Formula
The Renew31 panel declares ten things: 500 Million CFU of Bacillus coagulans on its own line, and nine botanicals sharing one blend of 430 mg. No individual weight is printed inside that blend, so the only quantitative statement the label supports about a botanical is a maximum: the blend total divided by its position in the printed descending order, from 430 mg at the top to 47.8 mg at the bottom. A maximum is never an amount. The sales material names five of the ten, and six are addressed by no federal health agency this desk could open.

Part A
The count is the first thing here that does not match itself. The panel declares ten things: one organism on its own line with an amount in colony-forming units, and nine botanicals under a single blend weighing 430 mg. The ingredient graphic supplied with this stock shows five.
| Position | As printed on the panel | Amount | In the sales material |
|---|---|---|---|
| Own line | Bacillus coagulans | 500 Million CFU | Named |
| 01 | Chicory Root Inulin | at most 430 mg | Named |
| 02 | Babchi Powder | at most 215 mg | Named |
| 03 | Fennel Seed Powder | at most 143.4 mg | Not named |
| 04 | Fenugreek Powder | at most 107.5 mg | Not named |
| 05 | Ginger Root Extract | at most 86 mg | Named |
| 06 | Lemon Balm leaf Extract | at most 71.7 mg | Not named |
| 07 | Lion's Mane Powder | at most 61.5 mg | Named |
| 08 | Slippery Elm Bark Powder | at most 53.8 mg | Not named |
| 09 | Dandelion Leaf Powder | at most 47.8 mg | Not named |
The five the graphic leaves out are fennel seed powder, fenugreek powder, lemon balm leaf extract, slippery elm bark powder and dandelion leaf powder. A graphic is a finite surface, so the count alone is not the finding. The finding is narrower: a reader who arrives from the sales material and then reads the bottle meets five botanicals nobody told them about, two with a published NCCIH safety line.

Renew31, from $49 a bottle. 30 gummies at 1 gummy a day, so a bottle is 30 days.
Part B
Nothing inside the 430 mg carries a figure. That absence decides the shape of this whole site, so it is worth being exact about what it leaves.
21 CFR 101.36(c)(2) requires a proprietary blend to be declared in descending order of predominance by weight. On this panel that rule is the whole of the quantitative information, because nothing inside the 430 mg carries a figure of its own. The ingredient at position n is bounded by the blend total divided by n, and nothing published narrows it.
“shall be declared in descending order of predominance by weight, in a column or linear fashion” 21 CFR 101.36
21 CFR 101.36(c)(3) supplies the other half: “shall be the total weight of all other dietary ingredients contained in the proprietary blend” 21 CFR 101.36 If the list runs heaviest first, position n cannot be heavier than the average of the n at or above it, so its bound is 430 divided by n: 430 mg, 215 mg, 143.4 mg and down to 47.8 mg at position 9. One weight printed inside the blend would have moved all of them.
The sentence that governs this page
Read every figure of that kind as a bound. It is the most an ingredient could weigh if the ones above it were as light as the rule allows, never the amount in the gummy, and the real amount could be far smaller.
The bounds also cannot be added together: each assumes everything above it is as light as the rule allows.
Part C
Three kinds of statement are available about the things on this panel. The chips below record which kind applies. They are not a quality score.
Four of the ten have a published federal sentence. Only one of those four carries a published dose, and that decides how much any page here can say.
at most 430 mg
Inside the blend - a maximum onlyFDA puts inulin-type fructans at “3 to 40 g/day” FDA; the whole blend is 14% of the bottom of that. The finding: “The strength of the evidence supports that inulin-type fructans extracted from chicory root or extracted inulin-type fructans from all sources, as well as synthetic inulin-type fructans, have a beneficial physiological effect on bone mineral density and absorption of calcium.” FDA
at most 107.5 mg
Inside the blend - a maximum only“There is not enough high-quality evidence to determine whether fenugreek is useful for diabetes or menstrual cramps.” NCCIH “Potential side effects of fenugreek include diarrhea, nausea, and other digestive tract symptoms.” NCCIH And “Fenugreek is not safe for use during pregnancy in amounts greater than those found in food” NCCIH. No dose published.
Six of the ten things this label declares are addressed by no federal health agency this desk could open. That is not a verdict on them. It is the state of what could be read. Each was checked against the complete NCCIH Herbs at a Glance index, the complete NIH ODS botanical list and FDA’s Dietary Supplement Ingredient Directory, rather than searched for once and missed.
This site never cites PubMed or PMC as a federal finding. The National Library of Medicine runs the index; the papers in it are third-party work. Where an agency has published nothing, this site says it has published nothing.
Part D
Of the five things the sales material names, two sit in the bottom half of the blend by weight. That needs no opinion at all.
Bounded at 86 mg. On the graphic, and one of the three botanicals with an NCCIH finding.
Bounded at 61.5 mg. On the graphic, and addressed by no federal source this desk opened.
Not that either is absent. That the label placed both below the midpoint of a 430 mg blend.
The three heaviest positions are chicory root inulin, babchi powder and fennel seed powder, bounded at 430 mg, 215 mg and 143.4 mg. Babchi and fennel have no federal source at all, and fennel is not on the graphic. That is not a defect in the label, which printed the order.
Below the blend the panel prints ten more substances, none with a weight: Glucose Syrup, Water, Sucrose, Natural Flavors, Apple Pectin, Critic Acid, Trisodium Citrate, Black Carrot Extract (Color), Vegetable oil, Carnauba Wax. One is misprinted and reproduced as printed, because a transcription that tidies the label stops being one: Critic Acid is citric acid. Inside the blend the panel writes Lemon Balm leaf Extract with a lower-case leaf. Then No Allergens: An affirmative no-allergens statement is the manufacturer’s own assertion. It is not a declaration format FDA prescribes.
Questions
Every source above was opened and read on October 11, 2026. None of them tested Renew31 itself. They describe single ingredients and the categories they sit in and the labelling regulations that govern this panel, which is a different thing from testing this finished formula.
