Frequently Asked Questions
What is the standard particle size for the cracked-cell chlorella?
Our chlorella spec is 8-12 microns post mechanical bead-mill rupture, with the cracked-cell rate verified at 85-95% under 400x microscopy on every lot. Uncracked chlorella typically measures 2-8 microns, so the 8-12 micron range and the documented rupture rate together substantiate the cell-content bioavailability claim that uncracked product cannot make.
Do you provide a sample COA before production commits?
Yes. The pilot batch (20-30 units) is produced on the same ribbon-blender line as full production and ships with a complete ISO 17025 third-party COA covering identity (HPTLC fingerprint), potency (HPLC-DAD on standardized actives), heavy metals (ICP-MS to USP <2232>), pesticides (GC-MS / LC-MS/MS on a 280-compound panel), and microbiology (USP <61> and USP <62>). Clients review and sign off on the data before the production batch is released.
Which heavy metals are tested and what are the release limits?
Heavy metals are quantified by ICP-MS against USP <2232> elemental impurities limits: lead at or below 5 ppm, arsenic at or below 1.5 ppm, cadmium at or below 0.5 ppm, mercury at or below 0.5 ppm. These are tighter than FDA Total Diet Study action levels on lead and arsenic. California Prop 65 daily-exposure limits (Pb 0.5 ug, Cd 4.1 ug, Hg 0.3 ug) can be enforced as an additional release gate on request for brands selling into California.
How is the sennoside percentage in the senna leaf standardized and verified?
Senna leaf (Cassia angustifolia) is standardized to 6% sennosides A and B by validated HPLC-DAD assay against a pharmacopoeial sennoside reference standard. At a 50mg ingredient dose this delivers 3mg total sennosides per serving. Senna content language is structured under FTC structure-function compliance as 'supports occasional bowel regularity', not a laxative drug claim, which is the gating distinction between a dietary supplement label and an OTC monograph product.
What is the shelf life and what stability data supports it?
Shelf life is 24 months at room temperature in foil-laminated stand-up pouches or HDPE canisters. The claim is substantiated under ICH Q1A(R2) protocols with accelerated study at 40C / 75% RH for 3 months and long-term real-time study at 25C / 60% RH out to 24 months. Tracked stability indicators include moisture (Karl Fischer titration at or below 4%), silymarin potency (at or above 80% retention), sennoside potency, probiotic CFU survival, and chlorophyll degradation by spectrophotometry.
Can we add probiotics and what CFU survives processing?
Yes. The standard formula includes a 10-strain microencapsulated probiotic blend at 5 billion CFU at manufacture. The microencapsulation matrix is engineered for gastric-acid pass-through and ambient-stability, with the release spec guaranteeing at least 2 billion CFU at the 24-month expiry date. Probiotic survival is verified at T0, T3, T6, T12, and T24 timepoints on the long-term stability batch. Higher CFU counts up to 50 billion are available on custom formulations.
Are the structure-function claims substantiated for FTC compliance?
Yes. Every label claim on the master batch record is reviewed against the FTC structure-function claim framework and 21 CFR 101.93 disclaimer requirements. Substantiation files are assembled from peer-reviewed clinical literature on the standardized actives at the doses delivered (silymarin at or above 80% at 200mg, sennoside 3mg, dandelion 10:1 at 2,500mg dried-equivalent). The standard disclaimer "These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease" is printed adjacent to the claim block per FDA guidance.
What is the dehydration spec for the grass powders?
Wheatgrass and barley grass are cold-processed at temperatures below 95F to preserve enzyme activity (chlorophyllase, superoxide dismutase, peroxidase). The dehydration moisture endpoint is at or below 4% by Karl Fischer titration. Each grass lot is screened for mycotoxin DON at or below 500 ppb by HPLC and aflatoxin B1+B2+G1+G2 by HPLC-fluorescence detector against FDA action levels. The 4% moisture cap is what enables the 24-month room-temperature shelf life without nitrogen flushing.

Technical Specifications: Detox + Greens Stack
The global greens powder category is projected at $1.8 billion by 2028 with 8.2% CAGR, and 4 of the top 5 SERP competitors for 'private label green superfood powder' now disclose 15-ingredient panels above the fold. Our detox-greens stack publishes the same 15-active panel and adds a per-ingredient mechanism and standardization column that no western competitor currently ships. Every batch leaves our 50,000 sq ft Shenzhen production facility (operated under HK-headquartered Smart Sense Group LTD, Wan Chai HK address) with a signed Certificate of Analysis from an ISO 17025 accredited third-party lab. Production runs to 21 CFR Part 111 cGMP, ISO 22000, ISO 9900, HACCP SZX 243490, and the active GMP-Junzhao 2025-26 audit. MOQ is 500 units for pouches, 300 for canisters, 30-40 day production window.
Hero greens block: organic Spirulina platensis 1500mg per 8g serving, protein 60% by Kjeldahl method, chlorophyll 1.2% by spectrophotometry at 660nm, particle size D90 at or below 80 microns. Cracked-cell Chlorella vulgaris 1000mg, mechanical bead-mill cell-wall rupture verified at 85% to 95% breakage rate under 400x microscopy, particle size 8-12 microns (uncracked chlorella runs 2-8 microns; the cracked spec is what drives the cell-content bioavailability claim). Organic wheatgrass juice powder 500mg, cold-processed below 95F to preserve enzyme activity, dehydration moisture endpoint at or below 4% on Karl Fischer titration, lot-tested for Mycotoxin DON at or below 500 ppb. Organic barley grass 500mg, USDA organic certified, pesticide screen non-detect on a 280-compound GC-MS panel against EPA tolerances.
Detox stack with mechanism and standardization: Dandelion root extract (Taraxacum officinale) 250mg at 10:1 standardization, equivalent to 2,500mg dried root, supports occasional bile flow and renal filtration via taraxasterol and inulin fractions. Milk thistle (Silybum marianum) 200mg standardized to at least 80% silymarin flavonolignan complex by HPLC, supports hepatic glutathione pathways. Senna leaf (Cassia angustifolia) 50mg standardized to 6% sennosides A and B (3mg sennosides per serving), supports occasional bowel regularity (FTC-compliant structure-function language; not framed as a laxative claim). Apple pectin 500mg, esterified pectin polysaccharide with documented in-vitro chelation of Pb, Cd, and Hg ions through carboxyl-group binding. Probiotic blend 5 billion CFU at manufacture from 10 strains, microencapsulated for stomach-acid pass-through, with at least 2 billion CFU guaranteed at 24-month shelf life. Digestive enzymes 100mg amylase / protease / lipase blend assayed to USP dextrinizing units, FCC PC and FIP units respectively.
Third-party release testing per batch: heavy metals by ICP-MS to USP <2232> elemental impurities limits (lead at or below 5 ppm, arsenic at or below 1.5 ppm, cadmium at or below 0.5 ppm, mercury at or below 0.5 ppm); pesticide residue by GC-MS and LC-MS/MS across a 280-compound panel against EPA Code of Federal Regulations 40 Part 180 tolerances; microbial contamination by USP <61> and USP <62> compendial method (total aerobic count at or below 10,000 CFU/g, yeast and mould at or below 1,000 CFU/g, E. coli negative, Salmonella negative in 25g, S. aureus negative in 10g); identity by HPTLC fingerprint against pharmacopoeial reference; potency for silymarin, sennosides, and chlorophyll by validated HPLC-DAD methods. Every shipment ships with the signed COA, allergen statement, and certificate of free sale. Stability data is generated under ICH Q1A(R2) at 25C / 60% RH and 40C / 75% RH for shelf-life substantiation.
