HelloPharmacist Scorecard of Final Form by Infinite Labs
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
Full disclosure
Final Form contains three active ingredients. Raspberry ketones are plant compounds studied for their potential role in weight management and hair loss, though the evidence remains limited.
L-carnitine is an amino acid that plays a role in how your cells produce energy and is established as effective for L-carnitine deficiency; it's also been studied for heart health and cholesterol support. Conjugated Linoleic Acid (CLA) is a naturally occurring fatty acid.
The capsule also contains inactive ingredients — gelatin, dicalcium phosphate, magnesium stearate, and microcrystalline cellulose — which serve as binders, fillers, and capsule material.
Does it work?
Not established
Raspberry ketones show insufficient reliable evidence for both obesity and alopecia areata (hair loss), meaning we don't yet have solid proof they work for these uses. L-carnitine is effective for L-carnitine deficiency and possibly effective for high cholesterol, heart failure, and angina — but the strength of evidence varies by condition.
The effectiveness of Conjugated Linoleic Acid is not covered in the data we hold.
How safe is it?
Well-documented data
Raspberry ketones are used safely in food but human safety data for high supplement doses is very limited. A small number of people have reported heart palpitations, rapid heartbeat, and elevated blood pressure; in rare cases, serious heart rhythm problems have occurred.
You may also experience sweating, shakiness, or diarrhea. L-carnitine is generally well tolerated at typical doses, though stomach upset (nausea, cramping, diarrhea) and a fishy body odor can happen, especially at higher doses.
Seizures are rare but documented. During pregnancy, there isn't enough safety information for raspberry ketones — the data advises against use.
For L-carnitine, safety data during pregnancy is limited and it should be used only under medical supervision. Neither ingredient has enough breastfeeding data; caution is advised with L-carnitine, and raspberry ketones should be avoided while breastfeeding.
Meds to double-check
Moderate interaction found
Before taking Final Form, check with your doctor or pharmacist if you take stimulant drugs, blood thinners (warfarin or acenocoumarol), or thyroid hormone replacement. Raspberry ketones and stimulants carry a Moderate-severity risk of heart effects.
Both raspberry ketones and L-carnitine interact with blood thinners at Moderate severity, and L-carnitine may reduce thyroid medication effectiveness.
The bottom line
Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.
This product is aimed at weight management and energy, but the evidence for raspberry ketones is weak and concerns about heart effects are real — especially if you take stimulants. If you're on a blood thinner or thyroid medication, this product needs careful review with your doctor or pharmacist before you start.
Talk it over with them first, and bring a list of everything you take.

Final Form by Infinite Labs Drug Interactions
HelloPharmacist Interaction Report
Final Form by Infinite Labs contains raspberry ketones and L-carnitine, both of which interact with medications.
The most serious concern is with raspberry ketones and stimulant drugs (Moderate severity) — the ingredient structurally resembles a known stimulant and may increase the risk of heart palpitations, elevated blood pressure, and dangerous heart rhythms.
Read the full breakdown — every affected drug type, severity by severity
Both raspberry ketones and L-carnitine interact with blood thinners (Moderate severity). Raspberry ketones may increase how much warfarin your body needs to stay effective, while L-carnitine may boost warfarin's blood-thinning effects — either way, your INR (a measure of how thin your blood is) could shift.
L-carnitine also affects acenocoumarol, another blood thinner.
Additionally, L-carnitine may reduce how well thyroid hormone replacement works by blocking the hormone from entering cells where it's needed. We could not check Conjugated Linoleic Acid — no interaction data is on file for it.
Altogether, these interactions span 191 individual medications. Use the search tool below to check your exact medications before starting.

For each ingredient in Final Form with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.
Raspberry Ketones
Stimulant Drugs
Theoretically, raspberry ketone might increase the risk of adverse cardiovascular effects with stimulant drugs.
Structurally, raspberry ketone resembles synephrine, a known stimulant agent. Heart palpitations, elevated blood pressure, coronary vasospasm, pulseless electrical activity arrest, and resistant polymorphic ventricular tachycardia have been reported in patients taking raspberry ketone.
Warfarin (Coumadin)
Theoretically, raspberry ketone might increase warfarin dose requirements.
In one case report, a patient taking warfarin 55 mg per week had a decrease in INR over a period of one month while taking raspberry ketone 250 mg daily. A warfarin dose increase to 70 mg per week was necessary to maintain a therapeutic INR while taking raspberry ketone. The mechanism for this potential interaction is not known.
L-Carnitine
Acenocoumarol (Sintrom)
Theoretically, L-carnitine might increase the anticoagulant effects of acenocoumarol.
L-carnitine might enhance the anticoagulant effects of acenocoumarol, an oral anticoagulant similar to warfarin, but shorter-acting. There are at least two case reports of INR elevation with concomitant use. In one case, a 33-year-old male with a previously stable INR had an elevated INR of 4.65 after L-carnitine was started and continued for 10 weeks. INR normalized after discontinuation of the L-carnitine-containing product.
Thyroid Hormone
Theoretically, L-carnitine might decrease the effectiveness of thyroid hormone replacement.
L-carnitine appears to act as a peripheral thyroid hormone antagonist by inhibiting entry of thyroid hormone into the nucleus of cells. Taking L-carnitine also seems to diminish some of the symptoms of hyperthyroidism.
Warfarin (Coumadin)
Theoretically, L-carnitine might increase the anticoagulant effects of warfarin.
L-carnitine might increase the anticoagulant effects of acenocoumarol, a shorter-acting oral anticoagulant similar to warfarin. There is not enough information to know whether this interaction occurs with L-carnitine and warfarin.
