Getting enough protein on a paleo diet is simpler than most people think — if you know which sources to prioritize. As a functional medicine practitioner and licensed pharmacist, I recommend a target of 100g of protein daily to most of my patients — for muscle preservation, hormone production, blood sugar stability, and gut barrier integrity. The paleo diet is actually one of the best frameworks for hitting this target because it naturally emphasizes the highest-quality, most bioavailable protein sources available. This guide covers the best paleo protein sources, a complete sample day hitting 128g, and the absorption factors that determine whether the protein you eat actually gets used.
Why You Might Want to Aim for 100g of Protein
Many people can benefit from increasing their protein intake to around 100g daily, including:
- Those looking to build or maintain muscle mass
- Individuals recovering from illness or injury
- People experiencing frequent fatigue or slow recovery from exercise
- Anyone dealing with blood sugar regulation issues
- Those working on weight management goals
- People over 40 experiencing natural muscle loss
- Individuals with high stress levels or demanding physical jobs
- Athletes and active individuals
The Fundamental Role of Protein in Your Body
Protein isn’t just about building muscle – it’s the fundamental building block of nearly every structure in your body. When you consume protein, your body breaks it down into amino acids, which serve as the essential “building blocks” for:
- Immune system cells (antibodies, T-cells, and other immune components)
- Enzymes that drive vital chemical reactions
- Hormones that regulate everything from mood to metabolism
- Structural proteins like collagen and keratin
- Neurotransmitters that enable brain function
- Transport proteins that move nutrients through your bloodstream
Recent research has revealed even more fascinating roles for protein in the body. For instance, specific amino acids like leucine have been shown to directly signal muscle protein synthesis, while glutamine plays a crucial role in maintaining gut barrier integrity – a key focus in functional medicine.
Optimal Protein Absorption: A Key Factor in Meeting Your Goals
One often-overlooked aspect of protein nutrition is absorption. Several factors can affect how well your body utilizes the protein you consume:
1️⃣ Stomach Acid Levels: Low stomach acid (hypochlorhydria) can significantly impair protein digestion. This can be caused by various factors, including H. pylori infection, which affects up to 50% of the global population. Signs of low stomach acid include:
- Feeling full quickly
- Bloating after meals
- Undigested food in stool
- Fatigue after eating protein-rich meals
- Frequent burping or acid reflux
- History of H. pylori infection or treatment
2️⃣ Digestive Support Options:
- Protein powders can be an excellent option for those with impaired digestion
- Hydrolyzed proteins or protein isolates are often easier to absorb
- Digestive enzymes or betaine HCl supplements may help (under practitioner guidance)
- Bone broth and collagen peptides offer easily digestible protein forms
Best Paleo Protein Sources — Complete Reference List
These are the paleo-friendly protein sources I recommend most in clinical practice, ranked by protein density:
Animal proteins (highest bioavailability):
- Wild game meat (6oz) — 45g protein
- Grass-fed beef (6oz) — 42g protein
- Free-range chicken breast (6oz) — 38g protein
- Wild-caught salmon (6oz) — 34g protein
- Canned sardines (3.75oz tin) — 23g protein
- Pastured eggs (2 large) — 12g protein
- Bone broth (1 cup) — 10g protein
Seafood options:
- Tuna (6oz) — 40g protein
- Shrimp (6oz) — 34g protein

Convenient paleo protein additions:
- Grass-fed beef jerky (4oz) — 28g protein
- Hydrolyzed collagen peptides (2 scoops) — 18g protein
- Hard-boiled eggs (2) — 12g protein
- Smoked salmon (3oz) — 16g protein
Note: Wild-caught fatty fish (salmon, sardines, mackerel) are my top recommendations because they provide complete protein alongside omega-3 fatty acids that reduce the inflammatory burden of high protein intake — particularly important for patients with gut inflammation or autoimmune conditions.
