HelloPharmacist Scorecard of Nourish Organic Vanilla Vegan Protein by System LS

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 2 of its 13 active ingredients.
  • “raw organic Sweeter Than Sugar” is listed as a grouped ingredient — the label doesn't break down how much of each component you get.
  • “RAW Organic Blend” is a proprietary blend — the label gives one combined amount (24,548 mg) without saying how much of each component you get.

This powder contains 12 ingredients, including several active proteins and functional compounds. The protein sources are organic pea protein, organic pumpkin protein, and organic sacha inchi protein, designed to support muscle and overall nutrition.

It also contains organic inulin (a fiber), organic stevia (a sweetener), organic spirulina and organic chlorella (nutrient-dense algae), organic goji berry extract, vanilla bean, and orange flavor for taste. Inactive ingredients are not listed separately for this product.

Does it work?

Strong evidence
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
Strong

Clinical evidence supports at least one of this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: weight loss and protein nutrition.
  • We looked for evidence on: Obesity, Diabetes, Impaired glucose tolerance (prediabetes), Dyslipidemia, Hypercholesterolemia, Hypertriglyceridemia — and 4 related terms.
  • The strongest evidence on file: Black Psyllium is rated "Effective" for Constipation (Natural Medicines).
  • Also on file: Inulin is rated "Possibly Effective" for Constipation, Diabetes, Obesity.
  • Also on file: Black Psyllium is rated "Insufficient Reliable Evidence To Rate" for Diabetes, Diarrhea, Obesity.

The evidence for most of these ingredients is limited or mixed. Pea protein's effectiveness for diabetes, exercise recovery, cholesterol, blood pressure, or IBS is not established in the data we hold.

Inulin shows possible effectiveness for weight management, constipation, and diabetes, though results vary. Stevia's effects on diabetes, blood pressure, and weight are not yet reliably proven.

Spirulina may be effective for high blood pressure, though safety concerns and contamination risk are noted. Chlorella shows possible effectiveness for pregnancy-related iron deficiency.

Goji berry effectiveness for heart disease, blood pressure, weight, or quality of life is not established. Overall, the protein content itself is the main nutritional draw; the added compounds lack strong clinical backing for specific health claims.

The evidence, ingredient by ingredient Black Psyllium Sodium Pea Protein Vanilla Blue-green Algae Chlorella

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 9 of the 9 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 9 of 9.
  • General safety write-ups exist for 9 of 9.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Sodium in normal food amounts is fine, but this product's sodium content matters if you're watching intake for heart or kidney health — check the label and discuss with your doctor if you're salt-restricted. Pea protein is generally well tolerated as a food-derived protein, though a small number of people with allergies to legumes (peanuts, tree nuts, chickpeas, lentils) have experienced allergic reactions including anaphylaxis.

Inulin commonly causes gas, bloating, and diarrhea, especially at doses over 30 grams. Stevia in food amounts is generally recognized as safe; most minor side effects (headache, dizziness, numbness) resolve after the first week.

Spirulina and chlorella quality varies widely and can be contaminated with toxins or heavy metals — the data advises caution or avoidance. Goji berry is generally safe as a food but has less safety data in concentrated supplement form; a small number of cases of liver injury and allergic reactions have been reported.

Vanilla in food amounts is well tolerated; allergic reactions are rare but possible.

Meds to double-check

Major interaction found
Known Interaction Concern · database check
Major identified

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 7 of the 9 matched ingredients can interact with medications — Black Psyllium, Stevia, Chlorella, Blue-green Algae, Goji, among others.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; diabetes medications; heart-rhythm medications; lithium.
  • For scale: 2,225 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.

If you take warfarin or other blood thinners (anticoagulants or antiplatelet drugs), this product is a concern — goji berry at Major severity and chlorella at Moderate severity may increase bleeding risk or reduce the drug's effect. Blood pressure medications (antihypertensives) interact at Moderate severity through sodium and goji.

Lithium interacts at Moderate severity with both sodium and stevia. Diabetes medications interact at Minor to Moderate severity with stevia, spirulina, and goji.

Heart rhythm drugs (flecainide) and immunosuppressants also warrant a conversation. Check your full medication list with your pharmacist before starting.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with clinical evidence supporting its stated purpose. Major medication interactions have been identified, and safety information is well characterized.

This product works best as a protein shake for general nutrition, though its added botanicals lack strong evidence for specific health benefits. If you take blood thinners like warfarin, blood pressure medications, lithium, diabetes drugs, or certain heart medications, talk with your pharmacist or doctor before using it — the sodium, goji berry, and other ingredients carry real interaction risks.

People with legume allergies should check ingredients and consider a patch test. For most others without medications, it's generally tolerable, though expect some bloating from the inulin.

Each ingredient & the kinds of drugs it affects

For each ingredient in Nourish Organic Vanilla Vegan Protein 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.

