14 Best Supplements for Adrenal Fatigue: Buyer’s Guide

The best supplements for adrenal fatigue are defined as the most effective natural compounds that aid in restoring the normal functioning of your adrenal glands. These supplements should meet the criteria of safety, efficacy, and bioavailability. Comparing them involves assessing their dosage, source, form, and additional ingredients. Notably, the top three supplements in this category are Magnesium, Vitamin E, and Vitamin C.

1. Magnesium

Magnesium is a critical mineral that functions as a cofactor in more than 300 enzymatic reactions in the body. It is known for its calming effect on the nervous system, which makes it a pivotal supplement for those grappling with adrenal fatigue. Magnesium aids in the regulation of stress response, enhances energy production, and supports adrenal gland health.

Potential side effects of magnesium supplements may include diarrhea, nausea, and abdominal cramping. It’s generally recommended to start with a lower dosage and gradually increase based on your body’s response. Notable brands offering the best magnesium supplements include Thorne, Now Foods, Doctor’s Best, and Nature’s Way.

When taking magnesium supplements, it’s crucial to bear in mind that different forms of magnesium have varying levels of bioavailability. Also, excessive intake may lead to gastrointestinal disturbances. The prices of magnesium supplements range widely depending on the form, dosage, and brand.

2. Vitamin E

Vitamin E is a group of eight fat-soluble compounds known for their antioxidant properties. These compounds support adrenal gland function by reducing oxidative stress, which can exacerbate adrenal fatigue. Vitamin E supplements typically come in two forms: synthetic (dl-alpha-tocopherol) and natural (d-alpha-tocopherol).

Vitamin E supplements may cause mild side effects like nausea, headache, and gastrointestinal discomfort. Notable brands offering the best Vitamin E supplements include Thorne, Solgar, Nature Made, and NOW Foods.

When using Vitamin E, be aware that high-dose supplements can interfere with blood clotting, particularly if you’re on blood-thinning medication. Also, choose natural Vitamin E when possible as it’s more bioavailable. The cost of Vitamin E supplements can vary based on the form and brand.

3. Vitamin C

Vitamin C, also known as ascorbic acid, is an essential vitamin with potent antioxidant properties. It is vital for the production of cortisol, the primary “stress hormone” produced by the adrenal glands.

Common side effects of high-dose Vitamin C supplements can include digestive discomfort and diarrhea. Brands that are known for their high-quality Vitamin C supplements include Thorne, NOW Foods, Nature’s Bounty, and Garden of Life.

When choosing a Vitamin C supplement, remember that the body cannot store this vitamin, so it needs to be taken daily. Prices for Vitamin C supplements depend on the dosage and the brand, but it is one of the most affordable vitamins on the market.

4. Calcium

Calcium is a crucial mineral that plays an integral role in nerve function and muscle contraction, which are important for the healthy functioning of the adrenal glands. It also aids in the management of stress levels.

Common side effects of calcium supplements may include constipation and bloating. Some of the top brands for calcium supplements include Thorne, Nature’s Bounty, Kirkland Signature, and Nature’s Way.

Remember that the bioavailability of calcium varies between different supplements. Also, taking calcium with food enhances absorption. The cost of calcium supplements depends on factors such as the form, dosage, and brand. It is worth noting that calcium can also be consumed naturally through diet if supplementation is not needed.

5. L-theanine

L-theanine is an amino acid found primarily in green tea. It’s known for its calming effects and its ability to reduce physiological responses to stress, making it a useful supplement for adrenal fatigue. Potential side effects are rare but may include mild headaches or drowsiness.

Some reputable brands for L-theanine include Thorne, Now Foods, Doctor’s Best, and Suntheanine. Although some supplements contain L-theanine, it is best to take L-theanine by itself to isolate the impact it has.

While using L-theanine, keep in mind that it’s non-dietary, and it’s unnecessary to take it with food. If you’re sensitive to its potential sedative effects, it’s best to take it in the evening. The cost of L-theanine supplements can vary based on the dosage and the brand.

6. Vitamin B6

Vitamin B6, also known as pyridoxine, plays an essential role in adrenal function by participating in the production of hormones like serotonin and norepinephrine, which affect mood and stress levels.

When using Vitamin B6 supplements, remember that they are best taken with food. Overconsumption can lead to nerve damage over time. Prices can fluctuate depending on the brand and the form of the supplement.

7. Cordyceps

Cordyceps is a type of fungus known for its immune-supportive and stress-regulating properties. It enhances energy, reduces fatigue, and could improve exercise performance, making it beneficial for individuals with adrenal fatigue.

Common side effects may include diarrhea, dry mouth, and mild stomach upset. Top brands offering Cordyceps supplements include Host Defense, NOW Foods, and Nature’s Way.

Remember that Cordyceps supplements may interact with immunosuppressive drugs. Also, Cordyceps sinensis and Cordyceps militaris are the most commonly used species in supplements. Prices can vary based on the brand and type of Cordyceps.

8. Passion Flower

Passion flower is a plant used for its calming effects. It’s believed to increase the levels of gamma-aminobutyric acid (GABA), a chemical the brain makes to help regulate mood.

Side effects can include dizziness, confusion, and irregular muscle action. Brands that produce Passion Flower supplements include Nature’s Way, NOW Foods, and Gaia Herbs.

When using Passion Flower supplements, be aware that they can cause drowsiness and may amplify the effects of sedative medications. The cost of these supplements varies based on the brand and form of the product.

Rhodiola Rosea is an adaptogenic herb traditionally used to help the body adapt to and resist physical, chemical, and environmental stress. It can be beneficial for adrenal fatigue by reducing cortisol levels and improving energy.

Common side effects may include dry mouth, feeling dizzy, and extra saliva production. Some reputable Rhodiola Rosea brands include NOW Foods, Gaia Herbs, and Nature’s Way.

While using Rhodiola, remember that it’s best taken in the morning to avoid potential disruptions to sleep. The cost can vary depending on the brand and the form of the supplement.

Possible side effects include digestive discomfort and, in rare cases, allergic reactions. Brands such as Nature’s Way, NOW Foods, and Gaia Herbs offer Astragalus supplements.

Note that Astragalus may interact with certain medications, including those for immune disorders. The cost of Astragalus supplements can vary based on the brand and form of the supplement.

13. Phosphatidylserine

Side effects may include insomnia and stomach upset. Top brands for phosphatidylserine include NOW Foods, Jarrow Formulas, and Nature’s Way.

Remember that phosphatidylserine is usually derived from soy. If you have a soy allergy, look for products sourced from sunflower lecithin. Prices can fluctuate depending on the dosage and the brand.