Sample Day: Hitting 100g Protein the Paleo Way
Breakfast:
- 3 pastured eggs (18g)
- 1 cup bone broth (10g)
Mid-morning snack:
- 4 oz grass-fed beef jerky (28g)
Lunch:
- 6 oz wild-caught salmon (34g)
- Mixed greens with olive oil
Dinner:
- 6 oz free-range chicken breast (38g)
- Roasted vegetables
Total: 128g protein
Beyond Just Hitting Numbers: Quality Matters
Protein quality and digestibility are crucial factors in meeting your nutrition goals. While whole food sources are foundational, don’t discount the value of high-quality protein supplements:
High-Quality Protein Powder Options:
- Hydrolyzed collagen peptides
- Egg white protein
- Hemp protein
- Beef Protein
Benefits of Including Protein Powders:
- Easier absorption for compromised digestive systems
- Convenient option for busy schedules
- Can be gentler on the digestive system
- Helpful for meeting increased protein needs during healing
- Useful for post-workout recovery
- Can be incorporated into recipes for variety
Lesser-Known Protein Facts
Here are some fascinating protein insights that are gaining attention in the functional medicine world:
- Protein timing matters: Research suggests that spreading protein intake throughout the day is more effective than consuming it all at once.
- Protein and circadian rhythm: Morning protein consumption may help regulate your body’s internal clock and metabolism.
- Collagen-specific benefits: While not a complete protein, collagen peptides offer unique benefits for skin, joints, and gut health – all pillars of the paleo approach.
Beyond Just Hitting Numbers
Remember, protein quality matters as much as quantity. On a paleo diet, you’re naturally focusing on whole-food sources rich in:
- Essential amino acids
- Beneficial fatty acids (especially in grass-fed and wild-caught options)
- Important minerals like zinc and iron
- B-vitamins and other micronutrients
How Much Protein Do You Actually Need on Paleo?
100g is a useful target for most people — but optimal protein intake is more accurately calculated by body weight and health goals:
General targets I use in practice:
Minimum for most adults: 0.7g per pound of body weight
Optimal for active people: 0.8–1g per pound of body weight
Recovery or muscle building: 1–1.2g per pound of body weight
People over 40: closer to 1g per pound due to reduced muscle protein synthesis efficiency
For a 150-pound person that’s 105–150g daily — which means 100g is actually a minimum rather than a ceiling for most people. Spreading protein across three meals of 30–40g each is more effective than concentrating it in one sitting — your body can only optimally utilize approximately 30–40g per meal for muscle protein synthesis and hormonal function.

FAQs
You've got questions? We have answers!
The highest-quality paleo protein sources are wild game meat, grass-fed beef, free-range chicken, wild-caught salmon and sardines, pastured eggs, and bone broth. Wild-caught fatty fish are particularly valuable because they combine complete protein with anti- inflammatory omega-3 fatty acids. For convenience, grass-fed beef jerky and hydrolyzed collagen peptides are excellent portable additions.
Not with planning. Three moderate servings of animal protein daily — for example eggs at breakfast, salmon at lunch, and chicken at dinner — easily hits 100g without tracking every gram. The sample day in this guide reaches 128g using straightforward whole food sources.
Yes — the paleo diet is actually well-suited for muscle building because it emphasizes complete, highly bioavailable animal proteins alongside anti-inflammatory foods that support recovery. The key is hitting adequate protein targets (0.8–1g per pound of body weight) and distributing intake across three meals rather than front or back loading.
Each kit includes detailed instructions to ensure proper sample collection. However, we cannot be held responsible for errors in sample collection or submission. If your sample is invalid, you may need to purchase a replacement kit. For assistance, feel free to contact us before collecting your sample.
Hydrolyzed collagen peptides, egg white protein, and beef protein isolate are all paleo-compatible protein powder options. These are particularly useful for people with compromised digestion, high protein needs, or busy schedules. Whey, soy, and pea protein are not paleo-compatible.
Protein provides the amino acid precursors for hormone production — thyroid hormones require tyrosine, cortisol and sex hormones require adequate protein for synthesis, and neurotransmitters like serotonin and dopamine are built from tryptophan and tyrosine. Protein also stabilizes blood sugar which reduces cortisol demand throughout the day — one of the most practical ways to support adrenal health through diet.
