HelloPharmacist Scorecard of Wellstra Advanced by NewtonEverett

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

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 6 of its 6 active ingredients.
  • “Folate” is listed as a grouped ingredient — the label gives one combined amount (222 mcg DFE) without saying how much of each component you get.

Wellstra Advanced contains six active ingredients. Vitamin B6 and Folic Acid are B vitamins that play roles in energy, nerve function, and cell growth.

Folate is another form of the B vitamin listed separately in the label. Dong Quai powder is an herbal extract traditionally used in Asian medicine.

Borage Oil powder is derived from borage seeds and supplies gamma-linolenic acid (GLA), a fatty acid. Wild Yam extract comes from wild yam root.

The capsule also contains inactive ingredients—hydroxypropyl methylcellulose, rice flour, vegetable magnesium stearate, and silicon dioxide—which are fillers and binders that help deliver the actives.

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: Women's health and menstrual support.
  • We looked for evidence on: Dysmenorrhea, Folate deficiency, Anemia, Atopic dermatitis (eczema), Anxiety, Depression — and 3 related terms.
  • The strongest evidence on file: Vitamin B6 is rated "Effective" for Sideroblastic anemia (Natural Medicines).
  • Also on file: Folic Acid is rated "Effective" for Folate deficiency.
  • Also on file: Vitamin B6 is rated "Possibly Effective" for Premenstrual syndrome (PMS).

The evidence for this product's ingredients varies widely. Vitamin B6 is effective for sideroblastic anemia and B6 deficiency, and likely effective for high homocysteine levels; it's possibly effective for pregnancy-related nausea.

Folic Acid is effective for folate deficiency and likely effective for preventing neural tube birth defects and reducing methotrexate toxicity. Dong Quai, Borage Oil, Wild Yam, and Chaste Berry all show insufficient or possibly ineffective evidence for the conditions most commonly claimed.

We hold no effectiveness data for Chaste Berry in our system.

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 6 of the 6 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 6 of 6.
  • General safety write-ups exist for 6 of 6.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Vitamin B6 is well tolerated at doses under 100 mg daily but can cause nerve damage (sensory neuropathy) at high doses over time or with prolonged use. Folic Acid is generally safe at recommended doses and considered safe during pregnancy and breastfeeding at standard prenatal levels.

Dong Quai can increase bleeding and cause skin sensitivity to sunlight; safety data advises against use during pregnancy and while breastfeeding. Borage Oil seed that is certified free of pyrrolizidine alkaloids (PAs) is generally well tolerated, but other borage plant parts can harm the liver; it's unsafe in pregnancy and breastfeeding.

Wild Yam is likely fine for short-term use but long-term safety isn't well studied; avoid during pregnancy and breastfeeding due to insufficient data. Chaste Berry safety data is not on file.

Major identified

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

Why this rating?
  • 6 of the 6 matched ingredients can interact with medications — Borage, Vitamin B6, Dong Quai, Vitex Agnus-castus, Wild Yam, among others.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; Parkinson's medications.
  • For scale: 505 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 your medications against these drug types before starting: blood thinners and antiplatelet drugs (Major with Dong Quai, Moderate with Borage Oil), seizure medications (Moderate with Vitamin B6 and Folic Acid; Moderate with Borage Oil if you take phenothiazines), blood pressure drugs (Moderate with Vitamin B6), cancer medications including methotrexate, capecitabine, and 5-fluorouracil (Moderate with Folic Acid), amiodarone (Moderate with Vitamin B6), estrogen therapy (Moderate with Dong Quai and Wild Yam), and CYP3A4-inducing drugs (Moderate with Borage Oil). We could not check Chaste Berry against any medications.

Each ingredient & the kinds of drugs it affects

For each ingredient in Wellstra Advanced 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.

Borage Oil powder3 drug types · 226 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, borage seed oil may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
In healthy individuals, borage seed oil supplementation does not seem to affect platelet aggregation. However, gamma-linolenic acid, a constituent of borage seed oil, seems to decrease platelet aggregation by 45% and increase the risk of bleeding by 40% in animal and clinical research.

