Not only does the Vitamin D contribute to improved energy levels and mental focus, but the added HMB is a game-changer for muscle preservation, which is especially important for me as I navigate the challenges of aging.

Solid HMB Supplement

This HMB supplement contains a hefty quantity of capsules in a large bottle, making this a good value on its own right. The capsules are a standard/average size and have been easy to swallow with a bit of water, usually during a meal. The capsules have no taste at all, and don't seem to cause any indigestion. The D3 content is a nice plus as well.Overall the bottle is very well marked and appears trustworthy, so this seems like a solid HMB supplement for the price.

D3 Supplement with Calcium and HMB

I like that this supplement has the D3 cholecalciferol form of vitamin D in it. That is my preferred form of vitamin D since it has is more effective than D2. This supplement also contains Calcium and HMB. The Calcium and D3 combination would be helpful in maintaining strong bones and other health benefits. HMB is produced naturally in small amounts in your body, some studies have shown that supplementation may prove helpful in some people in growing muscle, muscle recovery, or reducing muscle breakdown. Given the variety of benefits this supplement has in this combination, it would seem to work well for those looking to improve health while exercising or for those looking to slow degeneration due to age or deficiencies.The capsules are easy to swallow and did not have any significant taste, they did not cause any stomach sensitivities and due to the ingredients, it will be wonderful to see health related benefits these supplements can offer.

Very potent 1,000MG HMB and Vitamin D3 Supplement!

Hydroxymethylbutyrate (HMB) is a substance found in the body that is a by-product of leucine metabolism. Leucine is one of three essential branched-chain amino acids. The body produces HMB in small amounts when it metabolizes leucine. In addition to preventing muscle protein breakdown, HMB may help improve strength and muscle mass in older adults, but evidence of a benefit for athletes is lacking. It is not a performance-enhancing drug (PED) or anabolic steroid.Vitamin D is a group of fat-soluble secosteroids responsible for increasing intestinal absorption of calcium, magnesium, and phosphate, and for many other biological effects. There are quite a few differences between vitamin D and vitamin D3, but the main difference between them is that vitamin D is a fat-soluble vitamin that regulates calcium and phosphorous levels in the body, whereas the vitamin D3 is the natural form of vitamin D produced by the body from sunlight.This potent 1,000MG HMB and Vitamin D3 Supplement is stated to be domestically manufactured at Good Manufacturing Practice (GMP) facility which is a system for ensuring that pharmaceutical products are consistently produced and controlled according to quality standards. With 90 days supply this is a great formula at a great price!

A health supplement with no foul smell, after taste or side effects.

I cannot comment on the efficacy of a health supplement. I am rating is 4 for two reason - easy to swallow and no after taste or smelly odor.Given that it is winters here and my vitamin D levels drop, looking forward to being healthier.

HMB supplements with D3 plus calcium to support your muscle health

Hydroxymethylbutyrate (HMB) is a chemical that is made when the body breaks down the amino acid leucine. Leucine is one of the building blocks of protein. In muscle cells, HMB stimulates cell growth and survival, so theoretically if you could add to this process you could build muscle.. However, there is little correlation that these supplements along with exercise lead to an increase in muscle mass. This package contains 180 capsules (90) servings. The product is non FDA regulated, so no minimum recommended daily allowance is implied. It is lab tested, contains no GMO, is made in the USA and sealed for your safety.

I Recommend!

I'd prefer liposomal capsules, but beggars can't be choosers. In terms of swallowing, it's still fairly smooth. As for its effects, I can't guarantee instant benefits, but I can say that they'll help in the long run. Whether you're sick or an athlete, I still recommend talking to your physician about what dosages are right for you.

Have a question? Ask Boscent.

What is HMB + D3 + K2?

HMB (β-hydroxy β-methylbutyrate) is a compound your body produces when it metabolizes the amino acid leucine, found in foods like beef, fish, and soybeans. Because only a small fraction of leucine converts to HMB, it's very hard to get a meaningful amount from diet alone, which is why a clinically dosed supplement matters. HMB helps preserve lean muscle and support recovery.

Vitamin D3 (cholecalciferol) supports normal muscle function, immune health, and calcium absorption, the foundation the other ingredients build on.

Vitamin K2 (as MK-7) works with D3 to direct calcium toward your bones, so the calcium you absorb supports bone strength.

Together, these three deliver complete muscle and bone support in one daily formula.

How does HMB + D3 + K2 work?

HMB helps protect and build lean muscle through two complementary mechanisms:

Reducing muscle protein breakdown — helping preserve the muscle you already have.

Supporting muscle protein synthesis — helping your body build and repair lean muscle.

Vitamin D3 supports normal muscle function and helps your body absorb calcium, while Vitamin K2 helps direct that calcium toward your bones. Together, the three work across muscle and bone for complete support.

How and when should I take it?

Take 4 capsules daily as your serving. For best results, take them consistently, with or without food. Because HMB, D3, and K2 work best when levels build over time, daily use is what drives results.

Does HMB + D3 + K2 build muscle?

Yes. HMB helps support lean muscle through two complementary mechanisms: supporting muscle protein synthesis and helping reduce muscle protein breakdown. Together, these help limit muscle damage so you can recover well and protect the muscle you build. Vitamin D3 supports normal muscle function, while K2 rounds out the formula with bone support, so you're building on a strong foundation.

What is HMB plus Vitamin D3 and K2?

HMB helps support muscle health by preserving lean muscle and supporting recovery. Vitamin D3 supports normal muscle function and helps your body absorb calcium, while Vitamin K2 helps direct that calcium toward your bones. Together, the three work across muscle and bone, so you're supported on both fronts in one daily formula.

How should I take Boscent's HMB and Vitamin D3 and K2?

Take 4 capsules once daily as your serving, with or without food. For best results, take it consistently every day, since HMB, D3, and K2 work best when levels build over time.

When can I expect to see results?

With consistent daily use, many people begin to notice improvements in strength and recovery within the first couple of weeks. More noticeable results typically take three to four weeks, depending on your training and overall routine. As with any supplement, consistency is what drives results, and individual timelines vary.

Are there any side effects associated with HMB + Vitamin D3 and K2?

HMB is generally well-tolerated, and the Vitamin D3 and K2 in this formula are included at levels well within recommended daily ranges. As with any supplement, everyone's different. If you have any concerns or notice any adverse effects, discontinue use and consult a healthcare professional.

Can I take HMB + D3 + K2 with other supplements?

Yes. HMB + D3 + K2 pairs well with everyday supplements like protein and creatine as part of a performance and recovery routine. If you take prescription medications, consult a healthcare professional first for guidance based on your individual health.

Is Boscent HMB + D3 + K2 tested for quality and safety?

Yes. Every batch is third-party lab-tested for purity and potency, so you know exactly what's in each serving. Our supplements are made in a GMP-certified facility, held to the same standard from formulation to finished bottle.

How can I trust Boscent quality?

Every Boscent product is made in a GMP-certified facility and third-party lab-tested for purity and potency, so you know exactly what's in each serving. We hold every batch to the same standard, from formulation to finished bottle.

Will my products expire?

Yes. Every bottle is stamped with a unique lot number and expiration date. For best potency, use your product within one year of opening or before the printed expiration date, whichever comes first. Because our formulas are preservative-free, we can't guarantee full potency beyond that window, so we don't recommend using expired products.
