About monthlees
The supplement industry is built on inflated pricing, confusing labels, and aggressive marketing.
Monthlees exists to fix that.
We believe:
- Supplements should be clinically dosed
- Pricing should be transparent
- Testing should be independent
- And customers shouldn't pay for influencer commissions or retail margins
Instead of hiding costs inside the product price, we use a simple membership model — so you pay what supplements actually cost to make.

Neurotransmitter support
Alpha-GPC and B vitamins support acetylcholine production — a neurotransmitter central to attention, memory, and cognitive processing speed.*
-
Cerebral circulation
L-arginine supports nitric oxide pathways involved in vascular tone — helping promote healthy blood flow, including to the brain.*
-
Smooth, sustained focus
200 mg natural caffeine from green tea paired with 100 mg L-theanine — alertness with balanced stimulation and reduced jitter perception.*
-
Disclosed nootropic stack
Every active dose on the label — 300 mg Alpha-GPC, 600 mg inositol, 50 mg ginseng, 5 mg black pepper extract — not a mystery proprietary blend.*
How it works

Two scoops (7.5 g) in water — Alpha-GPC, L-arginine, inositol, and 200 mg natural caffeine from green tea as listed on the supplement facts panel.
-
Step 2: Focus
Alpha-GPC supports acetylcholine production for attention and cognitive processing; L-theanine helps modulate caffeine for smoother, balanced alertness.*
-
Step 3: Flow
L-arginine supports nitric oxide pathways for cerebral circulation; B vitamins contribute to neurotransmitter synthesis and cellular energy metabolism.*

Evidence-based ingredients
The science behind the ingredients
FocusFuel™ (Sour Gummies) discloses Alpha-GPC, L-arginine, inositol, and a caffeine-theanine stack — not a mystery focus powder. Explore the research below on cognition, alertness, and cerebral circulation.*

L-theanine and caffeine on cognition and mood
Human trials report that L-theanine combined with caffeine improves attention switching and reduces subjective jitter compared with caffeine alone — the mechanistic basis for paired stacking.
L-arginine and nitric oxide pathways
Reviews describe L-arginine as a precursor to nitric oxide — supporting vascular tone and blood flow positioning in cognitive circulation formulas.
Inositol and neurotransmitter signaling
Nutrition reviews discuss inositol's role in phospholipid signaling and neurotransmitter pathways — complementary to cholinergic nootropic stacks.

How much caffeine is in FocusFuel (Sour Gummies)?
Each serving (2 scoops / 7.5 g) contains 200 mg natural caffeine from green tea, plus 100 mg L-theanine. Do not combine with other significant caffeine sources. One container provides 20 servings at the suggested use on the label.
How is Sour Gummies different from other FocusFuel flavors?
Same nootropic actives and doses — Alpha-GPC, L-arginine, inositol, caffeine, L-theanine, and B vitamins. Sour Gummies and Sour Grape both use a 7.5 g scoop; Sour Candy uses an 8 g scoop. Flavor and other ingredients differ — Sour Gummies includes malic acid and blue spirulina for color. Compare supplement facts on each product page.
How is FocusFuel different from Downshift Calming Gummies?
They are separate SKUs for different goals. FocusFuel (Sour Gummies) is a caffeinated nootropic drink mix with Alpha-GPC, L-arginine, and 200 mg green tea caffeine for alert focus. Downshift is a non-stimulant evening calm gummy with L-theanine and botanicals — compare labels on each product page.
Why I created monthlees...
When I was 19 years old, I was diagnosed with a brain tumor. That experience forced me to start asking deeper questions about how the human body actually works.
Over the next 18 months, I immersed myself in studying health, nutrition, and neuroscience — eventually earning my degree in Neuroscience from Duke University. Along the way, I discovered something powerful: the body is incredibly resilient & inherently self-healing when it’s given the right support.
Strategic nutrition and supplementation became a major part of my own health journey. And over the last two decades, I’ve devoted my life to helping millions of people around the world take a more proactive role in their health.
That experience completely changed how I thought about health — and ultimately shaped the way Monthlees was built.
I created Monthlees because I was tired of seeing people pay premium prices for supplements that were under-dosed, over-marketed, and difficult to trust.
My goal is simple: build the kind of brand I would want for myself and my family — with better ingredients, transparent formulas, meaningful dosages, and a business model built on long-term trust.
— Chris Walker, Founder of Monthlees
