Moat + Keel — the two daily drivers, immune + digestive
Discount applies at checkout. No code needed.
Daily supplements for immunity, digestion and everyday energy. Made in the USA, with every milligram printed on the label.
The NHS asks everyone in the UK to consider a vitamin D supplement from October to March, because there is not enough sun to make your own. By the end of winter about one in six adults is properly deficient. Most of us still do nothing about it.
Every dot is one adult. The dark ones are below the level the UK counts as deficient. The pale ones are still being told to top up. Moat is nine of those top-ups on one label, so it is one thing to remember instead of nine.
Source: NHS vitamin D guidance and the National Diet and Nutrition Survey.
All nine, printed per two-capsule serving.
Small on purpose. A handful of formulas we are properly fond of, rather than a whole shelf of them.
Every dose in the bottle, drawn against the biggest one. The few with no official Daily Value are marked as such, which is paperwork rather than mystery.
A tiny checklist that decides whether an idea ever gets its own bottle.
Every milligram sits right next to its ingredient, in plain readable numbers. No squinting, no maths.
We read the papers behind every ingredient and write them up in words a person can hold onto before coffee.
Blended in FDA-registered, GMP-certified facilities, then packed and posted from a small corner of Colorado.

Every dose sits on the product page before you buy, milligrams and all, so you can read the whole thing with a cup of tea first.
Tap any ingredient for its milligrams, its %DV and the study behind it. No pop-ups, promise.

Replaced 4 separate bottles on my counter!
I used to take separate vitamin C, D3, zinc picolinate, and elderberry gummies every single morning. MOAT consolidates everything into two daily capsules with zero hassle. My supplement drawer is finally decluttered, and the ingredient balance is spot on.
P-5-P active B6 and Zinc Citrate show serious formulation thought
As someone who checks supplement labels rigorously, I was thrilled to see pyridoxal 5'-phosphate (P-5-P) for B6 and zinc citrate instead of cheap pyridoxine HCl and zinc oxide. The 500mg elderberry extract combined with bioflavonoids provides genuine synergy.
Essential companion for frequent business travel
I fly domestically twice a week and spend countless hours in airports and crowded train carriages. Keeping MOAT in my carry-on has become my non-negotiable routine. Two capsules with breakfast water and I feel well-defended against travel fatigue.
A kindergarten teacher's daily armor
Working in a classroom with thirty 5-year-olds means you are exposed to every cough and sneeze imaginable. I've taken MOAT consistently for three months throughout the fall semester and have maintained my energy and wellness straight through. Highly recommend.
Zero herbal burps or synthetic aftertaste
Many botanical blends give me unpleasant herbal repeating or acid reflux but MOAT goes down smooth with zero aftertaste. The capsules are easy to swallow with a standard glass of water.
Clean formulation without synthetic excipients
Love that Knurle uses brown rice flour instead of magnesium stearate, artificial colorings, or titanium dioxide. It feels like a clean, pure product manufactured to high standards in the USA.
Elderberry benefits without 15g of gummy sugar
I wanted the immune benefits of Sambucus nigra elderberry, but couldn't stand the sugar and syrups in commercial elderberry gummies. MOAT delivers a full 500mg extract in pure capsule form without adding empty calories.
Consistent defense for night shift healthcare workers
Working 12-hour rotating night shifts in the hospital wrecks your circadian rhythm and immune reserves. Taking MOAT with my first meal of the shift keeps my daily nutrient base covered effortlessly.
Great addition of L-Lysine and citrus bioflavonoids
Most immune blends only include Vitamin C and Zinc. The addition of 100mg L-Lysine and citrus bioflavonoids makes a real difference when managing daily stress and cellular defense. Thoughtful formulation.
Smooth capsules, no horse pills here
I normally struggle with swallowing large multivitamin tablets but these two standard-sized gelatin capsules go down very easily with water. No dry throat or sticking.
Household staple for the entire winter season
Both my husband and I take two capsules every morning alongside our breakfast. We used to catch whatever was going around the office but staying consistent with MOAT has kept us feeling resilient all season.
Keeps me healthy through grueling marathon training blocks
When running 60+ miles a week your body is under heavy physical stress and your immune system can dip. Adding MOAT to my morning recovery stack has kept me consistent and training without unexpected interruptions.
A short list, mostly so you do not have to go hunting for it on the back of the bottle.
Every milligram gets its own line on the label.
The elderberry is a 500 mg extract, tucked into a capsule.
Nine things, each with a job to do.
If there is no paper, it does not go on the bottle.
