Around that, we add a pharmacist’s high-level view of the product as a whole — what’s inside, the evidence for its stated use, how transparent the label is, and what safety data exists — so you can see the full picture in one place. It’s educational information from our licensed clinical databases and the clinical staff at HelloPharmacist — not medical advice — and we don’t sell or endorse products. Our editorial policy

HelloPharmacist Scorecard of Phospha Build by fuel:one
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Low disclosure
Phospha Build has two active ingredients. The first is a proprietary Mediator(R) Phosphatidic Acid-enriched Soy Lecithin — a compound derived from soy that contains phosphatidic acid.
The second is tart cherry fruit powder, made from sour cherry fruit. The softgel capsule itself contains inactive ingredients including medium chain triglyceride oil, gelatin, glycerin, and several food colorants.
Does it work?
Moderate evidence
The evidence for this product is limited. For the lecithin component, Alzheimer disease is rated likely ineffective, while age-related cognitive decline, anxiety, and bipolar disorder lack enough reliable evidence to rate.
For tart cherry, athletic performance is possibly effective — the strongest rating in the product — but cognitive function, exercise-induced muscle soreness, ADHD, and fibromyalgia all lack sufficient evidence to rate. Overall, the data we hold doesn't establish clear benefit for any condition.
How safe is it?
Well-documented data
Lecithin is generally considered safe in food and supplement amounts, though you should check with your doctor before using it as a supplement. Tart cherry is generally well tolerated as whole fruit, but concentrated products like this one are less studied.
The most common side effects from both ingredients are mild gastrointestinal effects — abdominal pain, diarrhea, nausea, and loose stools. Because this product contains soy-derived lecithin, anyone allergic to soy or eggs should avoid it, as it can cause allergic skin reactions.
Both ingredients are rated likely safe in pregnancy and lactation.
Meds to double-check
No known interactions
No interactions are documented in our data for the ingredients we checked.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence for its stated purpose. No medication interactions are currently documented, and safety information is well characterized.
If you're interested in athletic performance support or curious about the phosphatidic acid content, this product has no documented interactions with medications we could check. That said, the overall evidence for its benefits is thin.
Anyone with a soy or egg allergy should skip it. Before you start, run this by your own doctor or pharmacist, especially if you take any regular medications.

Clinically Dosed for More Muscle
NEW
1This clinically tested compound has been shown in clinical research to double muscle gains in test subjects compared to a placebo. In fact, these test subjects gained 5.3 lbs. of muscle and increased their strength on the leg press by 60% more than subjects using a placebo in just 8 weeks.
2In a separate phase of the same study, pre-clinical research showed that phosphatidic acid increased mTOR signalling by over 6 times compared to baseline. 3What’s more, PHOSPHA BUILD is also powered by a tested dose of tart cherry, shown in emerging research to support recovery and fight catabolism. Use PHOSPHA BUILD every day to provide both anabolic and anti-catabolic power. PHOSPHA BUILD delivers the musclebuilding factors you need to get big, and the anti-catabolic factors you need to stay that way – whatever life throws at you.
