Every dose on our label came from a decision we can explain, and this article walks through five of them. The short version of our philosophy: doses you can verify beat doses that impress.
Supplement labels are usually presented as settled fact — as if 6,000 mcg of this and 2.7 mg of that arrived by natural law. They did not. Someone chose every number, and the choices reveal what a brand is optimizing for. Here is what we optimized for, decision by decision.
The principle first
A dose can be chosen to look good on a banner, or chosen so that a careful customer can check it against public reference values — Daily Values, tolerable upper intake levels, the ranges typical products actually use — and find it defensible. Those two goals produce different labels. A banner-first label maxes out the cheap, dramatic-sounding ingredients and hides the rest in a blend. A verify-first label puts a real number next to every ingredient and accepts that some of those numbers will look modest.
We built a verify-first label. Fifteen actives, every amount disclosed, no proprietary blends — we wrote about why blends are a red flag separately. Below are five doses from that label and the reasoning behind each.
Five decisions, explained
1. Biotin: 6,000 mcg — above typical, below stunt territory
Yes, 20,000% DV is a startling figure — until you know the Daily Value for biotin is only 30 mcg, so percentages inflate fast. Hair-focused supplements commonly run 2,500 to 10,000 mcg, and biotin is water-soluble, with excess excreted rather than stored. We set 6,000 mcg deliberately inside that typical range: a full serving of the headline ingredient, without chasing the escalating numbers some products use purely for shelf appeal. Bigger was available to us; it just was not better. One genuine caveat scales with any biotin dose — it can interfere with certain blood tests — and we say so plainly in our biotin side effects guide rather than in fine print.
2. Vitamin D: 10 mcg — 50% DV, on purpose
Vitamin D plays a role in normal hair follicle cycling, and low status is common enough that it was worth including.* But D is fat-soluble — it accumulates — and it is the vitamin people are most likely to already be getting elsewhere: sunshine, fortified milk, a standalone D supplement their doctor recommended. So we sized it as a gap-filler: 10 mcg (400 IU), exactly half the Daily Value. Enough to meaningfully top up an ordinary day, small enough to stack politely with whatever else your routine already includes.
3. Zinc: 2.7 mg — kept small because excess is a real thing
Zinc contributes to normal hair tissue growth and skin health, so it belongs in the formula.* But zinc is also everywhere — multivitamins, fortified cereals, cold lozenges — and chronic excess has a documented cost: too much zinc over time interferes with copper absorption, and the adult tolerable upper limit is 40 mg per day. A daily-habit product should not sprint toward that ceiling. We kept zinc at 2.7 mg — 25% DV — precisely because we expect our gummies to be taken every day, alongside food and possibly other products. A brand that maxed every mineral would look more impressive on paper and be worse for the person actually swallowing it daily.
4. Vitamin B12: 8 mcg — 333% DV, and here is why that is not hype
After the zinc logic, 333% DV looks inconsistent. It is not, for two reasons. First, the Daily Value for B12 is tiny — 2.4 mcg — so 8 mcg is a small absolute amount dressed in a large percentage. Second, B12 absorption is genuinely inefficient: uptake depends on intrinsic factor, a stomach protein that saturates quickly, so only a fraction of any single oral dose is absorbed. B12 is water-soluble, and supplementing above 100% DV is standard, boring practice for exactly this reason. The percentage looks like marketing; the absorption math is the actual explanation.
5. Collagen: 12 mg — honestly small
Dedicated collagen powders deliver 2,500 to 10,000 mg. Our marine collagen (from tilapia — note the fish allergen) is 12 mg: a supporting ingredient, not a collagen supplement, and we say so in plain words in our marine collagen explainer. We could have listed it inside a blend and let the word do the work. Instead the small number sits on the label where you can see it — because a brand that will admit its smallest dose has earned more trust on its largest one.
How to audit any label — including ours
The same three checks work on every supplement facts panel. Is every active listed with an amount, or do blends hide the math? Do the percentages make sense against the size of the Daily Value, or is a tiny DV being used to manufacture a huge number? And do the doses respect upper limits for the nutrients that have them, or is everything maxed for effect? Run our label through those checks — every dose is published on our ingredients page. We chose numbers we were comfortable defending in an article like this one, because a dose you can verify beats a dose that impresses, every time.
