The micronutrient floor Daily Essentials.
Multivitamin, omega-3 triglyceride, D3+K2, magnesium glycinate, B-complex. The five SKUs almost everyone should be on, dosed at the upper end of the published research.
A letter from the formulator
The daily floor isn't sexy and it isn't trendy — it's vitamin D in winter, omega-3 if you don't eat sardines twice a week, magnesium if you don't sleep on a glycine drip.
When I joined Meridian in 2019, the brief was straightforward: build the daily floor. Not a tenth product to layer on top of a stack people already had — the five core SKUs that should sit underneath every other supplement they take. Magnesium glycinate. Omega-3 in triglyceride form. Vitamin D3 with K2. A multivitamin using the active methylated B-forms. A B-complex for the people who don't want the full multi.
The premise was that the daily-floor category is the one most people get wrong, because the cheapest forms of each input are dramatically less bioavailable than the ones with the published clinical data. Magnesium oxide is roughly 4% absorbed; magnesium bisglycinate is the standard the sleep-and-recovery literature is built on. D3 without K2 raises serum calcium and routes some of it to the wrong tissue. Ethyl-ester fish oil is 70% less absorbed than the natural triglyceride form. Folic acid in a multi is metabolized inefficiently by ~40% of the population because of MTHFR gene variants.
Each Daily Essentials product is built around the form, supplier, and dose with the cleanest published clinical evidence. Albion TRAACS magnesium glycinate. IFOS five-star fish oil. MK-7 menaquinone from natto fermentation with a serum half-life ~50x longer than MK-4. Quatrefolic L-methylfolate. KSM-66 ashwagandha. The branded ingredient identity is verified on every batch — not just total content, which any cheap blend can hit.
What I'd recommend for someone starting from zero: D3+K2 plus omega-3 plus magnesium glycinate. That's the floor. Multivitamin if you want a single-pill backstop on the trace minerals. B-complex only if you specifically know you need higher methylated B-doses (MTHFR variant, high stress, plant-based diet). Everything else stacks on top.

How to stack these
The daily essentials sequence.
- 01
Start with the fat-soluble triad.
D3 + K2, Omega-3 Triglyceride, and (if you tolerate them well) a fat-soluble multivitamin. These three are the most underdosed in standard Western diets and the most impactful when corrected. Take all three with the largest fat-containing meal of the day.
- 02
Add magnesium glycinate in the evening.
400mg, 30-60 minutes before bed. Magnesium is a cofactor in over 300 enzymatic reactions, including D3 activation. If you're supplementing high-dose D3, magnesium status matters for the conversion pathway.
- 03
Layer the B-complex only if needed.
If you're on the multivitamin you're already getting the active B-forms. The standalone B-Complex is for people with elevated B-vitamin demand: MTHFR variants, high-stress profiles, vegan/vegetarian diets, athletes during heavy training blocks.
- 04
Greens are a backstop, not a foundation.
The Daily Greens Foundation is for days when whole-vegetable intake is low. It's not a replacement for produce and shouldn't displace the discrete-input supplements above. Use it as a hedge, not a primary.

Mechanism FAQ
What we get asked the most.
Q.01Do I need all five products in the Essentials line?
No. The minimum effective baseline most adults benefit from is D3+K2, omega-3, and magnesium glycinate. The multivitamin and B-complex are layered on top depending on your specific gap profile. The Daily Greens is a hedge for low-vegetable days, not a foundation.
Q.02Can I take all the fat-soluble vitamins at once?
Yes. D3, K2, omega-3, and the multivitamin can be stacked with the same fat-containing meal — they actually absorb better together. Magnesium and B-complex are water-soluble and timing-flexible; we recommend the magnesium in the evening for the sleep-architecture support.
Q.03Why no iron in the multivitamin?
Adult men and postmenopausal women generally have iron stores at or above the target range — supplementing iron in these populations has been associated with elevated ferritin and oxidative stress. Premenopausal women with bloodwork suggesting iron deficiency should add a standalone iron bisglycinate. We didn't want to make that decision for everyone in a default formula.
Q.04How does this stack with food?
Supplements don't replace whole-food nutrition. The Daily Essentials are meant to backstop the inputs that are difficult to get reliably from food (omega-3 if you don't eat fatty fish 2-3x/week, D3 in winter, magnesium if you don't sleep on a diet of legumes and leafy greens). Eat the food first; supplement the gap.
Q.05When should I expect to feel different?
Honest answer: most people don't notice anything subjective from the Daily Essentials in the first month. These are inputs that correct downstream biomarkers (serum 25(OH)D, omega-3 index, RBC magnesium) rather than producing acute sensation. Recheck bloodwork at 12 weeks — that's what matters.
Q.06Can I take these during pregnancy or breastfeeding?
The omega-3 and D3+K2 are commonly recommended during pregnancy with healthcare-provider guidance. The multivitamin is not formulated as a prenatal — it lacks the elevated folate and iron a pregnancy regimen typically requires. Discuss with your OB or midwife.
