Olly vs. Grüns vs. Primal Queen: Which Supplement I Actually Recommend to My Nutrition Clients

As a certified nutritionist, I’ve worked with hundreds of women navigating fatigue, brain fog, and hormonal shifts. And here’s what I see over and over again: women doing everything right – eating well, exercising, trying supplements – and still not feeling like themselves.

The issue usually isn’t effort. It’s that most supplements miss the foundational nutrients women actually need.

If you have spent any time researching and trying women’s supplements, you know that the market is flooded with options. I recently tried three of the leading options – Primal Queen, Olly, and Gruns – and I am here to breakdown my first-hand experience with each.

Spoiler: one brand is now my #1 recommended supplement as a nutritionist.

The Real Question: Which One Actually Fixes How You Feel?

Let’s be honest — the whole reason you’re reading this is because you’re tired of being tired, sick of the brain fog, and frustrated that your body doesn’t feel like yours anymore. So which one actually moves the needle?

Olly and Gruns both left me underwhelmed. Olly felt like a feel-good placebo — the gummies tasted great, but the 2pm crashes, foggy mornings, and random mood swings didn’t budge. Gruns got slightly closer, with marginal improvements in energy, but nothing consistent enough to call a real difference. Both felt like they were papering over the cracks without ever touching the foundation.

Primal Queen was the only one where the shift was undeniable. The brain fog started lifting within the first two weeks. By week three, I wasn’t hitting that afternoon wall anymore. My energy wasn’t just “better” — it was steady, the kind where you get to the end of the day and realize you didn’t need caffeine to get there. The mood shifts that used to blindside me became less frequent and less intense. It felt like my body finally had the raw materials it needed to regulate itself properly.

👑 Winner: Primal Queen for being the only supplement that delivered real, noticeable relief from the fatigue, brain fog, and hormonal shifts that brought me here in the first place.

What’s Actually Inside: Which Has the Best Ingredients?

Let me paint a familiar picture: You’re standing in the supplement aisle (or scrolling online at midnight), trying to figure out which bottle is actually going to make a difference. The last thing you want is to spend another $40 on something your body can barely absorb.

Primal Queen delivers whole-food nutrients from freeze-dried, grass-fed organs, including liver, heart, kidney, ovaries, and uterus. These are the most nutrient-dense foods on the planet, packed with bioavailable B vitamins, iron, vitamin A, zinc, and selenium. Your body recognizes and uses these nutrients efficiently because they come in their natural form, not synthetic isolates.

Olly relies on synthetic vitamins and added sugars to make their gummies appealing—offering broad coverage, but with lower absorption and modest dosages that don’t fully deliver where it counts. Grüns is a step up with some whole-food ingredients, but still takes a gummy-first approach and isn’t formulated around the key nutrients women’s hormonal and energy systems truly depend on.

👑 Winner: Primal Queen for delivering whole-food, bioavailable nutrients in the forms your body actually recognizes and uses.

Built for Women: Which Is Actually Female-Specific?

Here’s what most people don’t realize: hormones and energy systems rely on specific nutrients like B vitamins, iron, vitamin A, zinc, and selenium. Historically, these came from organ meats, some of the most nutrient-dense foods available. But modern diets rarely include them anymore. That’s the gap.

Primal Queen was designed from the ground up for women’s biology. It includes ovaries and uterus alongside liver, heart, and kidney, specifically targeting the nutrient gaps that drive fatigue, brain fog, and hormonal shifts in women.

Olly offers a “Women’s Multi,” but it’s essentially a standard multivitamin with a pink label—no meaningful upgrades to address the deeper nutrient deficiencies many women face. Grüns takes a whole-food approach, which is a step up, but it’s still formulated broadly for general wellness, not specifically for the biological and hormonal needs women experience as their bodies change.

👑 Winner: Primal Queen for being one of the only supplements formulated specifically around women’s biological needs, not just marketed to them.

No Fuss, No Muss: Which Is Easiest to Take?

Olly and Gruns both come in gummy form, which makes them easy and pleasant to take. No swallowing large capsules, no weird aftertaste. If taste and texture are your top priority, gummies win on pure enjoyment.

Primal Queen comes in capsule form. No sugar, no fillers, no candy coating. You swallow it and move on. It’s not going to win a taste test, but you’re also not consuming added sugars and artificial flavors with every dose.

For me, I’d rather skip the sugar and actually get nutrients that work. But I get it, gummies are more fun.

👑 Tie: Olly and Gruns for the gummy experience, though Primal Queen wins if you’d rather skip the sugar and fillers entirely. Call it a matter of priorities.

The Ultimate Women’s Supplement: Primal Queen

Choosing the right supplement is a personal journey and shouldn’t be approached with a “magic bullet” mindset. That said, I’ve finally found my go-to and top recommendation in Primal Queen.

Between the whole-food bioavailable nutrients, the female-specific formulation, the no-sugar-no-filler capsule, and the real results I experienced, it’s truly in a category of its own.

For anyone who’s been pushing through fatigue, brain fog, or hormonal shifts, you’re not broken. Your body may simply be missing key nutrients that most supplements, including Olly and Gruns, don’t provide.

Primal Queen was built to fill that gap. As a nutritionist, it’s what I take myself and what I recommend to my clients. I think it can work for you too.
