Jarrow Formulas Ashwagandha KSM-66

4.5/5

A standardized KSM-66 root extract at the dose used in most stress and cortisol studies — a sensible, well-tested first choice for adults over 50.

The best-evidenced adaptogens for adults over 50 are ashwagandha (for stress, cortisol, and sleep), rhodiola rosea (for fatigue and mental energy), and maca (for energy and libido, especially around menopause). Panax ginseng, holy basil, and eleuthero round out the list as supporting options. None of them is a magic pill — but used thoughtfully, the right one can take the edge off chronic stress or help you feel less drained.

This guide explains what an adaptogen actually is, which ones have real evidence behind them, who should be cautious, rough doses, and how to pick a product that isn’t a waste of money.

Important: This article is educational, not medical advice. Adaptogens can interact with prescription medications and affect thyroid, blood pressure, and blood sugar. Talk to your doctor or pharmacist before starting any adaptogen, especially if you take prescriptions or have a thyroid or autoimmune condition.

The short answer

  • Ashwagandha — best for stress, high cortisol, and sleep. Studied at 300-600mg/day of a standardized extract like KSM-66.
  • Rhodiola rosea — best for fatigue and mental energy. Around 200-400mg/day, standardized to 3% rosavins.
  • Maca — energy and libido, particularly helpful around menopause. Roughly 1,500-3,000mg/day.
  • Panax ginseng, holy basil (tulsi), eleuthero — reasonable supporting players with lighter or mixed evidence.
  • Quality matters more than the label hype. Choose standardized, third-party-tested extracts.
  • Safety first. Ashwagandha can affect thyroid hormone levels; adaptogens can interact with thyroid, blood pressure, blood sugar, sedative, and immune medications. Check with your doctor.

What is an adaptogen?

“Adaptogen” is an old term from herbal medicine for plants that may help your body cope with stress — physical, mental, or environmental. The idea is that they nudge your stress-response system back toward balance rather than pushing it hard in one direction like caffeine does.

In practical terms, the most-studied adaptogens appear to influence the HPA axis — the communication loop between your brain and adrenal glands that controls cortisol, your main stress hormone. When cortisol stays elevated for months, you can feel tired but wired, sleep poorly, and run low on energy. Adaptogens may help soften that pattern.

A fair word of caution: “adaptogen” is not a tightly regulated scientific category, and the quality of research varies a lot from herb to herb. Some, like ashwagandha and rhodiola, have a decent body of human trials. Others rest more on tradition than on rigorous data. So treat the label as a useful starting point, not a guarantee.

The best adaptogens for adults over 50

Here are the adaptogens worth knowing, ordered roughly by strength of evidence and relevance after 50.

Ashwagandha — the stress and sleep adaptogen

Ashwagandha (Withania somnifera) is the most-studied adaptogen for stress, and it’s the one I get asked about most. Several randomized trials have reported lower self-reported stress, reduced cortisol, and better sleep quality with a standardized root extract. People who feel anxious, overstimulated, and unable to wind down at night tend to respond best.

What it may help with: chronic stress, mild anxiety, racing thoughts, and unrefreshing sleep. Some men also use it for testosterone support, though the evidence there is more modest.

Rough dose: 300-600mg/day of a standardized root extract. KSM-66 and Sensoril are the two most-studied branded extracts. Effects usually build over 2-6 weeks.

Key cautions — read these carefully. Ashwagandha is in the nightshade family. It can raise thyroid hormone levels, so it should be used cautiously by anyone with a thyroid condition, and it may worsen autoimmune disease because it can stimulate immune activity. It is not recommended during pregnancy. There are also rare reports of liver injury — if you develop yellowing of the skin or eyes, dark urine, nausea, or unusual fatigue, stop taking it and see a doctor. Because of the thyroid and immune effects, talk to your doctor before starting, especially on thyroid, sedative, or immune-related medications.

Rhodiola rosea — the mental-energy adaptogen

Rhodiola (Rhodiola rosea) is the one to reach for when the problem is fatigue and mental fog rather than feeling wound up. It’s more activating than ashwagandha, and some studies suggest it may reduce mental fatigue and support stamina and concentration, particularly under stress.

What it may help with: daytime fatigue, low stamina, burnout-type exhaustion, and mental tiredness. Many people find it most useful taken in the morning.

Rough dose: 200-400mg/day of an extract standardized to about 3% rosavins and 1% salidroside (the two markers most trials use). Take it earlier in the day, since for some people it can be too stimulating before bed.

Key cautions: Rhodiola is generally well tolerated, but because it can be activating, it may worsen agitation or interfere with sleep in sensitive people. It may also interact with antidepressants and with medications affecting blood pressure, so check with your doctor if you take either.

