As of Aug 2026, Unbox Health has independently lab tested and rated 3 HealthKart products across Omega-3 Supplements, Collagen Supplements, Vitamin D Supplements, Vegan Collagen, Fish Oil Capsules: 2 out of 3 were rated A or A+.
We bought every HealthKart product from the open market, with no brand involvement. Each HealthKart product was third-party tested at up to 3 NABL-accredited, FSSAI-approved labs and rated D to A+ on their label accuracy, toxicity and nutrition profile (for foods).
HealthKart had no influence on the product ratings. All ratings stay valid for only 12 months, and all lab reports are published on HealthKart’s product pages.

The safety of a product is determined by what is found in lab tests, not what the brand claims. At Unbox Health, we have independently sourced and lab tested HealthKart products at NABL-accredited, FSSAI-approved labs for heavy metals and other harmful toxins. Results are reflected in each product's Non-Toxicity Score, visible on each product’s page.
Many side effects in health products are typically linked to contaminants, heavy metals, or ingredients present at levels that exceed safe limits. At Unbox Health, we’ve independently lab tested HealthKart products at NABL-accredited labs to identify these exact risks. We do not provide medical advice. Our findings are captured in each product's Non-Toxicity Score, visible in each product’s page.
Genuine means the product contains exactly what the label declares. At Unbox Health, we independently lab tested HealthKart products at multiple NABL-accredited labs to verify label claims and assess their accuracy. Our label accuracy score reflects how closely each product matches its label. The findings are available in the product ratings above.
Independent lab testing means testing outside the brand's own facility, at accredited third-party labs. At Unbox Health, we’ve independently purchased HealthKart products, and lab tested them across a minimum of two NABL-accredited, FSSAI-approved labs. As per our methodology, results must converge across labs before being used in a product's rating. All test results and findings are available on the product-level ratings page.
FSSAI approval is mandatory for all supplement and food products sold in India, and HealthKart products fall under the same regulations. FSSAI sets the regulatory baseline. At Unbox Health, we’ve gone further by independently lab testing HealthKart products at NABL-accredited labs to verify whether actual content matches what is declared on the label. These findings (among others) determine each product's Unbox Health rating.
HealthKart products may be available on the brand's official website and authorised marketplaces including Amazon and Flipkart. Counterfeit food and supplement products are a known problem in India, so always purchase from verified channels and reputed sellers. Avoid third-party resellers or unverified sellers, as product authenticity cannot be guaranteed outside authorised sources.
HealthKart is an online supplement marketplace that sells multiple brands. HK Vitals is HealthKart's own private-label supplement brand sold primarily through the platform. They are separate — HealthKart carries brands like MuscleBlaze and ON; HK Vitals is their in-house product line. At Unbox Health, we rate individual HK Vitals products based on independent lab testing. See ratings above.
HK Vitals carries FSSAI registration and brand-declared quality claims, but these are self-reported. Independent third-party testing is what verifies those claims. At Unbox Health, we source HK Vitals products from retail and test them at NABL-accredited, FSSAI-notified labs without any brand involvement. Our ratings are based entirely on lab results. Check individual product ratings above for the full tested scores.
\### Question: Is HK Vitals collagen good?
\### Answer: Whether any collagen supplement is good depends on whether the product delivers the dose it claims on the label. At Unbox Health, we independently test HK Vitals collagen at NABL-accredited, FSSAI-notified labs to check if the labelled collagen amount matches actual content. The Label Accuracy Score on the product card above reflects what our testing found.
