Heart & Soil has become a major name in animal-based nutrition, especially among functional fitness and hybrid athletes. The brand focuses on whole-food organ supplements, joint-support blends, and grass-fed whey protein — all positioned as a natural alternative to synthetic multis and mass-market formulas.
They’ve also built real credibility inside the competitive fitness space. Four-time CrossFit Games Masters Champion Jason Grubb and seven-time Games athlete Bethany Flores both use Heart & Soil products daily, calling out improvements in energy, recovery, and resilience during high-volume training periods.
To get a clearer picture, we tested several products and gathered feedback from athletes using them in everyday training — including Rusty, a fitness coach in Los Angeles, who has been taking multiple Heart & Soil products consistently for BOXROX and recently ran the Chicago marathon.
Below are the results.
What We TestedFirst ImpressionsConvenience
Most athletes aren’t cooking organ meats weekly, so the capsules are an easy way to get the nutrients without dealing with prep or taste.
As Rusty put it:
“The taste takes some getting used to… but having it in condensed pill form is perfect.”
Dosing
Heart & Soil recommends starting with one capsule per day and gradually increasing. Most users report meaningful effects after a few weeks of consistent use.
Athlete Endorsements
Jason Grubb
Uses Pure American Liver daily to support energy and recovery between training blocks.
Bethany Flores
Regularly takes Mood, Memory & Brain for focus during high-stress phases of Games prep.
When athletes at this level take a supplement voluntarily — and repeatedly — it’s usually a sign that the product does something useful.
Performance Review1. Recovery & Muscle Soreness
This is where Heart & Soil performed strongest.
Rusty told us:
“I typically take it at night and it seems to help me reduce muscle soreness. I notice I’m more sore when I don’t take it.”
Organ blends deliver high amounts of B12, vitamin A, choline, heme iron, and CoQ10 — all nutrients involved in tissue repair and cellular recovery. Our athlete feedback aligned with this: consistent use led to noticeably reduced soreness.
2. Joint Health
Joint Strength & Repair includes traditional cartilage and connective-tissue ingredients. While modern research is limited, athletes training with high volume and repetition tend to report fewer flare-ups and better long-term joint comfort.
3. Energy & Vitality
Liver is historically known for supporting energy production. Athletes using Heart & Soil’s liver-focused products generally experience steadier energy across the day — not a stimulant spike, but a more reliable baseline.
4. Protein Quality
The Grass-Fed Whey in Chocolate Sea Salt stood out for taste and mixability. Smooth, not overly sweet, and easy to blend with water or milk.
Rusty’s verdict:
“The taste is great… it didn’t need much.”
The ingredient list is clean, and the grass-fed sourcing will appeal to athletes who care about quality.

Worth it for:
High-volume CrossFit, HYROX, and hybrid athletes
Anyone wanting whole-food nutrient support
Athletes who struggle with recovery
People who won’t cook organ meats but want the benefits

Heart & Soil delivers where most functional and hybrid athletes need support: recovery, nutrient density, and reliable day-to-day energy. It’s not the cheapest option, and the capsules won’t appeal to everyone, but the performance impact is clear.
If recovery is your limiting factor — and for most competitive athletes, it is — Heart & Soil is a strong addition to your supplement routine.