Maca — energy, libido, and the menopause years

Maca (Lepidium meyenii) is a root from the Peruvian Andes, traditionally used for energy and stamina. It’s a bit different from the others — it doesn’t appear to act on cortisol the same way. Instead, small studies link it to improvements in energy, mood, and libido, with some of the most interesting findings around menopause.

What it may help with: low energy, low libido, and some menopausal symptoms such as mood and sexual well-being. It is not a hormone and does not replace hormone therapy.

Rough dose: 1,500-3,000mg/day of maca root powder or a concentrated extract. It’s often taken with food and may take several weeks to notice.

Key cautions: Maca is generally well tolerated. Because some lab evidence suggests possible hormone-related activity, anyone with a hormone-sensitive condition should check with their doctor before using it.

Panax ginseng — the classic energy tonic

Panax ginseng (Asian or Korean ginseng) is one of the oldest adaptogens in use. It’s traditionally taken for energy, stamina, and mental sharpness. The human evidence is mixed — some trials suggest modest benefits for fatigue and cognition, while others show little effect — so keep expectations realistic.

Rough dose: 200-400mg/day of an extract standardized to ginsenosides. It can be mildly stimulating, so take it earlier in the day.

Key cautions: Ginseng may lower blood sugar and can affect blood pressure, so people with diabetes or hypertension should be careful and involve their doctor. It can also interact with blood thinners such as warfarin. Avoid combining it with other stimulants.

Holy basil (tulsi) — a gentler option for stress

Holy basil, or tulsi (Ocimum sanctum), is a calming adaptogen used in Ayurvedic tradition for stress and general well-being. The research is smaller and more preliminary than for ashwagandha, but some studies suggest it may help with stress and mood. It tends to be gentle and is sometimes taken as a tea.

Rough dose: roughly 300-600mg/day of a standardized extract, or as a tea.

Key cautions: Holy basil may lower blood sugar and has mild blood-thinning potential, so use caution if you take diabetes medication or blood thinners, and let your doctor know.

Eleuthero — for stamina and recovery

Eleuthero (Eleutherococcus senticosus), once called “Siberian ginseng,” is traditionally used to support stamina and recovery from physical or mental strain. The evidence is limited and inconsistent, but it has a long history of use and is generally considered mild.

Rough dose: 300-1,200mg/day of a standardized extract.

Key cautions: Eleuthero may affect blood pressure and blood sugar and can be mildly stimulating. People with high blood pressure should be cautious, and it may interact with several medications — check with your pharmacist.

Cordyceps — a mushroom for energy and stamina

Cordyceps is a medicinal mushroom often grouped with adaptogens and marketed for energy, exercise performance, and stamina. Some small studies suggest it may modestly support exercise capacity, but the evidence in healthy older adults is thin. Think of it as an optional extra rather than a core choice.

Rough dose: 1,000-3,000mg/day of a cordyceps extract.

Key cautions: Because cordyceps may stimulate immune activity, anyone with an autoimmune condition or on immune-suppressing medication should avoid it unless their doctor approves. It may also have mild blood-thinning effects.

Who should be careful with adaptogens

“Natural” does not mean “safe for everyone.” After 50, more of us take daily prescriptions, and that’s exactly where adaptogens can cause trouble. A few groups should be especially careful — or avoid them entirely without medical guidance.

Thyroid conditions. Ashwagandha can raise thyroid hormone levels. If you have an underactive or overactive thyroid, or take levothyroxine, it can push your levels out of range. Don’t start it without talking to the doctor managing your thyroid.

Autoimmune disease. Several adaptogens — ashwagandha, eleuthero, and cordyceps in particular — may stimulate immune activity, which can be a problem if you have an autoimmune condition such as lupus, rheumatoid arthritis, or Hashimoto’s, or take immune-suppressing drugs.

Pregnancy and breastfeeding. Ashwagandha is not recommended in pregnancy, and most adaptogens lack safety data here. Avoid them unless your doctor specifically advises otherwise.

Medication interactions — the big one. Adaptogens can interact with blood pressure, blood sugar (diabetes), thyroid, sedative, and immune-suppressing medications, and some affect blood thinners like warfarin. If you take any prescription, the safe move is simple: ask your pharmacist or doctor to review the specific adaptogen before you start. Pharmacists do this all day and it costs you nothing.

A general rule: stop any adaptogen and call your doctor if you notice an unusual reaction — and for ashwagandha specifically, seek care for signs of liver trouble (yellowing skin or eyes, dark urine, persistent nausea, severe fatigue).

How to choose a quality adaptogen

The supplement aisle is full of adaptogen products of wildly different quality. A few simple filters separate the worthwhile ones from the junk.