Likelihood Possible Evidence B
Cytochrome P450 3A4 (Cyp3A4) Inducers

Theoretically, taking borage with drugs that induce CYP3A4 might increase levels of pyrrolizidine alkaloid (PA) toxic metabolites.
Although borage seed oil contains little to no PAs, some borage plant parts, such as the leaf, flower, and seed, can contain hepatotoxic PAs. Hepatotoxic PAs are substrates of CYP3A4, which converts these chemicals into toxic metabolites. Tell patients to avoid borage preparations that are not certified and labeled as hepatotoxic PA-free.

Likelihood Possible Evidence D
Phenothiazines

Theoretically, taking borage sed oil with phenothiazines might increase the risk of seizures.
Borage seed oil contains gamma-linolenic acid (GLA). There is concern that taking supplements containing GLA might cause seizures, or lower the seizure threshold, when taken with phenothiazines. This is based on limited data from two reports published in the 1980s. In one report, three patients with schizophrenia who had received phenothiazines developed EEG changes suggestive of temporal lobe epilepsy after starting treatment with evening primrose, another source of GLA. However, none experienced an actual seizure. In the other report, two patients with schizophrenia who were stabilized on phenothiazines developed seizures when evening primrose 4 grams daily was added. One of these patients had a prior history of seizures. It is unclear whether evening primrose had any additive epileptogenic effects with the phenothiazines, but there is no evidence that taking GLA-containing supplements alone can cause seizures.

Likelihood Possible Evidence D
Borage Oil powder full monograph & interactions

Vitamin B65 drug types · 210 drugs

Amiodarone (Cordarone)

Theoretically, vitamin B6 might increase the photosensitivity caused by amiodarone.
Despite initial case reports suggesting that pyridoxine may have a protective effect against amiodarone-induced photosensitivity, preliminary clinical research suggests that pyridoxine may actually exacerbate this adverse effect.

Likelihood Possible Evidence B
Antihypertensive Drugs

Theoretically, vitamin B6 may have additive effects when used with antihypertensive drugs.
Research in hypertensive rats shows that vitamin B6 can decrease systolic blood pressure. Similarly, clinical research in patients with hypertension shows that taking high doses of vitamin B6 may reduce systolic and diastolic blood pressure, possibly by reducing plasma levels of epinephrine and norepinephrine.

Likelihood Possible Evidence B
Phenobarbital (Luminal)

High doses of vitamin B6 may reduce the levels and clinical effects of phenobarbital.
Preliminary clinical evidence suggests that vitamin B6 200 mg daily can reduce plasma levels of phenobarbital, possibly by increasing metabolism. It is not known whether lower doses have any effect. Advise people taking phenobarbital to avoid high doses of vitamin B6.

Likelihood Possible Evidence D
Phenytoin (Dilantin)

High doses of vitamin B6 may reduce the levels and clinical effects of phenytoin.
Preliminary clinical evidence suggests that vitamin B6 200 mg daily can reduce plasma levels of phenytoin, possibly by increasing metabolism. It is not known whether lower doses have any effect. Advise people taking phenytoin to avoid high doses of vitamin B6.

Likelihood Possible Evidence D
Levodopa

Vitamin B6 may increase the metabolism of levodopa when taken alone, but not when taken in conjunction with carbidopa.
Vitamin B6 (pyridoxine) enhances the metabolism of levodopa, reducing its clinical effects. However, this interaction does not occur when carbidopa is used concurrently with levodopa (Sinemet). Therefore, it is not likely to be a problem in most people.

Likelihood Unlikely Evidence D
Vitamin B6 full monograph & interactions

Dong Quai powder3 drug types · 163 drugs

Warfarin (Coumadin)

Dong quai may increase the risk of bleeding when used with warfarin.
Case reports suggest that concomitant use of dong quai with warfarin can increase the anticoagulant effects of warfarin and increase the risk of bleeding. In one case, after 4 weeks of taking dong quai 565 mg once or twice daily, the international normalized ratio (INR) increased to 4.9. The INR normalized 4 weeks after discontinuation of dong quai.

