Branched-chain amino acids
Thorne Amino Complex
Featuring a blend of essential amino acids — a type of amino acid that you must get from food because your body cannot produce it — this supplement claims to help boost strength, increase muscle mass, and maximize the results of workouts (
It also contains all three branched-chain amino acids (BCAAs), a group of amino acids that may be particularly beneficial.
In fact, some studies suggest that supplementing with BCAAs could help reduce post-workout muscle damage, ease soreness, and increase time to exhaustion (
This product is available in berry and lemon flavors and can be mixed with your favorite beverage, such as water or milk, and taken 1–2 times per day or as directed by a healthcare professional.
It’s also gluten-free, vegan-friendly, and NSF Certified for Sport, so it’s a good choice for competitive athletes.
Bone and joint health
Thorne Basic Bone Nutrients
This supplement is designed to help keep your bones healthy and strong, packing four nutrients essential for bone health into each capsule.
In particular, it contains calcium, which makes up the structure of your bones and teeth, along with vitamin D, an important micronutrient that regulates calcium absorption (
It also includes a good amount of vitamin K and magnesium, which may help support bone health and maintain bone mineral density in older adults (
Like other Thorne products, Basic Bone Nutrients is free of gluten, dairy, and soy. However, keep in mind that it contains vitamin D3 derived from lanolin, or sheep’s wool, which is not suitable for vegans.
For best results, it’s recommended to take 1–4 capsules per day or use as directed by a healthcare professional.
Fish oil and omegas
Thorne Omega-3 with CoQ10
With 630 mg of combined docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) per gelcap, this supplement is a great way to bump up your intake of omega-3 fatty acids.
Research suggests that, in addition to decreasing inflammation, omega-3 fatty acids boast numerous other health benefits and may help protect against heart disease and preserve brain function in older adults (
This product also contains coenzyme Q10 (CoQ10), a compound that has been studied extensively for its ability to improve heart and blood vessel health (
It’s free of gluten, dairy, and soy and can be taken 2–3 times daily, depending on your needs.
However, note that it contains gelatin and fish oil, so vegans and vegetarians will want to opt for an omega-3 supplement derived from algae instead.
Thorne Basic Nutrients 2/Day
Thorne Basic Nutrients 2/Day is formulated with a blend of vitamins and minerals to help round out your diet and support overall health.
For example, it contains vitamin A, an important nutrient required to maintain healthy vision, as well as vitamins C and E, both of which act as antioxidants (

Thorne recommends taking 2 capsules per day or using as directed by a healthcare professional.
Keep in mind that this supplement is not appropriate for vegans. Additionally, note that there are two varieties available on the website. They contain the same nutrients and ingredients, but one version is NSF Certified for Sport and is slightly more expensive.
Thorne offers a variety of supplements intended to support sports performance, including Thorne Creatine, which provides 5 grams of creatine monohydrate per serving.
Creatine is a popular supplement among professional athletes and gym-goers alike, thanks to its ability to increase strength, prevent injuries, and promote post-workout recovery (
Thorne Creatine is free of gluten, soy, and dairy and is unflavored, so it can be easily mixed with other beverages and taken 30–90 minutes before or after exercise.
It’s also NSF Certified for Sport, meaning it’s been tested to verify that it’s free of substances banned by major athletic organizations.
FloraMend Prime Probiotic
FloraMend Prime Probiotic is formulated with 5 billion colony-forming units and 3 unique strains of probiotics, beneficial bacteria that support gut health and immunity.
In particular, it contains Bifidobacterium bifidum, which has been shown to improve seasonal allergy symptoms and immunity in human studies (
