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 4 of its 4 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Telomere Support contains 4 active ingredients: selenium, Setria (a form of glutathione), astragalus powder, and Resvinol. Selenium is a trace mineral that plays a role in antioxidant defense and thyroid function.

Glutathione is a compound your cells make naturally and is involved in detoxification and immune support. Astragalus is an herb used in traditional medicine for immune and energy support.

The product also contains inactive ingredients — cellulose, hypromellose, stearic acid, silica, and magnesium stearate — which are standard capsule fillers and binders.

Does it work?

Not established
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 established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use.

Why this rating?
  • The label markets this product for: Support telomere health and cellular aging.
  • We looked for evidence on: Aging, Cellular senescence, DNA protection, Chromosomal stability.
  • The closest evidence on file: Glutathione is rated "Insufficient Reliable Evidence To Rate" for Aging (Natural Medicines).

The evidence for this product's ingredients is mixed. Selenium is likely effective for treating selenium deficiency and possibly effective for Kashin-Beck disease, pre-eclampsia, and autoimmune thyroiditis — though the data suggests it may be ineffective for high cholesterol (dyslipidemia).

Glutathione is possibly effective for cisplatin-induced nerve damage but has insufficient evidence to rate it for Alzheimer's disease, fatty liver disease, athletic performance, or cataracts. Astragalus has insufficient evidence to establish its effectiveness for any of the conditions we have data on, including hay fever, asthma, and anemia.

We hold no effectiveness data for Resvinol.

The evidence, ingredient by ingredient Selenium Glutathione Astragalus

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.

Selenium is generally well tolerated in normal dietary amounts, but excess doses can be toxic — stick to the recommended dose and don't exceed 400 mcg daily without medical guidance. Side effects at recommended doses are usually mild (stomach discomfort, headache, rash), but high doses can cause hair loss, nail changes, nausea, and in rare cases organ damage.

Glutathione appears safe short-term orally but has limited long-term safety data; if inhaled, it can cause airway narrowing and shortness of breath in people with asthma. Astragalus is generally well tolerated short-term in healthy adults, though human safety data is limited.

There isn't enough reliable safety data for astragalus or glutathione in pregnancy or while breastfeeding — talk to your doctor or pharmacist for personalized advice.

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 — Astragalus, Selenium.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; diabetes medications; lithium.
  • For scale: 408 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.

Before you take Telomere Support, double-check with your pharmacist if you're on blood thinners or antiplatelet drugs (Moderate risk of increased bleeding), immune-suppressing medications (Moderate risk of reduced effectiveness), diabetes drugs (Moderate risk of low blood sugar), lithium (Moderate risk of increased lithium levels), barbiturates, warfarin (Coumadin), cyclophosphamide, birth control pills, or niacin supplements. These are the main medication types where documented interactions exist.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

Telomere Support is mainly for people interested in antioxidant and immune support, but the evidence for most uses is limited or mixed. If you take blood thinners, diabetes medications, immune-suppressing drugs, lithium, or barbiturates, you should check with your pharmacist before starting — selenium and astragalus can interfere.

Each ingredient & the kinds of drugs it affects

For each ingredient in Telomere Support 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.

Selenium6 drug types · 321 drugs

Anticoagulant/Antiplatelet Drugs

Selenium may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Clinical research suggests that taking selenium 10 mcg/kg/day can increase bleeding times by increasing prostacyclin production, which inhibits platelet activity. Other clinical research suggests that taking selenium 75 mcg daily, in combination with ascorbic acid 600 mg, alpha-tocopherol 300 mg, and beta-carotene 27 mg, reduces platelet aggregation.

Likelihood Possible Evidence D
Barbiturates

Theoretically, selenium might prolong the sedating effects of barbiturates.
Laboratory research suggests that selenium can inhibit the hepatic metabolism of barbiturates. Selenium seems to prolong the sedative effect of pentobarbital in animal models.

