Understanding Plant-Based Nutrition
Plant-based diets are incredibly healthy - lower heart disease, diabetes, and cancer risk! But certain nutrients are harder to get from plants. B12 only exists in animal products (vegans MUST supplement), iron from plants is poorly absorbed (need 1.8x more), omega-3 (EPA/DHA) is rare in plants (need algae oil), and zinc absorption is lower from plants. The good news? Strategic supplementation makes plant-based diets complete and optimal! 🌱💊
🎯 Plant-Based Nutrient Gaps
Nutrients Hard to Get from Plants:
✓ Vitamin B12 (ONLY in animal products - vegans MUST supplement)
✓ Iron (plant iron poorly absorbed - need 1.8x more)
✓ Omega-3 EPA/DHA (rare in plants - need algae oil)
✓ Zinc (lower absorption from plants)
✓ Vitamin D (few plant sources)
✓ Iodine (unless using iodized salt)
✓ Calcium (vegans need to plan carefully)
Easy to Get from Plants:
✓ Vitamin C, Folate, Fiber
✓ Antioxidants, Phytonutrients
✓ Magnesium, Potassium
✓ Most vitamins and minerals
💊 Essential Vegan/Vegetarian Supplements
1. Vitamin B12 - THE MOST CRITICAL
How it works: Makes red blood cells, supports nerves and brain
The science: ONLY in animal products - 100% of vegans need it
Dose: 250-500mcg daily OR 2500mcg weekly (methylcobalamin)
Best for: ALL vegans (non-negotiable!), vegetarians (recommended)
2. Iron - The Energy Mineral
How it works: Carries oxygen in blood, prevents anemia
The science: Plant iron (non-heme) is 5-10x less absorbed than meat iron
Dose: 18mg daily (women), 8mg (men) - take with vitamin C
Best for: Vegans, vegetarians (especially women)
3. Omega-3 (Algae Oil) - The Brain Essential
How it works: Builds brain cells, reduces inflammation
The science: ALA (flax, chia) converts poorly to EPA/DHA (need algae oil)
Dose: 250-500mg EPA/DHA daily (from algae oil)
Best for: ALL vegans (brain health critical)
→ Algae oil supplement (vegan omega-3)
4. Zinc - The Immunity & Growth Mineral
How it works: Immune function, wound healing, growth
The science: Plant zinc is less absorbed (phytates block it)
Dose: 15-30mg daily
Best for: Vegans, vegetarians (especially athletes)
5. Vitamin D3 - The Sunshine Vitamin
How it works: Bone health, immunity, mood
The science: Few plant sources (mushrooms only), most people deficient
Dose: 1000-2000 IU daily (vegan D3 from lichen)
Best for: ALL vegans and vegetarians
→ Vitamin D3 2000 IU (check if vegan)
6. Creatine - The Vegan Performance Booster
How it works: Muscle energy, brain energy (only in meat normally)
The science: Vegans have 20-30% lower creatine levels
Dose: 3-5g daily
Best for: Vegan athletes, brain performance
→ Creatine Monohydrate 5g (vegan)

❓ FAQ
Q: Can I get B12 from nutritional yeast or fortified foods?
A: Maybe, but it's unreliable. Supplements are safer and more consistent. B12 deficiency is serious - don't risk it!
Q: Do I need protein powder as a vegan?
A: Not necessarily! You can get enough protein from beans, lentils, tofu, tempeh. But protein powder is convenient (20-30g per shake).
Q: Are plant-based diets healthy?
A: YES! Lower heart disease, diabetes, cancer risk. But you MUST supplement B12, and ideally omega-3, iron, zinc, and D.
