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

Most women I work with aren’t doing anything wrong. They’re eating well, exercising, taking their supplements faithfully. They’re just still tired, foggy, and not quite themselves – and they can’t figure out why.

After years as a certified nutritionist, I’ve come to the same conclusion again and again: the supplements aren’t working. Not because the women aren’t consistent, but because most women’s formulas are missing the foundational nutrients that actually move the needle.

So I went looking for something better. I spent the last several weeks testing three of the most popular options on the market — Primal Queen, Olly, and Gruns — and I’ll tell you upfront: one of them genuinely surprised me. It’s now the only brand I recommend to my clients.

Here’s exactly what I found.

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

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

I’ll be direct: if you’re here because you’re exhausted, foggy, and frustrated that nothing is working — this is the section that matters.

Olly was the easiest to rule out — the gummies tasted great, but the crashes, foggy mornings, and mood swings didn’t budge. It felt designed to be enjoyable, not effective. Gruns got closer, with small energy improvements around week two, but nothing that compounded or built over time. Both felt like they were papering over symptoms rather than fixing anything foundational.

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.

👑 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.