Look for a standardized extract. Standardization means the product is guaranteed to contain a set amount of the active compounds — for example, ashwagandha standardized to a certain percentage of withanolides, or rhodiola to about 3% rosavins. Cheap raw powders that list only “ashwagandha root, 1,000mg” with no standardization may contain very little active compound.

Favor studied branded extracts. For ashwagandha, KSM-66 and Sensoril are the extracts used in most of the good clinical trials, so a product built on one of those is a reasonable bet. Buying the form that was actually studied is one of the easiest ways to improve your odds.

Insist on third-party testing. Independent testing (look for NSF, USP, or a published certificate of analysis) confirms the product contains what the label claims and is screened for heavy metals and contaminants. This matters especially for root and mushroom products, which can accumulate heavy metals from soil. Our explainer on what third-party tested actually means walks through the seals to look for.

Be skeptical of “adaptogen blends.” Products that cram eight herbs into one capsule usually contain a pinch of each — far below the doses used in research. You’ll generally do better with one or two well-dosed single ingredients than a kitchen-sink formula.

Check the dose against the research. Compare the per-serving amount to the studied ranges in this guide. If a product’s dose is far below them, it’s unlikely to do much regardless of how good the marketing looks.

The bottom line

Adaptogens can be a genuinely useful tool for stress and energy after 50 — but they’re a tool, not a cure, and the right choice depends on your problem. Reach for ashwagandha when stress and sleep are the issue, rhodiola when it’s fatigue and mental fog, and maca for energy and libido, especially around menopause. Ginseng, holy basil, eleuthero, and cordyceps are reasonable extras with lighter evidence.

Whatever you choose, buy a standardized, third-party-tested extract at a dose that matches the research, and give it a fair 6-8 weeks before judging it.

Most importantly: if you take any prescription medication — or have a thyroid or autoimmune condition — clear the specific adaptogen with your doctor or pharmacist first. Adaptogens interact with more common medications than most people realize, and a two-minute conversation can save you a real problem.

Frequently Asked Questions

What is the best adaptogen for stress and high cortisol?

Ashwagandha has the strongest evidence for stress and elevated cortisol. Several randomized trials have measured lower self-reported stress and reduced cortisol with a standardized root extract at around 300-600mg daily, and many people also report better sleep. It tends to suit those who feel 'wired but tired.' That said, ashwagandha can affect thyroid hormone levels and may stimulate the immune system, so anyone with a thyroid or autoimmune condition should check with their doctor first. It is not recommended in pregnancy.

Ashwagandha vs rhodiola — which one should I take?

They solve different problems. Ashwagandha is calming and is best for stress, anxiety, racing thoughts, and poor sleep — it gently lowers the body's stress response. Rhodiola is more activating and is better for daytime fatigue, low stamina, and mental fog, particularly when you feel drained rather than wound up. Some people take rhodiola in the morning and ashwagandha in the evening. If your main issue is stress and sleep, start with ashwagandha; if it is low energy and mental tiredness, start with rhodiola.

Are adaptogens safe for seniors and people over 50?

For most healthy older adults, well-chosen adaptogens are generally well tolerated at standard doses, but 'natural' does not mean risk-free. The main concerns are medication interactions and existing conditions. Adaptogens can interact with blood pressure, blood sugar, thyroid, sedative, and immune-suppressing medications, and people over 50 are more likely to take these. Ashwagandha in particular can affect thyroid levels and has rare reports of liver injury. Always review any new adaptogen with your doctor or pharmacist before starting, especially if you take prescriptions.

How long do adaptogens take to work?

Adaptogens are not stimulants, so do not expect a same-day jolt. Most research and clinical experience suggest you need consistent daily use for about 2-6 weeks before stress, sleep, or energy effects become noticeable. Rhodiola sometimes feels noticeable within a week or two for mental energy, while ashwagandha's calming and sleep benefits often build over a month. If you have seen no benefit after 8-12 weeks at an adequate dose, it probably is not the right fit for you.

Can I take adaptogens with my blood pressure or thyroid medication?

Only with your doctor's guidance. Several adaptogens can nudge blood pressure or blood sugar, and ashwagandha can raise thyroid hormone levels — which may add to the effect of thyroid medication or destabilize a dose that was previously stable. Ginseng and eleuthero may also affect blood sugar and blood pressure. None of this means you definitely can't use them, but it does mean your prescriber and pharmacist should sign off and may want to monitor your levels. Never adjust a prescription on your own.

Can adaptogens help with menopause symptoms?

Some may help with specific symptoms, though they are not hormone replacement. Maca has the most supportive evidence around menopause, where small studies link it to better energy, mood, and libido. Ashwagandha may help the stress, anxiety, and poor sleep that often accompany the transition. These are supportive options, not treatments for menopause itself, and they do not replace a conversation with your doctor about your overall plan. See our guide on managing menopause-related anxiety for more.
