After deciding to explore Ayurveda seriously, I immediately faced a problem: the supplement shelf. Hundreds of options. Price ranges from $8 to $80 for ostensibly the same herb. Brands I had never heard of. Unverifiable claims. No way to know if I was buying actual medicine or expensive placebo or something actually dangerous.
I spent a month asking every practitioner I met the same question: how do you know if an Ayurvedic supplement is actually good? The answers were consistent. None of them were complicated. They just required knowing what to look for.
The Core Problem: Lack of Regulation
In the United States, supplements are regulated by the FDA under the Dietary Supplement Health and Education Act of 1994, or DSHEA. DSHEA is notably lenient. It requires that supplements be labeled truthfully. It requires that manufacturers do not make disease claims. But it does not require that supplements be tested for quality, purity, or efficacy before they go to market.
This means a manufacturer can: source ingredients cheaply without knowing where they come from; process them with no oversight; put anything on the label they want; and put it on the shelf with minimal regulatory friction. As long as they do not explicitly claim to treat disease, they can market almost anything.
Ayurvedic supplements sourced internationally have even less oversight. A product coming from India may have been manufactured in a facility with minimal food safety standards. The testing it underwent in India may or may not be legitimate.
This is the environment you are shopping in. It is not malicious on all fronts — many manufacturers are genuinely trying to make good products. But there is no way to know which ones without understanding what to look for.
What to Look For: The Technical Side
Certificate of Analysis (CoA): This is a document showing that a batch of a product has been tested for purity and potency by a third party. A legitimate supplement manufacturer should be able to provide this upon request. If they cannot, or if they act like it is unusual for you to ask for it, walk away. The CoA should specify: what was tested; what the tests were for; what the results were; and what lab did the testing.
Third-party testing: This matters. Not the manufacturer's internal lab. An independent lab. Look for testing from organizations like NSF International, USP, or Consumer Lab. These organizations have credibility and accountability. If a manufacturer tests their own products in their own lab, the incentives for accuracy are compromised.
Standardized extracts: For herbs where the active compound is known, standardized extracts guarantee a consistent dose of that compound. Ashwagandha should be standardized to withanolides (typically 5%). Curcumin should be standardized to curcuminoids (typically 95%). If you see a product that does not specify standardization, assume it is a variable-quality raw powder with an inconsistent dose.
Organic certification: This does not guarantee purity — organic farms can still have soil contamination — but it does mean the product was grown without synthetic pesticides and was inspected by a third party. Look for USDA Organic on the label.
Heavy metal testing: Given what we know about heavy metals in supplements, legitimate manufacturers specifically test for lead, mercury, arsenic, and cadmium. The CoA should explicitly list the results for these metals. If it does not, ask why.
Microbial testing: All supplements can accumulate bacteria, mold, or other microorganisms. Legitimate manufacturers test for E. coli, Salmonella, and total bacterial count. These tests should be in the CoA.
Allergen disclosure: The product should clearly state if it contains or is processed in a facility with common allergens — gluten, nuts, soy, dairy. This is both a safety issue and an integrity issue. If they are not transparent about allergens, they may not be transparent about other things.
What to Avoid
Suspiciously cheap prices: If ashwagandha or another supplement costs 80% less than comparable products from reputable brands, assume something is wrong. Either the extract is not actually standardized, or the sourcing is low quality, or the testing was skipped. You almost never get what you pay for. But you definitely do not get it when the price is too good to be true.
Proprietary blends: Some manufacturers list ingredients but not quantities, claiming the formula is proprietary. This is a major red flag. It means you have no way to verify that the active ingredient is actually present at a therapeutic dose. Avoid proprietary blends.
Disease claims: If a supplement claims it will treat, cure, prevent, or mitigate a disease, it is making an illegal claim under DSHEA. This suggests either that the manufacturer does not understand the law or that they are willing to break it. Either way, that is a signal of low integrity.
