10 Supplements for Plant-Based Eaters Worth Knowing

Last week, Thorne published a piece by registered dietitian Laura Kunces, PhD, RD, CSSD, listing the 10 supplements she most often recommends to clients on plant-based or vegan diets. It is a useful list. We placed it next to what we actually see with our nutrition coaching clients in Tigard and Portland and added APEX context to each one. You can read Laura's original article on Thorne's Take 5 Daily here.

A note up front. If you are looking for a Thorne Promo Code or a Thorne discount before you read the rest of this, here is the answer most people do not know. Thorne does not run public promo codes. They operate a practitioner partner program for clinics, gyms, and healthcare providers. APEX PWR is a Thorne practitioner partner, which means our community in Portland and Tigard can access the entire Thorne catalog at 25 percent off practitioner pricing. You sign up at apexpwr.com/thorne, place orders directly with Thorne under the APEX practitioner account, and the discount applies automatically. That is the actual Thorne Promo Code most people are searching for.

Why Plant-Based Eaters Have Predictable Gaps

Portland and the broader Pacific Northwest is one of the more plant-forward regions in the country. A meaningful share of our nutrition coaching clients in Tigard eat fully plant-based or are heading that direction. The conversations are familiar and the data on the gaps is well-established. Several nutrients are concentrated in animal-sourced foods and harder to obtain in adequate amounts from plants. Vitamin B12 is essentially absent from a strict plant diet without fortification. Iron from plant sources is absorbed at a meaningfully lower rate than iron from animal sources. Creatine is naturally present in muscle tissue and absent from plant foods. Beta-alanine, a precursor to carnosine and the dominant intramuscular pH buffer during high-intensity work, is hard to get in adequate amounts without meat. Even protein, while easy to hit on a vegan diet in calorie terms, often falls short on the specific essential amino acids that drive muscle adaptation.

None of this is an argument against plant-based eating. The cardiovascular, longevity, and gut health data on plant-forward eating is some of the cleanest in nutrition research. The point is that smart plant-based eaters know where the gaps are and use targeted supplementation to fill them. The list below is the practical version.

The 10, With Our Read on Each

01

Iron Bisglycinate

Iron from plant sources is absorbed at 2 to 20 percent, compared to 7 to 35 percent from animal sources. Plant-based eaters routinely need closer to twice the dietary iron of meat eaters to maintain healthy levels. Iron bisglycinate uses a glycine binding to improve absorption and reduce the GI discomfort common with standard iron supplements.

APEX Read Iron deficiency is one of the most common patterns Jennie sees in her female endurance clients on plant-forward diets, and one of the easiest fixes once it is identified. If you are training hard, plant-based, and feeling flat on workouts you should be crushing, get blood work done before guessing. Low ferritin is a fixable problem.

02

Vitamin B12 (Methylcobalamin)

Vitamin B12 is found almost exclusively in animal products. A strict plant-based diet without fortification or supplementation is a B12 deficiency in slow motion. B12 is required for red blood cell production, nervous system function, and energy metabolism. Methylcobalamin is the active form your body uses directly.

APEX Read This is the single supplement we tell every plant-based client they cannot skip. The deficiency builds slowly over months or years, and the early signs (fatigue, brain fog, mild numbness in extremities) are easy to misattribute to overtraining or poor sleep. If you have been plant-based for more than a year and have not had B12 levels checked, get them checked.

03

Methyl-Guard Plus

Healthy methylation supports cardiovascular, cognitive, and bone health, and helps regulate homocysteine. Methyl-Guard Plus combines 5-MTHF (active folate), active B2, B6, and 3 mg of methylcobalamin B12 to support methylation pathways with co-factors that work together.

APEX Read For our clients tracking blood work seriously (elevated homocysteine, MTHFR variants, family history of cardiovascular disease), this is the methylation product we point to. It is not a beginner supplement. If you do not know whether you need it, you probably do not. If your physician has flagged any of the above, this is the relevant tool.

04

Creatine Monohydrate

Creatine is naturally present in muscle tissue and effectively absent from plant foods. Plant-based eaters tend to have measurably lower baseline creatine stores than omnivores, which means they often see larger gains from supplementation. Creatine supports ATP regeneration for muscle work and shows emerging evidence for cognitive function in older adults and under stress.

APEX Read We just published a full Lessons in Longevity piece on creatine for the aging brain and body, where we walked through what the evidence actually supports beyond the muscle benefits. Read the deep version here. The short version: 3 to 5 grams per day, monohydrate, every day. For plant-based eaters, this one moves the needle more than for omnivores because the baseline is lower.

05

Beta Alanine-SR

Beta-alanine is a precursor to carnosine, the primary intramuscular pH buffer during high-intensity work. It is concentrated in animal protein, and plant-based eaters tend to have meaningfully lower baseline carnosine levels. Supplementation supports muscle work capacity and time to exhaustion at high intensities. The sustained-release version reduces the tingling sensation that comes with standard beta-alanine.

APEX Read Most directly relevant for our Hyrox and high-intensity training community. As we covered in this volume's Endurance Extras piece, 70 percent of a Hyrox race is spent at hard or very hard intensity. Carnosine is the system that keeps your muscle pH from collapsing during that kind of work. Plant-based athletes preparing for Hyrox or any 10-to-90 minute high-intensity event should consider this near the top of the stack.

