HelloPharmacist Scorecard of Rehmannia 1000 mg by Remedys Nutrition

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

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Sep 10, 2026

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains a single active ingredient: organic rehmannia at 1,000 mg per capsule. Rehmannia is a plant root used in traditional medicine, particularly in Chinese herbal practice.

The capsule itself is vegan.

Does it work?

Moderate 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

This product doesn't appear to be marketed for a specific use, so we graded Rehmannia's overall clinical evidence instead.

Moderate

Some clinical evidence supports Rehmannia for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredient's overall clinical evidence instead.
  • On file: Chronic kidney disease (CKD) — rated "Possibly Effective" (Natural Medicines).

Rehmannia is possibly effective for chronic kidney disease (CKD) based on available evidence. For other conditions — aplastic anemia, atopic disease, osteoporosis, diabetes, and diabetic nephropathy — the evidence we hold is insufficient to rate whether it works.

That doesn't mean it doesn't work; it means reliable human studies are lacking or the data isn't conclusive enough to say.

The evidence, ingredient by ingredient Rehmannia

How safe is it?

Some data gaps
Safety Information · database check
Some gaps

Safety data exists for these ingredients, but with some important gaps.

Why this rating?
  • We hold adverse-effect (side-effect) data for 0 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Rehmannia is generally used in traditional medicine, but human safety data are limited and quality varies significantly between products. The safety data advise against use during pregnancy and while breastfeeding because there isn't enough information to know it's safe in those situations.

No adverse effects were reported in the data we hold, though this doesn't guarantee none can occur.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and some safety-information gaps remain.

Rehmannia may be worth considering if you have chronic kidney disease and want to explore traditional remedies alongside your doctor's care. If you take blood pressure or diabetes medications, you'll need to check your specific drugs first — the risk of blood pressure or blood sugar dropping too far is real.

Talk with your doctor or pharmacist before adding this to your routine, especially if you're pregnant, breastfeeding, or managing blood pressure or blood sugar.

Rehmannia 1000 mg by Remedys Nutrition: Common Questions

Does Rehmannia 1000 mg by Remedys Nutrition interact with any medications?
Yes. Based on its ingredients, Rehmannia 1000 mg has a known interaction with 258 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Rehmannia 1000 mg contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism 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.
What is rehmannia used for?
Rehmannia is a plant root used in traditional medicine, particularly in Chinese herbal practice. In our data, it shows possibly effective evidence for chronic kidney disease. For conditions like diabetes, diabetic kidney disease, osteoporosis, and certain immune disorders, the evidence isn't established enough to say whether it works.
Can I take this if I'm pregnant or breastfeeding?
The safety data advise against rehmannia during pregnancy and while breastfeeding — there simply isn't enough information to know whether it's safe. Talk with your doctor or pharmacist about whether it's right for you in these situations.
What side effects has rehmannia been reported to cause?
No adverse effects were reported in the data we hold for this product. That said, human safety data for rehmannia are limited overall, and quality varies between products, so effects may exist that we don't have documented.
Why do I need to check my blood pressure and diabetes medications?
Rehmannia may lower blood pressure and blood sugar on its own. If you're already on medications that do the same thing, the combined effect could drop your blood pressure or blood sugar too far, which can be serious. That's why it's important to check your specific drugs with your doctor or pharmacist first.
How many active ingredients are in this product?
There's one active ingredient: organic rehmannia at 1,000 mg per capsule. The capsule itself is vegan and counts as an inactive ingredient.
