If you've been on the MYKO Library for a while, the framing is familiar: pathways have many inputs. Mushroom extracts are one. Cofactors — minerals, vitamins, supporting compounds — are another. The foundational practices (sleep, water, food, breath) are the rest.
A capsule on its own does some work. A capsule plus the cofactors the pathway uses does meaningfully more. This is the practical guide to building that around the MYKO line.
The principle
Each MYKO formula is designed to support a specific biological pathway. Cognition. Foundation. Body. Stress. Mood and presence. Each pathway in the body uses inputs the formula can't fully include without becoming a multivitamin.
The companion stack fills in those inputs. The formulas don't need to do everything. They need to do their thing well, while the rest of the stack does the rest.
This is also why MYKO formulas are sized the way they are. The mushrooms and primary actives are dosed in functional ranges. Cofactors that benefit from higher supplemental doses (like magnesium glycinate at 200–400 mg) are designed to be added separately rather than crammed into the formula.
Magnesium — the universal companion
If you only add one thing to a MYKO protocol, add magnesium.
Magnesium is involved in over 300 enzymatic reactions, including ATP function, neuronal signaling, GABA receptor activity (relevant to sleep), and the calming branch of the nervous system. A significant portion of adults run subclinically low.
The form matters. Magnesium glycinate is the most generally useful form — well-absorbed, gentle, low risk of digestive effects, and particularly relevant when sleep or stress support is part of the protocol. Magnesium citrate works for general use. L-threonate is sometimes used in cognitive contexts.
A practical companion-stack dose: 200–400 mg of supplemental magnesium glycinate, taken with the evening meal or 30–60 minutes before bed.
This single addition compounds with every active formula in the MYKO line. Magnesium supports the same cognitive pathways that NEUROGENESIS is built around — supplementary magnesium extends that support. It also supports the calming pathways that CORTEX is designed for. ADAPT works with magnesium underneath it.
B-complex — the cofactor most cognitive protocols are missing
A B-complex vitamin supplement covers a family of cofactors involved in cellular energy production, methylation, neurotransmitter synthesis, and a lot of the upstream biochemistry that pathway-supportive supplements depend on.
Niacin (B3) is one of the most relevant B vitamins to pair alongside the active formulas — particularly NEUROGENESIS — as a companion cofactor. The full B-complex family — B1, B2, B6, B9 (folate), B12, and others — supports cognitive and energetic pathways that the mushroom compounds work alongside.
A practical companion-stack dose: a quality B-complex from a reputable brand, taken in the morning with food. Look for methylated forms (methylfolate, methylcobalamin) if you tolerate them — these are the active forms the body actually uses.
Most useful alongside NEUROGENESIS and ADAPT.
Vitamin D — the slow seasonal companion
Vitamin D isn't a felt-experience supplement. It's a structural one. Involved in immune function, mood regulation, bone health, and a long list of downstream pathways. Most adults living above latitude 35° run low for parts of the year.
A practical companion-stack dose: 1,000–2,000 IU daily for most adults during low-sun seasons, ideally with a fat-containing meal for absorption. Higher doses warrant testing.
Most useful alongside EMBODY and during seasonal transitions.
Omega-3s — the foundational fatty acids
EPA and DHA — the omega-3 fatty acids from fish or algae — are involved in neural membrane integrity, inflammation regulation, and cardiovascular support. They're not "mushroom adjacent" exactly, but they form part of the same kind of structural foundation that the pathway-supportive compounds work alongside.
A practical companion-stack dose: 1,000–2,000 mg of combined EPA/DHA daily, from a quality source (algae-based works fine for vegetarians).
Most useful as a long-term baseline companion to the MYKO system.
What about adaptogenic plants?
A few classical adaptogens — ashwagandha, rhodiola, holy basil — work well alongside MYKO formulas and serve adjacent pathways. They're not necessary for the system to function, but they can be useful additions for specific goals.
A practical principle: don't stack three new adaptogens at once. If you want to add one, pick the one matched to your dominant pathway, take it daily for 60 days alongside the MYKO formula it complements, and evaluate before adding another.
A practical layered stack
Here's what a complete companion stack looks like, with MYKO at the center:
Daily, year-round: ADAPT (foundation, morning); Magnesium glycinate (200–400 mg, evening); B-complex (morning, with food); Omega-3 (1,000–2,000 mg combined EPA/DHA); Vitamin D (seasonal, 1,000–2,000 IU).
Plus one or two actives matched to current pathways: NEUROGENESIS during cognitive-demand seasons; CORTEX during high-stress weeks or quarters; EMBODY during recovery phases or for body-led practitioners; EUPHORIA during reflective or creative seasons.
Plus the practices that hold the whole thing up: Sleep (7+ hours, consistent schedule); Hydration (water through the day); Movement (anything; consistency matters more than intensity); Breath (a few minutes daily); Time off screens (especially in the hour before bed).
This is a complete protocol. It's also more than most people need to start with.
Where to begin
If you're starting fresh, don't build the whole stack at once. The order I recommend:
1. Sleep, water, and movement first. The foundation.
2. ADAPT daily, for 30 days, to establish the baseline.
3. Add magnesium glycinate in the evening, week three or four.
4. Add the active formula matched to your current dominant pathway.
5. Layer in B-complex, vitamin D, omega-3 over weeks two and three of the new active.
Each addition gets 7–14 days before the next variable comes in. This is how you build a protocol that doesn't quietly collapse by month three.
The system rewards layered, intentional construction. It punishes everything-at-once enthusiasm.
