At exactly 5:00 AM every morning, Bryan Johnson drinks 20 ounces of green liquid that most people wouldn’t touch with a ten-foot pole. It’s called the Green Giant, and after testing it myself for 21 days, I understand why he calls it “biohacker coffee.”
This isn’t a juice or smoothie. The Green Giant is Bryan’s first protocol of the day, a precisely engineered supplement drink that delivers spermidine, creatine, collagen, and amino acids in liquid form. While his Super Veggie and Nutty Pudding focus on whole foods, the Green Giant is pure biohacking. It costs about $4 per serving and takes 2 minutes to make.
The taste? Think unsweetened matcha mixed with seaweed and a hint of cinnamon. It’s an acquired taste that took me four days to stop grimacing at. The texture is thin but slightly grainy from the chlorella, with a chalky finish from the collagen. But the effects are undeniable: sustained mental clarity without caffeine, improved workout performance, and the kind of morning alertness that usually requires three shots of espresso. Here’s Bryan Johnson’s exact Green Giant recipe, the science behind each ingredient, and why 20 ounces of algae water might be worth adding to your morning routine.
Jump to Recipe ↓What Makes the Green Giant Different
Unlike Bryan’s food-based meals, the Green Giant is essentially a liquid supplement stack. It’s his answer to morning supplementation: instead of swallowing 20+ pills first thing in the morning, he drinks them.
The star ingredient is chlorella, a freshwater algae that contains one of the highest concentrations of spermidine found in food. Spermidine has become a darling of the longevity community after studies showed it can induce autophagy (cellular cleanup) similar to fasting. Bryan’s 2 tablespoons of chlorella provide approximately 13.5mg of spermidine, a therapeutic dose based on current research.
But spermidine is just the beginning. This drink strategically combines compounds that work synergistically: creatine for ATP production, collagen for tissue repair, amino acids for protein synthesis, and cocoa flavanols for vascular health. It’s designed to prime your body for optimal performance from the moment you wake up.
The Science Behind Each Component
Chlorella: The Autophagy Activator
Chlorella isn’t just pond scum. This single-celled green algae is 60% protein by weight and contains all essential amino acids. Beyond its spermidine content, research shows chlorella can bind to heavy metals, supporting detoxification pathways.
The spermidine in chlorella has been shown to extend lifespan in multiple organisms by promoting autophagy, the cellular recycling process that declines with age. Human epidemiological studies link higher spermidine intake with reduced cardiovascular disease and lower all-cause mortality.
Creatine: Not Just for Bodybuilders
Bryan includes 2.5g of creatine monohydrate, but not for muscle building. Emerging research shows creatine supplementation can improve cognitive function, particularly in tasks requiring quick thinking and during sleep deprivation.
Your brain uses 20% of your body’s energy despite being 2% of your weight. Creatine helps regenerate ATP (cellular energy currency) faster, essentially giving your neurons more fuel. Studies show improvements in working memory and processing speed with daily supplementation.
Essential Amino Acids: Morning Protein Without Digestion
The 7.6g of essential amino acids (EAAs) provide the building blocks for protein synthesis without requiring digestion. After an overnight fast, this immediately signals your body to maintain muscle mass rather than break it down for energy.
Unlike whole protein that takes hours to digest, free-form amino acids are absorbed within 15-30 minutes. This makes them ideal for morning consumption when you want nutrients without digestive burden.
Collagen Peptides: Beyond Skin Deep
The 20g of collagen peptides isn’t vanity. Collagen is the most abundant protein in your body, comprising 30% of total protein. While Bryan famously aims to have the skin of an 18-year-old, collagen also supports joint health, gut lining integrity, and bone density.
Studies show collagen supplementation can improve skin elasticity by 28% in 8 weeks and reduce joint pain in athletes. The glycine in collagen also supports sleep quality when taken earlier in the day.
Bryan Johnson’s exact Green Giant formula, consumed daily at 5 AM.
Ingredients (1 serving – 20 oz)
- 20 oz cold filtered water (about 2.5 cups)
- 2 Tbsp chlorella powder (for spermidine)
- 7.6g essential amino acids (EAAs complex)
- 2.5g creatine monohydrate
- 20g collagen peptides
- 500mg cocoa flavanols (or 1-2 tsp pure cocoa)
- 1 tsp Ceylon cinnamon
Preparation Instructions
- Start with cold water: Pour exactly 20 oz of cold filtered water into a large shaker bottle or blender. Cold water helps with palatability and prevents clumping. Bryan uses filtered water to avoid chlorine that could impact the beneficial compounds.
- Add the chlorella first: Measure 2 tablespoons of chlorella powder and add to the water. This will immediately turn everything deep green. Don’t be alarmed by the strong “pond” smell. That’s normal and indicates fresh chlorella. A good shaker bottle helps here.
- Layer in the amino acids: Add your 7.6g of essential amino acids. If using flavored EAAs (many are citrus), this will help mask the chlorella taste slightly. Unflavored works too but makes the drink more challenging.
- Add performance compounds: Measure and add 2.5g creatine monohydrate (about 1/2 teaspoon) and 20g collagen peptides (usually 2 scoops). These should dissolve easily without clumping.