Dietary Fiber7 drug types · 2,025 drugs

Carbamazepine (Tegretol)

Theoretically, black psyllium might reduce the effects of carbamazepine and increase the risk for convulsions.
Theoretically, black psyllium might reduce carbamazepine absorption. A preliminary study using blond psyllium reported decreased carbamazepine bioavailability due to binding of the drug to psyllium, as well as reduction of available fluid in the gut for dissolution of the drug. This interaction may also occur with black psyllium.

Likelihood Probable Evidence D
Lithium

Theoretically, taking black psyllium at the same time as lithium might reduce lithium absorption.
The fiber in black psyllium might reduce lithium absorption and plasma levels. Some case reports describe a reduction in plasma lithium levels with concomitant administration of blond psyllium. This was reversed when psyllium was stopped. This interaction may also occur with black psyllium.

Likelihood Probable Evidence D
Metformin (Glucophage)

Theoretically, black psyllium might increase the therapeutic and adverse effects of metformin.
Animal research shows that concurrent consumption of blond psyllium with metformin slows and increases the absorption of metformin. This interaction may also occur with black psyllium. To avoid changes in absorption, take psyllium 30-60 minutes after metformin.

Likelihood Possible Evidence D
Olanzapine (Zyprexa)

Theoretically, taking black psyllium at the same time as olanzapine might reduce olanzapine absorption.
The fiber in black psyllium might decrease the absorption of olanzapine. A single case report describes a reduction in the effectiveness of olanzapine when it was concomitantly administered with an unspecified type of psyllium 3 grams orally twice daily. This effect was reversed when psyllium was stopped.

Likelihood Possible Evidence D
Digoxin (Lanoxin)

Theoretically, taking black psyllium at the same time as digoxin might reduce digoxin absorption and decrease digoxin levels.
Psyllium might bind digoxin in the gut. However, some clinical evidence suggests that psyllium does not impact digoxin absorption.

Likelihood Unlikely Evidence B
Ethinyl Estradiol

Theoretically, taking black psyllium at the same time as ethinyl estradiol might alter levels of estradiol.
Concurrent use of blond psyllium with ethinyl estradiol results in a slight increase in the extent of ethinyl estradiol absorption and a slower rate of absorption. This is unlikely to be clinically significant.

Likelihood Unlikely Evidence D
Oral Drugs

Theoretically, psyllium might increase, decrease, or have no effect on the absorption of oral drugs.
Psyllium seems to have variable effects on drug absorption. To avoid changes in absorption, take psyllium 30-60 minutes after oral medications. Animal research shows that blond psyllium delays and increases the absorption of metformin and ethinyl estradiol. Case reports and animal research suggest that blond psyllium might reduce absorption of lithium, digoxin, olanzapine, and carbamazepine. Finally, some pharmacokinetic studies show that psyllium does not affect the absorption of levothyroxine or warfarin. Although many of these studies evaluated blond psyllium, the fiber content in black psyllium may have similar effects.

Likelihood Possible Evidence B
Dietary Fiber full monograph & interactions

organic Chlorella2 drug types · 337 drugs

Photosensitizing Drugs

Theoretically, chlorella might have additive effects with photosensitizing drugs.
Chlorella has been reported to cause photosensitization. In five case reports, patients who had ingested chlorella exhibited swelling followed by erythematopurpuric lesions on sun-exposed areas of the body. Theoretically, concomitant use with photosensitizing drugs may exacerbate effects.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, chlorella might reduce the clinical effects of warfarin.
Chlorella contains significant amounts of vitamin K. There is at least one case report of warfarin therapy becoming sub-therapeutic after initiation of chlorella supplements.

Likelihood Possible Evidence D
organic Chlorella full monograph & interactions

organic Spirulina3 drug types · 327 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, spirulina blue-green algae might increase the risk of bleeding if used with other anticoagulant or antiplatelet drugs. However, this is unlikely.
Spirulina blue-green algae have shown antiplatelet and anticoagulant effects in vitro. However, one preliminary study in 24 patients receiving spirulina blue-green algae 2.3 grams daily for 2 weeks showed no effect on platelet activation or measures of clotting time.

Likelihood Unlikely Evidence D
Antidiabetes Drugs

Theoretically, taking blue-green algae with antidiabetes drugs might increase the risk of hypoglycemia.
Human research shows that spirulina blue-green algae can have hypoglycemic effects in patients with diabetes, at least some of whom were using antidiabetes drugs. However, blue-green algae does not seem to improve glycated hemoglobin (HbA1c) levels in patients with diabetes. A meta-analysis of animal studies also suggests that spirulina blue-green algae have hypoglycemic effects.

Likelihood Possible Evidence B
Immunosuppressants

Theoretically, concurrent use of blue-green algae might interfere with immunosuppressive therapy.
Blue-green algae have been shown to stimulate the immune system.

Likelihood Possible Evidence D
organic Spirulina full monograph & interactions

Sodium7 drug types · 205 drugs

Antihypertensive Drugs

Theoretically, a high intake of dietary sodium might reduce the effectiveness of antihypertensive drugs.
High intake of dietary sodium can increase systolic and diastolic blood pressure. Also, high intake of sodium may necessitate increased use of antihypertensive medications to achieve blood pressure control in some patients, such as those with chronic kidney disease.

