Thorne Plant Protein - Vanilla Review
Thorne Plant Protein in Vanilla is a vegan protein powder designed to help support muscle maintenance and repair while keeping up with an active lifestyle. The formula is built from a blend of pea, brown rice, and chia protein and is meant to provide all nine essential amino acids, including branched-chain amino acids. The page describes it as a complete amino acid profile that can help with lean muscle mass, muscle recovery after exercise, healthy body composition, and healthy weight support. Each serving of two scoops provides 22 grams of protein, 130 calories, 3.5 grams of fat, and zero grams of added sugars. The product is also listed as vegan, dairy-free, gluten-free, and soy-free. Thorne states that the flavors and sweeteners are derived from natural sources and that the product is Thorne Verified Vegan. It is also NSF Certified for Sport, which the page explains means every batch is tested for compliance with label claims and for the absence of nearly 300 substances banned by many major athletic organizations. The page further notes that the product offers a good source of plant-based, non-heme iron. The product is recommended for people interested in a vegan or alternative protein option, individuals who want to maintain muscle strength, aging adults who need extra protein support, athletes and exercise enthusiasts, and anyone seeking to support healthy weight management. The directions suggest mixing two scoops with at least twelve ounces of water, juice, or another beverage, or blending it into a shake or smoothie for easy daily use. The FAQ section says the product is often gentler for people with lactose intolerance or dairy sensitivity than milk-based protein powders, although individual digestion varies. Thorne notes that its formula is tested for identity, purity, and potency, including checks for heavy metals, pesticides, and harmful microbes. The California warning on the page states a risk of reproductive harm from exposure to lead. The page also advises pregnant individuals to consult a health-care practitioner before use. The product is sold in a 40-scoop container at a listed price of $49, or $44.10 with a subscription that offers a ten percent discount.

Study, Trial or Testing Result Summary
Members Only9 human studies · 5 improved
This is a plant protein powder. Its main ingredient is a plant protein blend, listed at 28.55 grams per two-scoop serving, and no studies of that blend were provided here. The label record shows 31.5 grams of medium-chain fats, but the store listing names medium-chain fats only among the other ingredients, so the real amount is unclear and likely far lower. The studies below are about medium-chain fats, not the protein. In frail nursing home residents, 6 grams a day for 3 months improved leg performance and daily living scores compared with long-chain fat [1]. With leucine and vitamin D, 6 grams a day for 3 months raised grip strength and walking speed in frail residents [2]. In lean middle-aged and older adults, medium-chain fats plus walking for 12 weeks raised knee strength more than control [3]. Frail residents gained arm muscle area and leg function after 6 weeks [4]. In older adults with muscle loss, a mixed supplement containing medium-chain fats raised limb muscle but not grip strength [5]. In young women, medium- and long-chain fats did not change strength recovery, soreness or muscle size after hard exercise [6]. Animal and cell studies are never counted.

Review Totals and Summary

Shoppers rate this vanilla plant protein highly, and taste is the main reason. It carries about 227 ratings across the stores, with nearly all the written feedback positive and a few complaints about sweetness and settling. **What buyers say it did for them:** Several people use it to reach their protein goals, especially if they avoid animal protein. One says it "allows me to get my protein in throughout the day." Another finds the protein and calories fit their diet. One reviewer calls it a good alternative to whey for someone with dairy intolerance. Digestion comes up as well: "Good on digestion," and a store summary mentions very good digestion from another buyer. **What they complain about:** The complaints are few. Sweetness is the sharpest. One reviewer on a store page found it so sweet they could not mix even half a scoop into anything without heavy dilution, and could not manage the two-scoop serving. Another disliked that it is sweetened and wanted an unsweetened option. Others disagreed and called the sweetness normal or not too sweet. A few mention sediment: "will sediment a bit if it sits for a while." One negative review compared it unfavorably with chocolate whey, but that buyer said they ordered it by accident thinking it was the other product, so it reflects a mix-up more than a flaw. **Taste, smell and form:** Taste is the most praised feature. Buyers say "Hands down, this is the best-tasting plant-based protein I've tried" and "by far has the best flavor!" Others call it "Good taste" and "delish." Mixing gets good marks too, and one buyer says it "blends smoothly with no issues." Another mentions mixing well with fluids and fruit. One store summary notes a low grain taste and good texture, and another says the whole family likes the flavor. Another reviewer sums it up as "decent for non dairy protein powder." **Value for money:** Price is barely discussed. One store summary praises the large package size and good quality. Buyers who mention trust point to third-party testing and the NSF Certified for Sport mark, and others say they chose it for cleaner ingredients. One review says it is "the best that I have found." **Who it suits and who it did not:** It seems to suit people who want a plant-based or dairy-free protein, those who care about clean ingredients and third-party testing, and anyone who has found other plant proteins unpleasant. Repeat buyers say "it's solid product." It suits people who like a sweeter flavor less reliably: anyone sensitive to sweetness may find it too much, and those who prefer an unsweetened powder or the taste of whey may be disappointed. If you plan to let a shake sit for a while, expect some settling. Only reviews of the powder are included here. Reviews of other forms of the product were left out.

Our biohacker panel has not discussed this product’s ingredients yet.
RAL Summary
Members OnlyTier 4 for Muscle and Strength
The grade rests on studies of medium-chain fats, a minor other ingredient, while the main ingredient is the plant protein blend, for which no studies were given, so the study support is from the wrong ingredient. So it is graded Tier 4, lower than the rules alone gave.
- Emerging: not enough evidence to rank higher yet.
Where the evidence disagrees: 2 of the 9 human studies found no effect.
More Details
Members OnlyBody systems · Combine with · Possible side effects
Body systems: Musculoskeletal system, Digestive system
Combine with: To use this product for its intended purpose, combine it with creatine monohydrate for strength and lean mass, and with magnesium glycinate and vitamin D3 with K2 to support muscle function, recovery, and bone health. Leucine or EAAs can help round out the plant amino acid profile, especially around workouts. If blood sugar support is also a goal, consider adding separate targeted supplements such as berberine, chromium picolinate, alpha-lipoic acid, or Ceylon cinnamon, and for heart health consider omega-3 fish oil (EPA/DHA) and CoQ10, ideally under the guidance of a healthcare provider, particularly if taking diabetes or cardiovascular medications.
Possible side effects: No major side effects reported in the studies; reviews summarized elsewhere mention it being too sweet for some and settling if left to sit.
