HelloPharmacist Scorecard of Premier Digest by Premier Research Labs
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.
What’s inside
Low disclosure
Premier Digest contains 11 ingredients, most of them digestive enzymes. The active components include protease, lipase, and lactase — enzymes that break down protein, fat, and milk sugar (lactose) respectively — along with several other enzyme ingredients (amylase, cellulase, invertase, diastase, pepsin, and Opti-pH Protease).
The formula also includes apple cider vinegar and noni, traditional digestive-support herbs. The product is made up primarily of these active ingredients, with inactive fillers like rice extract, potato dextrin, tapioca dextrin, cellulose, and water to form the capsule.
Does it work?
Strong evidence
The evidence for this product's ingredients is limited. Lactase is effective for lactose intolerance — if you can't digest milk sugar, this enzyme can help.
The other ingredients — protease, lipase, and apple cider vinegar — lack sufficient reliable evidence to rate their effectiveness for digestive or other conditions in our data. Noni's effectiveness is also not established in the research we hold.
If you're considering this supplement for a specific digestive complaint, talk with your pharmacist or doctor about whether the evidence supports it for your situation.
How safe is it?
Well-documented data
The digestive enzymes in this product (protease, lipase, lactase, and pepsin) are generally well tolerated in most adults, though some people may experience mild digestive upset. Protease and pepsin can rarely trigger allergic reactions in sensitive individuals.
Lactase is generally well tolerated when used as directed. Apple cider vinegar in food amounts is safe, but this product may contain larger doses; long-term heavy use has been linked to low potassium, bone loss, and (rarely) chemical burns if applied to skin.
Noni is generally tolerated in moderate amounts but carries a rare risk of liver injury. It also contains significant potassium, which can be a concern if you're on potassium-related medications.
During pregnancy, protease and pepsin should be avoided unless prescribed by your doctor. Lactase is likely safe in pregnancy.
Apple cider vinegar in food amounts is likely low risk, but check with your doctor before using supplement doses. Noni was traditionally used to cause abortion and should not be used during pregnancy.
During breastfeeding, protease, pepsin, and lipase have little safety data — ask your doctor or pharmacist before use. Lactase is likely safe, but check first.
Meds to double-check
Moderate interaction found
Before taking Premier Digest, double-check with your pharmacist or doctor if you take potassium-sparing diuretics, ACE inhibitors, or ARBs (blood pressure or heart medications containing potassium-saving diuretics, ACE inhibitors, or ARBs) — noni may raise potassium to unsafe levels. Also check if you take warfarin or other blood thinners, insulin, diabetes drugs, digoxin, ranitidine, or any drug known to stress the liver.
Altogether, these interactions span 600 individual medications.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with clinical evidence supporting its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
This enzyme blend may help if you have trouble digesting lactose, but the effectiveness of the other ingredients isn't well established. If you take blood pressure medications (especially ones that raise potassium), a heart medication like digoxin, insulin, diabetes drugs, the blood thinner warfarin, or anything to treat acid reflux, check your exact medications with the tool on this page before starting.
Talk to your pharmacist if you're pregnant, breastfeeding, or have liver disease.

Premier Digest by Premier Research Labs Drug Interactions
HelloPharmacist Interaction Report
Premier Digest by Premier Research Labs contains two ingredients with documented interactions: apple cider vinegar and noni.
The most serious concerns come from noni, which carries multiple Moderate-severity interactions. Noni may increase potassium levels when combined with blood pressure medications that preserve potassium (potassium-sparing diuretics, ACE inhibitors, or ARBs), raising the risk of high potassium (hyperkalemia).
It may also lower the effectiveness of the blood thinner warfarin, increase the risk of low blood pressure (hypotension) with blood pressure-lowering drugs, and theoretically increase risk of liver damage if taken with medications known to harm the liver.
Read the full breakdown — every affected drug type, severity by severity
Apple cider vinegar in this product carries Moderate interactions with diuretics (water pills), the heart medication digoxin, and insulin — all involving a potential drop in potassium levels. It also carries a Minor interaction with diabetes drugs, where it might add to their blood-sugar-lowering effect.
Additionally, noni has a Minor interaction with ranitidine (an acid-reflux medication), which it may cause to build up in your system.
Several ingredients in this product — amylase, cellulase, invertase, and diastase — could not be checked because we hold no data for them. The other checked ingredients (protease, lipase, lactase, and pepsin) show no documented interactions with medications.
Altogether, these interactions span 600 individual medications. Use the medication checker on this page to verify whether any of your prescriptions are affected before you start.