Vague sourcing: If a company cannot tell you where their ingredients come from, walk away. A good company will tell you: this ashwagandha comes from Rajasthan state in northwestern India, from farms we have been working with for 15 years, and we test every batch. If they say simply made in USA or imported from India without specificity, you cannot verify quality.
Amazon and iHerb supplements: Marketplace platforms have a counterfeiting problem. Many supplements sold on Amazon or iHerb are legitimate, but a significant percentage are counterfeits or low-quality products. The risk is not zero. If you buy from Amazon, at least buy from the manufacturer's own store page, not from third-party sellers.
Brands that are unwilling to answer questions: Email a manufacturer and ask specific questions: where are your ingredients sourced? What testing do you do? Can you provide a CoA? A legitimate company will answer. A company that ghosts you or gives vague non-answers is not worth your money.
What to Look For: The Integrity Side
Founder or practitioner backing: Is there an Ayurvedic practitioner involved in formulation? Does the founder have expertise? Banyan Botanicals is founded by practitioners. Himalaya has been making supplements for generations. Organic India works with Ayurvedic practitioners. The involvement of someone with actual expertise is a good signal.
Transparency about limitations: Good supplement companies will tell you what their products do and, more importantly, what they do not do. They will tell you who should not take them. They will provide realistic dosage and timeline information. They will not promise miracles.
Publishing full information: Look for companies that publish: sourcing information; testing results; practitioner recommendations; contraindications; and suggested use. The more information they publish, the more confidence you can have that they have nothing to hide.
Community reputation: Talk to people who have used the brand. Ask Ayurvedic practitioners what they recommend. Look at reviews that are specific and detailed rather than generic.
Trusted Brands That Actually Know What They Are Doing
Himalaya: One of the largest Ayurvedic supplement manufacturers with significant presence in Western markets. Strong sourcing in India. Published testing. Multiple product lines with different quality tiers. Affordable to moderate pricing. Available everywhere.
Banyan Botanicals: Founded by American practitioners with deep Ayurvedic training. Rigorous sourcing. Published CoAs available upon request. Moderate to premium pricing. Small company with strong integrity.
Organic India: Direct sourcing from Indian farms. Organic certification. Practitioner-formulated. Premium pricing but justified by sourcing and testing.
Yogi Tea: Western company but formulates with Ayurvedic practitioners. Focused on tea blends rather than powders or capsules. Organic certified. More accessible pricing.
Herb Pharm: Primarily Western herbalism but increasingly incorporating Ayurvedic formulations. Strong testing. Published information. Moderate pricing.
None of these are perfect. All have some product lines that are better than others. But all of them will answer questions, provide testing information, and make products that are actually what they claim to be.
How to Read a Label
When you pick up an Ayurvedic supplement, here is what you are looking for:
Active ingredient listed with amount: It should say Ashwagandha Root Extract 500mg, not just Ashwagandha proprietary blend.
Standardization information: It should say Standardized to 5% Withanolides or similar.
Dose and frequency: It should tell you to take 1 capsule twice daily or similar. If there is no dose recommendation, that is a red flag.
Other ingredients: These should be recognizable things like organic cinnamon, organic ginger, non-GMO cellulose capsule. If there are mysterious chemicals you cannot pronounce, question why.
Warnings and contraindications: A honest product will list what you should not take it with and what conditions contraindicate it.
Manufacturer and source information: There should be an address where you can contact them. A lot or batch number. A date when the product was made.
QR code or website: Many good manufacturers provide QR codes linking to batch-specific CoAs. This is increasingly common and increasingly valuable.
The Final Filter
After all of this, here is the simplest filter: if a company will not answer your questions, do not buy from them. Send an email. Call if you can. Ask specifically about testing, sourcing, and contraindications. See what they say.
A good company will respond within a few days. They will answer your questions directly. They will provide documentation. They will not act annoyed that you are asking.
A bad company will not respond, will respond vaguely, will act like you are being paranoid, or will not have information to provide.
That is your answer.