06

Plant Protein

A Vegan Verified blend of pea, brown rice, and chia delivering 22 grams of complete protein per serving with all nine essential amino acids, including BCAAs. This is the practical answer to the most common gap in plant-based eating: hitting daily protein numbers required for muscle preservation and recovery without overshooting calories.

APEX Read In our Nutrition Nook this volume, we broke down Jennie's Core 4 Meals framework built around a 30 to 40 gram protein anchor at every meal. For plant-based clients, that protein anchor is the hardest part of the system to design without it feeling repetitive. A clean plant protein powder makes one meal per day trivial to hit and frees up your other meals to be actual food. Chocolate or vanilla. If you want objective confirmation that the protein is doing its job, a periodic DEXA body composition scan shows your lean mass changes precisely (within about 1 percent) and is the cleanest way to verify the supplementation is preserving muscle.

07

Amino Complex

Essential amino acids in free-form, ready for absorption without digestion. Useful when whole-food protein is hard to get down (post-workout, while managing calories, traveling, or in older adults working to preserve muscle mass). This is one of Thorne's Verified Vegan formulas.

APEX Read Sarcopenia accelerates after 40, and plant-based eaters in midlife and beyond are working uphill on the protein side already. For our Lessons in Longevity audience, Amino Complex is a useful tool around training sessions when you want the EAA dose without the volume of a full protein shake. Not a daily must-have. A useful piece of the toolkit for serious training stretches and travel weeks.

08

EnteroMend

L-glutamine plus complementary plant-sourced ingredients designed to support the gut barrier and immune function. High-stress lifestyles and prolonged high-intensity training elevate systemic inflammation and can compromise gut barrier integrity. EnteroMend's L-glutamine is fermented from glucose, not animal-derived.

APEX Read We see a predictable pattern in Hyrox and high-volume training prep blocks: GI complaints around the third or fourth week of a hard cycle. Some of that is training stress, some is dietary changes, some is fiber adjustments. EnteroMend is one of the tools we point clients to during the toughest training stretches, alongside a closer look at sleep and food quality. Not a forever supplement. A targeted one.

09

Bacillus Coagulans

A spore-forming, soil-derived probiotic that survives stomach acid and reaches the intestines intact. Most probiotic strains are dairy-derived, so this is one of the cleaner Vegan Verified options. Supports general GI function and the kind of microbiome diversity we covered in the Nutrition Nook fiber piece.

APEX Read Worth pairing with the fiber strategy from this volume's Nutrition Nook on the fiber gap. Fiber feeds gut bacteria; probiotics deliver bacteria. Both work better together than either does alone. For plant-based eaters who already eat a fiber-rich diet, this is often a "round it out" rather than a "start here" supplement. For those just transitioning to plant-forward eating and dealing with GI adjustment, it can help that first month or two.

PharmaGABA

A natural form of GABA produced via fermentation by Lactobacillus hilgardii (the same strain used in kimchi). Clinical research shows it reduces stress-related beta brain wave activity and increases alpha wave activity, supporting relaxation while preserving mental focus. Useful as a pre-sleep tool for stressed athletes.

APEX Read Pairs well with the Thorne Magnesium Glycinate we covered in our Vol. 74 Supplement Spotlight. PharmaGABA is the on-demand stress-down tool, magnesium is the structural sleep supporter. For high-stress training weeks, deload weeks following stressful life events, or athletes navigating travel sleep, the two together do meaningful work. Take PharmaGABA 30 to 60 minutes before bed.

How to Know Your Stack Is Actually Working

The number one concern we hear from plant-based clients in Portland and Tigard is some version of "am I losing muscle?" The honest answer is that you cannot tell from the mirror or the scale, and most fitness trackers cannot either. The two tools that give you real answers are a DEXA body composition scan and routine blood work, and neither is expensive or hard to access.

A DEXA scan measures your fat mass, lean mass, and bone density with about 1 percent precision. We run them at APEX as part of our nutrition coaching and longevity programs. The most useful protocol for plant-based eaters making a real dietary change is a baseline scan, three to four months of consistent supplementation and training, then a retest. If lean mass is steady or up, your stack is working. If lean mass is dropping, the protein side of your stack needs more attention before anything else changes. Book a DEXA body composition scan in Portland here.

For the nutrient side, basic blood work covering vitamin B12, ferritin (iron stores), vitamin D, and homocysteine catches most of the supplementation-relevant gaps. If your levels look good after three months of supplementation, you can scale back. If they do not, the protocol needs adjustment. This is the kind of thing Jennie helps clients work through inside the 1-on-1 nutrition coaching program.

How to Actually Get Thorne at 25% Off

The reason this matters: Thorne does not sell to retail wholesalers, does not run public promo codes, and does not appear on Amazon at any reliable quality. The only way the public accesses professional pricing is through a Thorne practitioner partner. APEX is one. The Thorne Promo Code most people are searching for is, functionally, the APEX Thorne practitioner partner program.

The Bottom Line

Plant-based eating is a defensible, evidence-supported way to eat. The data on cardiovascular outcomes, longevity markers, and gut health is genuinely strong. The trade-off is that several specific nutrients are harder to get from plants alone, and the smart move is to supplement those rather than pretend the gaps do not exist.

Of the 10 above, the four most adults on a strict plant-based diet should consider near-mandatory are vitamin B12, iron (especially for women), creatine, and a quality plant protein. Beta-alanine matters specifically if you train high-intensity. The rest are useful tools for specific situations. None of this is medical advice. If you have known health conditions or take prescription medications, talk to your physician before adding new supplements.