Likelihood Probable Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, dong quai may increase the risk of bleeding when used with anticoagulant or antiplatelet drugs; however, research is conflicting.
Animal studies suggest that dong quai has antithrombin activity and inhibits platelet aggregation due to its coumarin components. Additionally, some case reports in humans suggest that dong quai can increase the anticoagulant effects of warfarin. However, clinical research in healthy adults shows that taking 1 gram of dong quai root daily for 3 weeks does not significantly inhibit platelet aggregation or cause bleeding. Until more is known, use dong quai with caution in patients taking antiplatelet/anticoagulant drugs.

Likelihood Possible Evidence D
Estrogens

Theoretically, dong quai may reduce the effects of estrogens.
Dong quai has estrogenic effects. Theoretically, concomitant use of large amounts of dong quai might interfere with hormone replacement therapy due to competition for estrogen receptors.

Likelihood Possible Evidence D
Dong Quai powder full monograph & interactions

Chaste Berry extract5 drug types · 121 drugs

Antipsychotic Drugs

Theoretically, vitex agnus-castus could interfere with the activity of antipsychotic drugs.
Vitex agnus-castus might interfere with the action of dopamine antagonists such as antipsychotic drugs due to its dopamine agonist effects.

Likelihood Possible Evidence D
Contraceptive Drugs

Theoretically, vitex agnus-castus could interfere with oral contraceptives.
Vitex agnus-castus might interfere with the efficacy of oral contraceptives due to possible hormone modulating activity.

Likelihood Possible Evidence B
Dopamine Agonists

Theoretically, vitex agnus-castus could interfere with dopamine agonists.
Vitex agnus-castus might potentiate the actions of dopaminergic agonists due to possible dopaminergic effects.

Likelihood Possible Evidence D
Estrogens

Theoretically, vitex agnus-castus could interfere with the activity of estrogens.
Vitex agnus-castus has hormone modulating activity that can interfere with the efficacy of hormone replacement therapy.

Likelihood Probable Evidence D
Metoclopramide (Reglan)

Theoretically, dopaminergic effects of vitex agnus-castus could interfere with metoclopramide.
Vitex agnus-castus might interfere with the action of dopamine antagonists such as metoclopramide due to its possible dopaminergic effects.

Likelihood Possible Evidence D
Chaste Berry extract full monograph & interactions

Wild Yam extract1 drug type · 41 drugs

Estrogens

Theoretically, wild yam might increase or decrease the effects of estrogen.
Wild yam root shows estrogenic and anti-estrogenic effects in vitro. Theoretically, wild yam might interfere with hormone therapy.

Likelihood Possible Evidence D
Wild Yam extract full monograph & interactions

Folic Acid7 drug types · 40 drugs

5-Fluorouracil

Theoretically, high doses of folic acid might increase the toxicity of 5-fluorouracil.
Increases in gastrointestinal side effects of 5-fluorouracil, such as stomatitis and diarrhea, have been described in two clinical studies when leucovorin, a form of folic acid, was administered with 5-fluorouracil.

Likelihood Possible Evidence D
Capecitabine (Xeloda)

Use of high-dose folic acid might contribute to capecitabine toxicity.
Clinical research suggests that higher serum folate levels are associated with an increased risk for moderate or severe toxicity during capecitabine-based treatment for colorectal cancer. Additionally, in one case report, taking folic acid 15 mg daily might have contributed to increased toxicity, including severe diarrhea, vomiting, edema, hand-foot syndrome, and eventually death, in a patient prescribed capecitabine.

Likelihood Possible Evidence D
Methotrexate (Trexall, Others)

Folic acid might reduce the efficacy of methotrexate as a cancer treatment when given concurrently.
Methotrexate exerts its cytotoxic effects by preventing conversion of folic acid to the active form needed by cells. There is some evidence that folic acid supplements reduce the efficacy of methotrexate in the treatment of acute lymphoblastic leukemia, and theoretically they could reduce its efficacy in the treatment of other cancers. Advise cancer patients to consult their oncologist before using folic acid supplements. In patients treated with long-term, low-dose methotrexate for rheumatoid arthritis (RA) or psoriasis, folic acid supplements can reduce the incidence of side effects, without reducing efficacy.

