Alpha Brain Supplement Ingredients: What Is Inside the Label

Quick answer

Alpha brain supplement ingredients, per the maker's page, include phosphatidylserine, vitamin B6, alpha GPC and Huperzia serrata extract. A retailer copy of the label shows a 2-capsule serving built on three blends, and most single amounts inside those blends are not printed. (Onnit, Alpha BRAIN)

The label01

What are the alpha brain supplement ingredients?

The alpha brain supplement ingredients are a vitamin, a plant extract and three named blends. Onnit makes the product, and the maker's page names phosphatidylserine, vitamin B6, alpha GPC and Huperzia serrata extract (Onnit, Alpha BRAIN).

That page lists no amounts. A retailer copy of the capsule label does, for a serving of 2 capsules.

How to read it02

How do you read a blend label like this one?

You read a blend label from the total down. The blend total is the combined weight of everything named in it, and the single amounts are usually not shown.

US rules allow this for ingredients without a Daily Value, as long as they are listed from most to least by weight (eCFR, 21 CFR 101.36).

  1. Find the serving

    Here it is 2 capsules, so one bottle of 60 lasts 30 days only if you take the full serving daily.

  2. Take the blend total

    The Focus Blend weighs 240 mg in all.

  3. Subtract what is shown

    Bacopa is printed at 100 mg. Alpha GPC and the clubmoss extract share the other 140 mg at most.

  4. Check the order

    Alpha GPC is named before bacopa, but bacopa's amount is the only one printed, so the order alone does not tell you much.

Safety03

What are alpha brain supplement side effects?

Alpha brain supplement side effects are not listed in the sources this desk uses, so we do not state any. The honest answer is to check each named ingredient with your pharmacist.

FDA says supplements can interact with medicines and that natural does not always mean safe (NIH ODS, Supplements: What to know). It also notes that terms like standardized or verified do not guarantee quality (NCCIH, Using supplements wisely).

Take the full ingredient list to your doctor if you use any prescription. Keep taking prescribed medicine as directed, and do not change it because of a supplement.

Cost04

What is the alpha brain supplement price?

The alpha brain supplement price is set by each seller and moves, so we print none. Work out the cost per day yourself.

Divide the bottle price by the days it lasts. If a 60-capsule bottle is used at 2 capsules a day, it lasts 30 days.

Same math for Synaptril

One capsule a day, 30 capsules a bottle. The 3-bottle pack is $72 a bottle, which is about $2.40 a day (Synaptril sales page).

Compare05

How does the Alpha Brain label compare with Synaptril?

Both products are capsules with partly hidden amounts. They differ in serving size and in what is named.

FAQ06

Alpha Brain label questions

Does Alpha Brain list the exact amount of each ingredient?

No. The retailer label gives totals for three blends and prints only a few single amounts, such as 10 mg of vitamin B6 and 100 mg of bacopa. The rest sit inside blend totals, so you cannot see how much of each one you get.

Which company makes Alpha Brain?

Onnit Labs of Austin, Texas makes it. Onnit was founded in 2010, and Unilever agreed to buy the company on April 27, 2021. We have not checked who owns it today, so confirm with the maker before you rely on that.

How many Alpha Brain capsules are in a serving?

The retailer label lists a serving as 2 capsules, with 60 capsules in the standard bottle. An 80-count Black Label version also exists. Count your own servings before you compare cost, because Synaptril is one capsule a day.

Is there a vitamin in Alpha Brain?

Yes. The label lists vitamin B6 at 10 mg per 2 capsules. It is the only vitamin line in the retailer copy we read. Everything else is a plant extract, an amino acid or another compound inside a blend.

Has the FTC taken action against Alpha Brain?

We found none in our searches, but we cannot prove that none exists. Check the FTC site and court records yourself if this matters to you. Absence of an action is not evidence that any claim is proven.

What is huperzine A doing on the Alpha Brain label?

It comes from the toothed clubmoss extract, listed as 1% huperzine A in the Focus Blend. The extract and the other Focus Blend items share 240 mg, and the single amount of huperzine is not printed. We make no claim about what it does.
