extract—are seaweed-based sources of iodine and minerals.

The product also includes arrowroot root extract (a starch source) and Irish moss extract (another iodine-containing seaweed). There are no other inactive ingredients listed.

Does it work?

Couldn't assess
Evidence for Intended Use · database check
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
Not assessable

We hold no graded evidence for this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: electrolytes and minerals for maintenance of good health.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

The evidence available to us doesn't establish that any of these ingredients work reliably for their traditional uses. Arrowroot carries insufficient reliable evidence for irritable bowel syndrome (IBS).

Kelp and bladderwrack show insufficient evidence for aging skin, heart disease, constipation, diarrhea, and indigestion. Irish moss also shows insufficient evidence for fatigue, muscle strength, chronic pain, quality of life, and iodine deficiency.

If you're considering this product for any of these purposes, talk with your pharmacist about whether the evidence supports it.

The evidence, ingredient by ingredient Arrowroot Fucus Vesiculosus Sea Moss

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

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 3 of the 3 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 3 of 3.
  • General safety write-ups exist for 3 of 3.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Arrowroot is generally well tolerated when used in food amounts, but there's limited safety data on medicinal doses—a clinical trial reported dyspepsia (indigestion), constipation, and dark stools in some participants. Use caution with concentrated or medicinal amounts.

Both kelp and bladderwrack are concerning during pregnancy and breastfeeding. The safety data advises against use in pregnancy because of excess iodine and possible heavy metal content.

During breastfeeding, the iodine passes into breast milk and may affect your baby's thyroid, so avoid it. When taken orally, both can cause goiter (enlarged thyroid), hyperthyroidism, and hypothyroidism—and in rare cases, thyroid cancer has been reported.

Irish moss is rated likely safe in pregnancy but should be avoided while breastfeeding due to unpredictable iodine levels and risk to the nursing infant's thyroid.

Side effects, ingredient by ingredient Arrowroot Fucus Vesiculosus Sea Moss

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 2 of the 3 matched ingredients can interact with medications — Fucus Vesiculosus, Sea Moss.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; lithium.
  • For scale: 892 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.

Check before taking this if you're on lithium, antithyroid drugs, amiodarone, or thyroid hormone replacements—the iodine in the algae can disrupt thyroid function and medication effectiveness. Also run it by your pharmacist if you take medications broken down by liver enzymes (CYP2D6, CYP2C9, or CYP3A4 substrates) or blood thinners (anticoagulants) or antiplatelet drugs, though those interactions are theoretical.

For each ingredient in A.C.S. (All Cells Salts) with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.

Kelp Whole Algae Extract9 drug types · 891 drugs

Amiodarone (Cordarone)

Theoretically, combining Fucus vesiculosus with amiodarone might cause excessively high iodine levels.
Fucus vesiculosus contains high concentrations of iodine. Amiodarone contains 37.3% iodine and can increase iodine levels. Concomitant use might increase the risk of having excessive iodine levels and adversely affecting thyroid function. Monitor thyroid function.

Likelihood Probable Evidence D
Antithyroid Drugs

Due to its iodine content, Fucus vesiculosus might alter the effects of antithyroid drugs.
Fucus vesiculosus contains high concentrations of iodine. Iodine in high doses has been reported to cause both hyperthyroidism and hypothyroidism, depending on the individual's past medical history. Taking Fucus vesiculosus while using antithyroid drugs could alter the effects of the antithyroid drugs.

Likelihood Possible Evidence D
Lithium

Concomitant use of Fucus vesiculosus and lithium has resulted in hyperthyroidism.
There is a case of hyperthyroidism occurring in a patient taking Fucus vesiculosus and lithium. Monitor thyroid hormones closely in patients taking lithium and Fucus vesiculosus concomitantly.

Likelihood Possible Evidence D
Thyroid Hormone

Due to its iodine content, Fucus vesiculosus might alter the effects of thyroid hormone.
Fucus vesiculosus contains high concentrations of iodine. Iodine in high doses has been reported to cause both hyperthyroidism and hypothyroidism, depending on the individual's past medical history. Taking Fucus vesiculosus while using thyroid hormone could alter the effects of thyroid hormone.

Likelihood Possible Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, taking Fucus vesiculosus with antiplatelet or anticoagulant drugs might increase the risk of bruising and bleeding.
In vitro evidence suggests that a constituent of Fucus vesiculosus, known as fucoidan, has anticoagulant effects. However, in clinical research, fucoidan does not seem to have significant anticoagulant activity when taken orally, possibly due to poor absorption.