Likelihood Probable Evidence A
Corticosteroids

Concomitant use of mineralocorticoids and some glucocorticoids with sodium supplements might increase the risk of hypernatremia.
Mineralocorticoids and some glucocorticoids (corticosteroids) cause sodium retention. This effect is dose-related and depends on mineralocorticoid potency. It is most common with hydrocortisone, cortisone, and fludrocortisone, followed by prednisone and prednisolone.

Likelihood Possible Evidence D
Didanosine (Videx)

Concomitant use of didanosine with additional sodium from dietary or supplemental sources may increase the risk of hypernatremia.
Didanosine formulations contain a significant amount of sodium.

Likelihood Probable Evidence C
Lithium

Altering dietary intake of sodium might alter the levels and clinical effects of lithium.
High sodium intake can reduce plasma concentrations of lithium by increasing lithium excretion. Reducing sodium intake can significantly increase plasma concentrations of lithium and cause lithium toxicity in patients being treated with lithium carbonate. Stabilizing sodium intake is shown to reduce the percentage of patients with lithium level fluctuations above 0.8 mEq/L. Patients taking lithium should avoid significant alterations in their dietary intake of sodium.

Likelihood Probable Evidence B
Sodium Phosphates

Theoretically, concomitant use of sodium phosphate with sodium supplements might increase the risk of hypernatremia.
Use of high doses (> 45 mL in 24 hours) of sodium phosphate, such as those used for bowel cleansing before surgery, can lead to serious electrolyte disturbances, including hypernatremia. The risk of hypernatremia is highest in the elderly and people with other risk factors for electrolyte disturbances.

Likelihood Possible Evidence D
Sodium-Containing Drugs

Concomitant use of sodium-containing drugs with additional sodium from dietary or supplemental sources may increase the risk of hypernatremia and long-term sodium-related complications.
The Chronic Disease Risk Reduction (CDRR) intake level of 2.3 grams of sodium daily indicates the intake at which it is believed that chronic disease risk increases for the apparently healthy population. Some medications contain high quantities of sodium. When used in conjunction with sodium supplements or high-sodium diets, the CDRR may be exceeded. Additionally, concomitant use may increase the risk for hypernatremia; this risk is highest in the elderly and people with other risk factors for electrolyte disturbances.

Likelihood Possible Evidence D
Tolvaptan (Samsca)

Theoretically, concomitant use of tolvaptan with sodium might increase the risk of hypernatremia.
Tolvaptan is a vasopressin receptor 2 antagonist that is used to increase sodium levels in patients with hyponatremia. Patients taking tolvaptan should use caution with the use of sodium salts such as sodium chloride.

Nourish Organic Vanilla Vegan Protein by System LS: Common Questions

Does Nourish Organic Vanilla Vegan Protein by System LS interact with any medications?
Yes. Based on its ingredients, Nourish Organic Vanilla Vegan Protein has a known interaction with 2,224 medications, including 2 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Nourish Organic Vanilla Vegan Protein contains 12 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.
Does this powder work for muscle building or recovery?
The product contains three plant-based proteins (pea, pumpkin, and sacha inchi) designed to support muscle nutrition. However, evidence for pea protein's specific benefit in exercise recovery is not yet established in the data we hold. It's a protein source, but results depend on your overall diet and training.
Will this cause bloating or digestive upset?
Yes, possibly. The inulin in this powder commonly causes gas, bloating, and diarrhea, especially if you're not used to it or if you have a large serving. These effects are more likely at higher doses. Start with a small amount and increase gradually if your stomach is sensitive.
Can I take this if I'm pregnant or breastfeeding?
Pea protein as a food is likely fine in pregnancy, though concentrated supplements haven't been well studied — talk with your doctor. Inulin is rated likely safe in pregnancy. Goji berry extract has limited safety data and traditional reports of uterine effects, so the data advises against medicinal amounts in pregnancy. For breastfeeding, similar caution applies — concentrated supplements lack reliable data. Check with your doctor or pharmacist for personalized advice.
Is it safe if I have a peanut or tree nut allergy?
Pea protein comes from peas, not peanuts, so it's a different plant. However, a small number of people with other legume allergies (to chickpeas, lentils, kidney beans) or tree nuts have experienced allergic reactions to pea protein, including anaphylaxis. If you have a history of legume or tree nut allergies, ask your doctor or pharmacist before trying it.
Why does the label mention so many algae and botanicals if they're not proven to work?
Spirulina and chlorella are nutrient-dense foods included for their micronutrient content, and goji is a traditional ingredient, but the evidence for specific health benefits is incomplete or insufficient. They're marketed for general wellness rather than proven medical claims. Focus on the protein content as the main nutritional benefit.
Is there a contamination or quality risk with this powder?
Spirulina and chlorella products can vary widely in purity and may contain heavy metals or toxins if not carefully sourced — the data flags this as a concern. The safety of the specific product you're buying depends on the manufacturer's quality control. Ask the brand about third-party testing if you're concerned.
