Open up a byMae label and you'll see a long, plainly listed cast of vitamins and minerals — 22 for adults, 17 for littles — no proprietary blends. A handful of those nutrients pull a specific kind of weight: they're the everyday immune-support nutrients.
These aren't a 'boost.' They're the steady, foundational inputs that help support the normal function of your immune system, chosen for how well your body can actually absorb them and how well they work together. Here's a plain-language tour of the headliners — vitamin D, vitamin C, zinc, and selenium — and what each one actually does.
What 'immune-support nutrient' actually means
It's a structure-and-function idea. Certain vitamins and minerals are building blocks your immune cells need to grow, function, and stay protected as they do their job. Run low on them and the system has less to work with; supply them daily and you're keeping the foundation stocked.
byMae folds these in alongside beta-glucan, a natural fiber from baker's yeast.
Zinc — the builder (15 mg)
If the immune system is a team, zinc helps build the roster. It supports the basic growth and function of immune cells — from fast-acting first responders like macrophages to the adaptive specialists like T-cells and B-cells. Without enough of it, you can't really field a full team.
The adult formulas have 15 mg of zinc, 136% of the Daily Value: a bisglycinate chelate in the Drink and a zinc amino acid chelate in the Capsules. multi+ for littles has 1.8 mg of zinc, as zinc citrate, in two chewables.
Selenium — the bodyguard
An immune response is, by nature, a little messy — it generates oxidative stress as a byproduct. Selenium is an essential trace mineral that acts as an antioxidant, helping protect cells from oxidative stress. It supports normal immune function and normal thyroid function.
The adult formulas have 70 mcg of selenium as L-selenomethionine; multi+ for littles has 12 mcg in two chewables.
Vitamin D — and why it never travels alone
Vitamin D is one of the everyday immune-support nutrients, and byMae supplies it as D3 (cholecalciferol — the form your skin makes from sunlight) at 1,500 IU, or 37.5 mcg, per adult serving. It's a fat-soluble vitamin, which means the body stores the extra, so the dose is set to be effective without overshooting.
Crucially, byMae pairs D3 with 90 mcg of vitamin K2 as MK-7. D3 supports calcium absorption for healthy bones, and K2 helps direct that calcium where it belongs — a classic example of nutrient pairing, where two nutrients are formulated together because they do their best work as a team.
Vitamin C and the art of nutrient pairing
Vitamin C rounds out the everyday immune-support group. It's water-soluble, so your body uses what it needs and flushes the rest — which is part of why a daily, consistent intake matters more than an occasional megadose.
It's also a quiet team player: vitamin C makes plant-based iron far more bioavailable, helping the 13.5 mg of iron (as ferrous bisglycinate chelate) in the adult formulas get absorbed. multi+ for littles has no iron. That kind of matchmaking — pairing nutrients that help each other shine — is how byMae formulates the whole label.
The form matters as much as the number
A big dose on a label means little if your body can't use it. So byMae picks the most absorbable form of each nutrient rather than the cheapest: bioactive 5-MTHF folate and methylcobalamin B12 (ready-to-use, no conversion required), plus chelated minerals like zinc bisglycinate chelate and magnesium bisglycinate that are gentle on the stomach.
Each dose is set to be effective while staying within safe limits — comfortably above the Daily Value where it helps, well below the Upper Limit where that matters, especially for the fat-soluble vitamins your body stores. It all arrives in one daily serving — nutrients and beta-glucan together — so a single routine can replace a shelf of single-purpose bottles. As always, check with your healthcare provider before starting or changing a supplement routine.