Likelihood Unlikely Evidence D
Cytochrome P450 2C8 (Cyp2C8) Substrates

Theoretically, concomitant use of Fucus vesiculosus with CYP2C8 substrates might increase the risk for adverse effects.
In vitro research shows that fucoidan, a constituent of Fucus vesiculosus, inhibits CYP2C8. This interaction has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2C9 (Cyp2C9) Substrates

Theoretically, concomitant use of Fucus vesiculosus with CYP2C9 substrates might increase the risk for adverse effects.
In vitro research shows that fucoidan, a constituent of Fucus vesiculosus, inhibits CYP2C9. This interaction has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2D6 (Cyp2D6) Substrates

Theoretically, concomitant use of Fucus vesiculosus with CYP2D6 substrates might alter the effects of these substrates.
In vitro research shows that fucoidan, a constituent of Fucus vesiculosus, both inhibits and induces CYP2D6. This interaction has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, concomitant use of Fucus vesiculosus with CYP3A4 substrates might increase the risk for adverse effects.
In vitro research shows that fucoidan, a constituent of Fucus vesiculosus, inhibits CYP3A4. This interaction has not been reported in humans.

Likelihood Possible Evidence D

Irish Moss Extract3 drug types · 22 drugs

Amiodarone (Cordarone)

Theoretically, combining sea moss with amiodarone might cause excessively high iodine levels.
Amiodarone contains 37.3% iodine and can increase iodine levels. Concomitant use with sea moss, which contains approximately 4-7 mcg of iodine per gram, might increase the risk of adverse effects from iodine, including altered thyroid function.

Likelihood Possible Evidence D
Antithyroid Drugs

Due to its iodine content, sea moss might alter the effects of antithyroid drugs.
Sea moss contains approximately 4-7 mcg of iodine per gram. Iodine in high doses has been reported to cause both hyperthyroidism and hypothyroidism, depending on the individual's past medical history. Taking sea moss could theoretically alter the effects of antithyroid drugs.

Likelihood Possible Evidence D
Thyroid Hormone

Due to its iodine content, sea moss might alter the effects of thyroid hormone.
Sea moss contains approximately 4-7 mcg of iodine per gram. Iodine in high doses has been reported to cause both hyperthyroidism and hypothyroidism, depending on the individual's past medical history. Taking sea moss could theoretically alter the effects of thyroid hormone.

A.C.S. (All Cells Salts) by Pure Herbs: Common Questions

Does A.C.S. (All Cells Salts) by Pure Herbs interact with any medications?
Yes. Based on its ingredients, A.C.S. (All Cells Salts) has a known interaction with 891 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
A.C.S. (All Cells Salts) contains 4 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Can I take this if I'm pregnant?
No—the safety data advises against it. The iodine content and possible heavy metal concentration in the kelp and bladderwrack make them unsafe during pregnancy. Talk with your doctor about whether any ingredients might be appropriate for you.
Can I take this while breastfeeding?
The kelp and bladderwrack should be avoided—iodine passes into breast milk and may affect your baby's thyroid. Irish moss also carries insufficient safety data and poses a risk, so avoid it too. Ask your pharmacist or doctor if any part of this product is safe for you.
What does arrowroot do in this product?
Arrowroot is a starch source. The evidence available to us doesn't establish it works reliably for any condition, but it's generally well tolerated in food amounts. In medicinal doses, it may cause indigestion, constipation, or dark stools in some people.
What are kelp and bladderwrack?
Both are seaweed extracts rich in iodine and minerals. They're the main concern in this product—their high iodine content can disrupt thyroid function and interfere with thyroid medications or lithium. Variable iodine levels and possible heavy metals are additional safety worries.
What is Irish moss, and does it have the same concerns as kelp?
Irish moss is another seaweed extract, also high in iodine. It carries the same moderate interactions with thyroid and antithyroid drugs as kelp and bladderwrack. It's rated likely safe in pregnancy but should be avoided while breastfeeding.
Does this product actually help with anything?
The evidence available to us doesn't establish that these ingredients reliably treat any condition—all show insufficient evidence for their traditional uses, from fatigue to heart health to constipation. Talk with your pharmacist about whether there's a reason to try it.