Likelihood Probable Evidence B
Phenobarbital (Luminal)

Folic acid might have antagonistic effects on phenobarbital and increase the risk for seizures.
Folic acid can have direct convulsant activity in some people, reversing the effects of phenobarbital and worsening seizure control. Monitor closely for increased seizure activity.

Likelihood Probable Evidence B
Phenytoin (Dilantin)

Folic acid might reduce serum levels of phenytoin in some patients.
Folic acid may be a cofactor in phenytoin metabolism. Folic acid, in doses of 1 mg daily or more, can reduce serum levels of phenytoin in some patients. Increases in seizure frequency have been reported. If folic acid supplements are added to established phenytoin therapy, monitor serum phenytoin levels closely. If phenytoin and folic acid are started at the same time and continued together, adverse changes in phenytoin pharmacokinetics are avoided. Note that phenytoin also reduces serum folate levels.

Likelihood Probable Evidence B
Primidone (Mysoline)

Folic acid might have antagonistic effects on primidone and increase the risk for seizures.
Folic acid can have direct convulsant activity in some people, reversing the effects of primidone and worsening seizure control. Monitor closely for increased seizure activity. Note that primidone also reduces serum folate levels.

Likelihood Probable Evidence B
Pyrimethamine (Daraprim)

Folic acid might antagonize the effects of pyrimethamine.
Folic acid can antagonize the antiparasitic effects of pyrimethamine against toxoplasmosis and Pneumocystis carinii pneumonia. Folic acid doesn't antagonize the effects of pyrimethamine in the treatment of malaria, because malarial parasites cannot use exogenous folic acid. Use folinic acid as an alternative to folic acid when indicated.

Wellstra Advanced by NewtonEverett: Common Questions

Does Wellstra Advanced by NewtonEverett interact with any medications?
Yes. Based on its ingredients, Wellstra Advanced has a known interaction with 504 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?
Wellstra Advanced contains 6 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.
Is it safe to take this during pregnancy?
Folic Acid at standard prenatal doses is recommended during pregnancy to help prevent birth defects. However, Dong Quai, Borage Oil, and Wild Yam are not recommended during pregnancy. There isn't enough safety data on Chaste Berry for pregnancy. Talk with your doctor or pharmacist before taking Wellstra Advanced if you're pregnant or planning to be.
Is it safe while breastfeeding?
Folic Acid is considered safe at normal recommended doses while breastfeeding. Dong Quai and Borage Oil are best avoided while breastfeeding due to insufficient safety data. We don't have breastfeeding safety information on file for Wild Yam or Chaste Berry. Check with your pharmacist or doctor before use.
Can high doses of this supplement cause side effects?
Yes. Vitamin B6 can cause nerve damage at high doses over time. Folic Acid at very high doses (15 mg daily or more) can cause confusion, sleep problems, and hyperactivity. Borage Oil may cause digestive upset like bloating and soft stools. High doses of Wild Yam may increase headache and fever. Stay within recommended dosing.
What does Borage Oil do in this product?
Borage Oil supplies gamma-linolenic acid (GLA), a fatty acid. The evidence for borage in treating eczema or other conditions is either not strong or not established in our data.
Does this product work for menopausal symptoms?
The ingredients in this product aimed at menopause—Dong Quai and Wild Yam—show either insufficient evidence or possibly ineffective ratings for menopausal symptoms in our data. Talk with your doctor about what's proven for your needs.
What's in this capsule besides the active ingredients?
The inactive ingredients are hydroxypropyl methylcellulose (the capsule material), rice flour, vegetable magnesium stearate, and silicon dioxide. These are standard fillers and binders used to help the supplement hold together and deliver the actives.
