💊 Supplements Kai Greene Likely Uses
Even the best vegan diet needs a few strategic supplements. Based on bodybuilder needs and public statements, here’s what Kai likely takes:
| Supplements | Why It Matters |
|---|---|
| Vegan Protein Powder | To hit 150g+ protein/day without overeating |
| Vitamin B12 | Not found in plants; essential for nerve function |
| Vitamin D3 (Vegan) | Supports immunity and testosterone |
| Omega-3 (Algae Oil) | Anti-inflammatory; brain health (DHA/EPA) |
| Creatine Monohydrate | Proven to increase strength, power, and muscle mass — and it’s not animal-based! |
| Zinc & Iron | Prevent deficiency in plant-based diets (non-heme iron absorption is lower) |
📌 Fun Fact: Creatine is one of the most researched supplements in sports science — and it works just as well (if not better) for vegans, who typically have lower baseline creatine stores.
🔬 Science: Can You Build Muscle on a Vegan Diet?
Yes — and here’s why.
✅ Study: Plant-Based Diets Support Muscle Growth
A 2019 study in the Journal of the International Society of Sports Nutrition found that vegan athletes can build muscle and strength just as effectively as omnivores — as long as they:
- Consume enough total protein
- Eat a variety of plant proteins
- Train with progressive overload
📚 Source: JISSN, 2019 – “Plant-Based Diets for Muscular Strength”
✅ The Game Changers Effect
The 2018 documentary The Game Changers showcased elite vegan athletes — including strongmen, UFC fighters, and Olympians — proving that plants can fuel extreme performance.
Kai Greene is part of this movement — a pioneer who predates the trend.
✅ Protein Quality: It’s About Combination
While most plant proteins are “incomplete,” combining foods (e.g., rice + beans, hummus + pita) creates a complete amino acid profile.
And with supplements like pea-rice protein blends, vegans can easily match whey in quality.
