Desiccated Liver Powdered form of dried liver, often used in shakes. High in iron, B vitamins, and protein for maximum recovery. Mix with water or add to homemade shakes for nutrient-packed drinks. Handle carefully due to cross-contamination risks in manufacturing.
Vitamin B12 A key vitamin for red blood cell production and energy metabolism. Improves endurance and muscle oxygenation during intense training. Take in supplement form or as part of a multivitamin. Excessive doses may cause side effects like headaches or dizziness.
Multivitamins Comprehensive supplements covering essential vitamins and minerals. Fills nutritional gaps, supports immunity, and enhances recovery. Take daily with meals for better absorption. Choose reputable brands to avoid poor-quality formulations.
Iron Supplements Provides dietary iron to enhance oxygen transport in the blood. Reduces fatigue and improves performance during high-intensity training. Take as directed by a doctor or based on dietary needs. Overdosing can lead to iron toxicity—consult a GP if unsure.

Brewer’s Yeast Tablets Compressed yeast tablets packed with B vitamins and minerals. Boosts energy and protein metabolism; supports overall recovery. Take with meals or add to shakes as a convenient supplement. Start small to gauge tolerance, as large doses may cause gastrointestinal issues.

Protein Powders: The Foundation of Every Classic Physique

Protein is non-negotiable if you want to build muscle. In the 70s, protein powders weren’t the highly-processed, flavor-loaded shakes we have today. They were simple, effective, and often gritty.

  1. Egg Protein
    • Made from egg whites.
    • High-quality protein source (packed with all essential amino acids).
    • Bodybuilders loved it because it was lactose-free, making it ideal for anyone with milk allergies.
  2. Milk Protein
    • Often made from casein or whey.
    • Digests slower than egg protein, making it great for overnight recovery.
    • Rich in essential amino acids for muscle repair.

Pro Tip: If you’re already hitting your daily protein intake, adding these powders might not make a noticeable difference. But if your diet’s lacking, they’re a game-changer.

Liver Tablets: A Forgotten Secret Weapon

Liver tablets were a staple for bodybuilders looking to pack on lean mass. They’re not sexy, but they’re packed with iron, vitamin B12, and amino acids.

  • What are they?
    Small, compressed tablets made from desiccated (dried) liver.
  • Why use them?
    They boost red blood cell production, increasing oxygen delivery to muscles. This means better pumps, improved recovery, and enhanced endurance.

Warning: Check the label if you’re allergic to any ingredients. There’s always the risk of cross-contamination during manufacturing.

Brewer’s Yeast: Nature’s Multivitamin

Brewer’s yeast tablets were another classic staple. Rich in B-complex vitamins, chromium, and selenium, these little powerhouses gave bodybuilders the energy they needed for intense training.

  • Best for: Supporting metabolism and recovery.
  • How to take: Usually in tablet form, sometimes mixed into shakes for added nutrition.

Desiccated Liver: Hardcore Nutrition in Powder Form

Desiccated liver was like liver tablets but ground into a powder. It was often mixed with water or blended into raw liver shakes (yeah, they weren’t messing around).

  • Nutritional profile: Packed with iron, protein, and fat-soluble vitamins like A and D.
  • Why use it? For maximum recovery and muscle-building potential.

Vitamin Supplements: The Micronutrient Advantage

Old-school bodybuilders didn’t just focus on macros—they knew micronutrients were just as important.

  1. Vitamin B12
    • Boosts red blood cell production.
    • Supports energy levels and endurance during grueling workouts.
  2. Multivitamins
    • Provided a safety net to cover any dietary gaps.
    • Focused on key nutrients like vitamin C, zinc, and magnesium for immunity and recovery.
  3. Iron Supplements
    • Essential for oxygen delivery to muscles.
    • Helped combat fatigue from intense training.

Homemade Blends: Old-School DIY Nutrition

Back then, bodybuilders weren’t afraid to get their hands dirty. They made homemade blends packed with nutrients.

  1. Blended Liver and Organ Meats
    • Why? Organ meats are some of the most nutrient-dense foods on the planet.
    • How? Blend cooked liver with water, garlic, and a touch of lemon juice.
  2. Raw Liver Shakes
    • The ultimate hardcore supplement.
    • Warning: Eating raw liver carries obvious risks like allergens and potential cross-contamination. Proceed cautiously.

Health Food Store Supplements: Affordable Alternatives

In the 70s, big-brand supplements weren’t everywhere. Bodybuilders often turned to health food stores for natural, no-frills solutions.

  1. Brewer’s Yeast Tablets
    • Rich in vitamins and minerals.
    • Boosts energy and supports protein metabolism.
  2. Fish Powder
    • A niche supplement loaded with omega-3 fatty acids for joint health.
    • Often added to homemade shakes for extra protein and healthy fats.