For each ingredient in Premier Digest 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.
Noni
Ace Inhibitors (Aceis)
Theoretically, combining noni and ACE inhibitors might increase the risk of hyperkalemia.
Noni juice contains significant amounts of potassium, about 6 mEq/100 mL juice. This may increase the risk for hyperkalemia when used in conjunction with ACE inhibitors, which can also increase potassium levels.
Angiotensin Receptor Blockers (Arbs)
Theoretically, combining noni and ARBs might increase the risk of hyperkalemia.
Noni juice contains significant amounts of potassium, about 6 mEq/100 mL juice. This may increase the risk for hyperkalemia when used in conjunction with ARBs, which can also increase potassium levels.
Antihypertensive Drugs
Theoretically, noni may increase the risk of hypotension when used in combination with antihypertensive drugs.
Preliminary clinical research suggests that drinking noni juice can reduce blood pressure in individuals with hypertension.
Hepatotoxic Drugs
Theoretically, taking noni with hepatotoxic drugs might increase the risk of liver damage.
There is concern that noni might cause hepatotoxicity in some patients. Advise patients against combining noni with potentially hepatotoxic drugs.
Phenytoin (Dilantin)
Theoretically, taking noni fruit juice concomitantly with phenytoin may lower phenytoin levels and increase the risk of seizures.
In one case report, an adult taking phenytoin for partial seizures experienced low serum phenytoin levels while taking noni juice 90-200 mL daily. Serum phenytoin levels increased after decreasing noni juice consumption; similarly, serum phenytoin levels decreased after increasing noni juice consumption. Some researchers believe noni juice may induce cytochrome P450 2C9 enzymes, which would decrease phenytoin levels, but this has not been well studied. Patients may need additional monitoring when starting or stopping noni juice supplementation.
Potassium-Sparing Diuretics
Theoretically, combing noni and a potassium-sparing diuretic might increase the risk of hyperkalemia.
Noni juice contains significant amounts of potassium, about 6 mEq/100 mL juice. This may increase the risk for hyperkalemia when used in conjunction with potassium-sparing diuretics, which can also increase potassium levels.
Warfarin (Coumadin)
Theoretically, taking noni juice concomitantly with warfarin might decrease the effectiveness of warfarin.
In one case, a 41-year-old patient stabilized on warfarin had a decreased international normalized ratio (INR) following consumption of a specific commercial noni juice product (Noni juice 4 Everything). While the patient was still taking noni juice, an increase in warfarin dose did not produce an increase in INR. However, it should be noted that this particular product contained extracts and derivatives from more than 115 components, many of which contained vitamin K. Furthermore, vitamin K was listed as a separate ingredient of the product, suggesting that the product was possibly fortified with vitamin K. It has not been verified that noni fruit alone contains a significant amount of vitamin K or interacts with warfarin.
Ranitidine (Zantac)
Taking noni fruit with ranitidine might increase the levels and clinical effects of ranitidine.
Clinical evidence shows that taking an aqueous extract of noni fruit 30 minutes prior to taking a single oral dose of ranitidine can increase the rate of absorption and plasma concentration of ranitidine.
Apple Cider Vinegar
Digoxin (Lanoxin)
Theoretically, concomitant use of apple cider vinegar with digoxin might increase the risk of cardiac toxicity.
A case of hypokalemia related to chronic use of apple cider vinegar has been reported. Theoretically, overuse of apple cider vinegar could decrease potassium levels, increasing the risk of toxicity with digoxin.
Diuretic Drugs
Theoretically, concomitant use of apple cider vinegar with diuretic drugs might increase the risk of hypokalemia.
A case of hypokalemia related to chronic use of apple cider vinegar has been reported. There is some concern that people taking apple cider vinegar along with potassium depleting diuretics might have an increased risk for hypokalemia.
Insulin
Theoretically, concomitant use of apple cider vinegar with insulin might increase the risk of hypokalemia.
A case of hypokalemia related to chronic use of apple cider vinegar has been reported. Theoretically, overuse of apple cider vinegar concomitantly with insulin might increase the risk of hypokalemia.
Antidiabetes Drugs
Theoretically, taking apple cider vinegar with antidiabetes drugs might increase the risk of hypoglycemia.
Apple cider vinegar might reduce fasting and postprandial blood glucose levels and decrease gastric emptying in people with diabetes. However, not all research agrees. Theoretically, it might have additive effects on glucose levels when used with antidiabetes drugs.