Likelihood Possible Evidence D
Immunosuppressants

Theoretically, selenium supplementation may reduce the effectiveness of immunosuppressant therapy.
In vitro research and preliminary clinical evidence suggests that selenium may stimulate the immune system.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, selenium might interfere with warfarin activity.
Animal research suggests that selenium can increase warfarin activity. Selenium might interact with warfarin by displacing it from albumin binding sites, reducing its metabolism in the liver, or by decreasing production of vitamin K-dependent clotting factors. Selenium can also prolong bleeding times in humans by increasing prostacyclin production, which inhibits platelet activity.

Likelihood Possible Evidence D
Contraceptive Drugs

Contraceptive drugs might increase levels of selenium, although the clinical significance of this effect is unclear.
Some research suggests that oral contraceptives increase serum selenium levels in women taking oral contraceptives; however, other research shows no change in selenium levels. It is suggested that an increase could be due to increased carrier proteins, indicating a redistribution of selenium rather than a change in total body selenium.

Likelihood Possible Evidence B
Niacin

Selenium might reduce the beneficial effects of niacin on high-density lipoprotein (HDL) levels.
A combination of niacin and simvastatin (Zocor) effectively raises HDL cholesterol levels in patients with coronary disease and low HDL levels. Clinical research shows that taking a combination of antioxidants (vitamin C, vitamin E, beta-carotene, and selenium) along with niacin and simvastatin (Zocor) attenuates this rise in HDL, specifically the HDL-2 and apolipoprotein A1 fractions, by more than 50% in patients with coronary disease. It is not known whether this adverse effect is due to a single antioxidant such as selenium, or to the combination. It also is not known whether it will occur in other patient populations.

Likelihood Possible Evidence A
Selenium full monograph & interactions

Astragalus, Powder4 drug types · 208 drugs

Antidiabetes Drugs

Theoretically, taking astragalus with antidiabetes drugs might increase the risk of hypoglycemia.
Clinical research in humans shows that astragalus might have hypoglycemic effects. Theoretically, taking astragalus, especially in combination with other hypoglycemic agents, might increase the risk of hypoglycemia.

Likelihood Probable Evidence A
Cyclophosphamide

Theoretically, astragalus might interfere with cyclophosphamide therapy.
Evidence regarding the effect of astragalus on immunosuppression caused by cyclophosphamide is conflicting. Some animal research suggests that astragalus reverses cyclophosphamide-induced immunosuppression. However, other animal research shows no effect.

Likelihood Possible Evidence D
Immunosuppressants

Theoretically, astragalus might interfere with immunosuppressive therapy.
Astragalus seems to stimulate immune function. Theoretically, taking astragalus might decrease the effects of immunosuppressive therapy.

Likelihood Possible Evidence D
Lithium

Theoretically, astragalus might increase levels and adverse effects of lithium.
Animal research suggests that astragalus has diuretic properties. Theoretically, due to this diuretic effect, astragalus might reduce excretion and increase levels of lithium.

How can one product interact with so many drugs?
Telomere Support 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.
Does selenium in this product interact with blood thinners like warfarin?
Yes — selenium may increase bleeding risk if you're on blood thinners or antiplatelet drugs, and it can theoretically interfere with how warfarin works. This is a Moderate interaction, so talk to your pharmacist or doctor before starting if you take any of these medications.
Can I take this if I'm on diabetes medication?
Astragalus in this product may lower blood sugar, so combining it with diabetes drugs could increase your risk of low blood sugar (hypoglycemia). Check with your pharmacist before taking it alongside your diabetes medication.
What does glutathione (Setria) do?

Is selenium safe at the dose in this product?
Selenium is generally well tolerated in normal dietary amounts and recommended doses. Just don't exceed 400 mcg daily without a doctor's say-so, since excess selenium can cause side effects like hair loss, nail changes, and nausea.
Is this safe to take while I'm pregnant or breastfeeding?
There isn't enough reliable safety data for astragalus or glutathione during pregnancy or breastfeeding, so talk with your doctor or pharmacist for personalized advice before starting.