- Finish with flavor enhancers: Add your cocoa flavanols (or 1-2 tsp pure cocoa powder) and 1 tsp Ceylon cinnamon. These not only provide health benefits but also improve the taste marginally.
- Mix thoroughly: If using a shaker bottle, secure the lid and shake vigorously for 30-45 seconds. Chlorella tends to settle, so shake until completely uniform. If using a blender, blend on medium for 10 seconds. Don’t over-blend as this can create foam.
- Drink immediately: Consume within 5 minutes while everything is still in suspension. Drink it relatively quickly rather than sipping. The taste is easier to handle this way. Chase with plain water if needed.
Nutritional and Supplement Profile
This nutrient profile is unlike any conventional breakfast. Zero sugar, minimal carbs, but packed with bioactive compounds that influence cellular function. The protein content rivals a full meal while remaining liquid for rapid absorption.
Troubleshooting Guide: Making Green Giant Actually Work
After helping dozens of people troubleshoot their Green Giant attempts, these are the most common problems and their solutions, ranked from mild fixes to nuclear options.
Problem #1: “It Clumps Into Green Concrete”
Why it happens: Chlorella is hydrophobic initially. Adding it to water without proper mixing creates impenetrable green balls.
Solutions (easiest to most extreme):
- Add chlorella to a small amount of water first (2 oz), shake vigorously, then add remaining water
- Use room temperature water for initial mixing, then add ice
- Invest in a high-quality shaker with wire ball
- Pre-blend chlorella with just the cinnamon and cocoa (dry mix), then add liquids
- Nuclear option: Use an immersion blender directly in your shaker cup
Problem #2: “I Literally Cannot Handle the Taste”
What it actually tastes like: Ocean water mixed with grass, chalk, and a hint of cinnamon. The chlorella dominates with its algae/seaweed flavor. The collagen adds a weird protein powder chalkiness. The amino acids can be bitter if unflavored. The cinnamon and cocoa barely register. It’s not pleasant, let’s be real.
The taste ladder approach (start at 1, work your way up):
- Beginner: Start with 1/2 tablespoon chlorella, build up over 2 weeks
- Flavor mask: Use citrus-flavored EAAs instead of unflavored
- Temperature hack: Ice-cold numbs taste buds. Use 50% ice water
- Chaser method: Have orange juice ready immediately after
- The nose plug: Seriously. No smell = 70% less taste
- Shot strategy: Make it concentrated (8 oz water instead of 20), shoot it fast
- Nuclear option: Switch to chlorella tablets (less effective but better than nothing)
Problem #3: “My Stomach Feels Like a Washing Machine”
Digestive distress solutions:
- Never drink on completely empty stomach – eat 5-10 almonds first
- Start with 1/4 dose for three days, then 1/2 dose for three days, then full dose
- Split into two servings: half at wake, half 30 minutes later
- Check your chlorella source – organic broken cell wall is gentler
- Reduce collagen to 10g initially (some people need adjustment time)
- Take digestive enzymes 15 minutes before
Problem #4: “I Don’t Feel Any Different”
Signs it’s actually working (even if you don’t feel it):
- You’re going to the bathroom more regularly (chlorella effect)
- Your mid-morning energy is more stable (no 10 AM slump)
- Recovery between workout sets is 10-15 seconds faster
- You’re not craving coffee as intensely
- Skin looks slightly more hydrated after 2 weeks (collagen effect)
If you still feel nothing after 2 weeks:
- Check expiration dates – old chlorella loses potency
- Ensure you’re using proper doses (many people under-dose creatine)
- Time it right: 5-6 AM is optimal, 9 AM is too late
- You might be a non-responder to creatine (30% of people are)
Problem #5: “It’s Too Expensive”
Cost-cutting without compromising:
- Buy chlorella in bulk (1-2 lb bags) – saves 40%
- Use unflavored EAAs (half the price of flavored)
- Generic creatine monohydrate (all creatine is the same)
- Subscribe & Save on Amazon for 15% off
- Make EAAs optional (least critical ingredient)
- Buy collagen in 5 lb containers – drops price by 30%
Frequently Asked Questions
Who Should (and Shouldn’t) Try Green Giant
Ideal candidates:
- Biohackers comfortable with unconventional approaches
- People seeking caffeine-free morning energy
- Those already taking multiple morning supplements

The Biohacking Investment Analysis
At $4 per serving ($120/month), Green Giant costs less than a daily Starbucks habit but more than conventional breakfast. However, when you calculate the cost of buying each supplement separately, the convenience factor becomes clear.
Individual daily costs: Chlorella ($1.20) + EAAs ($0.80) + Creatine ($0.15) + Collagen ($1.00) + Cocoa extract ($0.50) = $3.65. You’re essentially paying $0.35 for the convenience of one drink versus 5-6 supplement pills.
More importantly, the cognitive performance benefits are measurable. If Green Giant gives you two extra hours of productive morning work, the ROI is obvious for knowledge workers. After 21 days, I’ve continued drinking it 5 days a week.
